Úspěšné plnenie čoraz náročnějších úloh v rastlinnej výrobě zvyšuje nároky na vědecký, kvalifikovaný přístup i k zvyšovaniu úrodnosti a kultúrnosti půd celým komplexem agrotechnických opatření.Successful fulfillment of increasingly demanding tasks in crop production increases the demands for a scientific, qualified approach as well as increasing the fertility and culture of soils through the whole complex of agrotechnical measures.
Nie velmi priaznivý stav úrodnosti váčšiny našich polnohospodárskych pod často súvisí s nedostatočnou zásobou a kvalitou organickej hmoty a nich nízkou sorbčnou schopnosťou. Hlavně plesčité pody trpia obvykle významným nedostatkom vody, ktorá rýchlo. preniká do hlbky, kam odnáša minerálně živiny i látky organické, takže nie je zabezpečená potřebná vlaha a výživa pre pěstované polnohospodárske plodiny. Příčinou je malý obsah a často i horšia akosť ílovej frakcie, t. j. prirodzených minerálnych sorbentov v piesčltých pódach, následkom čoho je obmedzená možnost tvorby dostatočného a dokonalého humuso-ílového komplexu, ktorý je základom priaznivej podnej štruktúry.The not very favorable fertility status of most of our agricultural areas is often related to insufficient supply and quality of organic matter and low sorption capacity. Especially moldy pods usually suffer from a significant lack of water that quickly. penetrates deep, where it carries mineral nutrients and organic substances, so it does not provide the necessary moisture and nutrition for cultivated agricultural crops. The cause is low content and often worse quality of clay fraction, ie. j. natural mineral sorbents in sandy stages, resulting in a limited possibility of forming a sufficient and perfect humus-clay complex, which is the basis of a favorable substructure.
Dnes je už dobré známe, že používanie vysokých dávok priemyselných hnojiv pri nedostatočnej zásobě organickej hmoty v pódach a nízkej sorbčnej schopnosti pódy je nielen málo efektívne, ale móže mať vplyv na obmedzovanie výšky úrod, zhoršovanie ich kvality; na okyslovaníe pod, rozrušovanie štruktúrnych agregátov, číže na zhoršovanie chemických i fyzikálnych vlastností pod.It is now well known that the use of high doses of industrial fertilizers with insufficient organic matter in the podiums and low soil sorption capacity is not only poorly effective, but can have an impact on crop yield reduction and quality degradation; on acidification below, disruption of structural aggregates, thus deterioration of chemical and physical properties below.
Problematika využitia různých melioračných hmót na báze rozmanitých priemyselných odpadov a minerálnych sorbentov, z hladiska možnosti ich využitia pri zúrodňovaní pód u nás sa výskumne riešila najma v spojitosti s riešením otázok zúrodňovania půd s nízkou sorbčnou schopnosťou [STEJSKAL, J. (1961); STEJSKAL, J. — HRUŠKA, L. (1962)].The issue of utilization of various ameliorating materials based on various industrial wastes and mineral sorbents, from the point of view of their utilization in soil reclamation in the Czech Republic, has been researched especially in connection with solving the problems of soil reclamation with low sorption capacity [STEJSKAL, J. (1961); STEJSKAL, J. - HRUSKA, L. (1962)].
Podstatou metody zúrodňovania pód aplikáciou minerálnych sorbentov je skutočnosť, že vlastnosti aplikovaných sorbentov móžu za určitých podmienok významné zlepšit potenciálnu úrodnost pod s nízkou sorbčnou schopnosťou.The essence of the soil fertilization method by the application of mineral sorbents is that the properties of the sorbents applied can, under certain conditions, significantly improve the potential fertility below low sorption capacity.
Skór, ako sa začali využívať minerálně sorbenty v poínohospodárstve uplatnili sa sorpčné metody v rozsiahlej miere v priemysle, predovšetkým na čistenie a sušenie zemného plynu [Kirkpatrick, S. D., Chem. Eng. 68, 23 (1961)], na sušenie kvapalín (Malušov, V. A. a kol. Sintetičeskije cedity, Ird. AN SSSR, Moskva 1962), odstraňovanie amoniaku z plynu [Talisman, L. V. a kol., Chim. Prom. 47, 571 (1971)], pri regenerácii nitróznych plynov (Vančura, J., Návrh koncepce ochrany ovzduší, vypracovaný pro předsednictvo vědecké rady ministra lesního a vodního hospodářství. Praha 1968), pri rafinácii cukrovarníckej stavy (Schneider,In fact, as the mineral sorbents have started to be used in agriculture, sorption methods have been applied extensively in industry, in particular for the purification and drying of natural gas [Kirkpatrick, S. D., Chem. Eng. 68, 23 (1961)], for drying liquids (Malušov, V. A. et al. Sintetičeskije cedity, Ird. AN USSR, Moscow 1962), removing ammonia from the gas [Talisman, L. V. et al., Chim. Prom. 47, 571 (1971)], in the regeneration of nitrous gases (Vančura, J., Draft Concept for Air Protection, elaborated for the Presidium of the Scientific Council of the Minister of Forestry and Water Management. Prague 1968);

SAV, Bratislava 1969), v technologii spracovania ropy [Tabakov, A. V. a kol., Neftepererabotka i neftechimija č. 4, 133 (1971)] a v mnohých dalších priemyselných oblastiach (Kol., Adsorbenty, ich polučenie, svojstva i primenenie, Trudy II. Vsesojurnogo soveščanija po adsorbentam. Nauka Leningrad 1971).F. et al., Technology des Zuckers, Vlg. MH Schaper, Hanover 1968), for bleaching oils and fats (Gregor, M., Cicel, B., Bentonite and its use, Ed. SAS, Bratislava 1969), in oil processing technology [Tabakov, AV et al., Neftepererabotka i neftechimija č. 4, 133 (1971)] and in many other industrial areas (Kol., Adsorbents, their Gluing, Confusion and Perception, Trudy II. Vsesojurnogo soveščanija po adsorbentam. Nauka Leningrad 1971).
Ako sorpčné materiály sa uplatnili predovšetkým rožne druhy aktívneho uhlia a syntetické zeolity tzv. molekulové šitá.The sorbent materials used were mainly various types of activated carbon and synthetic zeolites, the so-called. molecular sewn.
Představitelům „klasických“ sorbentov s heterogénnou štruktúrou tvořenou mikropórami, přechodnými pórami a makropórami je aktivně uhlie. Dubinin so spolupracovníkmi [Dubinin Μ. M. a kol., Zur. firč. chim. 23, 1 129 (1949)] rozdělil aktivně uhlia podta adsorpčného chovania sa k parám pri nízkých relativných tlakoch na dva limitně štruktúrne typy. K prvému štruktúrnemu typu zařadil aktivně uhlia s převážným zastúpením mikropórov, k druhému typu aktivně uhlia s makropórami. Aktivně uhlia obsahujúce vo velkej miere mikropóry i makropóry a tiež aktivně uhlia s převahou přechodných pórov nazval aktívnym uhlím zmiešaného štruktúrneho typu. V případe molekulových sít je sitoácia odlišná. Granulka molekulového šita pozostáva z primárných kryštálikov zeolitu spojených prímesou pojivá a tvoří bidisperznú štruktúru. Vo vnútri kryštálikov sú primárné póry, medzi kryštálikmi sú sekundárné póry.Representatives of “classical” sorbents with a heterogeneous structure consisting of micropores, intermediate pores and macropores are activated carbon. Dubinin with colleagues [Dubinin Μ. M. et al., Zur. fırça. chim. 23, 1 129 (1949)] divided the activated carbon according to the adsorption behavior towards vapors at low relative pressures into two limiting structure types. The first type of activated carbon was classified as active carbon with the majority of micropores, the second type of activated carbon with macropores. Activated charcoal containing to a large extent micropores and macropores and also activated charcoal predominantly transient pores called activated charcoal of a mixed structural type. In the case of molecular sieves, the sieve is different. The molecular sieve granule consists of primary crystals of zeolite bound by admixture with a binder and forms a bidisperse structure. Inside the crystals there are primary pores, between the crystals there are secondary pores.
Schopnost molekúl adsorbátu preniknúť do otvorov pórovitých materiálov je charakterizovaná kritickým rozmerom molekuly. Napr. pre dvojatómové molekuly a normálně uhlovodíky je to priemer reťazca. Kritický rozměr niektorých látok uvádza napr. Timopejev Ρ. P., Kinetika adsorbcii. Izd. AN SSSR, Moskva 1962. Kritický rozměr nie je však vždy dostatočným kritériom a.dsorpčných schopností molekúl na zeolitoch. Okrem charakteru pórovitej štruktúry závisí adsorpčná kapacita a selektivita jednotlivých sorbentov od velkosti dostupného specifického povrchu, od charakteru, velkosti a mechanizmu pósobenia povrchových sil, od teploty a parciálneho- tlaku (koncentrácie) adsorbátu.The ability of adsorbate molecules to penetrate the openings of porous materials is characterized by the critical size of the molecule. E.g. for diatomic molecules and normally hydrocarbons, this is the chain diameter. The critical dimension of some substances is shown e.g. Timopejev Ρ. P., Kinetics of Adsorption. Izd. AN USSR, Moscow 1962. However, the critical dimension is not always a sufficient criterion for the a.dsorbent ability of molecules on zeolites. In addition to the nature of the porous structure, the adsorption capacity and selectivity of the individual sorbents depend on the size of the specific surface area available, the nature, size and mechanism of surface forces, the temperature and the partial pressure (concentration) of the adsorbate.
Po úspešnej priemyselnej aplikácii syntetických zeolitov bol inicovaný záujem geo'lógov o hladanie analogických prírodných materiálov. Postupné boli v róznych častiach světa nájdené ich velké zásoby. Známe sú predovšetkým ložiská prírodných zeolitov v Japonsku, USA, Mexiku, Korei, Kube, MLR, BER, Juhoslávii, NSR, ZSSR a Itálii.After the successful industrial application of synthetic zeolites, the interest of geologists in the search for analogous natural materials was initiated. Gradually, large reserves were found in different parts of the world. The deposits of natural zeolites in Japan, USA, Mexico, Korea, Cuba, MLR, BER, Yugoslavia, West Germany, USSR and Italy are known.
Použitie prírodných zeolitov v polnohospodárstve je podmienené ich dobrými adsorpčnými a ionovýmennými vlastnoťaimi. Z celkového počtu 34 minerálnych druhov zeolitov, vyskytujúcich sa v přírodě majú prak5 tický význam najma klinoptilolit, mordenit, chabazit a erionit, ktoré okrem uvedených vlastností tvoria ložiskové akumulácie.The use of natural zeolites in agriculture is determined by their good adsorption and ion-exchange properties. Of the 34 naturally occurring mineral types of zeolites, clinoptilolite, mordenite, chabazite and erionite are of practical importance, which in addition to the above-mentioned properties constitute bearing accumulations.
V ČSSR je v súčasnosti popísaná len jedna — z hfadiska potenciálnych praktických aplikácii zeolitovej suroviny — významnejšia lokalita zeolitických tufitov na severe východoslovenskej panvy, v smere Vranov — Kučín — Nižný Hrabovec — Pusté Čemerné (Šamajová, E. — Kraus, I.: Prognózně oblasti slovenských zeolitov a možnosti ich využitia. In: Zborník referátov z konferencie SLOVZEO ‘84 s. 6—11, Vysoké Tatry 1984).In the CSSR only one is currently described - in terms of potential practical applications of zeolite raw material - a more important site of zeolite tuffites in the north of the eastern Slovak basin, in the direction of Vranov - Kučín - Nižný Hrabovec - Pusté Čemerné (Šamajová, E. - Kraus, I) In: Proceedings of the conference SLOVZEO '84 pp. 6-11, High Tatras 1984).
Hlavným horninotvorným minerálem tufitu z tohoto ložiska je klinoptilolit, ktorého obsah v hornině stanovený na základe ionovýmennej kapacity sa pohybuje od 40 do 63 % (Kozáč, J. et al. 1981). Chemické zloženie klinoptilolitu z tejto lokality je následovně (Hassler, J.: Přírodně zeolity — Přírodně molekulové šitá. Nepublikovaný materiál, 1983):The main rock-forming mineral of tuffite from this deposit is clinoptilolite, whose content in the rock determined on the basis of ion exchange capacity ranges from 40 to 63% (Kozáč, J. et al. 1981). The chemical composition of clinoptilolite from this site is as follows (Hassler, J .: Natural Zeolites - Naturally Molecular Sewn. Unpublished Material, 1983):
0,05 % 0,01 % 0,90 % 2,50 % % 4,90 %0.05% 0.01% 0.90% 2.50%% 4.90%
Z vyměnitelných katiónov převažuje Ca?+ a K+, na základe čoho možno tento prírodný zeolit zařadit medzi tzv. K—Ca typy.Of the exchangeable cations, Ca ? + And K + predominate. K — Ca types.
Zeolity sú z hfadiska chemického hydratované aiumínosilikáty, pričom základným útvarom ich kryštálovej mriežky sú gufovité útvary zložené z 24 tetraédrov SiO4.Zeolites are hydrated aiuminosilicates from the chemical point of view, with the basic formation of their crystal lattice being spherical formations composed of 24 SiO 4 tetraethers.
V týchto útvaroch sú niektoré atomy kremíka přepojené cez kyslík vazbou Si—O— —Si, čím sú v kryštáloch vytvořené vefké dutiny — otvory.In these formations, some of the silicon atoms are linked through oxygen by a Si-O-Si bond, creating large voids in the crystals.
V týchto otvoroch sú uložené katióny alebo molekuly (vody), ktoré sú tu viazané van der Waalsovými silami.These openings contain cations or molecules (water) which are bound here by van der Waals forces.
Ak cez zeolit obsahujúci napr. Ca2+ iónyIf a zeolite containing e.g. Ca 2+ ions
Cs+ > Rb+ > K+ > NH4+ > Ba2+ > Sr2+ > Na+ Cs +> Rb +> K +> NH 4 +> Ba 2+ > Sr 2+ > Na +
Táto selektivita je daná poměrným zastupením hliníka v štruktúre zeolitů. Z uvedeného vyplývá, že čím je v štruktúre zeolitů viac atómov hliníka, tým sú vačšie jeho ionecháme pretekať roztok NaCl dójde k výměně vápnika za sodík. Pri opatovnom přetékaní roztoku vápenatej s-oii, dójde k opatovuej výměně. V zeolitoch je obvyklé stechiometrické zastúpenie kremíka a hliníka ku kyslíku v pomere 1 : 2, t.j. (Si, Al) : : O — 1 : 2, pričom atomy kremíka móžu byť hliníkom substituované maximálně do 50 %. Náhradou kremíka hliníkom dochádza k narušeniu elektrónove] rovnováhy, ktorá sa kompenzuje prijatím iónov Na+, K+, Ca2+, připadne iných. V literatúre je popísaný rad selektivity klinoptilolitu voči katiónom:This selectivity is due to the relative representation of aluminum in the zeolite structure. This implies that the more aluminum atoms in the zeolite structure, the greater the ionic flow of the NaCl solution, the exchange of calcium with sodium. When the calcium solution is overflowed gently, an exchange of gaps occurs. In zeolites, the stoichiometric ratio of silicon and aluminum to oxygen is 1: 2, ie (Si, Al): 0 - 1: 2, with the silicon atoms being substituted by up to 50% by aluminum. The replacement of silicon with aluminum leads to a disturbance of the electron balance, which is compensated by the uptake of Na + , K + , Ca 2+ ions, or others. A number of clinoptilolite selectivity towards cations is described in the literature:
> Ca2+ > Fe3+ > Al3 > Mg2+ > Li+ novýmenné vlastnosti. Niektoré základné vlastnosti vybraných druhov prírodných zeolitov sú zahrnuté v tabufke:> Ca 2+ > Fe 3+ > Al 3 > Mg 2+ > Li + new properties. Some basic properties of selected types of natural zeolites are included in the table:

Významnou a společnou vlastnosťou prakticky všetkých zeolitov je stabilnosť kryštálovej mriežky, ktorá sa pri dehydratácii nerozpadá a je schopná vodu opátovne přijat.An important and common feature of virtually all zeolites is the stability of the crystal lattice, which does not disintegrate during dehydration and is capable of recuperating water.
Výsledky výskumu ukázali, že zeolitové tufy a tufity neutralizujú kyslé půdy a obzvlášť účinné regulujú uvoTňovanie amoniakálneho dusíka, ako aj ostatných základných, sekundárných a stopových rastlinných živin, najma kationického charakteru z aplikovaných minerálnych i organických hnojív. Například v Japonsku sa už niekolko· rokov používá prírodný zeolit na reguláciu vlhkosti půdy a odstraňovanie nepříjemného zápachu maštaíného hnoja a močovky pri hnojení půdy.Research results have shown that zeolite tuffs and tuffites neutralize acidic soils and are particularly effective in regulating the release of ammoniacal nitrogen as well as other essential, secondary and trace plant nutrients, particularly of cationic nature from applied mineral and organic fertilizers. For example, in Japan, natural zeolite has been used for several years to control soil moisture and to remove the unpleasant odor of manure and slurry when fertilizing the soil.
Přesnými pokusmi a meraniami sa zistilo, že dusík aplikovaný v hnojivách sa rastlinami využívá v priemere na 30—40 %, pričom straty dusíka sú tiež příčinou závažných ekologických problémov (Referáty a závěry IX. světového kongresu C. I. E. C. o priemyselných hnojivách, Budapešť, 11,—16. jún 1984). V poslednej době sa preto preverujú nové spůsoby efektívnejšieho využitia dusíka z hnojív, medzi ktorými zaoherá významné postavenie použitia inhibítorov nitrifikácie.Precise experiments and measurements have shown that nitrogen applied to fertilizers is on average used by plants at 30-40%, while nitrogen losses also cause serious environmental problems (Reports and Conclusions of the 9th CIEC World Conference on Industrial Fertilizers, Budapest, 11, - June 16, 1984). Recently, therefore, new ways of using nitrogen more efficiently from fertilizers have been investigated, among which a significant role for the use of nitrification inhibitors will play.
Vplyvom inhibítorov nitrifikácie dochádza v půdě k spomaleniu, alebo po určitú dobu až k zastaveniu premeny amoniakálneho na dusitanový dusík, čo umožňuje zníženie strát dusíka vyplavováním alebo denitriíikáciou, vzhladom k tomu, že amoniakálny dusík je v pode podstatné menej pohyblivý než dusičnanový, připadne dusitanový dusík.As a result of nitrification inhibitors, the soil slows down or, for some time, stops the conversion of ammoniacal to nitrite nitrogen, allowing the reduction of nitrogen losses by leaching or denitrification, since ammoniacal nitrogen is substantially less mobile than nitrate or nitrite nitrogen .
Nitrifikácia je biologický enzymatický proces, pri ktorom sa oxidujú redukované dusíkaté látky s přechodným uvolňováním dusitanov a ich následnou oxidáciou na dusičnany. Ždrojom dusíka pre oxidáciu sň predovšetkým amónne soli (tzv. autotrofná nitrifikácia), připadne aj organické dusíkaté látky (heterotrofná nitrifikácia). Uvedené procesy zabezpečuje Specifická fyziologická skupina mikroorganizmov — nitrifikačná mikroflóra, ktorá procesmi oxidácie dusíka- získává energiu pre svoje životné pochody.Nitrification is a biological enzymatic process in which reduced nitrogenous substances are oxidized with transient release of nitrites and their subsequent oxidation to nitrates. Nitrogen source for oxidation is mainly ammonium salts (so-called autotrophic nitrification), or organic nitrogenous substances (heterotrophic nitrification). These processes are ensured by a specific physiological group of microorganisms - nitrifying microflora, which through the processes of nitrogen oxidation - gains energy for its life processes.
V procesoch autotrofnej nitrifikácie rozlišujeme dva základné stupně. V prvom sa oxiduje amoniak na dusitany (nitritácia), v druhom pokračuje oxidácia až na dusičnany (nitratácia). Každý stupeň oxidácie zabezpečuje specifická skupina autotrofných mikroorganizmov. Nitritéciu vykonává nitritačná mikroflóra reprezentovaná baktériemi, predovšetkým z rodov Nitrosomonas, Nitrosocystis, Nitrosococcus, Nitrosolobus a Nitrosospira. Bioehemickú podstatu ich aktivity možno stručné vyjádřit zjednodušenou reakčnou schémou (Alexander, M.: So-il Nitrogen. Madison — Wisconsin, 1965, s. 309):In the processes of autotrophic nitrification we distinguish two basic stages. In the first, ammonia is oxidized to nitrites (nitritation), in the second, oxidation continues to nitrates (nitratation). Each degree of oxidation is provided by a specific group of autotrophic microorganisms. Nitrites are performed by nitritating microflora represented by bacteria, mainly from the genera Nitrosomonas, Nitrosocystis, Nitrosococcus, Nitrosolobus and Nitrosospira. The bio-chemical nature of their activity can be briefly expressed by a simplified reaction scheme (Alexander, M .: So-il Nitrogen. Madison-Wisconsin, 1965, p. 309):

Popři použití celého radu obvykle značné komplikovaných organických zlúčenín sa v sederndesiatych rokoch, v krajinách Západnej Európy začali skúšať aj podstatné jednoduchšie inhibitory anorganického charakteru. V o Velkej Británii Ashworth, J. a splupracovníci s úspechom ověřili použitie sulfidu uhličitého (sirouhlikuj — CS;i, pre inhibíciu nitrifikácie [Ashworth, J. — Briggs, G. G. — Evans, A.

In the UK, Ashworth, J. and collaborators have successfully verified the use of carbon disulfide (carbon disulfide - CS ; i , for inhibiting nitrification [Ashworth, J. - Briggs, GG - Evans, AA - Matual, J .: "Inhibiton of nitrification by nitrapyrin, carbondisulphide and trithiocarbonate.

Sulfid uhličitý (sirouhlíkj — CS2 sa ukázal ako vysoko účinný inhibitor funkcie baktérií ovplyvňujúcich oxidáciu amoniakálneho dusíka.Carbon disulfide (carbon disulphide - CS 2) has been shown to be a highly effective inhibitor of the function of bacteria affecting the oxidation of ammonia nitrogen.
Vysokú inhibičnň účinnost CS·, už pri jeho koncentrácii 10 ug.g“1 půdy hohatej na obsah humusu (2,93 % organického uhlíka) experimentálně potvrdili tiež Kudejarov, V. N. a Jenkinson, D. S. [„The effects of biocidal treatments on metabolism in soli — VI. Fumigation with carbon disulphide.“ Soil Biol. Bicchem. Vol. 8, (1976), s. 375—378). Rovnako Bremner, J. M. a Bundy, L, na základe výsledkov vykonaných pokusov konstatovali, že sulfid uhličitý bol efektivnější než patentované a komerčně dodávané inhibitory organického charakteru N-Serve, AM, ST, a to v dávke blízkej 2 hmot. dielom CS2 na 106 hmot. dielo-v půdy. [Bremner, J. M. — Bundy, L.: „Inbibition of nitrification in soils by volatile sulfur compounds.“ Soil Biol.

Fumigation with carbon disulphide. ”Soil Biol. Biochem. Vol. 8, (1976), p. 375-378). Similarly, Bremner, JM and Bundy, L, based on the results of the experiments, found that carbon disulfide was more effective than the patented and commercially supplied organic inhibitors of N-Serve, AM, ST at a dose close to 2 wt. CS 2 per 10 6 wt. work-in soil. [Bremner, JM - Bundy, L .: "Inbibition of Nitrification in Soils by Volatile Sulfur Compounds." Soil Biol. Bicchem., Vol. 6, (19741, pp. 161-165).
V poslednom období použitie CS?. na Inhibíciu nitrifikácie na základe rozsiahlych pokusov doporučili tiež podny biológivin ZSSR a Kanady [Kudejarov, V. N. — Sokolov, O. A. — Bočkarev, A.

Na možnost použitia CS2 ako inhibítora nitrifikácie u nás vo svojich prácach upozornili tiež Lišfanská, J. [Agrochémia, 22, 10, (1982), s. 285—289] a najma Balík, J. so> spolupracovníkům [Referát na konferencii „Dusík — hnojivá — půda — rastlina“, Praha 1983; Agrochémia, 24, 3, (1984), s. 69—71], ktorí publikovali výsledky spoločných výskumov vedených v sledovanej oblasti spolu so sovietskymi pódnymi biológmi [Kudejarov, V.

They found that CS 2 applied at a dose of 1 mg / 100 g of soil provided substantial inhibition of β-day nitrification processes.
Ako výhody sulfidu uhličitého (CS2) v porovnaní s dnes komerčně dodávanými inhibítormi (N-Serve, ATC) sa uvádzajú: nižšia cena, rýchlejšie prenikanie do- viičšieho okruhu v podnom profile a hlavně to, že posobí bez reziduí a je zdrojom rastlinami asimilovateťnej síry.The advantages of carbon disulfide (CS 2 ) over today's commercially available inhibitors (N-Serve, ATC) include: lower cost, faster penetration of the other circuit in the sub-profile and, above all, it works without residues and is a source of assimilable plants sulfur.
Nevýhody použitia sulfidu uhličitého (CSo.) súvisia predovšetkým s jeho fyzikáljio-chemickými vlastnosťami — vysoká, tenzia pár CS? už aj pri teplotách běžných pre jeho aplikáciu (bod varu: 46,3 °Cj, tvorba výbušných zmesi so vzduchom v širokom rozmedzí vzájemných pomerov (1—50 obj. pere. CS2. vo vzduchu pri 20 °C), nízká zápalnosť (bod zápalnoetí: 30 °Ci, relativné nízkou teplotou vznietenia (asi 100 °C), nízká rozpustnost vo vodě (0,2 % pri 0 °C; 0.014 % pri 50 °Cj a pod. Z uvedených dovodov sa hladajú možnosti aplikácie CS2, ktoré by popři bezpečnej aplikácii vytvárali předpoklady pre dlhodobejšie pSsmenjo CS2 v prde (roztoky sulfidu uhličitého v koncentrovanou) kvapalnom amoniaku, příprava vodných emulzií v roztokoch čpavkovej vody alebo- alkalických hydroxidov).The disadvantages of using carbon disulfide (CSo.) Are mainly related to its physico-chemical properties - high CS vapor pressure? even at temperatures common for its application (boiling point: 46.3 ° Cj, formation of explosive mixtures with air in a wide range of proportions (1 - 50% by volume. CS 2. in air at 20 ° C), low flammability ( ignition point: 30 ° C, relatively low flash point (about 100 ° C), low water solubility (0.2% at 0 ° C; 0.014% at 50 ° Cj, etc. ) which, in addition to safe application, would create the prerequisites for longer-term CS 2 in the fed (carbon disulfide solution in concentrated) liquid ammonia, preparation of aqueous emulsions in ammonia water or alkaline hydroxide solutions).
Teraz sa zistilo, že uvedené výhody použitia sulfidu uhličitého — CS2 ako prostriedku na inhibovanie funkcie baktérií ovplyvňujúcich oxidáciu am o oia kál něho dusíka a tiež prostriedku na dezinfekční půdy pri súčasnom odstranění, resp. minimalizaci) nevýhod sávisiacicb o jeho fyzikáhio-chemickými vlastnosťami je možné dosiahnuť využitím vynálezu. Predmetom vynálezu je prestriedok na inhibovanie funkcie nitrifikačných baktérií, pódnu dezinfekciu a komplexně zlepšenie pádných vlastností vyznačujúci sa tým, že «obsahuje minimálně 2 . 101 a maximálně 4,8 . 10”1 hmotnostných percent sulfidu uhličitého — CS·, viazanéhc na sorbenta. Ako sorbent sa používá aktivně uhlie a/alebo kostné uhlie tzv. spódium a/alebo syntetický zeolit tzv. molekulové šito a/alebo prírodný zecíit a/alebo alumina a/alebo křemelina a/alebo diatornit a/alebo polymérna koloidná kyselina křemičitá tzv. silikagél a/alebo mikropórovité sklo a/alebo grafitizované sadze a/alebo adsorpčná hlina a/alebo expandovaný perlit a/alebo vermikulit.It has now been found that the aforementioned advantages of using carbon disulfide - CS 2 as a means to inhibit the function of bacteria affecting the oxidation of ammoniacal nitrogen and also a composition for disinfectant soils while removing or disinfecting the soil. minimizing the drawbacks depending on its physicochemical properties can be achieved by utilizing the invention. SUMMARY OF THE INVENTION The present invention provides a means for inhibiting the function of nitrifying bacteria, soil disinfection, and a comprehensive improvement of the healing properties, characterized in that it comprises at least 2. 10 1 and maximum 4.8. 10 '1 percent by weight of carbon disulfide - EN ·, viazanéhc the sorbent. Activated charcoal and / or bone charcoal so-called sorbent is used as sorbent. a podium and / or a synthetic zeolite, so-called. molecular sieve and / or natural zirconium and / or alumina and / or diatomaceous earth and / or diatorite and / or polymeric colloidal silicic acid, so-called. silica gel and / or microporous glass and / or graphitized carbon black and / or adsorbent clay and / or expanded perlite and / or vermiculite.
Póry sorbenta můžu byt po naadsorbovaní CS2 čiastočne alebo úplné uzavreté látkou alebo kombináciou látok vyznačujúcicb sa adhéznymi a/alebo hydrofobizujúcimi vlastnosťami. Ako látky uvedeného typu može prostriedok obsahovat vodné sklo a/alebo lignosulfónovú kyselinu a/alebo- soli lig11 nosulfónovej kyseliny a/alebo škrob a/alebo kondenzáty močoviny s aldehydmi a/alebo parafín a/alebo vosky.The sorbent pores may be partially or completely enclosed with a substance or combination of substances exhibiting adhesion and / or hydrophobizing properties after the CS 2 has been adsorbed. As substances of the above type, the composition may comprise waterglass and / or lignosulfonic acid and / or salts of nosulfonic acid ligands and / or starch and / or urea condensates with aldehydes and / or paraffin and / or waxes.
Významnou výhodou riešenie je skutečnost, že použitím róznych reálných sorbento-v, ktoré majú zložitú heterogénnu štruktúru tvorenú pórmi rozličných rozmerov, tvaru a usporiadania sa dosiahne široká variabilita v sorpčných kapacitách, ako aj povahe sorpčných sil medzi sorbentom a molekulami CS2.A significant advantage of the solution is that by using different real sorbents having a complex heterogeneous structure formed by pores of different dimensions, shape and arrangement, a wide variability in sorption capacities as well as the nature of sorption forces between sorbent and CS 2 molecules is achieved.
Posobením podneho roztoku a podnych baktérií dochádza k postupnému dlhodobejšiemu uvoíňovaniu CS2 zo struktury sorbentu, čo umožňuje do-siahnuť časovo cielený účinok v súlade s požiadavkami pěstovaných kultur a vlastnosťami půdy. S výhodou sa ako tuhá látka používajú přírodně zeolity. Vzhtadom na velkost sorpčných sil medzi prírodným zeolitom a CS3 sa dosiahne výrazný dlhodobý inhibičný účinok a dezinfekčný účinek pri súčasnom zlepšení potenciálu úrodnosti pod v důsledku zlepšenia ich fyzlkálno-chemických vlastností, predovšetkým sorpčných a iónovýmenných schopnosti, stabilizácie obsahu vlhkosti, zníženia kyslosti a viazania NHJ' a K! iónov. Z výrobkov čsl. priemyslu sú v súčasnosti dostupné nasledujúce přípravky na báze prírodných zeolitov (výrobea — Keramické závody n. p. Košice):By impregnating the under solution and the undergrowth bacteria, CS 2 is gradually released from the sorbent structure over a longer period of time, allowing a time-targeted effect to be achieved in accordance with the requirements of cultivated crops and soil characteristics. Preferably, naturally occurring zeolites are used as the solid. Given the magnitude of sorption forces between natural zeolite and CS 3 , a significant long-term inhibitory effect and disinfectant effect is achieved while improving fertility potential as a result of improving their physico-chemical properties, in particular sorption and ion-exchange properties, moisture content stabilization, acidity reduction and NHJ binding 'a K ! ions.

Predíženie inhibičnéhoi účinku navrhovaného prostriedku je možné ďalej dosiahnu ť úpravou povrchu so-rbenta, po naadsorbovaní CS2, použitím vhodného adheziva, alebo hydrofobizujúcej látky.The prolongation of the inhibitory effect of the proposed composition can be further achieved by treating the surface of the sorbent, after CS 2 adsorption, by using a suitable adhesive or hydrophobizing agent.
