• the high molecular weight chitosan obtained primarily by chitin deacetyiation - in particular with molecular weights in the range of 1 million and above - is as such not or only to a limited extent soluble in water and aqueous alkali solutions.
• the chitosan-based components dissolve in aqueous solutions of organic and inorganic acids. It is also known that chitosan is water-soluble with a degree of deacetylation of 50%.

• the components from classes (a) and (b) used are used in such proportions of (a): (b) that the weight ratio of carbon (C): nitrogen (N) is about 6 does not exceed.
• An upper limit for the numerical value of this weight ratio of C: N is preferably about 5.
• the further development according to the invention - combined with the addition of the components to (a) and (b) - sees the simultaneous and / or time-delayed introduction of oligomeric and / or polymeric Chitosans before, which are referred to in the following description of the invention as components of class (c).
• the delayed entry of components (c) can take place both before and after the entry of components to (a) and (b).
• the invention relates to the use of phospholipids of plant origin in combination with urea and / or urea derivatives and in combination with oligomeric and / or polymeric chitosans in accordance with.
• the preferred embodiment is the introduction of the mixtures of valuable substances according to the invention in the form of aqueous preparations into the endangered soil areas before and / or in particular during plant growth.
• DE 44 37 313 A1 describes a method for improving plant growth in the fields of agriculture and forestry and horticulture by stimulating the microorganisms which live in the soil substrate and on which the plants grow.
• the European patent application EP 95 071 and the patent application WO 89/8628 describe the use of phospholipids together with macronutrients as leaf fertilizers.
• Patent application WO 93/1150 mentions the use of phospholipids as emulsifiers in fertilizer preparations.
• the invention is now based on a further finding:
• an intervention - and thus a biological control - in the highly complex living system of the soil is possible.
• the goal is the defense and / or reduction of plant parasitic nematode growth and thus the growth of selected strains of the soil fauna by stimulating and thus promoting growth of selected strains of the soil microorganism flora from the area of bacteria and / or fungi.
• rhizosphere i.e. A large population of bacterial strains (microorganism flora) is located in the soil boundary layer, which is just a few millimeters thick, in the area of the plant roots and in particular the root hairs . The same applies to the area of interaction between plant roots and native Mycorrhiza mushroom populations.
• the teaching according to the invention is based, among other things, on the knowledge that the addition of the soil additives described according to the invention apparently also results in a strengthening of those microorganism populations - and thus a strengthening of the bacterial and / or fungal strains - in the soil which counteracts the nematostatic and / or nematicidal action
• the previously known general fertilizer effect for promoting the - nematode-independent - plant growth is retained for the use of the mixtures of recyclables described.

Appropriate treatment can be if necessary, simply and / or repeatedly as often as required.
• wetting agents which are compatible with plant physiology, in particular of the O / W type, are added to the aqueous preparations of the soil additive.
• wetting agents support the spreading of the aqueous phase of valuable material in the upper soil area and thus in particular in the growth area of the plant root. This makes it possible to directly stimulate the growth of the microorganism flora strains in the rhizosphere and / or corresponding mycorrhiza strains and thus to strengthen their nematostatic and / or nematicidal action. It is understandable that even when cultivating crop plants particularly at risk from nematodes, such as sugar beets, significantly improved results can be achieved by using the teaching according to the invention.
• mixtures of valuable substances to be used according to the invention are, through the combination of selected representatives, to the previously defined subclasses of (a) - compounds of phosphorus having at least some lipophilic organic radicals - and to (b) - urea and / or urea derivatives - with simultaneous and / or delayed use of the Chitosans labeled (c).
• Preferred components for material class (a) are esters of phosphoric acid with 1- and / or polyhydric alcohols, which have lipophilic residues in their molecular structure.
• Suitable phosphoric acid esters in this sense are accordingly partial esters of fatty alcohols, which enter the required lipophilic portion into the phosphoric acid ester molecule via the hydrocarbon residue of the fatty alcohol.
• Partial esters of phosphoric acid with straight-chain fatty alcohols can be particularly suitable here, preferably at least to a substantial extent using C 6 . 10 fatty alcohols and / or their lower ethoxylates have been prepared.
• the phosphoric acid esters of higher fatty alcohols with, for example, 12 to 24 carbon atoms are also suitable, with particular importance being attached to olefinically unsaturated fatty alcohol residues.

As is well known, these are amphiphilic substances which are obtained from plant or animal cells. Preferred phospholipids in the sense of the teaching according to the invention are corresponding compounds of plant origin or phospholipid derivatives obtained therefrom. A particularly preferred representative of this class of substances for (a) are the glycerophospholipids, which are usually also referred to as lecithin. The sphingophospholipids are less preferred.
• Known and usable substances here are the diacylphospholipids, phosphatidylcholines, phosphatidylethanolamines, phosphatidylinosoles, phosphatidylserines, phosphatidylglycerols, phosphatidylglycerol phosphates, diphosphatidylglycerol, N-acylphosphatidylethanolamine and phosphatidic acid.
• the phosphatidylglycerides which are commercially available as vegetable or animal lecithins and zephaiins, are technically accessible and available in large quantities. These preparations are obtained, for example, from oils such as corn oil or cottonseed oil or soybean oil.
• Components according to the invention for subclass (a) can be enzymatically hydrolyzed glycerophospholipids (enzymatically hydrolyzed lecithin) which have a more hydrophilic character due to the elimination of a fatty acid ester.
• glycerophospholipids enzymatically hydrolyzed lecithin
• the only exceptions are products that have lost their phosphoric acid residue due to the enzymatic hydrolysis.
• urea and / or urea derivatives as essential N sources are introduced into the soil areas to be protected as valuable substances of the subclass for (b).
• the teaching according to the invention is further characterized in its important embodiments by an additional determination parameter which regulates the quantitative ratios of the component mixtures used in each case to (a) and (b). It applies here that the mixtures of the respectively selected components to these two subclasses are used in such proportions of the individual components that the calculable weight ratio of carbon (C) to nitrogen (N) in this mixture of components from (a) and (b) Numerical value of about 6 does not exceed.
• phospholipids are used as representatives of the components in (a) in mixtures of recyclable materials according to the invention, then - together with urea or urea de- derivatives as an essential source of nitrogen - here usually mixture ratios - given as parts by weight and based on the non-aqueous feedstocks - in the range from 3: 1 to 1: 3 parts of phospholipid: urea or urea derivative. It may also be preferred to use approximately equal amounts of these basic components mixed with one another.
• Suitable urine derivatives according to the invention are, in particular, the oligo- or polyureas formed by condensation of the primary urea molecule. As is well known, they are characterized in practice by a slow degradation and thus by a long-term fertilizing effect. Such a long-term effect may well be desired for the objective of biogenic nematode control according to the invention by strengthening the antagonistic and / or nematicidal potential in the soil from bacterial and / or fungal populations. As a rule, however, urea as such is also used at least in part as an N source. In this context, reference is made to a further possible modification: other known N suppliers from fertilizer technology are also suitable as part of the multi-substance mixtures to be used according to the invention.
