Description

Description of the invention

The invention relates to compositions for obtaining liquid nitrogen-containing fertilizers based on aqueous solutions of 2 urea ammonium nitrate with trace elements for root and foliar feeding of plants used in agriculture.

A known composition of liquid nitrogenous fertilizer for foliar feeding of plants based on urea, containing 7.5 mass.bo of a mixture of sulfates of Si, Be, Mp, Mo, 2p, Co as a micronutrient, 5 mass.Uo of a mixture of complex alkyl ether phosphate (C12) in as an emulsifier, 23.b mass.bo of the product of neutralization of 70 ethylenediaminetetraacetic acid with triethanolamine as a water evaporation inhibitor and 42.1 mass.9o of water (1.

The disadvantage of this composition is a decrease in the concentration of energizing elements. In the fertilizer, the macroelement is in the form of amides, which reduces the prolongation of the effect of the fertilizer on the plant during root or foliar feeding. 12 A known composition for obtaining a liquid nitrogen-rich fertilizer based on carbon ammoniacs with admixtures of salts of trace elements by introducing the latter in the presence of stabilizers, as which complexones of groups I, PI, PI are used (2. AS USSR Mo193539, СО5ДО/02, publ. Bull. Mo7, 13.03.67).

Although the fertilizer has good agrochemical properties, it has a high production cost of the basic carbon ammonia component, it is used only for foliar fertilization with deep embedment in the soil due to the high content of free ammonia, it causes corrosion of metal equipment.

The closest in composition is a nitrogen-containing fertilizer based on a mixture of urea and ammonium nitrate (KAS), which contains trace elements of metals obtained by treating the dust of cleaning filters (waste from the production of non-ferrous metal processing)10 - 2595 aqueous ammonia solution at their mass ratio of 1: 10 - 20. The composition of the fertilizer is as follows, mass. 9o: urea 30.0 - 36.4; ammonium nitrate 40.0 - 43.3; 725 the rest of the aqueous-ammonia filtrate, which contains trace elements in the composition of ammonia, wt.Uv: zinc 0.04 - 0.13; copper « 0.02 - 0.05; nickel (0.04 - 0.15u10, manganese (0.02 - 0.08u7107, Total nitrogen content in fertilizer 26 - 36905.

Fertilizer is used to feed agricultural plants: foliarly by spraying leaves and by rooting it into the soil. |Z. A. p. Mo1439093, IPC СО5С9/02, printed. WOULD. MoZ dated 23.11.88 |. F

The disadvantage of the well-known fertilizer is its deteriorated physical and chemical properties: the stability of the solution was not long enough (0 - 4 months). After the specified period of storage, microelements from the solution precipitate. These indicators shorten the period of storage and application of the fertilizer. - about the dust of cleaning filters - waste from the production of processing of non-ferrous metals, limits the raw material base for the production of a known fertilizer. Since the deficiency of a specific trace element (for example, 7n) is not taken into account

Zo for the plant. The ratio of trace elements in production waste is sufficiently stabilized, and this does not allow changing it to solve a specific problem, or it is too energy-consuming and unstable. The presence of nickel (Mi - the usefulness of which is little studied) and ballast substances (indicated in the prototype as "Others" reduces the nutritional value of the known fertilizer. The invention is based on the task of improving the technological and agrochemical properties of a liquid nitrogen-rich fertilizer with trace elements based on a mixture of urea and ammonium nitrate (for example, KAS-32) with the introduction of components in the composition in the form and ratio that allow to ensure the finished product: long-term stability; synergism of the action of nutrients on vegetative growth and productivity, both with foliar and during root feeding of plants; reduction of fertilizer production costs; expansion of the raw material base. sl 15 The set task is solved due to the fact that in a liquid nitrogen-rich fertilizer with trace elements based on a mixture of urea and ammonium nitrate, which includes a trace element of zinc metal, according to the invention,

Its microelement zinc metal is in a chelated form, which is obtained from technical zinc sulfate, b" aqueous technical ammonia and a complexing agent - disodium salt of ethylenediaminetetraacetic acid, as a mixture of urea and ammonium nitrate, carbamidoammonium nitrate - KAS (for example, KAS-32) is used at ( o) 50 with the following ratio of components (mass 95): also Mixture of urea and ammonium nitrate - KAS (for example, KAS-32) 99.21 - 92.10;

Zinc metal trace element in chelated form:

Technical zinc sulfate (in terms of 7p) 027-270; 52 Technical aqueous ammonia 0.15 - 1.50; in. Complexing agent - disodium salt of ethylenediaminetetraacetic acid 0.37 - 3.70.

The proposed liquid nitrogen fertilizer enhances the effect of nitrogen during foliar feeding of plants due to the trace element in chelated form. 60 The synergism of the macroelement nitrogen (M) with the microelement zinc (7p) of the proposed balanced system is not blocked by the soil-colloid complex with a high content of calcium ions (Ca 72) and is easily absorbed by the root system of plants.

The composition of the proposed fertilizer has long-term stability during storage (one year) because a stable complex is formed due to the presence of a complexing agent - disodium salt of ethylenediaminetetraacetic acid 62 (according to the prototype of Z - 4 months). -D-

The introduction of the trace element by the usual addition of zinc metal in the amount of 0.87 - 2.7wt.9o in a well-known fertilizer (for example, KAS-32) does not ensure a statistically reliable increase in plant productivity.

Liquid nitrogenous fertilizer with trace elements is obtained by the following sequence of operations:

A 2595% aqueous solution of ammonia, a complexing agent - disodium salt of ethylenediaminetetraacetic acid (Trilon B) and 1/3 of the total calculated dose of carbamidoammonium nitrate, for example, KAS-32, are loaded into the reactor with a stirrer, put into operation, heated and the ingredients are mixed. After complete dissolution of trilon B, technical salt of zinc sulfate is introduced into this solution. With constant stirring, dissolve the ingredients. 15 minutes before the end of mixing, the remaining (2/3 parts) carbamidoammonium nitrate, for example, KAS-32, is introduced.

Liquid nitrogenous fertilizer with microelements in chelated form was obtained in the reactor.

From the reactor, the solution enters a deep cleaning filter (100 μm fraction). The filtered solution is pumped into a container for cooling and storage.

The resulting solution is fed to the bottling and packaging line and then to the warehouse of finished products.

The produced liquid nitrogen-containing fertilizer will be tested according to the relevant GOST standards. Data on the effectiveness of using liquid nitrogen-rich fertilizer with trace elements on apple trees in an intensive orchard are given in the table.

The use of urea - ammonium nitrate with the trace element zinc was carried out on apple trees as root and foliar feeding. The positive effect of the tested fertilizer on the vegetative growth of plants was noted. The progressive growth of one-year sprouts with foliar and root feeding (with drip irrigation) with the new fertilizer was 69 and 4195 times higher, respectively, than when only KAS-32 was used for plant feeding. A similar positive effect from the use of a new type of fertilizer was obtained on the lateral growth of a one-year growth, where the diameter of the sprout at the base was 114 and 128965, respectively, more than when using a known fertilizer (KAS-32).

The use of an aqueous solution of urea and ammonium nitrate with zinc contributed to better establishment of generative buds. During foliar fertilization of apple plants with the tested fertilizer, an increase in the number of generative buds by 7,495 was noted compared to the known fertilizer, when root fertilization with drip irrigation, this indicator corresponded to 3,595. root feeding with drip b with Irrigation at 7095 in comparison with the variant where a well-known fertilizer (KAS-32) was tested. The application of the tested fertilizer with a trace element contained in the fertilizer in a concentration of less than 0.2795 and more than 2.795, both with X, root and foliar feeding, does not provide statistically reliable growth of the economic effect (yield).

The proposed liquid nitrogen-rich fertilizer, which contains zinc in chelated form at the ratio of nutrient elements M 28 - 3095 and 7p 0.27 - 2.795, allows to increase the productivity of intensive apple tree plantations growing on ordinary chernozems eroded when fertilizing in the period after the end of flowering due to more intensive vegetative growth of plants.

The use of a new type of fertilizer for foliar fertilizing of agricultural plants provides an increase in additional profit by 5,495 (7.3 thousand hryvnias per hectare), with root fertilization by 6,595 (9 thousand hryvnias per hectare) compared to the use of basic fertilizer KAS-32 with c due to an increase in the yield of agricultural plants. :" there is a sprout (cm) sprout (mm) buds (ball) c/ha p Foliar top dressing ХГ//11111 g » costs 1Ol/ha
