Description

Technical field

The invention relates to agriculture, in particular to fertilizers for foliar feeding of plants, which also increase resistance to diseases, which helps to increase the productivity of crops.

State of the art

A known method of feeding seed plants of leguminous herbs, US Pat. No. 2282342 MKP A01C 21/00, publ. 08/27/2006, Bull. No. 24, which consists in the fact that the testes of leguminous herbs are sprayed with an aqueous solution of microelements of boron and molybdenum (in the proportions of boron: molybdenum: para-aminobenzoic acid = 1: 1: 0.2 during the growing season, plant nutrition is carried out in two stages - stem and budding.

The disadvantage of this method is the unbalanced ratio of micro and macro elements.

The Known Method of foliar top dressing of leguminous grass pat. RF № 2284680 MKP A01C 21/00, publ. 10/10/2006, Bull. No. 28, which consists in the fact that the testes are sprayed with hydrogen sulfide water of mineral springs at a rate of 200-250 l / ha in two stages of vegetation - stalking and the beginning of budding.

The disadvantage of this method is the need for a large volume of extraction of valuable mineral water for their agricultural use, as well as the further transportation of water to consumers, during which hydrogen sulfide is released from the liquid phase.

The disadvantage of this method is the low concentration of the solution, which leads to large volumes when transporting solutions to consumers.

Closest to the claimed technical essence and the achieved result is a METHOD FOR PRODUCING TRANSPARENT LIQUID COMPLEX FERTILIZER [US Pat. RF № 2167133, MKP С05В 7/00, publ. May 20, 2001]

The essence of the method for producing transparent liquid complex fertilizers (PLCA) is to neutralize extraction phosphoric acid (EPA) with a mass fraction of P ₂ O _{5 of} 50-52% potassium-containing reagent with the introduction of sequestering agent in the amount of 0.5-5.0% before neutralization in EPA by weight of PZHKU and the subsequent introduction of macro- and microelements. Organic compounds, for example, EDTA, are used as a sequestering agent, while micronutrients are introduced into the composition of PLCU in the form of complexonates with compounds selected from the same group.

The disadvantage of this method is the precipitation of phosphorus salts of trace elements in the sediment at a molar ratio of salts of trace elements more than 4.0.
