FOLIAR FERTILIZER FOR GROWING FOOD CROPS Russian patent published in 2021 - IPC C05B7/00 C05C9/00 C05G3/50 C05G5/20 A01N25/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to mineral fertilizers for foliar treatment of plants containing phosphoric and nitrogen components, as well as trace elements. Foliar fertilizer for growing food crops contains nitrogen-containing material, orthophosphoric acid, trace elements, namely magnesium and zinc compounds, auxiliary substances, the fertilizer additionally contains ethoxylated aliphatic (fatty) amine, with the following ingredient content, wt.%: nitrogen-containing material 0.1-40.0, orthophosphoric acid 1.0-60.0, magnesium compound 0.1-8.0, zinc compound 0.1-10.0, ethoxylated aliphatic (fatty) amine 0.01-6.0, excipients 0.01-6.0, water being the rest, up to 100%. Urea and/or monoethanolamine are used as nitrogen-containing material, their oxides, or phosphates, or sulfates, or chlorides, or nitrates are used as magnesium and zinc compounds, and ethoxylated sterialamine, or ethoxylated oleylamine, or ethoxylated cocoylamine, or ethoxylated thalloylamine, or ethoxylated alkylamine C₁₃-C₁₅ is used as an ethoxylated aliphatic (fatty) amine.

EFFECT: proposed foliar fertilizer provides an improvement in the quality of fertilizer due to the use of surfactants, which reduce the surface tension and increases the wetting properties of the fertilizer, as well as increases the yield of agricultural crops.
