METHOD OF OBTAINING THE CORRECTOR OF THE DEFICIENCES OF MICRO ELEMENTS FOR PLANT NUTRITION "MALHAM" Russian patent published in 2018 - IPC C05F5/00 C05G3/00 

FIELD: agriculture.

SUBSTANCE: invention refers to agriculture. Method of obtaining a corrector of microelement deficiency of plant nutrition from acidic sulfate waste water of the fatty acids production wastes, from soapstock of light vegetable oils, with subsequent enrichment with zinc, boron and other valuable microelements is characterized by the fact that as the basis of the base raw material, acid sulphate wastewater is used for obtained as a result of production of fatty acids from soapstock of sunflower oils, after their neutralization by defecate – filtration waste of sugar industries, pH 5.5–6.5, followed by zinc enrichment, adding dust from electric steelmaking plants, boron, adding boric acid and brine of natural bischofite, along with an increase in the content of zinc, boron, magnesium, calcium, neutralizer, and are also enriched with other macro- and microelements: nitrogen, phosphorus, potassium, iron, sulfur, molybdenum, copper, silicon, cobalt, manganese.

EFFECT: invention makes it possible to improve the ecological state of the environment, to obtain a microfertilizer being valuable for crops, a microelement deficiency corrector for plant nutrition.
