METHOD OF PRODUCING HIGHLY CONCETRATED SOLUTION OF MINERAL FERTILISER FOR SEED PRESOWING TREATMENT Russian patent published in 2010 - IPC A01N37/04 A01N25/02 C05D9/02 A01P21/00 

FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. Aqueous solution of mineral fertiliser for seed presowing treatment based on macro- and micro-elements with a disodium salt of ethylenediaminetetraacetic acid is prepared by mixing solutions which are diluted with water. Solution No. 1 contains salts in the following concentration: phosphorus mineral salts (P₂O₅) 0.68-1.0%; potassium (in form of K₂O) 6.2-10.7%; boron 0.27-1.013%; selenium 0.016-0.030%; molybdenum 0.26-1.09%; vanadium 0.038-0.152%; chromium 0.037-0.154%; and solution No. 2 contains salts in the following concentration: copper 2.657-3.875%; zinc 2.769-3.461%; magnesium 1.200-1.407%; iron (III) 0.198-0.521%; cobalt 0.128-0.365%; nickel 0.018-0.09%; lithium 0.047-0.142%; manganese 0.278-0.377%.

EFFECT: improved application properties of the composition for treating seeds by obtaining a highly-concentrated solution having balanced micro- and macro-elements.
