POLYMER FERTILIZER Russian patent published in 2018 - IPC C05D9/02 C05G3/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Polymer fertilizer based on a polymer matrix contains nutrients, as a polymer matrix, a polyfunctional high molecular weight compound with a molecular weight of 500-500,000 is used, containing in the side chain at least two kinds of functional groups selected from the following series: amine, hydroxyl, carbonyl, lactam, nitrile, ester, sulfonic, phosphonic, aromatic heterocycle, wherein, as nutrients, it contains at least one of the micro- and/or mesoelements in the following amounts in terms of the element: iron – 200–15,000 mg/l, boron – 70–20,000 mg/l, copper – 25–12,000 mg/l, molybdenum – 10–12,000 mg/l, zinc – 30–12,000 mg/l, manganese – 300–14,000 mg/l, cobalt – 3–7,000 mg/l, magnesium – 1,000–50,000 mg/l, sulfur – 500–50,000 mg/l, calcium – 10–10,000 mg/l, silicon – 1–6,000 mg/l.

EFFECT: invention makes it possible to increase the yield and quality of finished agricultural products at low doses of administration, to provide the possibility of using hard water for working solution (up to 168,24 °dH), as well as strengthen the actions of all components of the tank mixture.
