ORGANO-MINERAL FERTILIZER BASED ON LOWLAND PEAT Russian patent published in 2023 - IPC C05F11/02 

FIELD: agriculture.

SUBSTANCE: invention relates specifically to production of liquid organo-mineral fertilizers for growing crops in open ground. Organo-mineral fertilizer based on lowland peat contains peat, mineral additives in form of nitrogen, phosphorus and potassium, metal ions - zinc chelate and copper chelate, and sulphur, alkali-potassium hydroxide is used as a deoxidizer. In this case, lowland peat is used stripped from large plant residue, mixed with tap water and then under the influence of potassium hydroxide in a ratio of potassium hydroxide and peat 1:10.5-11 and subjected to cavitation-gravitational process for an hour at a temperature of 70-80 degrees to obtain a concentrate, which is filtered using a centrifuge. Nitrogen, phosphorus, potassium, metal ions - zinc chelate and copper chelate, and sulphur are added to the finished solution at the following ratio of components, kg: tap water 60, lowland peat 22, potassium hydroxide 2.0-2.1, nitrogen 5.5-6, phosphorus 0.1-0.2, potassium 1.0, zinc chelate 3.2, copper chelate 2.0, sulphur 3.0.

EFFECT: invention provides an increase in the yield of cereal crops and an improvement in the quality of grain.
