SOLID FRACTION OF PRODUCT OF OXIDATIVE CRACKING OF VEGETABLE RAW MATERIAL WASTE AS WATER-ACCUMULATING NUTRITION ADDITIVE FOR SOIL Russian patent published in 2017 - IPC C09K17/50 C09K101/00 

FIELD: agriculture.

SUBSTANCE: water-accumulating nutritional additive for soil represents a solid fraction of the product of oxidative cracking of vegetable raw material waste, obtained by the treatment of vegetable raw material waste in water at room temperature with hydrogen peroxide in the presence of a catalyst based on trivalent iron oxide. The mass ratio of hydrogen peroxide to vegetable raw material waste is 0.5-1.0:1. The amount of the catalyst is 0.1-0.3% by weight with respect to the vegetable raw material waste in terms of Fe³⁺. The catalyst is obtained by heating at 60-70°C the mixture of FeCl₃⋅6H₂O, Na₂CO₃ and 0.5-1.0% aqueous ethanol with the following component ratio, wt %: FeCl₃⋅6H₂O - 0.1-0.2; Na₂CO₃ - 0.05-0.1; 0.5-1.0% aqueous ethanol - the rest. The additive for soil is characterized by the iron content of 0.03-0.04 wt %.

EFFECT: additive is provided, having high water-accumulating properties, which is sterile and environmentally safe.
