SELENIUM-CONTAINING PEAT-ZEOLITE FERTILISER WITH PROLONGED ACTION Russian patent published in 2011 - IPC C05D9/02 C05F11/02 

FIELD: chemistry.

SUBSTANCE: invention relates to agriculture, agrochemistry and particularly to organomineral fertiliser. The fertiliser contains lowland peat and natural zeolite modified with selenite ions (SeO₃)^2- in ratio of 2.3:1-2.8:2. The zeolite is saturated from 0.008-0.009% sodium selenite solution Na₂SeO₃ for 14-16 hours. The weight ratio of the natural zeolite to the sodium selenite solution is equal to 1:7-1:8.

EFFECT: invention increases maize yield, intensifies biochemical and microbiological processes, increases effectiveness of the selenium-containing peat-zeolite fertiliser and prevents pollution of the environment with chemical fertilisers.
