LOW-TEMPERATURE SHALE COKE NEUTRALISATION AND RECYCLING FOR IMPROVING SOIL Russian patent published in 2008 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the way of recycling and it can be used for reclamation or improvement of low-quality or damaged soil. The method includes evenly low-temperature shale coke spreading on the improving soil in autumn, then mixing with it by ploughing and subsequent microbiological oxidation. Until spreading the low-temperature coke should be mixed with peat, filings, liquid manure, droppings or other nitrogen substances and electrochemical activated water solution. The average layer of low-temperature shale coke on the improving soil is up to 30% depth of the follow-ploughing.

EFFECT: low-temperature shale coke neutralisation and recycling in huge amounts with the reforming of the contained substances into the nutrients for plants and organic matter.
