✦ Synopsis
A process is disclosed for establishing optimum soil conditions by biologically disintegrating minerals in the presence of Ca-compounds, clay and protein-and lignocellulose-containing organic vegetable waste, as well as protein-containing organic animal waste. The process includes the following steps: a) finely crushing a mixture of minerals containing at least potassium, magnesium, phosphate and silicate, all in insoluble form; b) subjecting the vegetable and animal organic waste to an usual preliminary crushing step; c) micronizing the organic waste, preferably while homogeneously mixing it with the mixture of minerals; and d) fermenting the mixture of micronized organic waste and fineiy crushed minerals in the presence of finely crushed Ca-compound and clay, in microbially appropriate conditions.
