Abstract
Process of manufacture of solid and liquid organic soil ameliorators characterized in that while stirring at between 20.degree. C. and 70.degree. C. an aqueous suspension of substance rich in organic matter is incorporated to a hydrocarbon based aqueous emulsion, the mixture obtained being, as necessary, filtered in order to remove excess water; Solid and liquid organic ameliorators constituted by an organic matter coated by 0.25 to 25% by weight hydrocarbon; applications for the improvement of soils for agricultural and horticultural cultivation, re-timbering and ballasting of oil tankers.
