ABSTRACT:
A ground material, obtained by grinding mineral materials, is mixed with matured compost and/or sludge, obtained by the elutriation of mature compost and is matured under controlled conditions, in particular at a temperature limited to 60° C., for several weeks or several months. During the maturing process, the mineral material decomposes and biological activation occurs by means of the microorganisms that have formed during the activation phase. The product thus obtained has an improved action for promoting plant growth.
