KR950704190A - SLOW RELEASE FERTILIZER AND ACTIVE SYNTHETIC SOIL - Google Patents

Abstract

The present invention relates to synthetic soils / fertilizers for horticultural cultivation with all soil contents essential for plant growth. The soil comprises synthetic apatite fertilizer with trace nutrients dispersed in sulfur, magnesium and calcium phosphate matrices, zeolite cation exchange media saturated with charges of potassium and nitrogen cations, and optional pH buffer. Moisture dissolves apatite and flows nutrients from the apatite matrix and the zeolite charge site.
