Chemical and mineralogical characterization and agronomic evaluation of rock phosphates from different deposits


Agrociencia, Mexico (41): 95-112
Chemical and mineralogical characterization and agronomic evaluation of rock phosphates from different deposits
The chemical, mineralogical and fertilizing value of eight rock phosphates (six from Mexico, one from Florida and one from Morocco) are presented in tables and graphs. In pot experiments with ryegrass on two soils of pH 5.3 and 5.4 highest yields and P uptake were obtained with 200 kg P2O5/ha. Particle size differences had no significant effects.
