Abstract

Ductrong district has natural and soil conditions to develop cayenne. Experiments were carried out on the slow uptake of phosphate fertilizer including apatite Lao Cai, Gafsa, Ferphos, Roc-3 to maintain of pineapple crop soil quality in three years. Both potassium chlorua and amonium sulfate put combined with phosphate fertilizers to aimed evaluate the capacity of pH, EC, phosphorus, potassium and nitrogen change in soil. The results showed that pH and EC gradually reduced, total and dissolve nitrogen content increased slightly, potassium content decreased following the years, phosphosrus content was maitained in the stable maitenace in the GAF, APA, TSP experiments.
