The P availability in soils due to the application of products of phosphate rock (PR) from Purulia heated alone or with Na2CO3 or KCI in the ratio (by weight) of 1:0.5, 1:0.25 and 1:0.15 at 300, 500, 700 and 900°C was investigated. The products of PR alone, or PR-KCI mixtures...
A study was undertaken in hot dry sub-humid region (Patloi Nala micro-watershed), under red and lateritic belt of Purulia district, West Bengal, India 23°21′to 23°23′23′′N and 86°29′47′′to 86°31′35′′E) to investigate the nature, distribution and ameliorative response of...
The highest yield was observed in diammonium phosphate treated plots followed by Purulia rock phosphate and superphosphate in conjunction with Mussoorie rock phosphate (1: 1). The P: Fe and K: P ratios proved a better tool in predicting the yield under Fe toxic soil conditions.Singh, B.P...
Dissolution and transformation of three major indigenous rock phosphates (Udaipur rock phosphate, Mussoorie rock phosphate and Purulia rock phosphate) at different P levels and soil water regimes in an acid Alfisol were studied in the laboratory. The dissolution of rock phosphate as assessed by ...
