Soil phosphorus (P) fractions as affected by long-term use of inorganic and integrated fertilization under rice-wheat cropping system in loamy sand soil of Punjab, India were studied. The inorganic P fractions improved with increase in rate of P applied. The Ca-P is the dominating P fractions in these soils. The inorganic P fraction improved with fertilizer and the effect was pronounced under integrated fertilizer application. The pH and EC were negatively and significantly correlated with Sa-P… Expand
