Effect of degree of base saturation and phosphate enrichment on the utilization of soil and fertilizer phosphorus in alluvial, black and red soils of India

, : Effect of degree of base saturation and phosphate enrichment on the utilization of soil and fertilizer phosphorus in alluvial, black and red soils of India. Technology 8(3-4): 272-276

Using Neubauer's technique the availability to rye of added and soil P in samples of surface soils was assessed in relation to the soil base saturation. The amount of added P utilized decreased in the order: K-soil > Ca-soil > 50% Ca-soil >50% K-soil > H-soil. Total P uptake increased with increasing degree of base saturation. A critical degree of P saturation is suggested below which the fixation of applied P is encouraged and above which the uptake of soil P is increased.

Purines such as adenosine, inosine, and hypoxanthine are known to have potent antiinflammatory effects. These effects generally are believed to be mediated by cell surface adenosine receptors. Here we provide evidence that purines protect against...
