Abstract:
A controlled experiment was conducted to study the Phosphorus availability and Phosphorus fixation in four soils orders with contrasting characteristics. The results showed that, available P in the tested soil samples of Vertisols and Aridisols were found to be in high range 23.4 and 27.5 kg ha-1 respectively. The available phosphorus in tested soil samples of Inceptisols and Alfisols is found to be in low to medium range. 6.8 and 14.9 kg ha-1 respectively. Phosphorus fixation the increase in time and doses of phosphorus the phosphorus fixation also increases. About 80-95% of added phosphorus is fixed in the soils and the maximum fixation was in then Vertisols while the least fixation was observed in Alfisols at all the stages of incubation, although the differences were meagre. Phosphorus fixation was positively correlated with different pools of iron and aluminium compounds whereas, P fixation showed positive significant correlation with amorphous ferri-alumino silicate content.
