Abstract

In most cases, the phosphorus level of soils is too low to sustain a good crop. This necessitates a regular practice of phosphorus fertilization. However, this does not solve the problem completely because the phosphorus is rendered unavailable in several ways under different condittions in soils. The present study was taken up with the object to study the important physical and chemical constituents of soils, having a bearing on the fixation and availability of phosphorus in alkaline soils and also to observe the progressive changes in the availability of phosphorus with time following the addition of different doses of fertilizer phosphorus in the soils.
