Abstract

                                A laboratory experiment was carried out at Central Research Institute for Dry land Agriculture Hyderabad during the year 1994 to evaluate the releasing pattern and availability of phosphorus from different soil types of Ranga Reddy district of Andhra Pradesh. The results revealed that increasing levels of FYM and applied P increased the available P in all types of soils. The phosphorus availability was increased at 30 days of incubation as compared to 15 days with FYM, whereas, without FYM it increased with the increase in the incubation.
