Abstract

An Incubation study was conducted from January 2020 – May 2020 under "Laboratory conditions" at the Department of Soil Science and Agricultural Chemistry, Chandra Shekhar Azad Kanpur University of Agriculture and Technology, (U.P.) to study the “Effect of added phosphorous and organic matter on the availability of phosphorous fractions in normal soil under field capacity moisture tension”. To obtain a different fraction of phosphorus under the field capacity regime all three experiments were conducted under kankar soil conditions to determine Ca-P, Al-P and Fe-P as influenced by six different treatments. The results showed that with advancement in time of incubation, the availability of Ca-P (308.2 ppm and 235.3 ppm at 0 days and 90 days of incubation period, respectively), Al-P (89.5 ppm and 44.9 ppm at 0 days and 90 days of incubation period, respectively), while Fe-P (13.8 ppm and 13.1 ppm at 0 days and 90 days of incubation period, respectively) increased marginally at field capacity in kankar soil condition. Sunhemp (T2) proved more beneficial than FYM (T3) in increasing Fe-P, Al-P, and Ca-P as also Olsen’s P content in the soil. Therefore, the application of organic matter either in the form of sun hemp with phosphorus proved very useful in improving the avoidable content of the soil.
