ABSTRACT
An incubation study and a pot experiment were conducted from December, 2014 to May, 2015 in the laboratory and net house of the Department of Soil Science, Hajee Mohamad Danesh Science and Technology University, Dinajpur to evaluate the distribution of native and applied P in the soils. There were two treatments in this experiment e.g. control and P amendment (200 mg kg-1). The treatments were replicated thrice. The texture of HSTU farm and Kushdaha soils were sandy loam and silty clay, respectively. The range of pH and organic matter content were 4.26 to 4.89 and 1.46 to 1.72%, respectively. The initial status of labile P, Fe/Al-P and Ca/Mg-P of the different soils were 5.55 to 14.96, 48.35 to 86.44 and 10.58 to 14.74 mg Kg-1,respectively. Addition of 200 mg P per Kg soil increased the labile P, Fe/Al-P and Ca/Mg-P ranging from 58.68 to 87.07, 95.00 to 282.59 and 248.67 to 368.38 % respectively over the initial status.
