 ABSTRACT

The mathematical description of N mineralization in soils like parabolic model, exponential model, hyperbolic model, zero order models etc, is a possible 3 approach to characterize and quantify the organic matters pool and mineralization constant rate. The single exponential model most widely used for soil N mineralization, although other types have also been tested. Several kinetic models are often used to estimate the kinetic of N mineralization, thus a model is selected based on the highest coefficient of determination (r2) and the lowest standard error (Wijanarko & Purwanto, 2016). The N mineralization capacity through long term incubation procedures. From their studies they proposed an asymptotic model of time course of N mineralization, making it possible to calculate the N mineralization potential of the soils (Stanford & Smith, 1972). Kinetics parameters in mineralization study can be potentially used to access the mineralization-immobilization process in soils under varying environmental and management conditions. Nitrogen-use efficiency can be enhanced through the understanding of N-mineralization potential of different organic source.

Keywords: Oragnic manure, N- mineralization, Kinetic equation.
