Abstract

We have studied the influence of a group of eleven variables (pH, lime, C/N ratio, % Total Oxidable Carbon, texture and soil salinity; amount, maturity and form of application of compost; moisture and temperature) on the mineralization rate of total organic carbon present in soil enriched with compost.
We have proposed a simple mathematic model for the mineralization of total organic carbon of soil and compost with reference to the variables determined as significant.
The model is established by taking into consideration groups of substances slowly and rapidly mineralizable, yielding order of magnitude for the half-life of both fractions in years and days respectively.
