Abstract
Soil degradative processes, mechanisms that set in motion the degradative trends, include physical, chemical and biological processes. For sustainable use of soil and its protection against degradation soil quality assessment- fitness for use, and its resilience means ability to recover and identification of diagnostic recovery modules are the only options available to address this critical issue. Systematic evaluation through experimentation is needed for establishing quantitative criteria of (i) soil quality in relation to specific functions; (ii) soil degradation in relation to critical limits of key soil properties and processes; and (iii) soil resilience in relation to the ease of restoration through judicious management and discriminate use of essential input. Quantitative assessment of soil degradation can be obtained by evaluating its impact on productivity for different land uses and management systems. There is a need to develop and standardize techniques for measuring soil resilience.
