Capacity of a soil to function in supporting important ecosystems without producing a negative interaction with the environment is referred to as soil quality (Larson and Pierce, 1991). This concept integrates physical, chemical and biological properties of the soil (Idowu et al, 2009). As there is an increased awareness regarding the impact of soil management on environmental quality and production of agriculture (Doran and Parkin, 1994), this concept of soil quality has gained increased attention all over the world (Idowu et al, 2009). These interactions determine the ability of the soil to perform some of its very important functions such as retention and release of nutrients, moisture, and resistance to degradation etc. (Larson and Pierce, 1991, Karlen et al, 1997). The influence of human use and management practices on these soil functions has given rise to the term of dynamic soil quality (Seybold et al, 1998). Some of the management practices can have a very negative effect on the ability of the soil to function. Therefore, this need of improving agricultural productivity without degrading the sustainability of the environment has led to the measurement of soil quality in relation to various processes considered important for agriculture (Doran and Jones, 1996).
It is not easy to directly measure the overall soil quality. However, the assessment includes several soil measurements, which are considered as important soil quality indicators (Larson…
