Conservation agriculture (CA) has potential to changes soil physical, chemical and biological soil quality parameters compared to conventional tillage (CT) systems. The improved bio-physico-chemical soil quality in turn, affect the ecosystem services and sustainability of crop production system through counterbalancing the climate variability with the help of increasing sink for carbon sequestration within the soil. CA can also affect the functional diversity of soil microbes that essential for improved soil quality, crop production and many ecosystem services. | Conservation agriculture and soil quality An overview
