“…Another possible explanation of the lower microbial activity under NT soils is the lower soil porosity and associated reduced oxygen inputs from the atmosphere, which limits the development and activity of living organisms (Pandey et al, 2014;Nsabimana et al, 2004). The presence of more recalcitrant OM, as found in this study could be another cause of lower biological activity and soil C-CO 2 emissions.…”

“…Greater acid phosphatase activity was observed under a no-till and reduced tillage system compared to a continuous tillage system in Brazilian Cerrado Oxisol and rice grown soil (Green et al, 2007;Pandey et al, 2014). Thus, phosphatase activity is a reliable soil quality indicator since it promptly detects changes in soil organic matter caused by tillage.…”

“…A no-till system and reduction in tillage frequency results in an increase in the activities of β-glucosidase as well as microbial biomass C and N in contrast to a conventional tillage system (Pandey et al, 2014). The reduction in tillage intensity favors and increases β-glucosidase activity due to improvement in microbial biomass, more substrate availability and reduced soil disturbance (Sinsabaugh et al, 2008).…”

Soil is a fundamental resource and it is crucial to manage its quality in order to enhance agricultural productivity and environmental quality. Soil enzymes catalyze several biochemical reactions which result in the transformation of organic matter, and the release of inorganic nutrients for plant growth and nutrient cycling. Soil enzyme activities are useful biological soil quality indicators since they are operationally practical, very sensitive, integrative, easy to measure and more responsive to soil tillage and structure than other soil variables. There are several enzymes in soil, but those involved in hydrolases and the degradation of main litter components are used most often for evaluating soil quality. This paper reviews the roles of soil enzymes such as β-glucosidase, phosphatase and urease, as well as the implications of their activities for soil quality.

“…The MBC and DHA under T 5 were 17.8 and 44%, higher than that under T 4 respectively. Pandey et al [58] concluded that higher DHA in soils under NT was due to larger proportions of MBC than that in soil under CT. Higher activity of soil DHA and SMBC under NT compared to that under CT has been also reported by other researchers [43,58,59]. The accumulation of crop residues on the soil surface results in enrichment of SOM in the surface layer and the microbial activity in soil under NT and RT [47,60].…”

Over centuries and even today, traditional farming practices are well performed without any ecological degradation. However, management practice such as conservative tillage combined with nutrient and residue could increase the crop production as well as soil fertility. A three-year replicated study was conducted to assess the effects of agronomic modification of traditional farming practices on productivity and sustainability of rice (wet season)-rice (dry season) system (RRS). The replacement of farmers practice (T 2 ) with conservation effective tillage (no-till (NT)) and integrated nutrient management (INM) practice along with 30% residue retention (T 5 ) enhanced the straw, root and biomass yield of both wet season rice (WR), dry season rice (DR) and system as a whole over T 2 . Treatment T 5 recorded significantly lower soil bulk density ( b ) and higher pH than the T 2 after three years of the experiment. Further, treatment T 5 increased total soil organic carbon (2.8%), total soil organic carbon stock (2.8%), carbon sequestration rate (336.5 kg ha −1 year −1 ), cumulative carbon stock (142.9%) and carbon retention efficiency (141.0%) over T 2 of 0-20 cm depth after three year. The soil microbial biomass carbon concentration was significantly the highest under T 5 . Similarly, the dehydrogenase activity was the maximum under T 5 . Adoption of conservation tillage and nutrient management practice involving NT and INM along with residue retention can enhance the system productivity, and C and N sequestration in paddy soils is thereby contributing to the sustainability of the RRS.
