Abstract A study was undertaken in the established benchmark soil series in different agro-ecological sub-regions of Black Soil Regions of India with the objective to assess the urease activity as a function of soil depth, bio-climate, cropping system and land use type. The urease activity declined with increase in soil depth. Maximum activity was restricted within 0–30 cm of soil depth. Cropping systems and bio-climates significantly (p < 0.01) influenced the urease activity in soil. The average urease activity in different bio-climates was in decreasing order viz. sub-humid (moist) > sub-humid (dry) > semi-arid (dry) > arid. The activity in different cropping systems was in decreasing order viz. legume- > sugarcane- > cereals- > cotton-based cropping system. Higher urease activity was observed in irrigated agro-systems as compared to the rainfed agricultural systems. High management practices increased urease activity as compared to low management. In physical properties, urease activity was negatively correlated with sand, fine clay, bulk density and available water content. Electrical conductivity, calcium carbonate and cation exchange capacity showed negative correlation in chemical properties at all the soil depths.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
