| Abstract | A 30-year fertilizer experiment was conducted to investigate the effects of organic manure and mineral NPK fertilizer on black soil. Four experimental treatments were used: CK, organic manure, mineral NPK fertilizer, and organic manure plus mineral fertilizer. The diversity of the nirS gene was analyzed by PCR-restriction fragment length polymorphism. The Shannon diversity index and Evenness factor, Simpson’s diversity and Shannon-Weiner indices, principal component analysis and a one-way analysis of similarities test showed that organic manure made the opposite contribution to soil diversity of nirS genes compared to mineral fertilizer treatment, which resulted in increased diversity of the nirS gene. Comparison of the phylogenetic analysis of nirS genes in the mineral fertilizer and organic manure clone libraries showed that induction by mineral fertilizer was stronger than that by organic manure, based on the types of unique nirS genotypes found in the two libraries and the evolutionary distances between them. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
