| Abstract | In order to reduce the pollution caused by nitrates from agricultural sources, the Walloon region has established a Programme of Sustainable Nitrogen Management in Agriculture. This legislation encompasses all compulsory measures mentioned in the European Directive known as ‘Nitrate Directive’ (Directive 91/676/EEC), but its scope is larger, as it defines obligations regarding storage and management of livestock manure outside vulnerable zones. The Walloon legislation is the result of a long negotiation process and represents a common understanding between the Public powers, the farmer’s unions and the water producers, purifiers and distributors. It was launched in October, 2002. Three complementary levels are concerned: the field, the whole farm and the region. At field level, the objective is to reduce nitrate losses through leaching during winter. The farmer must put in place some "good agriculture practices", particularly regarding authorised doses and periods of application of nitrogen fertilisers. At the whole farm level the farmer must maintain a balance between the organic nitrogen compound to be applied and his "land application capacity" (i.e.: the applicable quantity legally authorised). Every year, the "soil link rate" (LS) of each farm is calculated by the government administration, taking into account several factors: the number of animals on the farm, average values of nitrogen production per animal category, agricultural land surface available and authorised doses of nitrogen organic compound applicable. In vulnerable zones, organic nitrogen application is limited to 80 kg N/ha on arable land and 210 kg N/ha on grassland. Outside these vulnerable zones, the amount of livestock manure applied is limited to 120 kg N/ha on arable land and 210 kg N/ha on grassland. The organic nitrogen in excess of the "land application capacity" must be transferred to other farms that are able to value it. |

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.
