Introduction of RS & GISRS Applications in Agriculture – a Unit in SS&AC

Dept. started in 1989Soil Scientists trained in National and

International InstitutionsUsed visual products for mapping Soil ResourcesDelineated gypsum mined areas, water logged

areasModeled soil erosion by waterCarried out varietal discrimination, biomass and

yield estimation in field crops Generated DTM of micro-watershed

Agri-tech PortalAn Agritech portal with five lakh and more pages is

built and maintained by eExtension UnitReceived ‘Best e-Governance Award’ for the year

2011-12The portal provides technologies for crop production,

animal husbandryHosts success stories of farmers and farmers’

innovationsInformation on Government schemes, credit facilities

and special technologies for entrepreneurs The portal is updated on daily basis and visited by

thousands of farmers, technologists, administrators and extension personnel every day

The e-Extension Centre has multiple video conferencing facility and connects to all the TNAU College campuses, Agricultural Development Centres
