ABSTRACT
Conservation agriculture systems appear to be appealing options to achieve sustainable and intensive crop production under different agroecological environments because they use available resources efficiently and maintain soil fertility. Geographical information system (GIS) in agriculture helps farmers to achieve increased production and reduced costs by enabling better management of land resources. Remote sensing plays an important role in identifying crop rotation and cropping systems for better management of land resources. Agricultural mapping is day by day becoming crucial for monitoring and management of soil and irrigation of farmlands. Spatial mapping of soil nutrients is one of the pre-requisites for adoption of precision farming; one can improve the productivity or reduce the cost of production and diminish the chance of environmental degradation caused by excess use of inputs. Agroadvisory plays a major role in resource conservation in agriculture by disseminating appropriate technologies in proper time and space.
