Description Apart from water shortages, the productivity in rainfed systems of semi arid India is low due to
poor fertility status of the soils (Sahrawat et. al., 2010). However, little effort has been made to
diagnose and manage the nutrient related problems in farmers’ fields and the usual practice of
applying sub‐optimal amounts of nitrogen (N), phosphorus (P) and potassium (K) continues in
rainfed farming. For a sustainable increase in rainfed productivity, the issues related to soil fertility
need to be addressed on priority. The first objective of this communication is to show how soil
testing can be used to diagnose and manage nutrient problems in the farmers’ fields. The other
objective is to prepare nutrient maps using the GIS and delineate deficient regions from sufficient
ones for use by farmers and other stakeholders.
