Description Rainfed agriculture in the dry regions is affected by water shortages. Our earlier
research showed that the deficiencies not only of major nutrients but also those of sulfur
(S) and micronutrients are holding back the potential of agricultural production
systems. The objectives of this article are to discuss the efficacy of soil testing to diagnose
nutrient deficiencies using 28,270 diverse soil samples collected from farmers’
fields in the semi-arid tropical (SAT) regions of India and to confirm the efficacy of the
soil test-based balanced nutrient management in enhancing productivity of a range of
crops in on-farm farmer participatory trials under rainfed conditions. Results of a large
numbers of on-farm trials demonstrated that soil testing is indeed an effective tool for
on-farm fertility management, a prerequisite for sustainably enhancing the productivity
in rainfed areas in the SAT regions of India. The need to strengthen the soil-testing
infrastructure in the country is emphasized.
