Description Soil health assessment of farmers’ fields in watershed villages in Medak district, Andhra
Pradesh, India showed widespread deficiencies of sulfur (S), boron (B), and zinc (Zn)
in addition to organic carbon and phosphorus (P). Participatory on-farm trials on soil
test-based application of deficient Zn, B, and S along with nitrogen (N) and P during
2009 to 2012 significantly increased crop yields over farmers’ practice (FP)—by 31%
to 45% in chickpea, 15% to 16% in cotton, 12% to 15% in paddy, and 8% to 9% in
sugarcane. Total soluble sugars in sugarcane under balanced nutrition (BN) increased
by 13%. Residual benefits of S, B, and Zn were observed in succeeding chilly crop (12%
higher yield). Benefit to cost (B:C) ratios of BN ranged between 2.8 to 8.5 in chickpea,
2.6 to 4.4 in cotton, 2.3 to 2.9 in paddy, and 7.1 to 11.4 in sugarcane, indicating
economic feasibility for scaling-up.
