Short summary
We evaluated soil fertility in seven watersheds on the East India Plateau, finding that soils are acid and infertile, with low chemical fertiliser use, and organic nutrient recycling is insufficient to maintain soil fertility. This leads to inefficient rainfall use and low yields. Fertiliser rates need to increase greatly, notably in P and K. This will challenge risk-averse subsistence farmers. Field-specific fertiliser regimes are needed despite consistent fertility trends along toposequences.
