Abstract
A field experiment was conducted in shallow red soils in Bhavanisagar, India, to screen soil tests for the prediction of soil fertility status for sorghum. Two methods for N, two for P and five for K were tested in 20 combinations. Multiple regression analysis was used to relate the yields of sorghum, receiving 5 levels of N and 4 levels of P and K fertilizers, to the soil test values. Olsen's method was superior for determining available P, alkaline permanganate and organic carbon methods were equally good for available N, and 1N ammonium acetate and 0.1N nitric acid were equally good for available K
