Abstract
Liming Florida acid Coastal Plains soils initially with more than 2.24 kg/ha of dolomitic limestone did not increase sorghum yields except where no K was applied. Liming increased the soil pH as well as the Ca and Mg content of the soil. On average, the addition of K increased sorghum grain yields. Possibly annual applications of 20 kg/ha would have been adequate because in some years there was no yield response to applied K. The maximum amount of applied P required under the conditions of this study was 55.1 kg/ha. An acid Coastal Plains soil with 200 ppm Ca, 40 ppm Mg, 80 ppm K, and 37 ppm P could be expected to produce a maximum average yield of grain sorghum of 5200 kg/ha. This maximum average yield has been exceeded in many other experiments when rainfall distribution and weather conditions at harvest were good. Yields of up to 8000 kg/ha have been obtained under these conditions
