Abstract:An evaluation of the potassium supplying power of soils, including both exchangeable and moderately available potassium, is of particular importance in predicting potash fertilizer needs for permanent pastures.
Greenhouse tests were conducted with 12 soils to measure the response of Ladino clover and common ryegrass mixtures to potash fertilization (100 pounds K2O per acre), other nutrients being supplied as needed. Laboratory data are presented to compare the plant growth response to potash fertilization with… Show more
