Influences of Planosol Fertilization with P and K on Field Crop Yields and Soil Status
Three steps of P and K fertilization (500, 1000 and 1500 kg/ha, either/or P2O5 and K2O and their second-step combination) were applied on acid soil. The highest yields were found by PK-treatment (yield increases compared to control; 12％ +30％ + 8％ + 18％ , for maize-soybean-maize-wheat rotation). P fertilization significantly influenced on soil P ( + 145％ ) , Ca ( +58％ ) , Sr ( +53％ ) and Cd ( +12％ ). K fertilization resulted in significant increases of soil K ( +77％ ) and decreases of soil Cu (-17％), and Na (-54％). However, Mg, S, Fe, Mn, Zn, Mo, Cr, Ni, Al, B, Ba, Co and Pb status were independent of the fertilization.
