Increased phosphorus availability in the top soil layer of no-tillage systems can lead to a higher transformation from inorganic into organic phosphorus fractions of different labilities. The preferential phosphorus accumulation forms and fractions under the application of soluble phosphate rates in a no-tillage system were determined. During five and a half years, the following accumulated P2O5 rates: 0, 130, 180, 260, 360, 540, 720, 980, and 1.240 kg ha-1 of P2O5, were applied in the winter and/or summer, whereupon samples of the […]
