Descripción
Organic carbon and chemical properties were measured in a degraded acid soil (Plinthic Palexerult) after 13 years of amended with a single application of several materials: sugar foam waste (E), dolomitic rock (C), gypsum (Y) or dolomitic rock and gypsum mixture (CY). The aim was to evaluate its effects on soil and crops. An application of lime (E or C), equivalent to 6.3 t/ha of calcium carbonate, incorporated into the surface at 0-18 cm was enough to increase the pH in water, from an initial value of 5.08 to 6.3 and to maintain the pH above 5.5 for at least 9 years. The gypsum did not increase the soil residual calcium as had been expected. The cultivated control plots presented the lowest calcium contents in the whole profile sampled. All the liming materials increased the exchangeable calcium in the whole profile. In contrast, the exchangeable magnesium decreased. The cultivated control (O) and Y plots had the lowest levels of magnesium and their exchangeable magnesium became depleted in the 40-80 cm horizon. The continuous cultivation and the initial liming did not significantly diminish the mean organic carbon in the 0-18 cm soil profile (2.53 %) with respect to the natural pasture unaltered plots (F). The mean forage yields harvested in the plots treated with E were significantly superior to the C and CY. The Y and O plots showed very low mean productions and both significantly lower than the rest of the treatments but similar to the F soils (954 kg. d.m./ha).
