| Popis: | The nutrient and base status of small-holder and industrial oil-palm plantations was compared on a Ferralsol in the humid zone of the southern Ivory Coast. The plantations were about 14 years old and derived from savanna. The measured nutrient contents (C, N, P, K, Mg, Ca), the pH-values, the CEC and the calculated nutrient balances showed, that: - the concentrated applications of KCl-fertilizer in the industrial plantations (up to 216 kg KCl/ha in one application) are responsible for an accelerated acidification of these Ferralsols, already of low base saturation (S-value |
