In the presente study, the K, Ca, and Mg supply of the economically important timber tree species Swietenia macrophylla Aubl. and Carapa guianensis King were investigated in three plantation systems (monoculture, mixed culture, enrichment of a secondary forest) near Manaus, Central Amazon. In order to get insight into the element input in the 5-year-old plantation systems, the K, Ca, and Mg content of precipitation, throughfall, stemflow, and litter was quantified in one-week-intervals. The element demand of the trees was quantified by element analyses of different tree fractions. The element output of the plantations caused by leaching out of the soil was calculated by soil solution samplescollected in one-week-intervals in soil depths of 10cm, 20cm and 60cm (CI-method). The element uptake of the vegetation was calculated from biomass data and the element content of different tree fractions carried out in December 1996 and in December 1997. The K, Ca, and Mg stocks of the soil were quantified by means of soil samples (exchangeable K, Ca, Mg content; total K, Ca, Mg content) and the analyses of the soil solution. Quantified input and output data of the plantations showed that the enrichment system is more stabilized with regard to K, Ca, and Mg supply than the 5-year-old monoculture and mixed culture system. Nevertheless, the quantification of the element stocks of the platations indicated high K (872/1057 g/10 m2), Ca (8l8/1502 g/10 m2), and Mg (623/1011 g/10 m2) stocks in the monoculture system and, therefore, at this state it could not be predicted in how far sustainable growth is also possible in the monoculture system, as well. Higher K, Ca, and Mg stocks were found in Carapa plantations compared to Swietenia plantations, which indicates that the stabilization of the K, Ca, and Mg stocks during the initial phase of plantations is favoured more by Carapa than by Swietenia.
