The particle size distribution, the nutrient content and the sorption behaviour of six solid wood and ash/charcoal residues collected in three wood-processing companies in Germany and Brazil were investigated in order to elucidate the potential of these residues for the development of new products for soil amelioration. The absorption of N, P, and K by the residues and the leaching of nutrients from impregnated samples were studied in the laboratory at substrate temperatures of 20 and 300°C. The release of elements by the impregnated samples and the sorption behaviour of ash/charcoal incorporated in the soil were also studied in the field on a temperate site (Hamburg, 53°32'N 09°59'E), on a subtropical site (Ivaí, 25°15'S 50°45'W), and on a tropical site (Aripuanã, 10°09'S 59°26'W). Under laboratory conditions the solid wood residues absorbed 2.0?9.1% of the N, 0.1?0.4% of the P, and 1.0?8.5% of the K available in the impregnation solution. At a temperature of 20°C, selected sieve fractions of the ash/charcoal residues absorbed up to twice as much as N and up to 100 times more K than the treated wood residues. The absorption of N, P, and K to the ash/charcoal residues increased significantly at a substrate temperature of 300°C compared to a substrate temperature of 20°C. In absolute numbers, the leaching of N, P, and K from the impregnated ash/charcoal residues was in the range of the release by the impregnated solid wood residues, whilst the relative rate of nutrient leaching was strongly reduced. The field experiments confirmed the results obtained in the laboratory and indicated that ash/charcoal residues are suitable raw materials for the development of new products for soil amelioration, in particular for application under humid climate conditions.

A citricultura é um dos setores do agronegócio de maior competitividade e potencial de crescimento no cenário brasileiro. O Brasil detém 30% da produção mundial de laranja e 59% da de suco de laranja (NEVES;JANK, 2006). O cultivo de citros no estado do Acre ocupa uma área aproximada de 609 ha de laranja (IBGE, 2009). Segundo Ledo et al. (1996), mesmo o estado apresentado boas condições edafoclimáticas para a exploração da cultura, a produção de laranjas não atende à demanda exigida pelo mercado local. De acordo com Ritzinger et al. (1992), dentre outros fatores, a utilização de um único porta - enxerto constitui fator limitante para o desenvolvimento local desta cultura. |
