The influence of land-use on tropical soil chemical characteristics with emphasis to aluminium

Popis výsledku v původním jazyce

Composition of soil vegetation cover and land management influence directly the cycling of chemical elements and is a key factor for Al speciation and behavior. At the same time, Al is an important factor limiting the growth of cultural plants. Eight 1 ha plots with identical geological, climatic and geographical conditions were delimited at the North of Congo Basin (near Mbalmayo, Cameroon) in primary and secondary forests, cocoa agroforestry systems and corn field (two plots per habitat). The most important differences between particular habitats comprise vegetation cover and land management. The soil patches (64 per plot) of 1 m2 were exchanged between forests and agricultural lands. The soil was moved in two layers, layer A 0-5 cm, and layer B 5-20 cm of depth. Soil from layers A and B was sampled at each soil patch. Every three months, and soil chemical characteristics have been studied. Particular plots differ before all in their pH, content of exchangeable Al and contents of base cations. Specifically, agricultural soils revealed about 2% and 25-40% of exchangeable Al in layer A and B, respectively, while forest soils contained about 30% and 65% of exchangeable Al in layer A and B, respectively. The soil chemical characteristics clearly develop towards the state of the new site after the translocation. The Al levels reach around 50% of exchangeable Al in layer B in all environments, and exchangeable Al in layer A increased to 10% in agriculture soils and decreased to 20% in forest soils. 13th Keele Meeting on Aluminium.
