Study on the important species (mogno, andiroba, cedro) for high quality wood production. During six years of experiments the influence of light, of the mineral element supply of the soil, and of the water supply on the growth dynamics of the trees was studied in a monoculture and an enrichment plantation installed at the Research Station of the Embrapa Amazonia Ocidental (Manaus-AM-Brasil). It was that the site preparation and the plantation management had a significant influence on the light conditions, the nutrient supply, and the water supply of the plantation. In comparison in the enrichment plantation the photoactive radiation (PAR) was strongly reduced, whereas the nutrient supply of the soil was better balanced and the seasonal oscillation of the water supply of the trees was reduced compared to the monoculture.
