ABSTRACT African mahogany is a species preferred by many entrepreneurs as an investment in the forestry sector. However, there are few studies or research on the species, especially in Brazil. The aim of this work was to study the efficiency of nutrient uptake, accumulation, distribution and use in Khaya ivorensis and Khaya senegalensis, in addition to aspects of growth variables and of dry matter partitioning as a function of mineral fertilisation. Morphological, physiological and nutritional parameters were determined in the African mahogany plants 140 days after transplanting (DAT). The greatest zinc (Zn) content was detected in the shoots of both the Khaya ivorensis and Khaya senegalensis plants, accounting for more than 50% of the accumulated total of... |

ABSTRACT For the development of nutrient budget models to recommend lime and fertilizers for agricultural and forestry crops, curves of plant growth and nutrient accumulation are required. Information about how nutrients are partitioned between the different plant organs is also necessary, but still scarce for pine in Brazil. This study evaluated the growth, biomass partitioning, and nutrient dynamics in pine forests in southern Brazil. To this end, we assessed unthinned 2, 4, 6, and 8-year-old stands of Pinus taeda L. Three plots of 20 × 30 m per stand were delimited, in which three trees of different classes of diameter at breast height (DBH) were chosen. These trees were measured, felled, and the weight of their fresh components (leaves, branches, bark,... |
