| description | The litter is one of the main sources of soil nutrients, because the maintenance of forest
ecosystems occurs through the process of nutrients cycling that are present in leaf material. The aim of
this research was to evaluate the decomposition rate of Byrsonima gardneriana, correlating with soil and
climatic conditions and chemical composition. For decomposition rate evaluation, litter bags distributed
on the soil surface were utilized during the period from April/2012 to February/2013. Litter bags were
collected monthly, and sorting, cleaning and weighing of the material were carried out to quantify the
remaining material. Rainfall, water content and soil temperature were also measured monthly. The leaf
material was transported to the laboratory and it was made the determinations of Nitrogen, Carbon,
Lignin, Cellulose, Hemicellulose levels and C: N and N:lig relations. Considering the results, it was
concluded that leaves of B. gardneriana present high levels of lignin, cellulose, hemicellulose and high C: N
ratio, demonstrating the resistance of this material to decompose; and that highest rate of decomposition
occurs in the rainy season. |
