Abstract:
The goal of this study is to evaluate the decomposition of poplar leaves in the field, cultivated on short rotation conditions under two different edafoclimatic conditions. The experiment was scheduled to have a duration of three years and was conducted in a plantation of poplars (Populus spp) in high density (33300 tree/ha) with drip irrigation in two different Spanish regions: Soria and Madrid. This work presents the preliminary results, which are corresponded with the initial 20 months of the study. The decomposition leaves were collected using the method of the litter-bag, which allows the evaluation of leaves decomposition, estimating the weight losses as a function of time, as well as the chemical characteristics of the remaining ones. Carbon and nitrogen contents were determined every four months, while phosphorous and potassium were evaluated every eight months. Although the initial material depends on the same genetics, the vegetal development in different soils causes differences in the composition of leaves, which influences the decomposition processes and the supply of nutrients into soils.
