How can leaf-litter from different species growing in short rotation coppice contribute to the soil nutrient pool?

Quantifying leaf-litter and the potential contribution of essential nutrients to soil is key guaranteeing sustainability forest systems, especially in plantations under short rotation coppice, insofar as it can condition crop management such requirement for nutritional amendments. Nutrient cycling dependent on production well litter decomposition, so compare different strategies species nutrient recycling important not only determine quality quantity leaf litter, but also decomposition rate dynamics consequent incorporation organic matter into soil. Therefore, this work aims quantify analyze retranslocation rate, assess foliar biomass its concentrations, finally, evolution quality. For these purposes, eight genotypes were considered study: Populus deltoides (‘Baldo’), × canadensis (‘Ballottino’, ‘I-214′, ‘Orion’ ‘Oudenberg’); Platanus hispanica (‘Girona’), Salix matsudana spp. (‘Levante’) Robinia pseudoacacia (‘Nyirsegi’). The plantation was established central Spain with a density 10,000 cuttings ha−1. Three rotations 3 years each applied, study being carried out during first growing season second rotation. Although fall similar among species, highly specific. Different identified; greater N P found poplar, plane tree or case black locust conservation strategy, although lower all observed willow, which means that latter very rich nutrients. While even some poplar are capable releasing many released smaller variety nutrients, N, Mg immobilized leaf-litter. From perspective conserving fertility resulting from leaf-litter, highest rates, be most recommendable. However, immobilization process could satisfy requirements medium long term, thus an advantageous strategy mix dynamics.
