Litter Decomposition

Litter-Decomposition Plant litter decomposition is fundamental for ecosystems productivity because of nutrient recycling, but, at the same time, by nutrient retention and phytotoxicity release, it may also hamper root proliferation negatively affecting plant nutrition and growth. The specific objectives of our research are: (i) to determine the dynamics of litter inhibitory effects during the decomposition process; (ii) to assess the relative importance of nutrient immobilization and allelopathic effects on plant growth inhibition; (iii) to predict both litter inhibitory effects and decay rates by 13C-CPMAS NMR spectroscopy and modelling.
