TLDR
In this article, the N-mineralization in these plant residues as influenced by their phenol and nitrogen contents was examined and the nitrification of applied (NH4)2SO4 in these amended soils was also investigated under optimum conditions of pH.Abstract:
Soil was incubated under greenhouse conditions with plant residues having varying phenolic and nitrogen contents. The total plant material added in staggered applications every 4 months was 15 g kg−1 soil and the total incubation period was 12 months. The N-mineralization in these plant residues as influenced by their phenol and N contents was examined. The nitrification of applied (NH4)2SO4 in these amended soils was also investigated under optimum conditions of pH. A high plant-N content resulted in increased N-mineralization of plant residue, but this effect was lowered by the presence of high concentrations of polyphenols in the decomposing residue, most probably due to increased participation of N with polyphenols in the formation of humus fractions. Soils amended with phenol-rich residues did not show any inhibition of nitrification of applied (NH4)2SO4. Possible reasons are discussed. In organic matter decomposition, the quality of the leaf polyphenols appears to determine the degree of inhibition to soil nitrification.read more

Biological effects of plant residues with contrasting chemical compositions under humid tropical conditions-decomposition and nutrient release
TL;DR: In this article, the decomposition and nutrient release patterns of three woody agroforestry plant species (Acioa barteri, Gliricidia sepium and Leucaena leucocephala), maize (Zea mays) stover and rice (Oryza sativa) straw, were investigated under field conditions in the humid tropics, using litterbags of three mesh sizes (0.5, 2 and 7 mm) which allowed differential access of soil fauna.

The role of carbon-based plant secondary metabolites in decomposition in terrestrial ecosystems
TL;DR: In this paper, the authors suggest that the decreased control by lignin over annual decomposition rates of surface litter is due to a significant periodic or seasonal influence of other carbon-based plant secondary metabolites over rates in the initial phase of decomposition.
