Total litterfall and leaf‑litter decomposition of Theobroma grandiflorum under different agroforestry systems in the western Colombian Amazon

The objective of this study was to quantify the amount of litter accumulated on the soil and the rate of decomposition in multistrata successional agroforestry systems with Theobroma grandiflorum as mainly crop, compared to forest in the western Colombian Amazon.

Total litterfall and leaf‑litter decomposition of Theobroma grandiflorum under different agroforestry systems in the western Colombian Amazon
description The objective of this study was to quantify the amount of litter accumulated on the soil and the rate of decomposition in multistrata successional agroforestry systems with Theobroma grandiflorum as mainly crop, compared to forest in the western Colombian Amazon. Samples were collected for one year every 15 days starting in August 2013 using four collection traps distributed systematically in each AFS. In each trap the amount of total biomass was calculated (Mg ha−1) and for each component leaves, branches, flowers, fruits and seeds.To determine k, litterbags containing Theobroma grandiflorum leaves were located in each land use and were collected every 15 days from November 2013 up to 150 days, for a total of 840 litterbags (6 land uses × 10 monitoring periods × 2 mesh size × 7 replications). The annual average litterfall production was 50.8% higher in AFS (6.5 Mg ha−1) than in forestry (3.2 Mg ha−1), with leaves and branches being the major contributors with 5.2 ± 0.5 and 0.7 ± 0.2 Mg ha−1, respectively.
