Biomass Decomposition

The study was carried out in an agroforestry system (AFS) with cacao trees already established in La Suiza Research Center, Corpoica, located in Rionegro, Santander (Colombia). The objective was to evaluate biomass input and nutrient release rate of the species that comprise the AFS (Gmelina arbórea, Gliricidia sepium, Cedrela odorata, Theobroma cacao). The plant material decomposition process of the species was monitored with decomposition bags after 8, 15, 23, 84 and 113 days, evaluating remnant weight and nitrogen, phosphorous, potassium, calcium and magnesium content. Results showed significant differences in plant material decomposition of the species considered. The largest weight loss was found in G. arborea (87.55%) and the lowest in C. odorata (40.01%). The highest nutrient release value was found in G. arborea followed by G. sepium, and the lowest in T. cacao and C. odorata.Therefore, depending on the species that comprise the AFS there is a differential leaf biomass decomposition dynamic and hence, of the nutrient input to the soil. Of the species evaluated the highest input of new organic matter to the soil in this AFS comes from G. arborea. Altogether, the litter generated by the species evaluated contributed with 10% of the nutrients required for a cacao harvest.

Two Populations

This study evaluated the properties of juvenile wood from 7-year-old Cedrela odorata trees in two populations with the same provenance and planted in an agroforestry system with Theobroma cacao (cacao). The morphological characteristics (diameter at breast height; heartwood, sapwood, bark, and pith percentages; and eccentricity of pith), physical properties (shrinkage, green moisture content, green density, and specific gravity) and mechanical properties (modulus of rupture (MOR) and modulus of elasticity (MOE) in bending, compression stress, Janka hardness, tension stress and shear stress) were determined between two populations. The variation of the physical properties and morphological characteristics at different tree heights was also evaluated. The results showed that there were differences in both populations in terms of bark, pith, volumetric shrinkage, green moisture content, green density, MOR and MOE in bending, longitudinal compression and perpendicular tension. The results showed that population 2 presents better characteristics of growth and quality of wood for structural and furniture uses; hence, this population planted in agroforestry systems has good plantation conditions and wood quality.
