Shade tree species impacts on soil fauna and C, N, P cycles in Costa Rican organic and conventional coffee agroforestry systems

The degree of adoption of management techniques involving the increase of organic matter inputs to the soil exerted a profound influence on the total global warming potential

Soils of this class are particularly dominated by relatively high saturation, high exchangeable base (K, Ca and Mg) and organic matter relative to average values of other soil

We built 6 blocks with the more significant variables of each component: shade trees (shade percentage, species), soil (Cation Exchange Capacity, P), CFDC (incidence,

Coppicing of the shade tree and subsequent decomposition of the pruned material was the dominant mechanism for nitrogen transfer to the coffee plant, while other mechanisms only

Based on a synthesis of the reported observations, we are pre- senting a set of Tier 1 coefficients for biomass C storage for each of the 8 main AFS identified, including

Soil samples in the 0-20 cm soil layer were tested for chemical composition (soil organic matter, pH, total N, available P, exchangeable K, Ca and Mg), soil communities

Shade tree species impacts on soil nutrient availability and food web in conventional and organic coffee agroforestry..

The approach could be used to deal with constraints that are often facing extensions of oil palm plantation in flooded plains where it is necessary to consider at the same time
