Conversion of tropical forests to croplands greatly reduces stock size of soil organic resources. Low-impact agriculture may curtail this loss in soil fertility, and favor long-term agroecosystem functioning. In east tropical Mexico, indigenous smallholders have been managing sugarcane plots without burning, fertilizing, tillaging, and removal of crop residues for the last 70 years. This study examined...
We investigated the influence of rainfall attributes on litter decomposition over an 8-year period in a well-preserved tropical dry forest ecosystem in western Mexico. We examined the relationship between the size and number of rainfall events and rainy-season litter decomposition rates and determined if this relationship varied along a landscape gradient. A mass balance approach was used to estimate...
N cycling in tropical dry forests is driven by rainfall seasonality but the mechanisms involved are not well understood. We studied the seasonal variation in N dynamics and microbial biomass in the surface litter of a tropical dry forest ecosystem in Mexico over a 2-year period. Litter was collected at 4 different times of the year to determine changes in total, soluble, and microbial C and N concentrations...
