Welcome to my Page!

My research focuses in developing innovations that increase the productivity, as well as the environmental and socio-economic performance of small farms in the mountainous region of the new world's tropics.

 Optimized compost with cultures of native soil microorganisms and digestates from anaerobic digesters applied to coffee seedlings

Optimized compost with cultures of native soil microorganisms and digestates from anaerobic digesters applied to coffee seedlings

My current research project focuses in the bio-optimization of compost through the integration of cultures of native soil microorganisms and digestates from anaerobic digestors. My results show that it is possible to increase the nutrient levels as well as the organic matter content, the microbial biomass and the humidity retention potential of the final compost when these alternative materials are used in the mix.

The utilization of optimized compost will help farmers rebuild the natural fertility of the soil, while decreasing their level of synthetic fertilizer use, which in turn reduces the amount of nitrous oxide emissions (a powerful greenhouse gas that has ~300 times the heating capacity of CO2), and increases the economic viability of their agroecosystems.
