Résumé
Soil health and water scarcity problems require urgent solutions to address food security issues. The Keyline-biopolymer-biochar (KBB) enriched tunnels increase the microbial population and the water holding capacity, rendering benefits to soil health. Atmospheric water harvesting injected directly into the KBB enriched nets could improve soil health and decrease irrigation needs. The goal of this project is to create resilient agroecological systems for agricultural zones. The specific objectives are : provide an alternative water source and increase water use efficiency that can increase necromass accumulation and thus soil health ; evaluate effects of the soil management practices on the quantity and quality of the accumulated recalcitrant soil organic matter and microbial population ; increase the potential of crop resilience to the challenge of climate change ; determine the net socio-economic benefits of the agroecological practices proposed ; and transfer the technology developed to farmers and stakeholders at multiple levels. The improvement in soil health will be measured using the accumulation of recalcitrant soil organic matter, soil moisture retention and soil analysis for nutrients and enzymatic activity, and soilborne pathogens. The socio-economic study will allow us to evaluate the sustainability of the proposed methods. The proposal is submitted in response to the NIFA Program Area Priority of Soil Health (Code A1401). This work will contribute to the program goal of assessment, development, and adoption of new management/conservation practices and processes that will lead to improving or maintaining soil health and productivity while maintaining or improving environmental health and sustainability of our natural resources.
