392 Soil Functional Zone Management:a Vehicle for Enhancing Agroecosystem Services
Oral Session
ASA Section: Land Management and ConservationSoil functional zone management (SFZM) is a novel strategy for developing sustainable production systems that attempts to combine the production benefits of intensive row-crop agriculture with the environmental benefits of no-tillage. SFZM creates distinct functional zones within crop row and inter-row spaces. By incorporating decimetre-scale spatial and temporal heterogeneity, SFZM attempts to foster greater soil biodiversity and integrate complementary soil processes at the sub-field level. Such integration maximizes soil services by creating zones of ‘active turnover’, optimized for crop growth and yield (provisioning services); and adjacent zones of ‘soil building’, that promote soil structure development, carbon storage and moisture regulation (regulating and supporting services). These zones allow SFZM to secure existing agricultural productivity while avoiding or minimizing trade-offs with soil ecosystem services. Moreover, the specific properties of SFZM may enable sustainable increases in provisioning services via temporal intensification (expanding the portion of the year during which harvestable crops are grown). Through the creation of functionally distinct but interacting zones, SFZM may provide a vehicle for optimizing the delivery of multiple goods and services in agricultural systems, allowing sustainable temporal intensification while protecting and enhancing soil functioning. Team members from an AFRI-funded, multistate project will present results on various dimensions of agroecosystem performance in an SFZM system, encapsulating 5-years of coordinated research.
