The Valparaíso Region in Chile is developing a sustainable fruit production program, PER Frutícola, which includes a protocol for organic nut production, specifically walnuts. Funded by Corfo, the project aims to enhance the agroecological model by introducing green roofs, using plant materials as biofertilizers, and interacting with natural enemies. The project, led by agronomists Aart Osman and Carlos Ovalle, has found that the use of green roofs and covers like alfalfa and clover improves soil quality and reduces evaporation. The project will continue in 2021, continuing to contribute to sustainable production practices.
