The present project was aimed toward obtaining a model of sustainable gardening practices for a horticultural intervention (HI) in Ahuazotepec, México. Different mulching materials (sand, compost, plastic, and sawdust) were evaluated in terms of sustainability and food and nutrition security using a set of locally relevant multidimensional indicators. A vegetable production field-test was established and monitored during two seasons. The global sustainability of the treatments was in the order of Compost>Plastic>Sand>Sawdust. Compost mulch was an economic, environmental, and socially sustainable option to improve vegetable and nutrient yields, and thus can be recommended for an HI in low-input systems.

本项目旨在为墨西哥Ahuazotepec的园艺干预（HI）获得可持续的园艺实践模型。使用一系列当地相关的多维指标，对可持续性以及粮食和营养安全方面的不同覆盖材料（沙子，堆肥，塑料和锯末）进行了评估。建立了蔬菜生产现场测试，并在两个季节中进行了监控。这些处理方法的全球可持续性依次为：堆肥>塑料>沙土>木屑。堆肥覆盖物是提高蔬菜和营养素产量的经济，环境和社会可持续发展的选择，因此可推荐用于低投入系统的HI。
