This chapter describes cultivation of vegetables using the no-tillage cultivation system developed in Brazil (SPDH+: Sistema de Plantio Direto de Hortaliças). Based on agroecological principles, this allows more sustainable cultivation of vegetables without reliance on synthetic fertilizers and pesticides. The SPDH+ system is based on a holistic approach which combines vegetable cultivation with green soil cover, combining planted species with spontaneous plant growth. The chapter describes both underpinning principles and practical implementation with case studies.
