Abstract

Sustainability of Brazilian agriculture has been frequently addressed in debates about human influences on the environment. Sustainability of agricultural production is critical to meet the growing demand for food, fiber and energy, and involves economic and environmental components of agriculture. We tested the hypothesis that conservation agriculture (CA) contributes to sustainability of Brazilian soybean (Glycine max (L.) Merril) production through positive effects on one or more of the following: soil quality, grain yield and nutritional quality and growers profitability. We found that CA enhanced carbon sequestration, physical and especially biological quality of soil, which caused improved soybean grains yield, protein and flavonoids content and profit. In turn, the most expressive cropping sequence within Brazilian farmlands, the annual soybean and maize double crop (Zea mays), reduced soil physical quality with impacts on food security and agricultural sustainability. The hypothesis was proved once sustainability of Brazilian soybean production can be increased by inserting crop rotations involving cover crops in the rotation cycle.
