Agricultural Systems: Ecology

Abstract

Agricultural systems have four main inputs, cultivations, nutrients, crops and pest management, all of which are interlinked and influenced by each other. They are affected by land and water and energy availability and soil erosion. To achieve long‐term agricultural sustainability, the need for fossil‐fuel‐based inputs should be minimized and the biological and ecological inputs maximized.

Keywords: agricultural systems; agro‐ecology; sustainability resources; energy use
