The way in which tillage systems change fertilisation practices is a complex issue. Tillage systems are sequences of operations that manipulate the soil in order to produce a crop. Operations include tilling, planting, fertilisation, pesticide application, harvesting, and residue chopping or shredding. The ways in which these operations are implemented affect the physical and chemical properties of the soil, which in turn affect plant growth. The first step in making fertiliser management decisions is to understand the practices associated with each tillage system.
