Break crops in cropping systems: impacts on income, nitrogen and weeds locations
Aims

To determine the effect of different cropping sequences to continuous cropping.

Key messages

Brassica or legume break crops can be as profitable as wheat. In most cases, the higher the legume dry matter produced, the greater the amount of nitrogen produced. Strategic timing of operations such as hay cutting and brown manuring provide an opportunity for improved weed control.
