In response to stagnant commodity prices and the rising costs of cropping inputs, the consumption of Nitrogen and Phosphorus fertiliser inputs has been steadily declining since 2000. Consequently many agricultural farming systems are producing crops on a negative fertiliser budget. This is unsustainable both from an economic and a natural resource perspective. Additionally there is a low frequency of legume crops included in a typical crop rotation further adding to negative fertiliser budgets.
A small demonstration project funded by North West Local Land Services in N.S.W. aims to:
1. Identify legume species suitable for the Border Rivers-Gwydir catchment.
2. Assess the feasibility of opportunity cropping summer legumes to:
3. Identify the contribution of summer legumes within a cropping rotation toward sustainable farming systems as a crop with multiple purposes including, grain fodder and ground cover
4. Assess the contribution of summer legumes within a cropping rotation for positive economic and environmental outcomes:
