Development of profitable and robust dairy systems with an acceptable balance of emissions - LK0613

Description
Systems of dairy farming which are profitable but which have an acceptably low environmental impact will be developed to enable the industry to meet current, and probable future, requirements of legislation and voluntary codes of practice. The systems will be practicable and feasible to implement in the short to medium term. Three self-contained test systems will be established at ADAS Bridgets in the spring of 1997 and developed over three lactations. Each will utilise 36 cows and have at least two thirds of its land area in permanent grass. The remaining area will be in maize in two systems, and whole crop wheat/grass-legume ley in one system. Each system will be managed and costed independently. In addition two critical areas will be studied in more detail: (i) dietary manipulation, and (ii) maize agronomy and fertiliser requirements. These studies will focus on improving the efficiency of utilisation of nitrogen and phosphorus, and the results will be used to further improve the systems. Models of nutrient flow will be developed and validated for each system by IGER and ADAS, to form a basis for extending the findings to a wide range of situations.
