Over the past six years we have been evaluating two diverse, six-year no-till crop rotations designed to produce all the feed, forage and some tractor fuel for a typical-sized PA 65 cow, 240 acre dairy farm. Using farm scale equipment, in each 6-year crop rotation we compared enhanced conservation practices for manure or weed and insect management to typical no-till d and quality results of each year and a dairy nutrition computer model, we simulated milk production and compared the whole farm performance of two cropping scenarios (the two, 6-year enhanced conservation cropping systems compared to the two, 6-year typical no-till cropping systems). The cropping scenarios have produced the majority of the dairy feed and forage, and were profitable over a range of weather and market conditions. We also included a typical no-till, corn-soy rotation with preemptive insect control practices to help assess efficacy of IPM compared to this insurance-based management of insect pests, not to produce feed for the dairy farm. Having completed one phase of the six-year rotations, we can now assess if and how the management practices have changed agroecosystem characteristics, and evaluate how the modified cropping systems perform over additional years of weather, pest, and market dynamics. We will continue to test our original hypotheses, and some new ones designed to improve the performance of the cropping systems. To promote adoption of the enhanced conservation cropping systems, we will also assist case study commercial farms to adopt and evaluate the strategies, particularly in regions where the practices are not used. With input from the case study farmers and advisory panel, we will develop extension materials and programs and actively conduct outreach activities highlighting five dairy cropping system strategies that we have identified as most likely to enhance farm sustainability and be adopted.
Performance targets from proposal:
There are two major objectives of this project: i. to identify how to enhance the sustainability of dairy cropping systems and dairy farms in the Northeast by integrating best management practices with innovative practices and technologies, ii. to promote adoption of the cropping system practices by farmers.
