Nutrient management planners' feedback on New York and Pennsylvania phosphorus indices

Dairy manure is important for corn (Zea mays L.) production in New York. Optimizing corn yield while minimizing environmental loss with manure nutrients is often a challenge. A potential tool for improving N management is the Illinois Soil Nitrogen Test (ISNT), which estimates amino sugar N, a pool of potentially mineralizable N for corn uptake. The objectives of this study were to determine (1) the short-term effects of manure applications on ISNT-N, and (2) the longer-term impacts of annual additions of composted and liquid dairy manure on ISNT-N. A 6-wk incubation study showed that NH4-N from manure temporarily (< 2 wk) increased ISNT results. A 4-yr field study was conducted with annual spring applications of two rates of composted dairy manure (45 and 77 Mg ha-1) and two liquid dairy manure rates (63.5 and 180 kL ha-1). Results showed that ISNT-N slightly decreased over time in check plots (no manure or fertilizer additions) and that increases in ISNT-N over time in compost and liquid manure amended plots were consistent with changes in N credits currently given to manures in New York. Our results suggest that the ISNT accounts for N in previously applied compost and manure amendments, but that samples should not be taken within 2-wk following manure addition.

Citizen Engagement

The creation of natural resource management and conservation strategies can be affected by engagement with local citizens and competing interests between agencies and stakeholders at the varying levels of governance. This paper examines the role of local engagement and the interaction between governance levels on the outcomes of nutrient management policy, a specific area of natural resource conservation and management. Presented are two case studies of the New York City and Chesapeake Bay Watersheds in the US. These case studies touch upon the themes of local citizen engagement and governance stakeholder interaction in changing nutrient management to improve water quality. An analysis of these cases leads to several key considerations for the creation and implementation of nutrient management and natural resource management more broadly, including the importance of: local citizen engagement, government brokering and cost sharing; and the need of all stakeholders to respect each other in the policy creation and implementation process.

Organic Farmers

AbstractWeed management is a major concern for organic farmers. Strategies and techniques used by organic farmers vary according to crops, soils, climate and other factors. Organic farmers in upstate New York experienced in weed management were interviewed about what weed–crop complexes they face, how they manage weeds, and what priorities they have for research. The interviews were complemented with an all-day focus group conducted with the farmers who were interviewed. All of the farmers interviewed relied heavily on cultural practices, such as crop rotation, fertility management, high-density planting, transplants and the use of cover crops. Mechanical practices were also important for the farmers interviewed. They emphasized selection of the appropriate tools for the situation and techniques for using tools effectively. Most of the farmers interviewed relied on intensive tillage to control perennial weeds. Differences in practices were notable among the farmers interviewed. Several farmers shared innovations both in practices and equipment modification. Farmers identified soil and nutrient management; tillage and cultivation tools and practices; natural herbicides; flame weeding and no-till systems without herbicides as research priorities. Some of the topics suggested for research have already received substantial research attention; identification of these topics by the farmers indicated a need to disseminate research findings through extension materials and demonstration of viable practices.
