Songbird-Mediated Insect Pest Control In Low Intensity New England Agriculture, Samuel J. Mayne
Songbird-Mediated Insect Pest Control In Low Intensity New England Agriculture, Samuel J. Mayne
Masters Theses
Global agricultural intensification has caused large-scale wildlife declines, but agricultural lands that maintain natural habitats can support healthy wildlife populations and receive significant ecosystem services from these natural communities. However, how on-farm biodiversity results in beneficial ecosystem services is highly variable and is reported to differ among taxa and guilds. One group that has attracted attention for their potential beneficial role in reducing pest abundance are birds. Understanding the role of bird communities and individual species in pest control could be important for managing farms under a low intensity agroecological framework. In New England, farmers are increasingly applying low intensity …
Assesment Of Ammonia Volatility From Fall Surface-Applied Liquid Dairy Manure, Katie Campbell-Nelson
Assesment Of Ammonia Volatility From Fall Surface-Applied Liquid Dairy Manure, Katie Campbell-Nelson
Masters Theses 1911 - February 2014
Ammonia emissions from dairy and livestock operations are of significant environmental and human health concern in the United States. Conservation of ammonia from fall surface-applied manure could benefit farmers by retaining nitrogen for use by crops in the spring growing season. The primary goal of this research was to investigate a management strategy for mitigating ammonia volatility from cow manure at the time of field application with no incorporation in the fall before snow fall. The hypothesis is that application of manure in cooler fall temperatures will slow the rate of ammonia volatilization. The objective was achieved by measuring temperature …
