Dual-use systems are still novel, and to a degree experimental. What agricultural activities are most compatible with dual-use is not well understood, nor is whether the new incentive will be sufficient to spur significant adoption of dual-use cropping systems. UMass has important roles in the development and adoption of dual-use systems. First, UMass Extension will serve as a clearinghouse of information and an educational resource for the agricultural and solar energy communities regarding the new technology and new incentive program.

The project addresses how flowering plants achieve fertilization, which if unsuccessful will result in reproductive failure, devastating agricultural productivity. Pollen grains germinate on the stigma, the receptive surface of the female organ pistil. Each pollen grain hydrates and extrudes a pollen tube whose function is to transport two sperm cells carried in its cytoplasm to the female gametophyte inside an ovule, usually located at some distance from the stigma.
We will develop a mathematical model that predicts how farmers (or firms) will make decisions when choosing between two markets. The markets we will study include a wholesale market, where farmer's products are no different from all other farmers, and a farm-to-school market where the farmer's products are differentiated (the farmer is known and the products are known to be locally produced). We will then design economic experiments that could be used to test the model's theoretical results.
Grapes have a high establishment cost of $20-30K/acre and delayed returns during a 3-4 year establishment period. Profitability and sustainability depends upon reliable productivity and resilience to inevitable climate-related injury.
Each potential adopter faces a crucial decision--to lease or to own the panels. Leasing the panels from a solar company incurs little to no upfront cost. A fixed lease payment, however, reduces the net saving from the electricity generated by the panels. On the other hand, owning solar panels includes a high immediate cost with a higher return in future periods resulting from the absence of lease payments. Moreover, solar owners can receive additional revenue from selling Solar Renewable Energy Certificates (SREC).
Municipalities worldwide are showing substantial interest in urban greening, defined here as the introduction or conservation of outdoor vegetation in cities. In many cases greening involves substantial tree planting, and across the United States cities have established ambitious canopy cover goals and major tree planting programs.
Predation is considered a key limiting process, and management actions for declining species, such as forest-dwelling songbirds, are often aimed at reducing impacts of predation. This is of particular concern in areas undergoing urbanization, since densities of potential predators tend to increase dramatically with urbanization.
Plants are an ancient, rich and sustainable source of natural chemodiversity in the form of alkaloids, terpenoids, flavonoids, tannins and other classes of small-molecular-weight compounds (phytochemicals). Lacking the adaptive immunity of animals, plants evolved to rely on small molecules for their survival, proliferation and reproduction.
We have promising proof-of-concept results with a small cohort of mares and would like to conduct further studies withadditional mares to address the safety and efficacy of this approach. This is a proof of concept project that addresses: a)potential harmful endocrine disruptors; and b) dangerous mare behavior patterns associated with estrus that put horse ridersand handlers at risk; and c) the hypothesis that current inadequacies in equine estrus control need to be revisited.
Results from the proposed new NE multistate project will help us to develop an understanding of how vernal pool ecosystems differ across the region in distribution, hydrology, periods of inundation (hydroperiod), redox chemistry, and carbon storage, flux, and accounting. In addition, we will continue our region-wide focus on hydric soils and hydric indicators to determine if there is a need for additional hydric soil indicators for vernal pool ecosystems.
