Vigorously growing plants require adequate, but not excessive, essential nutrients. Nutrients must be provided in the right form, at the right time, and at the right place. Management of all nutrients sources (i.e., soil, commercial fertilizer, compost, and animal and green manure) within the constraints of the production system is fundamental to both economic viability and environmental quality. Poor management of plant nutrients can lead to economic losses and environmental degradation of soil, air, and water quality.
There is uncertainty about the effects of future climate on agricultural crop plants. Alfalfa is a crop that is used to provide feed for animals leading to meat production. This research will include experiments under controlled conditions that will allow prediction of how alfalfa plants will respond to future elevated CO2 (800ppm) and elevated ozone (O3) (80ppb). How these elevations affect plant growth and the nutritional value of the plants will be determined.
Increased use of biomass fuels is a promising option for renewable fuels that could decrease our dependence on oil and reduce greenhouse gases. Unfortunately, we currently do not have clear knowledge about the plant traits that should be considered bioenergy traits and should be subjected to breeding and selection. We propose to use a grass energy model organism (Brachypodium distachyon), and treatment with two promising plant biomass transformation techniques (biological and thermochemical conversion) to examine the effect of natural diversity on biofuel production efficiency.
The cranberry industry in Massachusetts faces many challenges. In the past ten years, growers have gone from receiving record high prices for their fruit to record low prices. Although the industry has rebounded, the focus to remain economically competitive and environmentally sustainable has sharpened. It is anticipated that the industry may lose some acreage due to attrition and that smaller growers may sell their land. As with all farmers, energy costs are rising quickly, impacting the bottom line. Growers must develop and adopt innovative technology to remain competitive.
Fruit farms and vineyards provide open space and scenic vistas that add significantly to the quality of life in Massachusetts. The lands surrounding agricultural production provide buffer zones for native species of plants and animals and corridors for their movement or expansion. To remain a vital part of the Massachusetts economy, both new and established growers must learn to produce crops sustainably and to adapt production systems to market opportunities. New varieties provide fruit farmers with opportunities for enhancing production, quality, sales and consumption.
During bloom, pesticide use pattern is changing rapidly in many crops owing to phase-outs of some chemistries and introduction of new ones. In cranberry, two new fungicides now dominate applications of choice during bloom; the recommendation is to use the two modes of action simultaneously to slow evolution of resistance by fungal pest species. In order to save time and money, growers frequently add an insecticide simultaneously to the fungicide mix in order to manage the key pest, cranberry fruitworm. Alone, all of the compounds are considered 'bee safe' and bloom sprays are allowed.
The Extension Vegetable Management Team team have engaged new stakeholders, revitalized our applied research program, and responded to regulatory changes impacting stakeholders. We have been successful in garnering external funds to support the expansion of this project and the scope of our efforts to address stakeholder needs.

Improving water management is of increasing importance in horticultural operations. A growing global population and changes in water availability will mean that less water will be available for ornamental plant production. There are also a growing number of federal and state regulations regarding water use and runoff from production areas. Better irrigation and fertilization management practices will help to limit the environmental impact of container plant production by limiting the runoff of water and nutrients from nurseries.
