ENERGY SERIES: What about the Air Conditioning System?
As you begin the process of selecting the most efficient air conditioning system for your home, investigate the critical issues of system size, placement, installation, and contractor experience. Your goal is to obtain an efficient system by: sizing the system for the specific cooling load of your home; selecting and properly installing the thermostats or controls; designing a ductwork system to deliver the correct amount of conditioned air to each space; and sealing and insulating all ductwork.

Droplet Chart / Selection Guide
When choosing nozzles/droplet sizes for spray applications, applicators must consider both coverage needed and drift potential. As a rule, smaller droplets provide better coverage, but larger droplets are less likely to drift.

Using Groundwater for Agricultural Irrigation in Virginia
Virginia usually receives ample rainfall to support agriculture, but droughts in 2002, 2007, and 2010 led to severe problems for farms in many regions. Using groundwater for irrigation can help manage drought risks on farms without access to ponds or streams. However, installing groundwater wells can be expensive and time-consuming. The amount of water obtained from wells can vary in different regions of the state. This bulletin is intended to provide agricultural producers with information on technical and regulatory issues related to irrigating with groundwater.

Managing Drainage From Agricultural Lands with Denitrifying Bioreactors in the Mid-Atlantic
This publication highlights recent advances in adapting denitrifying bioreactors developed in the Midwest to the Mid-Atlantic region. Denitrifying bioreactors are edge-of-field management practices that harness the activity of soil bacteria to remove excess nitrogen from drainage waters. Agricultural drainage is a significant source of nutrients to the Chesapeake Bay and important to manage. Although challenges remain with respect to adapting designs to treat ditch drainage, denitrifying bioreactors hold promise to yield water quality improvements in the Chesapeake Bay watershed.

Estimating Financial Costs and Benefits of Supplemental Irrigation with the Irrigation Financial Estimator Tool (IFET)
Row crop agriculture in Virginia and other Eastern states is largely rainfed, but there is increasing interest in irrigation as a way to manage dry periods and weather variability. However, irrigation systems require substantial installation and operating costs, and it can be very difficult to determine if yield improvements will be sufficient to justify these costs. This publication provides an overview on the Irrigation Financial Estimator Tool, which was recently developed to help row crop producers estimate financial aspects of supplemental irrigation. The tool estimates installation and operating costs, as well as revenues from improved yields, using user-supplied information and historic data on weather and prices for crops and fuel. It accounts for uncertainty in these estimates by presenting a range of values for each cost.
