A study was conducted in order to investigate the incorporation of dehumidification into the curing cycle of flue-cured tobacco. Tobacco from the same source and stalk position was cured in a barn coupled to a heat-pump-dehumidifier and, for comparison, in a conventional barn heated with an open flame propane furnace. A procedure for curing with dehumidification was developed. Dehumidification was found to automatically raise temperature and reduce humidity, causing a set in lamina color. Tobacco cured in the heat-pump barn was found to have at least comparable quality with that cured in the conventional barn as determined by standard chemical analyses and USDA grade.

Arsenic in Your Water
Arsenic in your drinking water poses a threat to your health. Since private systems are more susceptible to arsenic than public water systems, private well owners should take steps to guard their health. Measures include routine water supply testing and wellhead maintenance and protection.

Selecting a qualified irrigation contractor is very important. There are many irrigation products available and the installation process requires skill, knowledge and equipment. This publication outlines general considerations for purchasers of a landscape irrigation system. It also underscores the importance of considering the cost of water when selecting a contractor and protecting desirable trees during the installation process.

Frost protection systems tremendously benefit commercial blueberry production in Georgia. These systems are expensive and usually configured as overhead irrigation systems. For the system to provide protection, it must operate as soon as it’s needed. The best practice for maintaining a frost protection system is to perform preventative maintenance service every late fall or early winter. This publication offers blueberry growers suggestions on how to prepare their frost protection systems for future operation. Recommendations include a check-off list for maintenance and inspection of overhead irrigation systems, important considerations when preparing for freeze events.

Nitrate and Nitrite in Water
Private well owners are responsible for the safety of their drinking water. Maintaining a healthy well requires routine testing for possible contaminants, including nitrate and nitrite. To assist in water safety, the EPA has set standards for nitrate levels in public drinking water systems. Although private well owners are not required to meet these standards, they do serve as a reference for safe drinking water. The EPA Maximum Contaminant Level (MCL) nitrate is: 10 ppm (parts per million) or mg/L (milligrams per liter) nitrate-nitrogen or, if expressed as nitrate, 45 ppm. For nitrite, the MCL is: 1 ppm or mg/L nitrite-nitrogen or, 3.28 ppm if expressed as nitrite. Nitrite is not stable in water and rapidly transforms to nitrate fairly easy. Its presence is an indicator of high concentrations of either nitrate or ammonia.
