1. OVERVIEW

USDA’s Genetic Improvements for Fruits and Vegetables Laboratory (GIFVL) at Presque Isle is a Substation of the Beltsville Agricultural Research Station, 10300 Baltimore Avenue, Beltsville, DM 20705. GIFVL grows their potato crop and maintains a potato storage barn at the Chapman Farm located at 980 Carvell Road, Chapman, ME 04757.

Research conducted at the farm examines ecologically based, biologically efficient, and economically profitable management systems of an agricultural commodity. Research activities include the development and testing of new potato varieties and investigations on the effects of cultural practices on potato growth, development, yield, and quality. To help with the problem of diseases of potatoes, scientists are investigating the molecular genetics of potato pathogens, developing new, faster methods to detect potato viruses in seed stock, and working to develop more disease-resistant potato varieties. Scientists also have investigated effects of soil amendments and crop rotation on soil properties and potato productivity and looking at how the use of manure and yard waste affects the soil.

Insulation is a key factor for a potato storage building, much more so than it is for general purpose buildings. The quality of the insulation will determine to a large extent how well a potato store performs. A well-sealed and insulated potato storage building will allow the crop to be kept at a stable temperature largely unaffected by diurnal (daily) variation in ambient conditions. It will help maintain a relative humidity of 90–100 per cent to minimize tuber weight loss; it will also allow crops to be stored free from condensation in changeable weather conditions.

Controlled ventilation allows crop respiration heat to be removed and a crop to be dried and cooled. Fans are best positioned to create a flow of air through the crop or, less efficiently, to form a rolling mass of air that flows over the stack of boxes and through the pallet slots (space ventilation).

Building leakage to wind-induced ventilation reduces the effectiveness of the storage, as it is likely to lead to loss of environmental control. Crop weight loss and possible condensation on the crop will result and ventilation or refrigeration running hours will increase, in order to cool the crop warmed by the leaking air.

2. PROJECT REQUIREMENTS:

2.1. POTATO STORAGE BUILDING (Building 1300B000003): The Potato Storage Building is a 40’x62’ (2,480 SF) metal barn, which is 14 ft high at the perimeter walls and 16 ft high at the ridge that was constructed in 1968.
