U.S. Department of Agriculture (USDA) scientists have developed a new way to determine the moisture content of grain stored in bags, a main storage option in underdeveloped countries in Africa. Together with Kansas State University colleagues, Paul Armstrong, an agricultural engineer with USDA's Agricultural Research Service (ARS) in Manhattan, Kansas, has developed a hand-held meter that measures the relative humidity and temperature of the air within the grain, two key parameters used to estimate moisture content. The Post-Harvest Loss (PHL) moisture meter is easily made with "off-the-shelf" parts for about $75.
