Missouri researchers study golf course grass to address agricultural challenges
One billion hectares of land, an area about the size of the U.S., are affected by salty soil, according to the Food and Agricultural Organization of the United Nations. The majority of crops are sensitive to salt, resulting in production declines that cost at least $27 billion each year, says a study published by the United Nations. “And it’s continually getting worse,” said David Goad, a doctoral candidate at Washington University. As agricultural fields are irrigated, water evaporates but salt doesn’t, producing saltier soils each year. These issues are particularly problematic in dry, hot climates, including the western U.S.
