YUMA, Ariz. (KYMA, KECY) — Researchers at the University of Arizona are testing a heat-loving summer crop that could help improve soil health and water efficiency for future desert farming. Researchers at the University of Arizona Yuma Agricultural Center are studying whether the plant can improve growing conditions for crops commonly grown in the region. “The intent of the planting is to improve the soil health, adding organic matter, carbon, and nitrogen,” a researcher said. The study is comparing Sesbania with more traditional summer crops, including Sudan grass, to determine how each affects soil health and water use. Once the summer portion of the study is complete, researchers plan to plant iceberg lettuce in the test fields.
