Manure Application Improves Health of Arid Texas Soils

Texas researchers explored how applications of cattle manure could help improve the health of arid Texas soils, reports the American Society of Agronomy. This research project involved a one-time application of a low level of manure to grassland pastures. The manure helped increase soil organic carbon and the number of microbes in the soil, but the changes took nearly 18 months due to the dry climate. The researchers plan to explore whether more manure or multiple applications would get faster results and if irrigation or addition of nitrogen fertilizer would help incorporate the manure faster.
