| Dryland agroecosystems are generally ideal environments for recycling biosolids. However, what is the efficacy of biosolids addition to a no-till dryland management agroecosystem? From 2000 to 2010, we studied application of biosolids from the Littleton/Englewood, CO Wastewater Treatment Plant versus commercial nitrogen fertilizer in dryland no-till wheat (Triticum aestivum, L.)-fallow (WF) and wheat-corn (Zea mays, L.)-fallow (WCF) rotations at a site approximately 50 miles east of Denver, CO. We tested if biosolids would produce the same yields and grain phosphorus, zinc, and barium concentrations as an equivalent rate of nitrogen fertilizer, that biosolids-borne phosphorus, zinc, and barium would not migrate below the 4 inch soil depth, and that... |

| Irrigated and dry/and winter wheat is one of the major crops produced in the High Plains of Texas. As reported by the U.S. Census of Agriculture the acreages of irrigated wheat harvested in the High Plains in 1950, 1954, and 1959 were 133,000, 179,000 and 380,000 acres, respectively. Additional irrigated wheat is used only for grazing purposes. The major part of the irrigated winter wheat harvested in the mid-1950's was in Castro, Deaf Smith, Floyd, Hale, Parmer, and Swisher Counties. The soils in these counties consist mostly of clay looms and silty clay loams. Continued expansion in irrigated wheat acreage has occurred since 1959, especially north of the Canadian River. |
