| A rising concern with the application of dairy wastes to agricultural fields is the accumulation of copper (Cu) in the soil. Copper sulfate (CuSO4) from cattle foot baths are washed out of dairy barns and into wastewater lagoons. The addition of CuSO4 baths has been reported to increase Cu concentration significantly in manure slurry from 4.8 g/1000 L to 88.6 g/1000 L (Miner Institute, New York). The Cu-enriched dairy waste is then applied to agricultural crops, thus raising concerns about how soils and plants are impacted by these Cu additions. |

| A rising concern with the application of dairy wastes to agricultural fields is the accumulation of copper in the soil. Copper sulfate from cattle footbaths is washed out of dairy barns and into wastewater lagoons. Potato growers are concerned about this issue, as many of the predominant dairy producing areas in Southern Idaho are also in Idaho’s established potato production regions. The objective of this project was to evaluate potato growth and copper plant uptake for potatoes grown under low, moderate, and excessively high soil copper concentrations. This study was conducted in 2011 in a greenhouse setting at the USDA ARS Kimberly Research Station. To establish an effective copper response curve, 6 rates of copper sulfate (0, 100, 200, 300, 400, and... |

| Seven grass species--desert wheatgrass (Agropyron desertorum), streambank wheatgrass (Agropyron riparium), cheatgrass (Bromus tectorum), basin wildrye (Elymus cirtereus), Sandberg's bluegrass (Poa sandbergii), bottlebrush squirreltail (Sitanion hystrix), and needle-and-thread grass (Stipa comata)--were harvested to a 1/2-inch (1.2-cm) stubble height periodically between mid-March and December in most years from 1962 through 1968 at the Saylor Creek Experimental Range in southern Idaho. These samples were analyzed for N, P, S, Ca, Mg, K, Na, Zn, Mn, Cu, and Fe. Certain digestibility fractions (NDF, NDF-ash, DCW, DCW-ash free, and TDDM) were also determined on these samples. In addition, estimates of the soil chemical status, soil moisture contents... |

| 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. |
