Rangelands are an important grazing resource worldwide, but in many regions, supplemental forage is needed to support during parts of the year. Mountain irrigated hay meadows integral hay-producing component livestock operations Intermountain Western United States (US), productive capacity made challenging by short growing season (elevation >2000 m) and inefficient flood irrigation strategies. Further, these factors have reduced residue decomposition led development organic horizon at soil...
Abstract Soil-applied herbicides are important for controlling weeds in many crops but risk damage to susceptible rotational if they persist. Field studies were conducted Powell, WY, from 2015 through 2017 evaluate the effect of reduced water availability on soil-applied herbicide dissipation. Eight herbicides, applied dry bean or corn, exposed three season-long irrigation treatments (100%, 85%, and 70% estimated crop evapotranspiration [ETc]) by overhead sprinkler. Soil samples collected a...
