Sheep (Ovis aries L.) grazing, an effective method of controlling weeds and pests in a wheat (Triticum aestivum L.)–fallow system, may affect dryland soil properties and wheat yield. We evaluated the effects of fallow management for weed control and soil water conservation (sheep grazing, herbicide application [chemical], and tillage [mechanical]) and cropping sequence (continuous spring wheat [CSW], spring wheat–fallow [SW-F], and winter wheat–fallow [WW-F]) on soil nutrients and chemical properties in the 0- to 60-cm depth and wheat yield. The experiment was conducted in a Blackmore silt loam from 2004 to 2008 in southwestern Montana. Soil P and K concentrations …
