Annual cropping is often possible where annual precipitation exceeds 14 inches. It is recommended on soils less than 4 ft deep since the soil profile normally is filled by a single winter's rainfall. Rotation of winter wheat with a spring cereal is often preferred to continuous winter wheat because weed control is easier and stubble more manageable. Fertilizer needs increase sharply under annual cropping because nutrient buildup by fallowing is eliminated and competition for nutrients by residue-decomposing organisms is more intense. In this study, nitrogen, phosphorous and sulfur response by spring barley was determined for annual-crop conventional and minimum tillage.
