<b>Data from Dryland Cropping System Studies at the Northern Great Plains Research Laboratory, 2006-2009</b>

Dryland cropping systems in the northern Great Plains are challenged by erratic and limited water availability, persistent wind and water erosion, and reduced soil fertility. Long-term experiments evaluating novel innovations can provide insights to help producers overcome these challenges. Multiple studies were conducted to evaluate crop yield and soil properties in three cropping system treatments established in 1994 in central North Dakota USA. Cropping systems included spring wheat (<i>Triticum aestivum</i> L.) – fallow, continuous spring wheat, and spring wheat – safflower (<i>Carthamus tinctorius</i> L.) – rye (<i>Secale cereale</i> L.). Cropping systems were managed using no-tillage practices. Measurements of crop yield, soil properties and processes, and weather metrics were collected following established protocols from 2006 through 2009. Data may be used to investigate crop and soil responses to dryland cropping systems in a semiarid continental climate. Applicable USDA soil types include Temvik, Wilton, Grassna, Linton, Mandan, and Williams.
