Interpretive Summary:

Technical Abstract: Winter wheat pasture provide high-quality forage for grazing livestock. Winter wheat is grown as a dual-purpose crop offers a unique opportunity to have benefits of grain production and weight gain by beef cattle pastured on winter wheat crop up to joint growth stage. In addition, beef cattle integration may influence soil characteristics. In this study, we present short-term (after one growing cycle) soil characteristic dynamics in beef cattle pastured (WGR)/un-pastured (W) winter wheat double-cropped with soybean as the summer crop. Soil P, K, Cu, and Zn contents did not change in the two systems [(P-W: 30.8-29.7; P-WGR: 25.5 -29.7mgkg-1), (K-W: 279-281.8; K-WGR: 196-237.6 mgkg-1), (Cu-W: 2.7-1.9 ; Cu-WGR: 2.7-2.0 mgkg-1), (Zn-W: 4.7-4.6 ; Zn-WGR:4.1-4.6 mgkg-1)]. Total soil C (TC), N (TN), and NO3-N contents increased in the two systems [(TC-W: 22.1-30.9; TC-WGR: 17.6-28.3 gkg-1), (TN-W: 2.3-2.9; TN-WGR; 1.9-2.8 gkg-1), (NO3-N-W; 3.3-9.4; NO3-N-WGR-: 4.0-8.7 gkg-1)]. The NH4-N contents decreased in both pastured and un-pastured systems (W-NH4-N: 18.2-12.8; WGR-NH4-N: 19.7-10.6 gkg-1).
