1. Strategic Tillage Effects on Crop Yield and Soil Properties and Dryland Crop Rotations This study evaluated strategic tillage (ST) to control HR weeds and improve crop yields in an otherwise long-term no-till (NT) soil. Treatments were five crop rotations: 1) continuous winter wheat (Triticum aestivum L.) (WW); 2) wheat-fallow (WF); 3) wheat-sorghum (Sorghum bicolor L.)-fallow (WSF); 4) continuous sorghum (SS); and 5) sorghum-fallow (SF) as main plots. The sub-plot were reduced tillage (RT), continuous NT, and ST of NT. Results showed tillage (ST or RT)... A. Obour, J. Holman, L. Simon, A. Schlegel
2. In-furrow Placement of Dry Urea Prodcuts with Winter Wheat Previous research has shown that the application of some nitrogen fertilizer prior to or at the time of wheat seeding can positively affect the initiation of fall tillers and thus yield potential. However, there are logistical challenges in placing that nitrogen in no-till production systems. Traditionally, the placement of urea-based fertilizers in-furrow with wheat seed has not been recommended. The objectives of this project were to evaluate stand reduction and associated... L.

3. Long-term Forage Rotation Yields, Soil Water Use, and Profitability Forages are important for the region’s livestock industry and are becoming increasingly important as irrigation capacity and grain prices decrease. Forages require less water than grain crops and may allow for increasing cropping system intensification and opportunistic cropping. A study was initiated in 2012 at the Southwest Research-Extension Center near Garden City, KS, comparing several 1-, 3-, and 4-year forage rotations with no-tillage and minimum-tillage. Data presented are from 2013... J. Holman, A. Obour, A. Schlegel, L. Simon Download paper
4. Impact of Fertilizer Phosphorus (P) Source, Rate, and Placement Strategy on Yield, Nutrient Uptake, and P Losses in Snowmelt Runoff Water Across Variable Topographies in Saskatchewan, Canada The plant availability and mobility in soil of a fertilizer phosphorus (P) source is influenced by the solubility of the fertilizer product itself as well as the reaction products formed in soil over time. In 2021, 2022 and 2023, responses of wheat, pea and canola yield, P uptake and recovery were determined using eight fertilizer P sources applied in a broadcast and incorporate or side-band placement strategy at a low and high (20 vs 40 kg P2O5 ha-1) rates in...
