  • Long-term effects of tillage, nitrogen, and rainfall on winter wheat yields

    Creator:
    Camara, Kelli Marie
    Abstract:
    Winter wheat is commonly grown in dryland cropping systems in the Pacific Northwest region of semi-arid eastern Oregon. For agronomic, economic, and environmental reasons, it is important to understand the long-term sustainability of such dryland systems. The objective of this study was to evaluate the long-term effects of tillage, nitrogen...

  • Soil quality dynamics in an integrated reduced-tillage and cover-cropped vegetable agroecosystem

    Creator:
    Banners, Candace R.
    Abstract:
    Soil response and function were investigated following the adoption of an integrated reduced-tillage and cover-cropped vegetable system in the Willamette Valley of Western Oregon. The experiment was conducted over three cropping seasons (2002-2004) at the Oregon State University Vegetable Research Farm (Corvallis, OR). The design was a randomized complete-block with...
