  • Effects of tillage systems on nitrate-nitrogen accumulation and soil structure

    Creator:
    Avcin, Abdulkadir
    Abstract:
    Effects of different tillage systems on nitrate-nitrogen accumulation in a 120 cm profile and on soil structure in the top 30 cm of the profile were studied under a fallow-wheat rotation. Treatment effects on nitrate-nitrogen, soil moisture and soil aggregation were measured. Fallow tillage treatments consisting of bare fallow, stubble-mulch...

    Abstract:
    No-tillage winter wheat (Triticum aestivum L.) grown in a wheat-fallow cropping system has consistently produced lower grain yields than conventionally tilled soils in the semiarid Pacific Northwest. A 2-year study was conducted in a long-term tillage trial at Moro, OR to determine factors responsible for differences in wheat growth and...
