  • End-of-season corn stalk nitrate-nitrogen test for post-harvest evaluation : a case study 

    Tao, Haiying; Pan, William L. (Pullman, Washington : Washington State University Extension, 2019-11)
    Land application of dairy manure to cornfields is a common practice and a major method of manure disposal for dairy operations. Dairy manure provides numerous benefits for corn and other silage crops. However, excess ...
  • Establishing vegetative filter strip on rill-irrigated row fields 

    Bodah, Brian W.; Ullman, Jeffrey L.; Stannard, Mark; Peters, R. Troy; Pan, William L. (Pullman, Washington : Washington State University. Extension., 2016-04)
    The establishment of vegetative filter strips (VFSs) on the ends of rill- or furrow-irrigated crop fields has proven to be an effective best management practice (BMP) to lower the suspended sediment and soluble nutrient ...
  • Forage productivity of vegetative filter strips established on rill-irrigated row crop fields 

    Bodah, Brian W.; Connolly, Jennifer R.; Ullman, Jeffrey L.; Stannard, Mark; Peters, R. Troy; McCracken, Vicki; Pan, William L. (Pullman, Washington : Washington State University. Extension., 2016-04)
    Vegetative filter strips (VFSs) are a best management practice (BMP) consisting of planted areas that remove pollutants from surface water runoff. These systems are traditionally implemented along streams and rivers (referred ...
  • Managing and maintaining vegetative filter strips on rill-irrigated row fields 

    Bodah, Brian W.; Ullman, Jeffrey L.; Stannard, Mark; Peters, R. Troy; Pan, William L. (Pullman, Washington : Washington State University. Extension., 2016-04)
    This portion of the WSU Extension series on Vegetative filter strips (VFSs) describes management considerations for maintaining an effective VFS that mitigates off-field movement of contaminants and does not impede ...
  • Nutrient Management Guide: Central Washington Irrigated Potatoes 

    Lang, N. S.; Stevens, Robert G.; Thornton, Robert Earl, 1933-; Pan, William L.; Victory, S. (Pullman, Washington : Washington State University. Extension., 1999-03)
    The amount of fertilizer recommended in this guide is the amount needed to produce optimum yield of the current potato crop. Discusses potato nitrogen needs, phosphorus, potassium and sulfur, plus additional nutrients. 8 pages.
  • Phosphorus Fertilizer: Broadcast Banding and Starter 

    Pan, William L.; Engle, Carl F. (Pullman, Washington : Washington State University. Extension., 1991-11)
    This bulletin discusses phosphorus fertilization of crops, including broadcast, band, and starter applications, salt damage, cold soils, and germination damage. Crops mentioned are small grains, peas and lentils, and ...
  • Physiology matters : adjusting wheat-based management strategies for oilseed production 

    Beard, Taylor L.; Sowers, Karen; Pan, William L. (Pullman, Washington : Washington State University. Extension., 2016-10)
    The wheat-dominated inland Pacific Northwest (iPNW) has a broad range of environments and soil types; however, the region lacks crop diversity. Many other semi-arid wheatgrowing regions throughout the world have successfully ...

    Lang, N. S.; Stevens, Robert G.; Thornton, Robert Earl, 1933-; Pan, William L.; Victory, S. (Pullman, Washington : Washington State University. Extension., 1999-02)
    This management guide summarizes nutrient management concepts for maintaining high potato yields, while minimizing environmental impact. Topics include: potato growth stages and nutrient demand, soil and plant sampling, ...
  • Vegetative filter strip use as a rill-irrigated best management practice 

    Bodah, Brian W.; Ullman, Jeffrey L.; Stannard, Mark; Peters, R. Troy; Pan, William L. (Pullman, Washington : Washington State University. Extension., 2016-04)
    Best management practices (BMPs) are a series of guidelines and that help farmers reduce the impact that farming has on the local environment by limiting the amount of aquatic pollution that comes from farms. A vegetative ...
  • Vegetative filter strips as a best management practice on rill-irrigated row fields 

    Bodah, Brian W.; Ullman, Jeffrey L.; Stannard, Mark; Peters, R. Troy; Pan, William L. (Pullman, Washington : Washington State University. Extension., 2016-04)
