dc.description.abstractIntensive hog operations generate large amounts of manure that must be dealt with in a manner that is both economically and environmentally sound. The objective of the research described is to evaluate the effect of supplemental sulfur (S) fertilizer as means of enhancing crop recovery of liquid swine manure (LSM) nitrogen (N). A long - term swine manure field trial located on a Gray-Black Chernozem with loam texture near Melfort, SK was used in the study. The application of 37,000 L ha-1 LSM supplied approximately 80-100 kg N ha-1, and approximately 7-10 kg S ha-1 in the year of application. Supplemental S fertilizers in the form of elemental S and potassium sulfate were applied at one end of the treatments at a rate of 40 kg ha-1 every three years starting in 2002 and repeated in 2005. Supplemental S fertilizers were evaluated using measurements of seed yield and crop N recovery. Grain N concentration and fall soil N was also investigated. Data obtained in the 2005 and 2006 field season indicate that the low rate LSM of 37,000 L ha-1 supplied sufficient amounts of N and S to maximize seed yield and N recovery. The 80 kg N ha-1 urea treatment showed significant increases in seed yield and crop N recovery with supplemental S fertilizers.en_US
