Abstract
  • The potential of mechanically applied straw mulch to reduce nutrient, pesticide and sediment losses from furrow irrigated onions and increase water use efficiency was evaluated on a Nyssa silt loam with three percent slope. Nitrogen and phosphorus losses in the runoff were of particular interest, both because of their economic importance as farm inputs and their roles as environmental contaminants. Measured losses of phosphorus included phosphate-P dissolved in runoff water, phosphate-P present in the sediment, and total P in the sediment. Measured nitrogen losses included ammonium and nitrate in runoff and on the sediment and total reduced N in the sediment.
