Incorporating economics into the phosphorus index: an application to U.S. watersheds.(Research)
Sep 01, 2003; ... ********** Phosphorus is an essential macronutrient for crop and livestock production. However, applications of commercial and manure phosphorus on cropland often exceed crop uptake requirements (National Research Council, 1993; Heathwaite et al., 2000; Kellogg et al., 1997), ...
Nutrient removal by grass components of vegetated buffer systems receiving swine lagoon effluent.(Research)
