Relative agronomic efficiency (RAE) of phosphorus (P) in nutrient-rich residues with different chemical characteristics must be known order to optimize their use as fertilizers, avoid underfertilization crops or eutrophication surface waters due overfertilization. In this study, we determined the and RAE manures (cattle, pig, fox) sewage sludges subjected treatments (anaerobic digestion, compos...

A major cash crop in the Bighorn Basin of Wyoming (WY) and Yellowstone River valley eastern Montana (MT) is Sugarbeet (Beta vulgaris L.). This growing area characterized by alkaline/calcareous soil conditions that inhibit phosphorus (P) availability. Phosphorus, however, reported to increase root growth sugarbeet. study evaluated effects two P fertilizer sources rates on sugarbeet productivity ...
