| Corn silage is the predominant crop in Idaho used for recovering phosphorus (P) that has accumulated in soils from dairy manure applications. However, little is known about how much P and other nutrients are being recov- ered under Idaho conditions. The objective of the study is to estimate P removal by irrigated corn silage crops cultivated throughout southern Idaho with variable soil test P concentrations, and to identify effects of increasing soil test P on tissue concentrations of P and on plant P uptake. Forty-two different corn silage fields in 2008 and 2009 were selected throughout southern Idaho for soil and whole plant sampling at harvest. Soils were ana- lyzed for Olsen P, plant tissue was measured for total P content,... |
