| Funding is being sought from multiple sources to update nitrogen fertilizer recommendations for irrigated corn in southern Idaho and southwest Oregon. This paper summarizes the justifications and main objectives of this proposed research. Nitrogen needs to be correctly managed in corn production systems to optimize economic returns and to protect the environment. The fertilizer nitrogen recommendations for irrigated field corn in Idaho and other parts of the Pacific need to be re-evaluated because: (1) University of Idaho (U of I) and PNW region recommendations are based on sparse research data; (2) Recommendation are based on research data that is over 25 years old; (3) Corn production area and yield have increased dramatically in concentrated areas due... |

| Growers working with manured soils o� en rely on soil test information when developing nutrient management for their crop, especially when manure application information is unavailable. Nutrient-enriched soils, like manured soils, can trigger nutrient de� ciencies and toxicities due to plant–soil nutrient interactions. � e goal of the study was to determine correlations between soil test and plant tissue nutrient concentrations for irrigated corn silage crops (Zea mays L. subsp. mays) with varying nutrient concentrations unique to dairy manure-enriched calcareous soils. Whole plant and soil samples were collected from 39 cooperator corn silage � elds at harvest over a 2-yr period throughout the Snake River Plain region of southern Idaho. Soils were... |

| 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,... |
