Applying dairy manure to agricultural fields has been shown to increase crop yields, improve the water-holding capacity of the soil, and enhance soil fertility. However, when manures are applied to fields at high rates over a period of several years, nutrients can accumulate, causing eutrophication in drainage waterways; degradation of drinking water; nutrient toxicities in plants; nutrient deficiencies in plants; disruptions in soil microbial populations; and nutritional imbalances for grazing animals. Growersand dairy producers also run the risk of violating state and federal regulations designed toavoid these issues. |

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... |

Decomposition rates directly affect carbon and nitrogen ratios, which can affect nitrogen mineralization rates. The objective of this research is to determine the effect of tillage method and nitrogen rate on nitrogen available to sugar beets planted after a cereal crop. This two-year field study conducted in Kimberly, Idaho, consisted of three tillage methods (moldboard plow, chisel plow, and strip tillage), two tillage timings (fall and spring), and four fertilizer N rates plus a control. Soils from each plot were sampled shortly after nitrogen fertilization and incubated at average seasonal temperatures for Kimberly, Idaho to monitor nitrogen mineralization patterns. In 2008, we found that at N fertilizer rates of 0, 50, and 100 lbs N per acre,... |

A rising concern with the application of dairy wastes to agricultural fields is the accumulation of copper in the soil. Copper sulfate from cattle footbaths is washed out of dairy barns and into wastewater lagoons. Potato growers are concerned about this issue, as many of the predominant dairy producing areas in Southern Idaho are also in Idaho’s established potato production regions. The objective of this project was to evaluate potato growth and copper plant uptake for potatoes grown under low, moderate, and excessively high soil copper concentrations. This study was conducted in 2011 in a greenhouse setting at the USDA ARS Kimberly Research Station. To establish an effective copper response curve, 6 rates of copper sulfate (0, 100, 200, 300, 400, and... |

The sugarbeet (Beta vulgaris L.) industry in Idaho is interested in strip tillage (ST) primarily due to the potential savings in tillage costs. This study was conducted to evaluate the use of strip tillage in Idaho compared to conventional tillage practices and to evaluate N requirements of sugarbeet under ST and conventional tillage. The effect of tillage method (strip tillage, moldboard plow system [MP], and chisel plow system [CP]) and N supply (5 levels) on sugarbeet production factors were investigated in Kimberly, ID from 2008 to 2010 on a Portneuf silt loam with barley as the previous crop. Root and estimated recoverable sucrose (ERS) yields were the same under all three tillage practices. However, estimated tillage costs for ST were from 53... |

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,... |
