Storing sugarbeets, in piles, under ambient con- ditions, in production areas with mild climates, allows for longer and more productive factory campaigns. In southern Idaho, approximately one-third of the roots are directly processed, one-third are held in short-term storage, and one-third are held in long-term storage (greater than 90 days). Some beets in long-term storage will be held up to 150 days, leaving roots sus- ceptible to a number of negative influences. Extreme temperature fluctuations, excessive moisture, restricted air flow (snow, soil, weeds, and rotted roots), microbial development, res- piration rate, and buildup of impurities can all negatively impact sucrose recovery. In addition to disease and water-related problems... |

The kinetic energy of discrete water drops impacting a bare soil surface generally leads to a drastic reduction in water infiltration rate due to formation of a seal on the soil surface. Under center-pivot sprinkler irrigation, kinetic energy transferred to the soil prior to crop canopy development can have a substantial effect on seasonal runoff and soil erosion, especially when the soil is not protected by crop residue cover. Droplet kinetic energy of seven commercial off-center action rotating spray-plate sprinklers was characterized over a range of flow rates and pressures. Sprinkler droplet kinetic energy was characterized using two methods; droplet kinetic energy per unit sprinkler discharge and droplet kinetic energy applied per unit water depth... |

National concern about nitrate contamination of groundwater is raisin g many questions about the use of nitrogen fertilizer to grow high-quality crops. Some extremists are suggesting that commercial inorganic nitrogen fertilization should not be permitted. Such a limitation would seriously reduce crop productivity and farming profitability. We hope that it does not occur. However, the farming industry has become somewhat careless in nitrogen management because nitrogen fertilizer has been relatively cheap for the past couple of decades. Commonly, "a little extra nitrogen" has been applied to assure against a deficiency and less than maximum yield. in recent years. sugar beet growers have learned that such a practice can be costly because high... |

Nitrogen (N) excreted in urine by dairy cows can be potentially transformed to ammonia (NH3) and emitted to the atmosphere. Dairy production contributes to NH3 emission, which can create human respiratory problems and odor issues, reduces manure quality, and is an indirect source of nitrous oxide (N2O). The objective of this study was to (i) investigate environmental factors and measurement method that influence NH3 from dairy housing, and (ii) identify key explanatory variables in the prediction of NH3 emissions from dairy barns using a meta-analytical approach. Data from 25 studies were used for the preliminary analysis and data from 10 studies reporting 87 treatment means were used for the meta-analysis. Season, flooring type, manure handling and... |

This overview will be familiar to anyone who has visited the "PAM page" of the Northwest Irrigation and Soils Research Laboratory's web site. The reader is encouraged to visit that web site, <http://kimberlv.ars.usda.qov/ pampaqe.shtml>, for graphics and photos that were used in this NAICC presentation in Orlando in January, 2001, as well as for other more detailed technical information. PAM has been sold in the United States since 1995 for reducing irrigation-induced erosion and enhancing infiltration. Its soil stabilizing and flocculating properties have also substantially improved runoff water quality by reducing sediments, N, ortho and total P, COD, pesticides, weed seeds, and microorganisms in runoff. The first series of practical field... |

Sugar beet root rots are not only a concern because of reduced yields, but can also be associated with losses in storage. Our primary sugar beet root rot disease problem in the Amalgamated production area is Rhizoctonia root rot. However, this rot frequently only penetrates a short distance past the surface of the root before a bacterial complex stops the fungus and continues the rot process. This rot complex leads to direct yield loss at harvest time along with additional costs in factory processing. When rotted roots make it into storage piles, they have been shown to compromise surrounding healthy roots. A recent end-of-harvest storage pile survey of 74 to 76% of the piles at receiving stations in Treasure Valley and Magic Valley has identified... |
