| Twenty crossbred barrows weighing 35.8±3.1 kg, were fed 1 of 5 diets (N = 4) to determine the effects of different cereal grains on fecal P excretion and composition. The diets contained 97.15% corn, wheat, high fat-low lignin oat, normal barley or low phytate barley with the cereal grain supplying the sole source of dietary phosphorus. The diets were fed for a 7 day acclimation period followed by a three-day fecal collection. Total tract digestibility coefficients were determined for dry matter, phosphorus and phytate using the indicator method. Fecal phosphorus was characterized using solution state Phosphorus Nuclear Magnetic Resonance spectroscopy (31P-NMR). Water Soluble Phosphorus (WSP) and the ratio of WSP to total phosphorus (WSP:TP) were... |

| Rhizomania caused by Beet necrotic yellow vein virus (BNYVV) and storage losses are serious sugar beet production problems. To identify sugar beet cultivars with resistance to BNYVV and evaluate storability, 31 commercial cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2011 growing season in a randomized complete block design with 4 replications. At harvest on 18 October 2011, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building. Storage samples were evaluated for fungal growth known to correlate with sucrose loss. Depending on cultivar, surface root discoloration (rot and fungal growth)... |

| Recent efforts to reduce phosphorus (P) content of corn grain fed to poultry have led to the development of low-phytic-acid corn. Research is needed to evaluate the environmental impact of the application to cropland of manure from animals fed low-phytic-acid corn. The purpose of this research was to determine P losses in runoff from a bare Piedmont soil (cecil clay loam; clayey, kaolinitic, thermic, Typic Kanhapludult) in the southeastern United States receiving surface applications of broiler litter from birds fed a low-phytic-acid corn (HAP broiler litter). The HAP litter was applied at rates of 0, 8, 16, 33, 49, 66, and 82 kg P ha-1 . Simulated rainfall was applied at a rate of 7.6 cm hr-1 on the same day the litter sources were applied to... |

| Plant analysis historic beginnings are generally attributed to T. de Saussure (1804) following studies by van Helmont, Joseph Priestly, Henry Cavenish, and Antonine Lavoisier. de Saussure showed that the composition of plant ash varied with the part analyzed, with the age of the plant, and with the soil upon which the plant grew. The ash was chiefly composed of alkalis and phosphates. Erasmus Darwin in his 1800 book, Phytogia: The Philosophy of Agriculture and Gardening (London, J. Johnson) wrote that both nitrogen (N) and phosphorus (P) were essential components of plants. In 1833, the Fifth Duke of Richmond showed that the value of bone meal fertilizing was due to its P component rather than calcium (Ca), although Justus von Liebig (1852) is... |

| Controlling sucrose loss in sugarbeet storage has been an industry goal since the 1950s. Sugarbeet roots utilize sucrose for energy to maintain themselves. Dessication from wind and sun or too much rain and microbial activity can negatively influence stored roots, increasing respiration and the buildup of impurities. Factors such as scalping, impacts and wounding during harvest and transport, mud and weeds in piles, and unusually high and low temperature can also lead to sucrose loss. Disease and drought stress during production can also predispose roots to sucrose loss in storage. In particular, rhizomania caused by Beet necrotic yellow vein virus has been shown to compromise the storability of roots allowing for significant sucrose... |
