1. Manure Treatments Change Nitrogen Cycling in Soils Receiving Repeated Applications of Dairy-wastesOur objective was to assess effects of treated dairy-waste on soil N pools, nitrification, plant N availability, and yield in a silage cornfield treated with ammonium sulfate (AS), dairy-waste compost (DC) or liquid dairy-waste (LW) as N sources at two levels of application over 5 years. Increases in soil C and N, nitrate and available P and K were observed for the DC treated soils throughout the 5-year period. Soil organic C increases for the high-level DC treated soil doubled the C pool resulting... J. Norton, M. Habteselassie, J. Stark, B. Miller |
2. Sus-Terra Enhanced Efficiency Phosphorus Fertilizer on Potato Grown in Calcareous SoilPotato (Solanum tuberosum L.) has a relatively high demand for phosphorus (P), especially on calcareous soil where the availability of P in hindered by poor solubility. Sus-Terra is claimed to be an enhanced efficiency fertilizer compared to other P sources. The objective of this trial was to evaluate the differences in uptake efficiency and yield for multiple P sources compared to a no P control applied to Russet Burbank potato. Field trials with six replications in a RCBD were... L.K. Sannar, B.G. Hopkins, T.J. Hopkins |
