1. Starter Fertilizer for Corn on Lakebed Soils Many producers use starter fertilizers because cold and wet conditions may occur zfter planting. In addition, startzr fertilizers may improve the efficiency of nutrient uptake by the crop in a sidedress system. Historically, producers in Northwest Ohio consider phosphorus the most important component of a starter fertilizer, even though research has shown that nitrogen provides most of the yield benefit. However, many fields in Northwest Ohio have more than adequate levels of phosphorus for corn... Download paper
2. Nitrogen Availability of Treated and Raw Dairy Manure There is minimal information on the nitrogen (N) availability and composition of treated manures. Knowing how N availability differs w ith manure treatment will result in better N crediting guidelines. Raw dairy manure and anaer obically digested manure were incubated with five typical Wisconsin soils for 112 d. Net N mineralized from the different N sources were compared. Nitrogen mineralizatio n differed by manure type and also by soil. Overall, the digested slurry and the digested separated liquid... Download paper
3. Use of Nitrogen Fertilizer Sources to Enhance Tolerance and Recovery of New Corn Hybrids from Early Season Soil Waterlogging Corn (Zea mays L.) production losses due to temporarily flooded or saturated soils resulting from excessive precipitation are a persistent problem in Missouri and the Midwest Region of the United States. In 2011 alone, monetary losses for corn and soybean (Glycine max) production due to excessive flooding in the Midwest were calculated to be more than $1.6 billion. Application of different sources of nitrogen (N) fertilizer may promote increased flood tolerance and recovery in interaction with different... Download paper
