1. Effect of Nitrogen Rate and time of Application on Mefluidide Treated Smooth Brome Livestock producers who graze beef cattle or dairy animals usually have an abundance of pasture during spring when cool-season grasses grow rapidly. As hot, summer weather arrives, cool-season grasses cease vegetative growth and produce seed. Forage quality decreases as the grasses become dormant. Without alternative pastures or forages, cool season pastures become over-grazed and cattle performance is reduced. Using pastures composed of warm-season grasses that produce maximum dry matter during... Download paper
2. Effect of Chlorophyll Meter Readings on Improving Nitrogen use Efficiency in Corn Production Chlorophyll meters have received widespread publicity as tools to measure nitrogen status of corn. Less information is available on whether the use of chlorophyll meters will decrease total nitrogen use or increased corn grain yield. One question that remains is, "How low chlorophyll readings need to go before additional nitrogen is needed?" To determine the impact of a 2 and 4% reduction in chlorophyll readings impact on yield (as measured by a SPAD 502 meter) zero, 50, 100, 150 and 200 lbs Ntacre... Download paper
3. Site-Specific Manure Application Effects on Corn Yield and N Status Manure, a renewable resource, is an excellent source of nutrients that can be substituted for synthetic types of fertilizers. The organic matter in manure can enhance the physical and chemical properties of soils, especially infertile soils, as these soils typically contain low levels of organic matter and nutrients, and have low water holding capacities. The objective of this study was to evaluate the ability of manure application for improving crop yield and N status in less productive areas within... Download paper
