1. Soybean Response to Sulfur Placement and Starter Fertilizer ApplicationReduced rates of early season nutrient mineralization from earlier planting dates, increased nutrient removal from greater yields, and reductions in atmospheric sulfur (S) deposition have increased concern regarding S availability for optimal soybean (Glycine max L.) growth. A field study was established to determine the effects of 25 lbs. S per acre with or without starter fertilizer consisting of 20 lbs. nitrogen (N) per acre and 50 lbs. P2O5 per acre on soybean grain yield and quality. Main plots... |
2. Assessing the Use of Enhanced Efficiency Fertilizers on Sugarbeet Yield and QualityA field study was initiated in Frankenmuth, MI to study the effects of enhanced efficiency fertilizers in comparison to standard nitrogen (N) programs on sugarbeet (Beta vulgaris L.) yield and quality. The study was arranged as an 8 treatment randomized complete block design with four replications. All treatments received 40 pounds N/A as 28% UAN applied as a 2x2 (in) at planting with total N applications at 160 pounds N/A. Treatments consisted of urea sidedressed with light cultivation, N applied... C. Bauer, K. Steinke |
3. Corn Growth and Yield Responses to Pre-plant and In-season Nitrogen CombinationsIn-season N applications may help synchronize N availability with corn uptake but further investigation is needed to validate different combinations of pre-plant and in-season N strategies. Field experiments were initiated in 2014 to investigate corn response to N management programs involving multiple N-placements, timings, and sources applied at a single N rate at two Michigan locations. Nitrogen management programs were grouped into three strategies utilizing broadcast pre-plant incorporated (PPI)... |
4. Planting Date, Nitrogen Rate, and Nitrogen Timing Interactions to Optimize Winter Wheat ProductionWinter wheat (Triticum aestivum L.) planting date is a large contributing factor for high yield production systems located within the central Great Lakes Basin, and nitrogen (N) rate and timing strategies offer the opportunity to improve both the production and efficiency of winter wheat when considered in combination with planting date. A field study was initiated in East Lansing, MI to determine the effects of planting date, N application timing, and total N application rate on winter wheat yield... |
5. Quantifying the Effects of Nutrient Management and Cover Crops on Soil Microbial Communities and Soybean ProductionAgricultural productivity relies upon microbial communities to cycle nutrients from soil to plant yet little information is available concerning how nutrient management and cover cropping practices influence microbial activity and crop production. Lack of consistent soybean (Glycine max L.) yield response to applied fertilizer has resulted in a need to further investigate management practices focused upon enhancing soil biological activity which in turn may feed the crop. A field study was initiated... |
6. Relationship between Nitrogen Rate and Weed Removal Timing on Corn YieldWeeds actively compete for nitrogen in corn grain production systems. Field studies were conducted in 2009 and 2010 at the Michigan State University Crop and Soil s Research Farm in East Lansing , MI to evaluate the effect of N application rate and weed removal timing on grain yield . Treatments included four preplant incorporated rates of urea (0, 67, 134, and 202 kg N ha - 1 ) and four weed removal timings (5, 10, 15, and 20 cm) based on average weed canopy height. An additional season- long weed-free... |
