1. Soil Fertility Research in ManitobaA listing of current soil fertility research being conducted by the University or Manitoba, Agriculture and Agri-Food Canada (AAFC) and provincial extension (Manitoba Agriculture and Resource Development). Crops under study include corn, soybeans,, field peas, dry beans, spring wheat and canola. ... J. Heard |
2. Seed Germination as Influenced by Fertilizer Type, Seed Coating, and Duration of StorageOverseeding forages into existing pastures and hayfields helps maintain dense stands and sustain productivity. Fertilizer applications to stimulate early spring growth provides an opportunity to blend forage seed with fertilizer. Additionally, seed treatments are often used to improve the ability to handle small seeds and to improve percent germination over raw or uncoated seed. Little is known about how seed coating, fertilizer type or duration of exposure to fertilizer will influence seed g... E. Ritchey, C. Teutsch |
3. Soybean Growth and Yield Effects from Starter Fertilizer and Nitrogen ApplicationSpring Michigan weather variabilities and earlier planting dates may provide opportunities for starter fertilizer to affect soybean (Glycine max L) early season dry matter production while also decreasing the time interval for nutrient accumulation (i.e., lag-phase), but impacts on initiating biological N fixation (BNF) are not well known. Two trials were established near Lansing, MI to examine the effects of starter fertilizer and multiple nitrogen (N) application timings across two... K. Steinke, S. Soat |
4. Nitrogen Timing Fertilization Strategies for Winter Wheat in WisconsinEconomically optimum winter wheat (Triticum aestivum L.) production relies on effective N application rate and timing. Previous research in Wisconsin indicates a need to better understand winter wheat response to N rate and application timing for growing conditions specific to the state. This study evaluated the effect of N application timing on yield, economic optimum N rate (EONR), agronomic N use efficiency (NUE), and profitability. A three-year study was conducted at three locati... J.D. Jones, C.A. Laboski, T.W. Andraski |
5. High Gypsum Application Rates Impacts on Iowa Soil Properties, Dissolved Phosphorus Loss, and Crop YieldGypsum (calcium sulfate) is a common sulfur (S) source for crops and rates in the northcentral region seldom are > 250 lb/acre. It is known that even higher gypsum rates do not raise soil pH. Research in eastern or southeast states showed that in some conditions high gypsum rates can improve other chemical or physical properties and can reduce dissolved phosphorus (P) loss from fields. However, little research has evaluated potential benefits in prairie-developed soils of Iowa and the regi... A.P. Mallarino, M.U. Haq |
