1. Is There a Better Way to Fertilize Corn with Potassium?Potassium (K) is among the most abundantly needed plant nutrients. A 15.7 Mg ha-1 (250 bushel acre-1) corn (Zea mays L.) crop accumulates anywhere from 168-225 kg K2O ha-1 (150-200lbs K2O acre-1) over the course of a growing season, and according to the IPNI Soil Test Summary (2015), about 37% of Illinois’ soil tests are deemed as deficient for K. The objectives of this study were to investigate various methods of... S. Foxhoven, F. Below |
2. Polyhalite Alters the Uptake and Partitioning of Mineral Nutrients in MaizeModern maize (Zea mays L.) hybrids coupled with advanced agronomic practices have led to an increased yield potential on many US corn acres. To realize these higher yields demands a better understanding of crop nutrition. The objective of this study was to document the pattern of uptake, partitioning, and remobilization of nutrients released after potassium fertilization, specifically muriate of potash (MOP; 0-0-60) and/or polyhalite fertilizers (0-0-14-6Mg-17Ca- 19S)....

3. Can Kura Clover and Winter Rye Covers Mitigate Nitrate Leaching In Irrigated Sands?Cover crops are gaining more popularity as a mitigation tool to prevent nitrate (NO3--N) leaching from the corn (Zea mays L.) and soybean [Glycine max (L.) merr.] fields of Minnesota. Leaching of NO3--N is not only a monetary loss for growers, but also results in groundwater contamination. Winter rye (Secale cereale), a commonly grown cover crop in Minnesota and kura clover (Trifolium ambiguum), a less... |
4. Banded Fertility: Music for Higher Corn YieldsThere is a need in production agriculture to reduce nutrient loss to the environment and implement more sustainable production practices, but grower adoption has been slow and inconsistent due to fear of reduced yields and profit. However, if new fertilizer technologies can be used to increase nutrient use efficiency and grain yield simultaneously, grower willingness to adapt environmentally sustainable practices is far more likely. We implemented a two-year corn (Zea mays L.) yield study... S. Foxhoven, F. Below |
5. A Minnesota-Wide Assessment of Critical Pre-Plant and in-Season Soil Nitrate for Adjusting Nitrogen Rate GuidelinesThe pre-plant (PPNT) and pre-sidedress (PSNT) soil nitrate tests are often used as indicators of soil nitrogen (N) availability in Minnesota. The assessment of available soil nitrogen (N) provides corn (Zea mays L.) growers with key information on N credits to adjust their N fertilizer rates. However, current N management recommendations in Minnesota were based on research conducted 40-yr ago and did not specify differences between environments and management. Through a comprehensive...
