1. Microplastics in Sweet Corn: Polymer Coated FertilizersPolymer coated fertilizers enhance nutrient efficiency and potentially reduce environmental nutrient loss. However, heavy runoff can carry microplastics into waterways and could negatively impact aquatic or terrestrial environments (Alimi, 2018). The objective of this project is to determine the microplastics concentrations in runoff water in sweet corn (Zea mays ‘sweetness’) with various placement methods. The full factorial study design consisted of three fertilizer... B.G. Hopkins, B.T. Geary, C.J. Seely |
2. Microplastics in Urban Landscapes: Polymer Coated FertilizersThe introduction and use of polymer coated fertilizers in urban landscapes has proven beneficial in supplying nutrients with less loss to the environment. However, these have recently come under scrutiny due to concerns with microplastics in the environment (Alimi). The objectives of this study were to determine the microplastics concentrations in runoff water in urban landscapes. The full factorial study design consisted of three fertilizer sources (Uncoated Dry and Coated Dry) with all... C.J. Seely, B.T. Geary, B.G. Hopkins |
3. A New Hydroponic System for Testing Mineral Nutrient Deficiencies and It's Application to SoybeansCorrelating plant tissue nutrient concentrations with visual symptoms is valuable in combating mineral nutrient deficiencies and toxicities. Due to changing climates and decreasing water supplies throughout the world, agricultural lands need to improve nutrient and water management in crops, including soybeans (Glycine max L.).Because nutrient concentrations can be easily controlled, hydroponics effectively demonstrate isolated specific nutrient related symptoms. However, many hydroponic... A.M. Lambert, S.M. Anderson, D.L. Cole, A. Haderlie, C.J. Seely, B.G. Hopkins |
4. Shining Light on Novel Pathways for Potassium Fixation in SoilCotton has a high demand for potassium, and potassium significantly affects both cotton yield and fiber quality. Thus, bioavailability of potassium from the soil is paramount. Bioavailability and leaching of potassium to crops and from soils has been studied since the 1940s. However, problems that confronted agronomists in the 1980s continue to impact growers and crop production, including unpredictable potassium bioavailability and inconsistent plant response to fertilizer application under a...
