  1. Opportunities for Sub-surface Nutrient Placement in Ohio

    Feb 23, 2024

    The ability to place fertilizer and other soil amendments below the soil surface can be a powerful tool for producers in Ohio. Implements that perform this function can vary in horsepower requirements, the level of tillage and soil disruption, depth of fertilizer placement, and fertilizer placement capabilities. However, when considering strip-till with fertilizer banding, one needs to evaluate the equipment setup and implementation process for strip tillage and fertilizer banding.
  2. Forage Testing for Beef Cattle

    Feb 19, 2024

    Forage quality changes with maturity and storage. A forage test can provide useful information about the nutritive value of hay or pasture. This information can be used to adjust the amount of supplement fed to beef cattle. If forage quality is high, the producer can feed less supplement, resulting in savings. Conversely, if the forage quality is low, diet supplementation can improve animal performance and increase profits.
  3. Raw Oat Safety

    Jan 30, 2024

    Raw oat dishes, such as overnight oats, are a great option for a healthy make-ahead breakfast or lunch. They can be endlessly customized to fit a variety of flavor preferences and dietary restrictions.
  4. Annual Bluegrass Weevil

    Jan 29, 2024

    The annual bluegrass weevil (ABW, Listronotus maculicollis Kirby), one of the “snout beetles” in the family Curculionidae, is a destructive pest of short-mown turfgrass in golf courses and sports fields. Adults measure less than 1/5 inch (< 5 millimeters) in length, with antennae near the end of their snout (Figure 1). Newly emerged adults appear mottled brown, while older adults are shiny black.
  5. Potassium Uptake and Ohio Crop Response

    Jan 19, 2024

    Potassium (K) is a macro nutrient needed for crop production. Annual K removal rates for grain crops at state average yields are 45–100 pounds per acre annually, while forage crops are 200–300 pounds per acre annually. The primary function of K is to maintain a charge balance between positively charged ions (cations) and negatively charged ions (anions). Maintaining this balance supports plant functions. While most Ohio soils have an abundance of total K, only a small portion of total K is plant-available.
  6. Soil Phosphorus and Crop Response to Phosphorus Fertilizer in Ohio

    Jan 18, 2024

    Phosphorus (P) is critical for crop production but also poses a threat to water quality in Ohio. Therefore, a better understanding of optimizing the P availability to crops while minimizing the potential of P to pollute water bodies is important.
  7. Drones for Spraying Pesticides—Opportunities and Challenges

    Jan 17, 2024

    Although most aerial pesticide spraying in the United States is done using traditional fixed-wing aircraft, use of smaller, remotely piloted aircraft has been gaining significant acceptance by pesticide applicators in many other countries. A variety of names and acronyms are associated with remotely piloted aircraft:
  8. Lawn Mowing

    Dec 27, 2023

    Mowing, the controlled defoliation of turfgrass, is a cornerstone practice in lawn management. This repetitive, partial stressor triggers a multifaceted response in the plant, dictating the need for subsequent interventions. Proper mowing practices are pivotal, regardless of fertilization, irrigation, or pesticide applications, for cultivating and maintaining a high-quality lawn. Properly mowed lawns have several advantages:
  9. Ripe Rot of Grape

    Dec 19, 2023

    Ripe rot is a late-season disease that primarily occurs in warm, moist, growing regions in the southeastern United States. However, outbreaks in Ohio and other states in the Midwest and Northeast occur when conditions are warm and wet during fruit maturation. The disease is caused by multiple species of the fungus Colletotrichum.
  10. It’s a Bird, It’s a Plane, It’s a Moth: The Sphinx Moths of Ohio

    Dec 18, 2023

    If you spend a lot of time around flowers, you may have noticed large, hovering pollinators that look and sound like hummingbirds, but on closer inspection are not birds at all; they are insects. These are the large moths known as sphinx moths, hawk moths, or hummingbird moths.
