  1. Effects of Lime and Gypsum Application on Vegetable Yields and Nutrient Availability in Muck Soil

    Apr 19, 2022

    Applying lime to soil neutralizes acidity and subsequently increases pH, a major driver in nutrient availability. Managing pH in muck or organic soils (>20% organic matter) in Ohio differs from mineral soils, with a long-standing recommendation to keep organic soils at a target pH of 5.3 to minimize the risk of micronutrient deficiencies (Culman et al. 2020).
  2. Direct Marketing of Fruit Crops to Ohio Wineries

    Mar 11, 2022

    Ohio boasts a strong wine industry with wineries located across the state. The last 30 years has seen tremendous growth in the number of Ohio wineries due to a strong consumer demand, coordinated marketing efforts from Ohio Grape Industries Committee, and multifaceted and research-based extension programs from The Ohio State University. As of January 2022, there are 373 wineries in Ohio.
  3. The Role of Macronutrients in Equine Nutrition

    Mar 4, 2022

    Before creating a ration, it is essential to know the nutrient requirements for the type of animal you are feeding and the role of each nutrient class in the diet.
  4. Corn Yield Response to Damage from Strong Storms

    Feb 23, 2022

    Heavy rain events and strong storms are becoming more frequent in the eastern US corn belt, and have the potential to damage corn crops planted in the region. In addition to heavy rain and wind, hail may also accompany these storms. Damage to corn associated with these storms can manifest as reduced stand due to broken plants, partial to full plant defoliation from leaf loss, or as root lodging (stalks fall without breaking) or stalk breakage (i.e., greensnap).
  5. African Swine Fever: A Severe Threat to Swine Herds Is on the United States’ Doorstep

    Feb 18, 2022

    African swine fever is a disease caused by the African swine fever virus (ASFV). ASFV is a viral pathogen found primarily in sub-Saharan Africa. Recently, it has spread through China, Mongolia, Vietnam, parts of Europe and has been detected in the western hemisphere for the first time in over 40 years in the Dominican Republic and Haiti. It has never been found in the United States but remains a constant threat. The virus does not infect people but is devastating to domestic and wild pigs and kills up to 100% of infected animals.
  6. The Gastrointestinal Tract of the Horse

    Feb 18, 2022

    Horse owners and managers need a basic understanding of how the equine gastrointestinal tract (GIT) functions to provide ideal nutrition and management for animals in their care. This fact sheet provides practical knowledge of the physiology and function of the equine GIT and its relation to best practices. Fundamental knowledge of the gastrointestinal tract and how it relates to performance and health is essential to making informed decisions about equine feeding.
  7. Highly Pathogenic Avian Influenza

    Feb 15, 2022

    The flu is a contagious respiratory illness caused by influenza viruses. These viruses infect the nose, throat, and sometimes the lungs. Disease severity ranges from mild to severe illness and can cause death. The flu infects many different species including humans, pigs, horses, dogs, marine mammals, and birds, including wild birds and domestic poultry (Centers for Disease Control and Prevention 2017). There are four types of flu: Influenza A, B, C, and D (World Health Organization n.d.).
  8. Asian Longhorned Ticks in Ohio

    Feb 2, 2022

    Q: What are Asian longhorned ticks?
  9. Efficient Lawn Care Practices to Help Protect Ohio’s Waterways

    Feb 1, 2022

    Ohio has many water resources from small streams and ponds to regional lakes, rivers, and Lake Erie. Harmful algal blooms (HABs) can have a significant impact on water quality, which effects human health, the economy, and recreation. For example, the HAB of 2014 in the Western Basin of Lake Erie resulted in a two-day water ban for 400,000 Toledo residents. The estimated economic impact of this event was $65 million (NOAA n.d.). HABs are now common enough to warrant annual forecasting. Several factors impact algae and water quality.
  10. Advancements in Technology for Reduction of Pesticides Used in Orchards and Vineyards

    Jan 26, 2022

    One of the most significant technological advancements for reduction of pesticide use in orchards and vineyards happened more than four decades ago: a rate controller on a sprayer. These gadgets enabled sprayer operators to keep the application rate constant, regardless of changes in ground speed. They are now a standard component on every new sprayer sold. No other significant developments occurred in spray technology for a couple of decades until the introduction of these innovations:
