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.
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.
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:
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:
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.
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.
Across much of the United States, autumn is marked by a series of chemical changes in leaves, resulting in them changing colors from green to red, orange, yellow, or gold. This change in leaf color combined with their subsequent drop is part of the tree’s ability to survive winter weather (Chaney, 1997).
Traveling with young people can be a very rewarding experience. In order to be successful, chaperones must be prepared and understand proper policies and procedures. Additionally, chaperones must avoid generalizing to teen characteristics, understand the developmental needs of participants and think about how to create a youth-adult partnership throughout the experience (Curtis, 2015).
A common statement frequently heard when unwelcome diarrhea or vomiting occurs is, "It must be something I ate." Often it can be traced to improper handling of food; however, norovirus can be spread through both food and nonfood sources. You can get norovirus from eating contaminated food or water, coming into contact with someone who has norovirus, or touching contaminated surfaces and then putting unwashed hands in or around your mouth.
