  1. Ohio Weather Pattern 6-4-2018
    Author(s): Jim Noel

    As summer nears, the weather pattern supports an increasing risk of big differences in rainfall totals from too wet to too dry.

    There is a growing risk of a heat dome developing off the drought area in the south central to southwest parts of the U.S. The heat dome will expand northeast into parts of the corn and soybean belt from time to time over the next several weeks. This means enjoy the cooler than normal weather this week. Storms will ride along the northern edge of

  2. Early Corn Coloration – Green, Purple, or Yellow?
    Author(s): Alexander Lindsey, Steve Culman, Peter Thomison

    Corn seedlings often turn yellow (due to low nitrogen uptake and/or limited chlorophyll synthesis) or purple (reduced root development and/or increased anthocyanin production) under cool, wet conditions. Some hybrids are more likely to increase anthocyanin (purple pigment) content when

    Much of the region’s alfalfa crop has been harvested over the past two weeks.  As cooler temperatures move into the area regrowth will likely slow down. Once regrowth reaches 16 inches tall again, the NDF (neutral detergent fiber crude protein) can rapidly be estimated in the field using the predictive equations for alfalfa quality (PEAQ).

    Author(s): Steve Culman, Peter Thomison

    Leaf striping (interveinal chlorosis) in corn is appearing in many Ohio fields.  There are several nutrient deficiencies (including sulfur, zinc, magnesium, and manganese) that result in leaf striping and some of these look similar. The severity of the striping may vary considerably within a field and may be associated with differences in soil pH, organic matter, compaction, tillage

    Many questions come into the County Extension Office daily.  Many times those include a question about a weed identification.  During the month of June 2018, OSU Extension will be featuring a weed identification of the week.  This week's weed is cressleaf groundsel, Senecio glabellus. 

    Cressleaf groundsel is a member of the Aster/Composite family.  Cressleaf groundsel can go by many other common names like butterweed, yellowtop, golden ragwort, and yellow ragwort.  It
