  1. Drought Conditions Expand but Some Relief Ensues

    Author(s): Aaron Wilson

    As of the Thursday July 30, 2020 release of the U.S. Drought Monitor, 37% of the state is covered by D1- moderate drought conditions (Figure 1). Hot and mostly dry conditions continued through much of June and July, with only scattered areas of heavy rain throughout the state. This has depleted soil moisture and lowered stream flows. If you are seeing drought impacts in your area, consider submitting a report to the Drought Impact Reporter.

    Western bean cutworm (WBC) trap counts for the week of July 27 – August 2 show a downward trend in the majority of monitoring counties. Despite the overall decrease in WBC numbers, ten counties are currently at the threshold (an average of 7 or more) indicating to scout for egg masses including, Ashtabula, Fulton, Geauga, Henry, Huron, Lucas, Sandusky, Wayne, Williams and Wood. A total of 27 counties monitored 87 traps, resulting in 418 WBC adults (a statewide average of 4.8 moths per trap) (Figure 1). Monitoring for WBC moths will continue in many counties until the end of August.

  3. NRCS Seeks Comments on 590 Nutrient Management Standard Update

    Author(s): Greg LaBarge, CPAg/CCA

    USDA’s Ohio Natural Resources Conservation Service is inviting input, until August 31, 2020, during a 30-day comment period on their draft revisions to the Nutrient Management Practice Standard (Code 590). If approved, this Nutrient Management Standard would revise the current Ohio Field Office Technical Guide (FOTG) and provide the criteria and considerations required for all USDA Farm Bill financial and technical assistance related to the application of plant nutrients and manures.
