    Rainfall over the past weekend helped some drought stressed corn fields, especially late plantings, but it may have been too late for others.  Prior to this rainfall, according to the U.S. Drought Monitor, 46 percent of Ohio was rated as in “moderate drought” (https://www.nass.usda.gov/Statistics_by_State/Ohio/Publications/Crop_Progress_&_Condition/index.php). That area covered most of northern Ohio.

    The three primary sources of new Palmer amaranth infestations in Ohio so far have been:  1) presence of Palmer seed in the cotton-based feeds that are brought here from the south; 2) movement of contaminated combines from Palmer-infested areas of the south to Ohio; and 3) presence of Palmer seed in seed for conservation plantings (cover crop/CRP/wildlife/pollinator), which comes from states farther west such as Texas and Kansas.  The latter mechanism has gained some notoriety lately in Iowa, where Palmer amaranth was found in conservation plantings in four counties due to the planting of a

    Have very dry soil conditions increased the potential for toxic levels of nitrates in corn harvested for silage? Nitrates absorbed from the soil by plant roots are normally incorporated into plant tissue as amino acids, proteins and other nitrogenous compounds. Thus, the concentration of nitrate in the plant is usually low. The primary site for converting nitrates to these products is in growing green leaves. Under unfavorable growing conditions, especially drought, this conversion process is retarded, causing nitrate to accumulate in the stalks, stems and other conductive tissue.

    Some of you may remember the 2012 growing season—very dry most of the year but, in some areas, late season rains gave a second life into the soybean crop that was reaching pod fill stage.

    Do you have pesticides sitting in storage that you do not intend to use?  The Ohio Department of Agriculture will be sponsoring four Ohio Pesticide Clean Sweep Days around the state for farmers wishing to dispose of unwanted pesticides on four different dates in August.  The pesticide collection and disposal service is free of charge, but only farm chemicals will be accepted.  Paint, antifreeze, solvents, and household or non-farm pesticides will not be accepted.

    Decisions made at planting time are critical in getting any crop off to the best possible start. The technology and agronomic research we have today can help farmers maximize planter performance for optimal crop yields. Join OSU Extension and Champaign County Farm Bureau on August 26 for the second annual Precision Ag Day. This year the focus will be on planter technology.

    A three-hour fertilizer applicator certification training program will be held by The Ohio State University Extension on Monday, August 29, from 6:30 to 9:30 PM at the Palazzo in Botkins, Ohio.  Refreshments will be served at 6:00 PM.  Topics that will be discussed include the current status of water quality, soil sampling, and phosphorus and nitrogen management.  Anyone involved in agricultural production and applying fertilizer to greater than 50 acres must obtain this certification prior to September 30, 2017.  After this date, a test could be required to obtain this certification.  This
