    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

    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

    The FSR Nutrient Management Field Day is September 14th. We will make use of the site and facilities of the Farm Science Review’s Molly Caren Agricultural Center, near London Ohio the week before that event. Check in at 8:30 for a 9 AM start and plan to end the day by 3PM.

    We will break into small groups so you get an up close and personal educational experience for the morning. Starting at 9 AM we will run through the Agronomy Demonstration
