  1. Crop Response to Potassium Fertilizer in Ohio

    Author(s): Greg LaBarge, CPAg/CCA

    Potassium (K) is an essential plant nutrient. We measure available soil K with a soil test and add fertilizers when the soil available K is insufficient to meet crop needs. There are economic benefits to making informed decisions about K fertilizer use. The under-application of K fertilizer can result in reduced yields, while over-application adds to input costs, with economic losses resulting from both scenarios.

    Application of Manure to Double Crop Soybeans to Encourage Emergence

    Author(s): Glen Arnold, CCA

    Wheat harvest is underway in parts of the state and some farmers are planting double-crop soybeans. The summer manure application window following wheat harvest is typically the 2nd largest application window each year. In recent years there has been more interest from livestock producers in applying manure to newly planted soybeans to provide moisture to help get the crop to emerge.

  5. Nutrient Loss from Field Fires

    Author(s): Greg LaBarge, CPAg/CCA

    A dry fall has led to an increased number of field fires. Farmers have asked a few questions about how a field fire impacts nutrients. A quick review of several Extension resources gives us helpful information. There are two things to consider in assessing the actual losses. One, how completely did the fire consume the residue? Second, what is the coverage area? The highest losses will be when the residue is absent.

    What nutrients are lost?
