Adverse Weather & Environmental Factors


  • Consequences of Planting in Wet Soils

    Early planted corn and soybeans have done well the past few years, but focus should be on soil conditions rather than the calendar when deciding to start planting. The two most important soil factors are temperature and moisture. While emergence problems can occur if soil temperatures are below 50°F, planting into soils that are too dry or too wet will lead to more season-long issues.

  • Wind Damage from Summer Storms

    Corn can be impacted by summer thunderstorms that include heavy rain and wind. The timing of the storm relative to the stage of growth and many other agronomic factors can determine if root lodging occurs or green snap of plants may happen.

  • Planting In Cold Soils

    Maximizing the genetic potential of a hybrid starts at planting. Many factors affecting germination and emergence are environmental, but there are decisions and actions completely under our control that can improve our chances of a successful start to the corn growing season. You raise your chances of success if you’re simply mindful of the risks and rewards of planting early, and make well informed decisions on a field by field basis.

  • Saturated Soils and Early Season Cold Stress

    Many factors, both environmental and field specific, will influence the extent of damage that will occur from cold stress early in the season. Knowing what symptoms to look for and having patience when evaluating damage will allow you to make the best decision for your corn crop.

  • Frost and Freeze Damage to Corn

    Recent cold temperatures may impact emerged corn plants. Some corn may struggle to emerge due to an extended cold period. The key requirement for assessing freeze damage is to be patient and to allow the plants to recover. While corn leaves may blacken and wither within a day after frost occurs, the true extent of plant damage may not be evident.

  • Effects of Flooding and Saturated Soils on Corn

    Areas of fields that are not flooded with standing water may still remain saturated for an extended period of time. Survival of corn plants is dependent on temperature, stage of growth and length of time the soil is saturated. There is no way to tell for sure whether a corn field will survive until enough time has passed to assess recovery of affected plants.

  • Managing Corn in a Sustained Wet Environment

    Despite reports of a good to excellent corn crop in the Midwest, there are considerable acres where performance has been impacted by excessive rainfall.

  • Effects Of Compaction On Corn Seedlings

    There are not a lot of mechanical options for alleviating compaction once it has formed. If you receive some rainfall, it can loosen up the sidewall or compaction layer enough for the roots to push through and break it up. Being able to recognize and diagnose compaction will keep you from spending money unnecessarily. Many times what may look to be nutrient deficiency or irregular development could, in fact, be the result of compaction.

  • Green Snap in Corn

    Green snap is a term to describe breakage of the stalk of the corn plant by high winds. This yield-robbing, weather-related phenomenon occurs primarily in areas of the central and western Corn Belt where high winds are more prevalent.
