Nutrient deficiencies usually show up first in distinct areas of the field. As you walk the fields look for patterns that could indicate that you may have a nutrient deficiency problem.
From striped leaves to inverted yellow “V” leaves starting at the tip of the leaf and going back the middle of the leaf could be indications that you have a nutrient deficiency.

So far, summer 2015 has been one of the rainiest on record. Cool, wet conditions can favor the development of white mold in soybeans, a fungal disease that can substantially affect your yield by reducing seed number and weight. Symptoms of white mold, which is also known as sclerotinia stem rot, include a fluffy, cotton-like white substance on plant stems and pods, bleached stems and wilted leaves.
In this conducive environment, growers may want to consider applying a fungicide. Several fungicides are approved for preventing and managing white mold — contact your co-op at 814-793-2721 for personalized recommendations.
Other ways to reduce the impact of white mold include:
- Rotating crops. The spores that cause white mold can survive in soil for several years, so rotating crops in fields with a history of the disease can reduce future outbreaks. Other steps you can take include reducing tillage in fields that have a history of the disease in order to prevent spores from surfacing.
- Plant and row spacing. Dense canopies and tightly-spaced rows are more favorable to white mold outbreaks.

Area farmers may be concerned about the unusually high rain amounts we’ve seen this June and how this might affect corn and soybeans. Here are some issues to consider, and resources that can help. As always, call your co-op at (814) 793-2721 for personalized, expert advice on any topic related to growing corn or soybeans.
Corn: Nitrogen in nitrate form can leach from the soil into groundwater in wet conditions, which is a particular concern for corn. Although there’s no diagnostic test that can determine the exact amount of nitrogen in soil, a simple point system has been developed that can help you decide whether an additional application of nitrogen would be beneficial. Visit the C.O.R.N. (Crop Observation and Recommendation Network) newsletter from The Ohio State University for details on how to evaluate your cornfields using this system.
Soybeans: Adverse effects of too much rain on soybeans can include reduced oxygenation of the roots, resulting in poor nodulation. Plants that are completely flooded for 24-48 hours might even die if the temperature is high enough. Also, saturated soybean fields are more likely to develop diseases due to water molds, once your plants have reached the V2 growing stage. The C.O.R.N. newsletter has more on these problems.
Being able to identify crop stages in soybeans is important in crop management, because stress affects soybeans differently at different stages. Minimizing stress during reproductive growth stages is vital to ensuring a good yield. For more on this topic, consult a illustrated, downloadable PDF from Channel, here.
Finally, with the wet and humid weather we’ve experienced lately, it’s a good idea to keep an eye out for fungal diseases in soybeans. Scout your crops regularly to watch for these diseases, and time fungicide applications carefully! Click here for a downloadable PDF from Channel on this topic.

There is a possibility of frost occurring over Friday evening in the area. Bedford Farm Bureau Co-op advises you to check on your crops next week for response to these low temperatures. Channel has a few tips on how to ensure your corn and soybean crops survive these unexpected cold snaps.
- Corn growth stage, air temperature, soil moisture, soil texture, and topography can influence potential cold injury to corn plants.
- Frost with temperatures above 28° F may damage seedling leaf tissue without necessarily injuring the growing point.
- Temperatures below 28° F may injure or kill the seedling growing point, even if the growing point is below the soil surface.
- Growers should wait 3 to 5 days after a cold to check for plant damage
- Soybeans respond differently to frost compared to corn, as the growing point is exposed to weather as soon as the cotyledons emerge.
- Understanding the effects of weather conditions on soybeans at different growth stages can help determine the best management options.
