High soil pH a concern?

A great harvest starts in the SPRING when planting the right seed on your unique acres. Growers often reference corn suitability ratings to provide valuable insight to a hybrid’s strengths and weaknesses, and how that translates into productivity and profitability for their acres.

Know your soil profile

When it comes down to seed selection, growers should take into account the soil profile in each field. High soil pH is a common challenge in the Western Corn Belt. Decreasing soil pH through management practices is very difficult and typically not economical, so what should a producer do? “Plant a hybrid with good tolerance to high soil pH, a suitability score of 5 or higher,” states Craig Langemeier, Hoegemeyer sales agronomist.

The effects of high pH soils

Hoegemeyer is committed to providing growers products that can tolerate these stressful pH conditions. High pH soils cause a symptom known as Iron Deficiency Chlorosis (IDC). Several nutrients become harder for the plant to extract from the soil at a pH above 7.5 including phosphorus, zinc, iron and manganese. This may cause stunting, yellowing, interveinal chlorosis and even plant death in some hybrids.

Commitment to research

Hoegemeyer conducts extensive research on all products before they are brought to market. Research efforts have recently ramped up to provide high-performing pH tolerant products growers demand. During the 2016 growing season, replicated trials were conducted with over 70 entries at two high pH environment locations. This research aids in providing the right seed to perform in your soil type.

Selecting the right seed

Do you have high soil pH? Do you have the right seed to perform these acres? Different genetics are going to perform differently on each soil type, be confident you’re selecting the right seed for your farms – talk to your local Hoegemeyer dealer for placement recommendations.  Check out the Hoegemeyer brand hybrids that are recommended for high soil pH here.
