Growers face many obstacles every year that directly affect their crop yields. One main player, although an unwelcome one, for soybean crops in key areas of the Midwest is iron deficiency chlorosis (IDC). IDC occurs when plant roots can’t reduce iron to a soluble form that can be taken up by the plant to help with its normal and optimal development processes. IDC is typically due to three key soil indicators, including high levels of calcium carbonate in the soil; saline soils and alkaline soils (pH levels over 7.5). This lack of available iron creates a chlorophyll imbalance in the plant and causes the characteristic yellow leaves typically seen in plants with IDC. Fields effected with IDC can have devastating results, from a significant yield loss (up to 50% or more) to a total loss of the crop depending on the severity.
Unfortunately, 2017 is looking to be a banner year for fields to develop IDC. Growers across the Red River Valley and throughout central Minnesota saw the perfect storm for conditions that supported the development of IDC, even in fields that had not previously seen these issues. These conditions included the cooler temperatures early in the season, along with the nitrate buildup from fields that were planted with corn the previous year. With this increase in conditions more favorable to increasing the effects of IDC, it’s even more important for retailers to take a leadership role when advising their growers about the potential impacts from fields prone to developing IDC. It is also important for them to provide proactive and effective solutions to help their growers minimize the negative impacts and avoid yield and crop loss from IDC.
Finding the Best IDC Solution
First, growers need to determine if their field has soil with a high pH level and the other key indicators for IDC. If they determine their fields have a higher risk for or have historically shown to have IDC, they need to determine the appropriate actions with their retailers for preventing IDC in their crop.
The most recommended method for growers to treat for IDC is to apply an iron-chelated fertilizer in-furrow when planting soybeans. This allows the soybean seeds the best chance from the start of their growth cycle to access the iron needed to develop into a healthy and high yielding soybean crop.
In 2016, North Dakota State University (NDSU) conducted a competitive study funded by the North Dakota Soybean Checkoff to see if there was a difference in iron-chelated fertilizer products. From the results (shown on pages 14-15) there is definitely a difference in iron-chelated fertilizers. The study included Soygreen (shown as Fe-EDDHA-1 in the study) along with three top competitors. The study looked specifically at the amount of ortho-ortho chelated iron (EDDHA) in each product, plus the product’s long-term performance. When compared with the three competitors, Soygreen led with the best results in the following areas:
- Highest percentage of ortho-ortho chelated iron
- Highest percentage of water soluble “soil stable” iron and
- The best results through multiple crops of soybeans
According to this study, Soygreen with 80% of its iron in the recommended ortho-ortho form consistently provided more soluble iron to the plants than its competitors and provided a longer and more positive response in the soybean plants, especially in subsequent crops proving once again why Soygreen is the market leader in preventing IDC in soybeans.
West Central has 14 years of results showing how Soygreen helps increase yields and prevent IDC. Field trials comparing Soygreen versus an untreated field, show an average increase of 8.2 bushels per acre with some results as high as 40 bushels per acres for the Soygreen treated fields.
With West Central’s newest IDC product, ag retailers can now offer their customers three different options for combatting IDC – the original Soygreen, in a dry or liquid formula and the new Soygreen Granular developed for the air seeder market, providing another effective solution to fit growers’ needs.
Get the best Results – Combat IDC with Soygreen Granular
The introduction of Soygreen Granular allows retailers in the northern tier of the U.S. an IDC solution for their growers who use an air seeder to plant soybeans. Previously, these growers didn’t have the option to apply Soygreen during planting. With Soygreen Granular, growers who use air seeders to plant soybeans now have the option to apply Soygreen during planting to help them battle IDC. This new option helps them protect their soybean yields, without having to incur additional time and money to switch out or rent additional equipment.
With multiple strip tests in North Dakota during 2016, fields planted using Soygreen granular saw increases from 4.8 to 17.8 bushels per acre with Soygreen versus the untreated fields. This relates the results of this new formulation to the previous tests performed with the original Soygreen.
In field tests with a leading competitor this season, Soygreen Granular is also outperforming the leading competitor as shown in the images below.
With more than 14 years of proven results, the West Central Distribution Soygreen portfolio is an even more powerful industry leader, providing the leading IDC solution in three convenient options: Soygreen, Soygreen Liquid and the new Soygreen Granular.
