Soybean growers have a new way to head off the yield and plant development problems associated with Iron Deficiency Chlorosis (IDC) in soybeans while also addressing zinc and manganese needs of the crop.
Data from trials using a new micronutrient formulation that is compatible with glyphosate show a surge of iron uptake along with increases in zinc and manganese, according to Agro-K. The trials also showed a 6 to 8 bu/acre yield increase with the nutrients.
Farmers working with Simplot Grower Solutions in 2009 in North Dakota and Minnesota applied two applications of Sysstem-Ready zinc and manganese tank mixed with glyphosate. In just a few days tissue analysis showed that in one field average zinc readings went from 14 ppm to 47 ppm, manganese went from 108 to 628, and iron went from 14 to 7,789. In a second field zinc went from 16 to 34 ppm, manganese from 90 to 483, and iron from 192 to 4,922. Agronomists reported there was no toxicity from the iron increase.
