Corn Root Experiment
PRODUCT: MAXGreen Crop Enhancer
You can get a close-up of root growth in a “terrarium” like this, which we built in late spring 2009. Two soil-filled growth chambers each about a foot wide, three feet deep and six feet long, have glass sides. During the growing season, the glass is insulated with solid foam board and protected from the sun with reflective roofing. Air circulates behind the roofing to keep the soil at a nearly constant temperature. At season’s end, you remove the glass and wash away some of the soil to examine root growth under varying treatments. In our experiment, corn was seed-treated with MAXGreen Crop Enhancer, then planted in a standardized soil mix and sprayed twice with MAXGreen Crop Enhancer at V2 and V4. No extra water was applied except at planting, then again during three dry weeks in early September.
MAXGreen Crop Enhancer-treated corn had more massive roots with more root hairs, as shown in the photos above. But the difference was most clear when we washed away all the soil and hung up the roots for comparison (below). If dry weather hits, this is when big roots bolster yield.
