The yield-till® system bands nutrients in the root zone, building on crop residue management and soil tilth, setting the stage for great Seed Bed Conditions. Banded nutrient placement in the root zone is the most efficient means of supplying plant food needs throughout the growing season. Nutrients may be present in high amounts, but the ability of the plant to take up those nutrients through the root system is what really matters. Roots take up more nutrients with good soil tilth. Placing fertilizer in the root zone, where more soil moisture is present, maximizes the availability and return on investment of that fertilizer. Root Zone placement also minimizes nutrient tie-up with surface residue. Root Zone Banding nutrients reduces fertilizer runoff and improves availability. Nutrient availability is much more important than nutrient amount.
