Between 150 to 250 ppm of the chemical in the seed row are sufficient to induce fracturing in most soils. The actual amount needed is a direct function of the base exchange capacity and CaCO3 content, and an inverse function of the organic matter content of the soil treated.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
