A Rupture Technique to Determine Fragipan Strength1
- C. T. Hallmark and

A method is presented to evaluate the strength of fragipans based upon the rupture of 1.2 cm thick disks cut from air dry soil cores. Rupture values abruptly increase in the fragipan as compared to overlying horizons and decrease with depth in the lower B3 and C horizons. Rupture strength measurements may prove valuable in objectively assessing fragipan development and its subsequent influence on water movement and root penetration.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
