Summary
It is shown that root maximum growth pressures, root buckling stresses, and soil penetration strengths and all non-normally distributed with positive skew. It is found that a Beta distribution, with assigned end points, provides an extremely good fit in each case. It is recommended that this Beta distribution is used in the development of mathematical models for root growth in soil.
