Abstract
Summary A thin layer of soil was washed from a smoothed soil profile and the length of the roots visible at the profile wall estimated. A grid net was used to count every visible part of a root which was nearly 5 mm long. Roots which were longer than 5 mm were counted more than once. This improvement of the traditional trench profile method provides an estimate of the root length in a soil volume.Keywords
