Abstract

Soil structure is very often severely destroyed during high intensity burning, while low intensity prescribed burning is regarded to have a low or neutral effect on soil aggregation. In this issue of Plant and Soil , (Albalesmeh et al. 2012 ) report a novel mechanism of aggregate disruption during l...
