TY - JOUR T1 - A Practical Guide to the Use of Steel Rods for the Assessment of Aeration in Urban Soils JF - Arboriculture & Urban Forestry (AUF) JO - JOA SP - 289 LP - 294 DO - 10.48044/jauf.1993.046 VL - 19 IS - 5 AU - S. J. Hodge AU - K. Knott Y1 - 1993/09/01 UR - http://auf.isa-arbor.com/content/19/5/289.abstract N2 - Diagnosing the reason for poor performance of urban trees requires a means of evaluating soil physical conditions. Soil aeration status can be inferred from the corrosion of steel rods inserted into the ground. The technique is inexpensive, non-destructive and can provide information on the vertical distribution of anaerobic conditions. Practical aspects of the use of steel rods and their interpretation are described. ER -
