winning the battle against erosion and non-wetting soils without covering the farm in trees

Key Messages
• Spading is a useful farming practice to incorporate shallow clay in the top soil profile.
• Before altering the soil profile with on-farm clay pits, take the time to analyse the clay
and consider what other ameliorates may be a useful addition prior to incorporation.
• Electromagnetic (EM) and Gamma-radiometric (GR) are useful techniques to identify the
suitability of paddocks to different incorporation methods.
• Crop/pasture productivity can be greatly improved by reducing the non-wetting
characteristics of soils. In turn, greater yields also correspond with a reduction in soil
erosion due to better retention of plant residues.
