The effectiveness of soil mixing by tillage implements locations

To determine how lime, nutrients or other amendments are distributed through the soil after applicaiton with different mixing methods.

Key messages
  • Soil inversion with a mouldboard plough, rotary spader and one way plough created equally patchy soil.
  • The one-way plough created the most vertical redistribution of the surface 10 cm of soil.
  • At least ten soil samples are required to gain a reliable mean for soil pH after inversion.
