Spader and liming trials: did they mix? locations
Aims

To investigate a spader machine for lime incorporation.

Key messages
  • As to be expected, the highest rate of lime application (100 t/ha) had the greatest increase on pH, increasing pH by 1.5 units in the topsoil and 0.4 of a unit in the sub soil.
  • The spaded only treatments (no lime applied) also increased the pH by bringing up less acidic clay into the surface soil horizons.
  • The higher lime rate applications showed that the soil pH had been evenly increased through the profile,  demonstrating the ability of the spader to uniformly mix the lime to depth.
