Soil with poor structure are hard to dig and break down into larger dense blocks.
Greyish coloured soils and soils with rusty or grey coloured mottles are signs of poor drainage. The higher the clay content the more likely the soil is to be naturally poorly drained.
Effective drainage relies on good soils management, maintaining good soils structure may avoid the need for capital investment.
You can minimise soil damage by reducing:
- Field trafficking
- Machinery weight
- Tyre pressures
- Poaching of livestock
- Overworking of the seedbed
Winged subsoilers developed in the 1980’s shatter the soil much more effectively than conventional subsoilers.
It is best practice to use a depth wheel or rear packer roller to maintain a constant tine depth.
