1. The effectiveness of soil mixing by tillage implements Craig Scanlan, Steve Davies, Damian Priest and Gavin Sarre.

2. Mixing Burial of surface layer Should soil mixing guide my choice of implement ? Loosening soil Seedbed

3. Measuring soil mixing required a new method. 1 2 34

4. Redistribution of soil by tillage implements

5. Colour blobs can be used to measure mixing efficiency. Low mixing efficiency High mixing efficiency

6. Inverted soils were equally mixed (patchy).

7. More samples are required for a reliable pH mean after soil inversion.

8. Control Rotary spader Mouldboard plough

9. A model to predict soil profiles after inversion and lime or clay application.
