16. Cultivation
Soil should be well cultivated prior to fumigation. Form 1m wide raised beds
(200mm high) with 40‐50cm walkways between rows.
If using a mechanical lifter, make sure the beds have appropriate width and
sufficient headland space for turning machinery (at least 3m).
An ASA Lift model LB3 with a 28mm rubber encased web is proven for lifting
larger grade tubers >2‐3g).
