0 present participle of earth
1 to put an earth (= wire) between a piece of electrical equipment and the ground:
There was not really a good positive correlation between the number of tippings and the frequency of earthing up.
Earthing up took place 1-3 times (usually twice), to increase yield.
Tipping may be less effective without earthing up as the extra stems and stolons produced will hardly produce extra tubers in that case.
Note that the agronomic purposes of tipping and earthing up are very similar and that both activities require a lot of labour.
Most respondents carried out the first earthing up in the first 45 days from planting, the second between 90-135 days and the third between 135-180 days from planting.
Two times earthing up is mostly practised.
Examination of the plant revealed a lack of proper earthing—a simple matter to the expert, but not to the unwary.
Further essential protection is provided by a proper earthing connection.
