Differentiation of soil compaction and cane stool damage

After harvesting in wet periods, yield reductions due to compaction and/or stool damage had been found to be up to 42 percent. The present study, conducted on a Mollisol which was furrow-irrigated before harvesting, revealed the followings: wheel passes confined to the inter-row for conventional wagons or dumpers reduced subsequent cane yield to a maximum of 10 percent, when running over the stools, yields were reduced by 21 and 45 percent respectively and passage of a grab loader resulted in little damage. Ameliorative cultivation of the ratoon crop did not lead to any increase in root proliferation or cane production. Ripping tines appeared to have a detrimental effect due to root pruning.
