Abstract:

Data was collected for single bundle and nucleus estate trailers aimed at selecting the trailer units that could safely travel in the sugarcane fields without causing detrimental soil compaction. The proportion of trailers carrying loads in excess of established safe axle loads was assessed. Over 60% single bundle trailers traveling in sandy loam and sandy clay loam fields were found not to induce detrimental soil compaction. Nucleus estate trailers, however, were sufficiently loaded to cause significant soil compaction. Working under soil moisture contents of 21.4–27.1% (dry basis), safe loads were found to be payloads of 64.9 and 46.1 kN carried by single bundle and nucleus estate trailers (respectively) on a single axle having two 10 ply 18.4×30 tires with an inflation pressure of 207 kPa.
