dc.description.abstract | An investigation of soil compaction in the sugarcane
fields of Mumias Sugar Company by transport
vehicles was conducted between October, 1989 and April,
1990.
Studies were conducted for the establ ishment of
safe axle loads beyond which detrimental soi I
compaction would be induced. The treatment involved
running a loaded test vehicle in strips previously
chosen at random in a split-split plot experimental
design. Safe loads were established on a set critical
bulk density and by testing the level of significance
of the difference in induced soil compaction between
treated from non-treated sections.
It 'w as difficult to establish a critical bulk
density but the statistical approach produced real istic
results. The treatment loads were set slightly higher
than the average axle loads induced by trailers of
Mumias Sugar Company.
Single bundle and high capacity bin-type trailers
were found not to induce detrimental soil compaction.
Some nucleus estate trailers however caused significant
soil compaction particularly in lowland fields.
'Jorking under' soil mo Ls t.u re of 17 to 21" (wet
weight), safe loads were found to be payloads of about
9000 and 6770 kg carried by single bundle and nucleus
estate trailers (respectively) on 18.4x30 tyres. This
corresponded to ground pressures of about 150 kPa. | en |
