Tan K.S., . and Ooi L.H., . (2002) Impact of the mini-tractor grabber on soil-physical properties. [Proceedings Paper]
Abstract
This study investigated the changes in soil physical properties as a result of repeated passes of the mini-tractor grabber MTG on a Rengam soil series and a local alluvium soil under oil palm. A MTG carrying 1000 kg of fertilizer to simulate the normal MTG load was instructed to make 1 24 and 48 repeated passes on different plots. It was found that 24 continuous passes of the MTG caused a 15 increase in soil bulk density on Rengam soil and an 8 increase in local alluvium soil. Doubling the number of passes to 48 did not result in a further increase. The existing MTG tracks recorded almost zero soil infiltration but this was confined only to the tracks and not the surrounding area. Soil penetration resistance recorded on a Rengam soil series showed an increase with depth until a constant value was reached and the increase was more rapid on tracks with higher number of passes.
