Identification and Quantification of Soil Compaction Due to Various Harvesting Methods—A Case Study

Abstract

SYNOPSIS World-wide literature has clearly documented the fact that soil compaction caused by wheel traffic has a negative effect on future site productivity. In spite of this evidence there remains a difference of opinion within the forestry community calling for more emphasis to be placed upon compaction research. Penetrometer soil strength is an experimental method currently being used to quantify the effects of wheeled movement on soil. The penetrometer soil-strength measurement is a fast, effective way of measuring the resistance the soil offers to potential root growth. The sandy soils of Zululand are susceptible to compaction and it has become increasingly important to determine its long-term effects on site productivity. This study on a Mondi Forest plantation attempts to identify and quantify the potential damages caused by wheeled traffic. Results show that harvesting planning and operations in future will have to consider the implications of compaction and plan and operate accordingly.
