| The increased use of machinery for farm operations has also increased the intensity of traffic on agricultural land. This has caused growing concern about the undesirable effects of soil compaction. Presently farmers' decisions about when to t raffick their lands are based entirely on their experience of the existing conditions. If new circumstances arise, the farmers are less able to make the correct decisions. This paper attempts to develop a more objective and reliable technique to predice trafficability in view of avoiding soil compaction. A field experiment was set up to establish what relationship, if any, exists between the resistance to cone penetration and soil water suction at two different levels of dry bulk densities. The results suggest that there is a strong linear relationship between those tow parameters in the range of -100 to -500 cm head of water. An increase in dry bulk density of 0.07-0.08 g/cm 3 does not affect the relationship. Due to unfavourable climatic conditions, data was unattainable at lower soil water suctions. In order to predict tra fficability, further investigation is required to obtain data at lower soil water suctions to validate this relationship. | |
