Abstract

Soil compaction is one of the serious problems of many soils in different parts of the world. Extremely high energy is needed to eliminate the compacted soil layer which will greatly help root extension and tolerance to drought. Draft force is a significant parameter In order to evaluate the performance of the device to determine the required energy and to manage the soil compaction. In this research the experiments were carried out in a factorial arrangement based on randomized complete block design with three replications. The depth of work in four levels and width of the blade were also selected in four levels and within each experimental plot, draft force and cone index were measured. The results of analysis of variance showed that the main effects of the width of the blade and the depth of work with the interactions of the two-dimensional width in depth at the probability level of one percent on the draft force is significant. The results indicated that increasing depth of work increases the draft force. Increasing the width of the blade increases the drfat force due to the mechanical strength of the soil.
