Abstract
Clay content is one of the parameters which affect the physical and mechanical properties of soil. In the formation of shallow mole drainage, the clay content will affect the mole, especially on soil deformation due to the tillage force. This study aimed to explore the effect of clay content on soil deformation in the mole drainage formation. The following parameters were used in approaching the soil deformation namely, the mole’s hole area (Al), the leg slot (Cl), the disturbed soil area (Tp), the surface area of soil fracture (Ap) and cracks in the leg slot wall (Pr). The results showed that the width of the mole’s hole area (Al) in the soil with clay content of 13.12% (TA), 41.17% (TB) and 53.63% (TC) were almost the same. They were TA = 7.03 cm2, TB = 6.98 cm2 and TC = 6.95 cm2. The width of mole’s hole area TA = 0.31 cm, TB = 0.35 cm and TC = 0.88 cm. The clay content influenced the disturbed surface area (Tp) and the surface area of soil fracture (Ap). The larger the clay content the soil had, the greater its Ap and Tp. The measurements showed that TC soil (0.0570 cm2/cm2) had larger Tp than that of TB soil (0.0283 cm2/cm2). The disturb surface area of TB soil was larger than that of TA (0.0087 cm2/cm2). The surface area of soil fracture of TC soil (32.2806 cm2) was larger than that of TB (24,3467 cm2). The surface area of soil fracture of TB soil was larger than that of TA (13.8000 cm2). The crack length of leg slot wall of each type of soil were subsequently TA = 0,5001 cm/cm2, TB = 0,3523 cm/cm2 and TC = 0,4141 cm/cm2. Keywords: clay content, soil deformation, mole drainage.
