| Abstract | ||||
| The effects of different types of mole drains on some clay soil properties and wheat yield were tested in this study. The experimental studies were conducted in heavy clay soil. Moles were composed of 3 different materials; compost, sand and mixture of compost with sand (1:1). Two depths of moles (0.3 and 0.5 m) and three distances among moles (10, 15 and 20 m) were investigated in this work. The results indicated that: - The Piezometric head increases as the distance among moles increases and vice versa. At each mole spacing, the Piezometric head decreases as the time advances after irrigations. However, the 10 m mole spacing achieved the best significant results over the 15 and 20 m spacing. - The highest yield (2737 kg/fed) was obtained by using compost, 10 m distance among moles and 0.5 m moles' depth. - Decreasing distance among moles, increases yield, penetration resistance (PR), hydraulic conductivity (Kh) and infiltration rate. - Increasing mole depth, increases yield, (Kh) and infiltration rate while decreases (PR). | ||||
