| Abstract | ||||
| Seed-bed leveling is considered one of the most important agriculture operations. Success or fizzle of the following agricultural operations (sowing, harvesting, regularity of irrigation water) depend on the leveling degree. The expermintal results of this study suggest that the accuracy soil leveling destruct the soil structure. The fine aggregate specially (~ < 1 mm) move from the upper to the lower layer. They settle in the pore space specially the bigest. Consequently, the soil shear resistance increased about 26% and the required time for water intake rate increased between 2-7 times more than the leveled soil with traditional method. This results predict a negative influence on crop yield. | ||||
