Abstract: | Tillage is part of the overall process of the large agricultural business processes with process of mechanical energy input. The mechanical energy can be derived from the propulsion tractor couple with a hand rotary plows. Rotary plow is composed of the knives that can be mounted to beg on a shaft that rotates as it is driven by a motor. The purpose of this research is to know the size distribution of soil structure at three different speed rotary plows. This research uses descriptive methods of data analysis. This study used three treatments work speed tractor that were K1 = 396 rpm, K2 = 774 rpm, and K3 = 1180 rpm. From the result of soil tillage, soil samples was taken in 5 places for each treatment. The observations of rotary plow speed of 1180 rpm (K3), mean weight diameter obtained according to dry sieve diameter were 67.19, 15.96, 6.30 and 5.94 grams respectively. The highest agregate stability was generated by rotating the rotary plow at 396 rpm (K1) and 774 rpm (K2) with relatively the same stability index of 12.37 and 12.74, respectively. Based on total porosity produced, the best plant media was reached by rotating the rotary plow at 396 speed rpm (K1). |
