In changing climatic conditions, the deep continuous loosening of soil developed by us can be the most effective alternative measure for expensive reconstruction of existing reclamation systems and, at the same time, an effective adaptive means for the accumulation of free soil moisture. The accumulation efficiency depends on the structure of the loosened soil. Due to the large amount of work with continuous deep loosening and the need to significantly change the structure of the soil, this process is quite energy consuming. Having determined the energy consumption for comminution the soil and comparing it with all the energy that is spent by the subsoiler on loosening the soil mass; we obtain its efficiency, the analysis of which, in turn, will allow us to evaluate the effectiveness of possible ways to improve the technological and economic performance indicators. Experimental research was planned and carried out on the basis of the methods of full factorial experiment, probability theory and mathematical statistics. The value of the proportionality coefficient of the Bond comminution hypothesis was experimentally established, which makes it possible to determine the energy saturation of technical means for loosening a certain soil mass. The obtained values were used to calculate the required minimum capacity of technical means for deep continuous loosening and basic tillage. It has been established that the required capacity of technical means for deep loosening is approximately 2 times less for sandy soil than for loamy soil. So, with a total working width of 2 m, a working speed of 2 m•sE−1 for deep loosening (by 0.75 m) and 4 m•sE−1 for the basic tillage (by 0.25 m), it is necessary to have the power of 170–240 kW of technical equipment for sandy soil and 390–440 for loamy soil.
