Webb1 juni 2024 · In order to better analyze the change of soil state and soil structure, especially the broken state of the plough pan, 4 layers of soil were designed in the simulation according to the actual conditions of the field soil (Fig. 1). The dimensions of the field soil bin were 1200 Long (mm) × 600 Wide (mm) × 640 Deep (mm). WebbKey points. Deep ripping (deep tillage) involves the use of strong deep working tines that penetrate the compacted soil and mechanically break up and shatter the soil hard pan. The ripping tines must be able to penetrate just below the compacted soil layer. Soil must be moist enough to allow penetration of the ripping tines but not so moist ...
