AB Soil compaction is a widespread problem limiting tree growth in urban areas. The Grow Gun and Terralift were developed to reduce soil compaction. Operationally both machines had advantages and disadvantages. In the soil, both machines created saucer shaped fractures. The area of Terralift fractures were two to four times larger than that of Grow Gun. Oxygen diffusion was improved only at the fracture line. Neither machine reduced soil bulk density.
