Air Injection Of Organic Material During Deep Tillage To Improve The Quality Of Reconstructed Soil

Deep tillage is widely used as a means of alleviating excessive soil compaction. There has been some concern that the voids created by deep tillage may collapse before a more natural soil structure develops, resulting in recompaction subsequent to deep tillage A laboratory investigation was conducted to determine the feasibility of pneumatically injecting organic material into the voids produced during deep tillage in order to prevent any significant recompaction from occurring. Various amendments were injected into the soil during laboratory tests using a small-scale ripping and injection system. Measurements were made of selected soil proper Pies to evaluate the feasibility of this method.
