A subsoiler is an implement for breaking up and loosening the soil. These activities are to facilitate the growth of the plant’s root system. Subsoiling lifts and shatters the hardpan, thus restoring the normal water-air proportions in the soil. This measure is used when the soil has dried, preferably immediately after harvesting. The unit can also be used to prepare the soil for planting shrubs, fruit trees and deep-rooted plants.
