Abstract:
1. A method of inserting granular material into the ground, comprising the steps of: creating a slit-opening in the ground, by drawing an angled knife blade, having a knife edge, through the ground; simultaneously depositing the material in the slit opening located behind the angled knife blade relative to a forward direction of travel; and engaging the angled knife blade at a depth of no more than about 15 cm vertically down into the ground, the angle knife blade including a body-over-surface above a body-under-surface that intersect at a line that defines a knife blade edge terminating at a tip at a lowermost and forwardmost point of the knife blade edge; wherein in a front elevation view looking in a direction in which the knife blade is drawn, the knife blade edge makes a side-slope angle of between 30 and 60 degrees relative to a horizontal, wherein in looking in a lateral elevation, the knife blade edge makes a pitch angle relative to the horizontal in the forward direction toward the tip, of between 30 and 60 degrees, and wherein each point of the knife blade edge in the ground is a lowest point of the knife blade so that the step of engaging the angled knife occurs lowermost in the ground at the knife blade edge aligned at the side-slope angle.
