Abstract
A system and method are disclosed for cutting and increasing surface area of surface stubble material while contemporaneously cutting and aerating the soil. A discoidal coulter blade is configured with a plurality of circumferential teeth for cutting the surface stubble as well as reducing the downward pressure required for the blade to enter the type and depth of soil desired. The circular coulter blade is configured with a plurality of inserts oriented normal to the rotational movement of the blade as the blade cuts the soil. Each insert is shaped to aerate a specific type of soil anticipated by an operator. The inserts are positioned on the blade for desired impact with the soil and angled in placement on the blade to maintain the desired effect on the soil.
