Topping is a process by which a mower or similar implement is used to "top", or remove, the aerial part of a crop, in order to prevent seed formation and distribution onto the soil. Typically, a set-aside cover crop is topped in July or August, to prevent seed production and subsequent soil contamination leading to germination and regrowth.
