The invention provides a finger wheel adapted to follow behind and/or beside a furrow opener at varying angles to the vertical and to the direction of travel. The finger wheel is useful for covering a furrow with loose soil to retain gaseous material such as anhydrous ammonia in the soil. The finger wheel is also useful for removing dry soil from the top of a seed furrow to reduce the effective depth of seeding and improve emergence. Also provided are a gaseous material injector and seeding apparatus using a known double inclined disc in combination with the finger wheel.
