Claim:
An agricultural planting implement comprising: a frame adapted for movement over a field in a direction of travel; and a plurality of planting modules supported on said frame for planting seed into the ground at a desired row spacing, each planting module including: at least one sweep having a width greater than the desired row spacing, said sweep being operable to make an opening in the ground for the placement of seeds therein, said opening being defined by lateral sides of said opening; a seed placement mechanism operable to place seeds into two rows at the desired spacing adjacent the lateral sides of said opening; a fertilizer placement mechanism operable to place fertilizer into said opening substantially midway between said lateral sides of said opening; and a closing device trailing said seed placement mechanism and said fertilizer placement mechanism operable to cover said seeds and said fertilizer with soil displaced by said sweep; wherein said closing device includes a pair of press wheels mounted for rotation about non-parallel axes so that each said press wheel is angled with respect to said direction of travel; wherein said pair of press wheels is oriented in a rearwardly converging manner; wherein said closing device further includes an adjustment mechanism for varying the angle at which each respective said press wheel is oriented to the direction of travel; wherein said press wheels set seed depth.
