As the fertilizer dribbles down, the sweeps cover it with soil. The spoke wheel injector is a recently developed tool that holds promise for liquid applications. The spoke wheel injector can be pulled with a variety of equipment including planters and cultivators, or it can be mounted on a tool bar. The injector places fertilizer into the soil without disturbing the crop residue. Other equipment with promise for more accurate application are electronic monitors and controllers for sprayers and anhydrous applicators.
Monitors show application rates at all times.
Summary In summary, the fertilization decisions to be made for reduced tillage are how much to apply and how to apply it. The decisions should be based on good soil tests, reasonable yield goals, and personal preferences for equipment and procedures. Equipment is available for about any application system wanted. Always use it with proper safety equipment and precautions.
