Dribbling or strip banding is a form of band placement that involves application of solid or fluid fertilisers in bands or strips of varying widths on the soil surface or on the surface of crop residues. Zones of high nutrient concentration are produced which improve nutrient use efficiency. Typically, the fertiliser material contacts 25% to 30 % of the soil surface. If these surface strip applications are followed by tillage, the concentration effect is diluted to something between broadcast application and deep banding where the concentrated zones remain intact.
