Banding of fertiliser may restrict fixation of P by soils and thus improve P fertiliser use efficiency. Using pots that allow soil to be sectioned, we examined the effect of banding triple superphosphate (TSP), mono-ammonium phosphate (MAP), and di-ammonium phosphate (DAP) on canola (Brassica napus var. oleifera 'Karoo') growth and nutrition in P-fixing soils and the pattern of nutrient distribution from these bands.
