Phosphorus foraging root growth of Brassica and buckwheat roots
In a nonallophanic Andosol with low available P content, lateral roots of Brassica plants and buckwheat roots show spectacular growth at the interface between a P fertilizer and the soil. Although we used dicalcium phosphate dihydrate (DCPD) suspended in alginate gel beads in the following photo, similar root growth was observed when polyolefin-coated monoammonium phosphate was used as a P fertilizer.
