Biochar mineral complex (BMC) can improve nutrient use efficiency (NUE) and reduce nutrient leaching, but the optimal application form and rate of application in soilless cropping systems remain unclear. This study evaluated co-applying BMC, either in solid form and placed to form a horizontal laminar layer approximately halfway up the potting media column, or as a liquid BMC suspension combined with reduced fertiliser rates in a protected ginger cropping system using pine bark potting media.
