Study on the physical properties of alternative growing media to LECA: Growing media composite made from HDPE/rice husk/calcium carbonate

Three categories of composite from the mixtures of high-density polyethylene (HDPE), calcium carbonate and rice husk were produced as an alternative growing media. Category A (HDPE/calcium carbonate), Category B (HDPE/rice husk) and Category C (HDPE/calcium carbonate/rice husk) composites were prepa...
