-Kristensen (2005) assessed the suitability of miscanthus clippings for use as a container substrate by measuring various physical properties of this material and other composted crop residues. Their ( Dresboll and Thorup-Kristensen, 2005 ) research did not include
fragmented into shorter chains or more oxidized components. Previous studies have demonstrated that crop residues from rice fields or composted rice hulls contain numerous secondary metabolites (see review by Rimando and Duke, 2003 ). The PBH used in this
