The organic matter (%) was quantified through the loss-on-ignition method by following Wu et al. [39] (link). This method involves preparing the sample, extracting organic matter, and quantifying it through techniques such as gravimetric analysis or spectroscopy. The content of lignocellulose in each treatment was estimated. For that, hemicellulose in soil was determined by separate determination of neutral detergent fibers (NDF) and acid detergent fibers (ADF) [40] (link). Lignin was determined as Klason lignin using 72% (v/v) sulfuric acid [41] (link), while cellulose content was measured at 620 nm using anthrone reagent [42] (link).
