Passive leaching by rainfall and snowmelt is a popular method to treat piles of spent mushroom substrate (SMS) before its reuse. During this field weathering process, leachate percolates into the underlying soils. A field study was conducted to examine the chemistry of SMS leachate and effects of infiltration. Two SMS piles were deposited (90 and 150 cm in height) over a Typic Hapludult and wea...

Potential toxic metal (PTE) accumulation in soil and water is one of the major sources food crop contamination. PTE remediation from can be enhanced by addition organic matter to growing media. An experiment was carried out investigate effect different amendments on PTEs pea plant grown mine degraded soils. Mining soils chromite (CM), soap stone (SSM), manganese (MM), quartz (QM) were mixed wit...

The quantity of biogas residues is continually increasing and causing a great threat to the environmental protection sustainable development bio-natural gas engineering. Thus, four (sewage sludge, SR; spent mushroom compost, MR; wheat straw, STR; distillers’ grains, DL) were collected prepare biochars at different temperatures (300 °C, 500 700 °C) in this study. functional groups, crystal struc...
