文摘

After 20-years of TSS application to Mediterranean soils, soil enzyme activities and C and N contents are increased. The studied doses of TSS induce GHG fluxes, change soil microbial structure and cause crop lodging. The application of TSS with urea induces carbon sequestration and increases fertility, whilst maintaining GHG emissions. TSS application to soil is a viable option for waste recycling as long as doses remain rational.
