Evaluation of microbial inoculants pretreatment in straw and manure co-composting process enhancement

Popis výsledku v původním jazyce

Commercial microbial inoculants (MI) are usually inoculated during the co-composting of straw and manure to improve the compost process. In the present study, MI was prior used to pretreat straw before co-composting (MI pretreated) and compared with a treatment with inoculated MI during the cocomposting (MI inoculated) as well as a treatment without MI utilization (CK). Compared with the CK, MI utilization (MI inoculated and MI pretreated) significantly improved the compost maturity index of C/N (Sig. values 0,016),Cwater-soluble (organic)/N-organic (Sig. values 0,000), EC (Sig. values 0,043), and GI (Sig. values 0,009), as well as increased the final products total nutrient content by 4-13%.The MI pretreatment disrupted straw structure and enhanced lignocellulose degradation before co-composting as shown by a decreased straw cellulose content by 8-18% and hemicellulose content by 20-23%. However, no noticeable difference was found in the maturity index between MI pretreated and MI inoculated treatme
