Abstract:

In order to examine the impact of ferrous sulfate on the fungal community during the thermophilic phase of chicken manure composting, as well as the effects of the compost products on plant growth, chicken manure and rice straw were used as raw materials, with the control group being the heap without any exogenous additives and the treatment groups being the heap with 1% or 2% ferrous sulfate addition. The changes in the composition and structure of the fungal community, as well as the growth condition of pakchoi and its nutrient quality were monitored.It was shown that adding ferrous sulfate to chicken manure composting affected the structure of the fungal community during the thermophilic phase, enhanced the diversity of the fungal community, enriched most of the dominant fungi related to lignocellulose degradation, which was conducive to the efficient degradation of difficult-to-decompose organic matter in composting, and facilitated the composting humification process. Plant height, chlorophyll content, soluble protein content and soluble sugar content were significantly (P<0.05) higher in the treatment groups compared to the control group. The effect of compost product with addition of 2% ferrous sulfate was more pronounced.

Key words: chicken manure composting, ferrous sulfate, fungal community, pakchoi
