“…A similar trend was observable in the M variant, but not in winter oats (CC3). It must be mentioned that Chen et al. (2023) showed that the incorporation of different straw types—from wheat or maize, irrespective that both are Poaceae crops—has distinct effects on the fungal and bacterial communities in soil.…”

Cover crops play an important role in low-input cropping systems, increasing the use of agro-ecosystem services. Due to the lack of information about the impact of cover crops and bio-fertilizers on popcorn maize (Zea mays everta Sturt.) growth and yield quality, especially the popping volume and nutritive quality, such as concentrations of protein and mineral elements, this research aimed to provide essential information. The interrelation between popcorn maize productivity and quality with important groups of soil microorganisms presents additional novelty. The results demonstrated that field pea is a beneficial cover crop, especially when combined with a bio-fertilizer, supporting the accumulation of maize biomass, chlorophyll, yield potential, and the concentrations of protein, Ca, Mg, Fe, and Zn. In addition, field pea residues promoted N-fixing bacteria, and the number of total microorganisms, especially actinomycetes and decomposing bacteria, which could promote nutrient uptake and grain quality. Residues of cover crop mixtures, common vetch + winter oats and field pea + winter oats, promoted the total number of microorganisms in the soil, and up to the end of vegetation, a greater number of decomposition and ammonification microorganisms were found, especially when the bio-fertilizer was applied, which consequently could support greater maize biomass. Popping volume, as a main trait of popcorn maize, had the highest value in the common vetch + winter oats variant, supporting again the statement that quality traits could be enhanced in sustainable production. Unlike living cover crops, mulch mainly affected soil microbial communities and promoted the development of actinomycetes and cellulolytic microorganisms during the growing season. The results of this research could contribute to the development of sustainable popcorn maize production for improved grain quality. They could also serve as a basis for isolating beneficial soil microorganisms to develop new bio-fertilizers that could improve maize production in synergy with cover crops.

“…1), which was consistent with the pattern of labile C content in organic amendments (Table 1). It can be concluded that the labile C component in manure and manure biochar is the initial source of increasing SOC content (Chagas et al, 2022;Chen et al, 2023). Chen et al ( 2023) also stated that most of the C in biochar is stable and cannot be converted into SOC in a short time.…”

The influence of earthworm activity on soil carbon (C) dynamic may be dependent on raw or char material additions in soil. The purpose of this study was to investigate the effect of cow manure or cow manure biochar addition and its interaction with earthworm on soil organic C (SOC), labile C fractions and β-glucosidase (βG) activity in a calcareous soil of semi-arid region. For this purpose, the soil was amended with cow manure and its biochar in 4 levels (0, 1, 2 and 5%) in the absence and presence of earthworm (Eisenia fetida). The treatments were then incubated for 30 and 90 days. The addition of amendments increased the content of SOC, particulate organic C (POC), microbial biomass C (MBC) and βG activity. The increase of the parameters was greater with manure than with biochar addition. Water soluble C (WSC) and permanganate oxidizable organic C (POXC) were increased by the addition of all rates of manure and 1% of its biochar but decreased by the addition of 2 and 5% of biochar to soil. The results showed an increasing effect of earthworm on SOC content, labile C fractions (especially MBC) and βG activity but its effect was not dependent on amendment additions (P>0.05). Overall, short-term manure application in soil seems to be an appropriate management practice for enhancing soil C storage than biochar. But since manure biochar contained more recalcitrant C than manure, a C sequestration in biochar-amended soils may happen in a longer time. Therefore, a long-term functioning of biochar on soil C pools needs to be further investigated.
