“…The changes in the composition of the residue-assimilating microbial community are affected by the differences in nutrient content between NPK and NPKM soils (28,46) as well as by organic matter availability. The modification of the microbial community by fertilization can be direct (addition of microorganisms living in manure) (47) and indirect, including the following methods: (i) by improving the pH buffering capacity through manure application (48, 49), (ii) by addition of diverse available organic compounds or nutrients with manure, (iii) by (74,99).

Decomposition of crop residues in soil is mediated by microorganisms whose activities vary with fertilization. The complexity of active microorganisms and their interactions utilizing residues is impossible to disentangle without isotope applications. Thus, 13 C-labeled rice residues were employed, and DNA stable-isotope probing (DNA-SIP) combined with high-throughput sequencing was applied to identify microbes active in assimilating residue carbon (C). Manure addition strongly modified microbial community compositions involved in the C flow from rice residues. Relative abundances of the bacterial genus Lysobacter and fungal genus Syncephalis were increased, but abundances of the bacterial genus Streptomyces and fungal genus Trichoderma were decreased in soils receiving mineral fertilizers plus manure (NPKM) compared to levels in soils receiving only mineral fertilizers (NPK). Microbes involved in the flow of residue C formed a more complex network in NPKM than in NPK soils because of the necessity to decompose more diverse organic compounds. The fungal species (Jugulospora rotula and Emericellopsis terricola in NPK and NPKM soils, respectively) were identified as keystone species in the network and may significantly contribute to residue C decomposition. Most of the fungal genera in NPKM soils, especially Chaetomium, Staphylotrichum, Penicillium, and Aspergillus, responded faster to residue addition than those in NPK soils. This is connected with the changes in the composition of the rice residue during degradation and with fungal adaptation (abundance and activity) to continuous manure input. Our findings provide fundamental information about the roles of key microbial groups in residue decomposition and offer important cues on manipulating the soil microbiome for residue utilization and C sequestration in soil. IMPORTANCE Identifying and understanding the active microbial communities and interactions involved in plant residue utilization are key questions to elucidate the transformation of soil organic matter (SOM) in agricultural ecosystems. Microbial community composition responds strongly to management, but little is known about specific microbial groups involved in plant residue utilization and, consequently, microbial functions under different methods of fertilization. We combined DNA stable-isotope ( 13 C) probing and high-throughput sequencing to identify active fungal and bacterial groups degrading residues in soils after 3 years of mineral fertilization with and without manure. Manuring changed the active microbial composition and complexified microbial interactions involved in residue C flow. Most fungal genera, especially Chaetomium, Staphylotrichum, Penicillium, and Aspergillus, responded to residue addition faster in soils that historically had received manure. We generated a valuable library of microorganisms involved in plant residue utilization for future targeted research to exploit spe-

“…Moż-na więc domniemywać, że zawartość węgla organicznego oraz wartość pH należały do głównych czynników determinujących poziom aktywności dehydrogenaz. Z rozważań Fuchs (2010) oraz Sundberg i in. (2004) także wynika, że aktywność metaboliczna mikroorganizmów zależy od wartości pH kompostowanych odpadów oraz rodzaju i zawartości materii organicznej w podłożu.…”

“…Composting is an aerobic process, during which a mixture of organic substrates is degraded by several microbial communities, transferring the organic matter into a stabilized endproduct (Insam and de Bertoldi, 2007), which represents a potential alternative to peat (Boldrin et al, 2009). Advantages of composts as ingredients of growing media include their environmental benefits, nutritional contribution, potential positive impact on soil microbiota, and suppressiveness against soil-borne diseases (Tejada et al, 2009;Knapp et al, 2010;Boldrin et al, 2010;Fuchs, 2010;Yogev et al, 2010;Tejada and Benitez, 2011). Potential limitations include high bulk density, salinity, residual phytotoxicity, pH and rate of residual degradation with time (Raviv, 2011).…”
