“…Different plant species can influence microbiome composition and structure, and some species appear to have a much stronger association with specific microbes than others [ 19 , 20 ]. The effects of plant genotype on the rhizobiome have been reported in Arabidopsis , cucumber, bean, Brachypodium , maize, barley, and wheat [ 21 – 26 ], though the intra-specific genetic contribution to microbiome assembly is relatively low. Decades of research have shown that plant genotype/species and developmental stages impact the qualitative and quantitative composition of plant root exudates [ 21 , 27 – 30 ].…”

Background Microbes benefit plants by increasing nutrient availability, producing plant growth hormones, and protecting against pathogens. However, it is largely unknown how plants change root microbial communities. Results In this study, we used a multi-cycle selection system and infection by the soilborne fungal pathogen Rhizoctonia solani AG8 (hereafter AG8) to examine how plants impact the rhizosphere bacterial community and recruit beneficial microorganisms to suppress soilborne fungal pathogens and promote plant growth. Successive plantings dramatically enhanced disease suppression on susceptible wheat cultivars to AG8 in the greenhouse. Accordingly, analysis of the rhizosphere soil microbial community using deep sequencing of 16S rRNA genes revealed distinct bacterial community profiles assembled over successive wheat plantings. Moreover, the cluster of bacterial communities formed from the AG8-infected rhizosphere was distinct from those without AG8 infection. Interestingly, the bacterial communities from the rhizosphere with the lowest wheat root disease gradually separated from those with the worst wheat root disease over planting cycles. Successive monocultures and application of AG8 increased the abundance of some bacterial genera which have potential antagonistic activities, such as Chitinophaga, Pseudomonas, Chryseobacterium, and Flavobacterium, and a group of plant growth-promoting (PGP) and nitrogen-fixing microbes, including Pedobacter, Variovorax, and Rhizobium. Furthermore, 47 bacteria isolates belong to 35 species were isolated. Among them, eleven and five exhibited antagonistic activities to AG8 and Rhizoctonia oryzae in vitro, respectively. Notably, Janthinobacterium displayed broad antagonism against the soilborne pathogens Pythium ultimum, AG8, and R. oryzae in vitro, and disease suppressive activity to AG8 in soil. Conclusions Our results demonstrated that successive wheat plantings and pathogen infection can shape the rhizosphere microbial communities and specifically accumulate a group of beneficial microbes. Our findings suggest that soil community selection may offer the potential for addressing agronomic concerns associated with plant diseases and crop productivity.

“…Even in conditions when abiotic processes lead to the dominant loss of organic mass, oxidation to CO2 and other inorganic molecules is mainly the result of the activity of organisms in the soil. Decomposition organisms consist of a complex community of soil biota, including soil microflora and fauna [62]. Fungi and bacteria are ultimately responsible for the biochemical processes of decomposition of organic residues [63].…”

Harvest residues are parts of cultivated plants that remain on the plot after harvest or grazing. Decomposition of plant residues by microorganisms involves two simultaneous processes: mineralization and humification of carbon compounds. Decomposition processes depend on the type of plant residues, edaphic factors and residue management factors. Edaphic factors dominate in areas exposed to adverse weather conditions, while the type of plant residues largely plays the role of a regulator in favorable environmental conditions. Decomposition of plant residues takes place in two stages; phase I is relatively fast and depends on the initial nitrogen content, and phase II is relatively slow and is determined by the decomposition of lignins and phenols. In general, water-soluble fractions are degraded first, followed by structural polysaccharides, and finally lignin. Low winter temperatures and dry soil during the summer limit microbial decomposition, while microbial decomposition is greatest during the wet warm spring and autumn seasons.

To study the effect of soil cultivation and fertilizer systems on controlling weed abundance in short crop rotation. Methods. Field, laboratory. Results. The experiment was carried out in a long-term stationary experiment on slightly saline chernozem under the system of long-term short rotations in the zone of insufficient soil moisture of the LeftBank Forest-Steppe of Ukraine. The results of studies on the effect of soil cultivation and fertilization on the abundance of weeds in winter wheat crops in corn chain of short crop rotation are presented. It was determined that the monocotyledonous and dicotyledonous weeds prevailed at period of plants outcome in tube. The application of mineral fertilizers under winter wheat against the fond of the organic fertilizer system aftereffect (manure and post-harvest residues) significantly reduced weediness. A significant difference was observed when used combined tillage compared to plowing. Among the weed species, dicotyledonous prevailed. Conclusions. The use of combined tillage for winter wheat reduces the crops weediness on unfertilized fond in 3.3 times, on fertilizers fondin 1.9 times. As a result of fertilizers application to winter wheat, the abundance of weeds on the fond of 6.25 t/ha of manure + N45P45K45 and plowing decreased by 11.0 pc/m 2 , and forcombined tillageby 10.7 pc./m 2 compared to unfertilized background. Whereas against the fond of manure and postharvest residues weedinessof crops grown. The use of plowing for winter wheat in crop rotation increases the species composition of the weeds. Among the weed species, the most widespread are weevils (Polygonum convolvulus L.), middle-aged sprout (Stellaria media L.), field axes (Delphinium consolida). The use of plowing increased the abundance of cereals on unfertilized fond to 34.3 pc/m 2 represented by mouse gray (Setaria glauca L.), on the fond of the manure and postharvest residues aftereffectto 88.5 pc/m 2 . When plowing, the abundance of beardless beetle (Polygonum convolvulus L.) on the fond of manure application at dose 6.25 t/ha and directly under winter wheat N45P45K45, as well as for the application of 6.25 t/ha of manure + post-harvest residues + N45P45K45 was 5.7 and 2.0 pc/m 2 , reciprocally.
