“…Studies have shown that the amount of clay and silt in rhizosphere soil might vary depending on the ploughing technique used [1]. Additionally, continuous use of fertilization might affect the physical structure of the soil [48]. In this study, rhizosphere soil clay and silt were influenced by the tillage method, fertilization, and their interaction (Table S1).…”

Cassava (Manihot esculenta Crantz) is mainly cultivated in marginal land in the south of China where seasonal drought stress occurs frequently and the soil becomes more compact year by year. The study aimed to explore the effect of Fenlong tillage (FLT) combined with nitrogen applications on cassava rhizosphere soil particle composition and fungal community diversity. Conventional tillage (CT) was set as the control. The results indicated that the contents of clay and silt of the cassava rhizosphere soil were influenced by the tillage method, nitrogen (N), and their interaction. There was no difference in the richness and diversity of rhizosphere soil fungal communities among all treatments in 2019, while the richness of FLT was lower than that of CT in 2020. FLT caused a stronger influence on the community structure of rhizosphere fungi than N applications in the first year. The differences in the community structure of all treatments were reduced by continuous cropping of cassava in the second year. The top 10 dominant rhizosphere fungi at the class level of cassava found in 2019 and 2020 were Sordariomycetes, Dothideomycetes, Eurotiomycetes, Agaricomycetes, Intramacronucleata, norank_p__Mucoromycota, unclassified_p__Ascomycota, unclassified_k__Fungi, Pezizomycetes, and Glomeromycetes, which had an important relationship with soil pH, activity of urease, available nitrogen, available phosphorus, organic matter, and clay. These results indicated that FLT created a better soil environment for cassava growth than CT, thus promoting the formation of more stable rhizosphere fungal community structures.

“…Similar results were obtained by Mühlbachová et al (2022), who achieved an increase in value up to 1.7-fold. In areas with scarce rainfall, soil conservation technologies are vital, as other types of technology cause soil desertification (Ruan et al, 2021).…”

“…According to J. Liebig's law, the yield of any crop is limited by the factor (moisture, heat, light, air, etc.) that is at a minimum, which is especially true for soil moisture (Donaldson et al, 2001;Zsembeli et al, 2019;Ruan et al, 2021).…”

“…It has been established that this parameter significantly affects the emission of C-CO 2 from the soil, directly affecting root and microbial activity and indirectly on the soil's physicochemical properties (Ruan et al, 2021;Tuba et al, 2021). The positive effect of soil organic matter (SOM) on the physical, chemical and biological soil properties has already been well described.…”

The yield of any crop depends on soil moisture. One of the moisture conservation technological methods is fallow in the form of soil mulch with a layer not exceeding a thickness of 5–6 cm. To create this, a harrow utilizing special working devices was designed. This paper presents the results obtained on the dynamics of changes in soil moisture in a fallow field treated with a new harrowing unit compared to a serial cultivator operating at a depth higher than 6 cm. It was observed that the soil moisture in the harrowed area of the fallow field was 1.4 times higher, while the moisture reserves were 2.2 times higher in contrast to the field with the agrotechnical environment, treated with the sweeps of a serial cultivator. The actual soil tillage depth uniformity reached with the new harrowing unit is higher in comparison to that of the basic cultivator unit because, according to the F-test, the dispersion of fluctuations in the field tillage depth by the former (0.64 cm2) is significantly less than that for the latter (3.24 cm2).
