“…This is in accordance with the findings of previous reports that tobacco production can modulate the characteristics of soil nutrients, resulting in an insufficiency of N, Zn, and Mn, while P and K cannot be fully utilized in soil 22 , 23 . Due to the differences in the biological characteristics of the crop itself and the cultivation techniques, agricultural production will have discriminatory effects on soil, including physical and chemical properties, nutrients, and the water contents, with subsequent effects on the succeeding crops 24 – 26 . Therefore, the effects of crop biomass, soil N availability, and nutrient absorption and residues of N, P, and K after the cultivation of different preceding crops could be significantly divergent 27 , 28 .…”

Plant–microbe interactions can modulate the plant metabolome, but there is no information about how different soil microbiomes could affect the sugarcane metabolome and its quality. Here, we collected soil and stalk samples from bitter sugarcane (BS) and sweet sugarcane (SS) to conduct chemical analysis, microbiome and metabolome analysis. Our data revealed lower species diversity in the BS group than in the SS group, and 18 discriminatory OTUs (relative abundance ≥ 0.01%) were identified. Sugarcane metabolomic analysis indicated the different abundances of 247 metabolites between the two groups in which 22 distinct metabolites involved in two flavonoid biosynthesis pathways were revealed. Integrated analysis between soil microbial taxa, stalk chemical components, and soil properties showed that the flavonoid content in stalks and the nitrogen concentration in soil were highly correlated with the soil microbiome composition. Bacteria at the genus level exhibited greater associations with distinct metabolites, and six genera were independently associated with 90.9% of the sugarcane metabolites that play a major metabolic role in sugarcane. In conclusion, this study provided evidences that the interaction between plant–microbiome can change the plant metabolome.

“…The different land use systems had a significant effect on SMBC and SMBN (Table ). The observed differences in MBC and nitrogen under the different cropping systems could be attributed to variable microclimates resulting from the differences in vegetation cover, topography, and actively growing vegetation, especially in the systems involving tree plantation (Tetteh et al, ). Our results showed that vegetation cover through increased tree population influenced both MBC and microbial biomass nitrogen in the soils.…”

“…The microbial biomass C:N ratio has often been used to describe the structure of the microbial community (Moor et al, ). This ratio estimated was used as an indicator of nitrogen supply ability and also to describe the structure and state of the microbial community under the different land use patterns (Tetteh et al, ). The low ratio indicates a higher proportion of bacteria, whereas high values suggest the predominance of fungi in microbial population (Campbell et al, ).…”

This study evaluated the impact of predominant land uses on the physico‐chemical and biological properties of soils along an altitudinal gradient in Indian Central Himalaya to enhance the scientific knowledge and identify suitable land use pattern. Soil samples were collected from six predominant agricultural land uses including (a) open cropland, (b) cropland with multiple tree species (C + mT), (c) cropland with single tree species, (d) crop near rhizosphere of trees, (e) home gardens (HGs), and (f) agriculturally discarded land (ADL). The physico‐chemical properties showed the significant differences with land use systems and altitude. Soil texture varied from sandy loam to clayey loam with altitude. The minimum bulk density and higher porosity were recorded for the HG system whereas water holding capacity, moisture, pH, C, oil carbon stock, N, soil nitrogen stock, and P in the C + mT system. Soil microbial biomass carbon (16–397 μg g−1) and soil microbial biomass nitrogen (28–68 μg g−1) were significantly higher in C + mT and lowest under open cropland. The highest microbial biomass was recorded in the lower altitudinal region of Tarai, and the lowest was recorded in the higher altitudinal region. Across the seasons, soil microbial biomass was maximum during the rainy season and minimum during the winter season. Interestingly, ADL also showed significant contribution in soil microbial biomass carbon and soil microbial biomass nitrogen and could be used for crop production in the future. This study concludes that good soil health, higher amount of microbial biomass, and better soil qualities occurred in tree planted soils than in open crop lands, mainly attributed to the greater availability of organic matter, litter diversity, and fine roots.

“…Intercropping is a traditional and efficient planting mode that can make full use of the advantages of time and space, reduce the loss of soil, water, light, fertilizer, and other resources, and increase diversity in crop production [1]. The research on intercropping patterns at home and abroad includes food crops and cash crops [2], green manure crops [3], medicinal crops [4], fodder crops, and so on [5,6]. Its advantages are reflected in increases in crop yields [7], suppression of weeds and insect pests [8], increases in unit land productivity [9], repair of soil pollution [10], and protection of the environment [11], all of which contribute to the development of modern agriculture.…”

The karst area in Southwest China is facing the challenges of environmental degradation and agricultural safety. Intercropping is a green and efficient planting mode that can make full use of the differences in crops’ physiological and ecological characteristics and land and climate resources while considering the environmental and yield benefits. This study selected five treatments: Salvia miltiorrhiza monoculture, Dactylis glomerata intercropped with S. miltiorrhiza, Cichorium intybus intercropped with S.miltiorrhiza, Trifolium repens intercropped with S.miltiorrhiza, and Lolium perenne intercropped with S.miltiorrhiza. Using one-way ANOVA, principle component analysis (PCA), and linear correlation analysis, we analyzed the changes in the soil physicochemical factors and the coupling relationship between them in the intercropping mode. The results showed that at different soil depths, the soil bulk density in the intercropping mode was significantly lower than that in the single cropping mode (p < 0.05), and the soil water content and total porosity were significantly increased (p < 0.05). There were no significant differences in soil pH among the five models (p > 0.05), the content of soil organic matter was significantly higher than that in the single cropping mode (p < 0.05), and the content of nitrogen and phosphorus also showed different changes. The correlation analysis showed that there was no significant correlation between the pH and soil physical properties (p > 0.05); bulk density and chemical properties were negatively correlated, while the soil water content, field water-holding capacity, and total porosity were significantly positively correlated with the chemical properties (p > 0.05). Therefore, it is suggested to strengthen the management of agricultural grass intercropping, improve soil pore structure, regulate the distribution of soil water and fertilizer, and improve the resilience of agricultural systems in the karst area of southwest China.
