“…Tea (Camellia sinensis) belongs to perennial evergreen woody plants and is widely distributed in tropical and subtropical regions [1,2]. Previous research has reported that tea plantations could improve biological properties and enhance the content of SOM and nutrients, microbial basal respiration, biomass carbon and N in soil [3][4][5][6]. However, long-term tea monoculture can decrease the metabolic quotient, microbial diversity, and beneficial bacteria [2,7,8].…”

During tea cultivation, diverse agroforestry is an important and established intercropping measure, with most studies concentrating on ecological service provision and economic returns. However, the response of soil nutrients and microbial community structures in long-term tea plantations with diverse agroforestry intercropping systems is poorly understood. In the present field study (2015), three intercropping agroforestry-tea patterns (Osmanthus-Tea (OT), Michelia-Tea (MT), Osmanthus-Michelia-Tea (OMT)) along with a study control (C) were examined in terms of these two knowledge gaps. Results showed that, in terms of tea cultivation, the OMT system is more suitable than the OT and MT systems. The OMT system significantly increased the total nitrogen (TN, 16.4%), total potassium (TK, 10.5%), available nitrogen (AN, 14.2%), available phosphorus (AP, 26.7%) and soil organic matter (SOM, 28.9%). The OMT system increased phylum Firmicutes and Bacteroidetes abundance by 35.8% and 9.6%. In addition, the OMT system enhanced the abundance of class Bacteroidia (99.5%), Erysipelotrichia (96.9%), Clostridia (93.5%) and Actinobacteria (19.6%), respectively. In general, the phylum bacteria Proteobacteria, Firmicutes, Actinobacteria accounted for the largest proportion of bacteria in all three intercropping systems. In this study, the abundance of Firmicutes, Actinobacteria, Proteobacteria, and Bacteroidetes were positively correlated with AN, SOM and TP. The results of the present study will help to develop a better understanding of the benefits imposed by different agroforestry intercropping systems on nutrient dynamics and microbial structural diversity during tea cultivation.

“…For example, a study from a long-term apple orchard showed that organic carbon and available N and P content increased along the plant stand age [38]. The increase of soil organic carbon also was found in a long-term tea plantation [39]. Fertilization inputs can also improve soil nutrient availabilities [40].…”

Pomegranate (Punica granatum L.) is one of the most important fruit trees in semi-arid land. Previous studies were primarily focused on soil microbial community composition under different pomegranate plantation managements. However, soil microbial community composition under long-term pomegranate plantation has rarely been studied. We investigated pomegranate plantation along with an age sequence (i.e., 1, 3, 5, and 10 years after pomegranate plantation; abbreviated by P1, P3, P5, P10, respectively) in the Middle Yellow River floodplain. Our objectives were to address (1) variations of soil physicochemical properties and (2) changes in soil microbial community composition and the influential factors. The results demonstrated that the soil water content of pomegranate plantation decreased with the increase of pomegranate plantation stand age. Specifically, dissolved organic carbon, ammonium, and available phosphorus increased significantly with stand age both at 0–10- and 10–20-cm soil depths. The P10 had the highest microbial phospholipid fatty acid (PLFA) profiles, including fungi, bacteria, Gram-positive bacteria, Gram-negative bacteria, and arbuscular mycorrhizal fungi. The ratio of fungal PLFAs to bacterial PLFAs increased and the ratio of Gram-positive to Gram-negative bacterial PLFAs decreased along the pomegranate plantation stand age. Dissolved organic carbon was the most important influential factor among the studied variables, which explained 42.2% variation of soil microbial community. In summary, the long-term plantation of pomegranate elevated soil microbial biomass and altered microbial community composition.

“…The physical and chemical properties of the soil in tea gardens after undergoing years of plantation are gradually transformed, and the unique eco-environment in the soil will be generated accordingly thanks to the unique biological features of tea plants [ 25 , 26 ]. Current research on how to reduce soil nutrient degradation in tea gardens using different tea plant varieties is relatively lacking, but is very important to ensure the green, healthy, and sustainable development of tea plantations.…”

Tea plants are widely planted in tropical and subtropical regions globally, especially in southern China. The high leaching and strong soil acidity in these areas, in addition to human factors (e.g., tea picking and inappropriate fertilization methods) aggravate the lack of nutrients in tea garden soil. Therefore, improving degraded tea-growing soil is urgently required. Although the influence of biological factors (e.g., tea plant variety) on soil nutrients has been explored in the existing literature, there are few studies on the inhibition of soil nutrient degradation using different tea plant varieties. In this study, two tea plant varieties with different nutrient efficiencies (high-nutrient-efficiency variety: Longjing43 (LJ43); low-nutrient-efficiency variety: Liyou002 (LY002)) were studied. Under a one-side fertilization mode of two rows and two plants, the tea plant growth status, soil pH, and available nutrients in the soil profiles were analyzed, aiming to reveal the improvement of degraded soil using different tea varieties. The results showed that (1) differences in the phenotypic features of growth (such as dry tea yield, chlorophyll, leaf nitrogen (N), phosphorus (P), and potassium (K) content) between the fertilization belts in LJ43 (LJ43-near and LJ43-far) were lower than those in LY002. (2) RDA results showed that the crucial soil nutrient factors which determine the features of tea plants included available P, slowly available K, and available K. Moreover, acidification was more serious near the fertilization belt. The pH of the soil near LJ43 was higher than that near LY002, indicating an improvement in soil acidification. (3) Soil nutrient heterogeneity between fertilization belts in LJ43 (LJ43-near and LJ43-far) was lower than in LY002. In conclusion, the long-term one-side fertilization mode of two rows and two plants usually causes spatial heterogeneities in soil nutrients and aggravates soil acidification. However, LJ43 can reduce the nutrient heterogeneities and soil acidification, which is probably due to the preferential development of secondary roots. These results are helpful in understanding the influence of tea plant variety on improving soil nutrients and provide a relevant scientific reference for breeding high-quality tea varieties, improving the state of degraded soil and maintaining soil health.
