“…In our study, the average AMF frequency (F) and intensity (M) of the agroecological tea roots were significantly greater than in conventionally managed tea plantations. This finding is similar to observations made by Wu et al (2020) who indicated that organic tea management significantly increased tea soil AMF contents, while Wang et al (2017) revealed that long-term application of chicken manure strongly modified tea soil fungal communities. Singh et al (2008) also showed that the average AMF frequency of roots collected from natural and cultivated tea plantations was 77.6% and 86.5%, and intensity was 11.3% and 23.9%, respectively.…”

“…Likewise, stimulation of AMF growth by the incorporation of different organic amendments such as rice straw and organic compost has been widely reported in other cultivars (Hammer et al, 2011;Qin et al, 2015). By contrast, numerous studies indicated that mineral fertilizers, especially N and P, adversely affected AMF growth in tea plantations (Toman & Jha, 2011;Wu et al, 2020), in arable soil (Lin et al, 2012) and in rotation system (Qin et al, 2015). It was reported that AMF prefers a near neutral or alkaline soil pH for optimal growth and are strongly correlated with phosphorus level in soil, therefore, intensive application of mineral fertilizers changed the soil pH and P volume in the rhizosphere, thus affecting AMF communities (Helgason & Fitter, 2009;Ma et al, 2021).…”

“…Previous studies have consistently reported serious degradation of soil health as the consequences of converting forestlands and grasslands to croplands (Berkelmann et al, 2020; Gholoubi et al, 2018; Yang & Zhang, 2014). Yet, how crop conversion affects soil health properties and which mechanisms are involved have received less attention and in the specific case of tea plantations, several studies showed the negative impacts of land conversion from forestlands or perennial croplands to tea cultivation (Gholoubi et al, 2018; Wu et al, 2020; Zheng et al, 2020). These studies, however, did not focus on tea soil fauna communities, root AMF, as well as tea productivity, quality and the economic value of the conversion.…”

Tea is a very important cash crop in Vietnam as it provides crucial income and employment for farmers in poor rural areas. Unfortunately, the dominance of long-term, conventional tea cultivation has caused severe soil health degradation and environmental pollution. At the same time, as tea production may provide a better net income compared with other annual crops such as rice and vegetables, farmers have been converting parts of their allocated land to cultivate tea plants. Little is known about the benefit of agroecological management as an alternative to conventional tea management practices, and thus, there is a need to understand how it can improve tea yields, quality and the livelihoods of the farmers. Conducted in Northern Vietnam from 2019 to 2022, this study examined the impacts of agroecological tea management practices on soil health indicators, tea yield and quality, and net income of tea farmers. We showed that agroecological management practices significantly enhanced soil organic matter by 0.8% and soil pH by 0.5 units on average. Conversely, conventional manage-

“…Multiple genera within the phylum Firmicutes are associated with properties related to plant growth promotion, biocontrol, and bioremediation (Chauhan et al, 2017;Naureen et al, 2017). S. guianensis significantly increased the relative abundance of Firmicutes, which has been shown to promote plant growth and inhibit soil pathogens, which may be one of the reasons for the significant increase in soil available phosphorus (Hashmi et al, 2020;Wu et al, 2020). The above discussion results showed that intercropping S. guianensis may be way to improve plant growth and soil phosphorus content, but to consider that it reduces soil bacterial diversity, which requires further observation.…”

Green manure intercropping is an agronomic management practice that effectively increases soil nutrients in understory and reduces weed population. However, the influence of different green manures on soil properties and soil bacterial community in litchi orchards in the tropical regions of China remains largely unknown. Here, we examined the effect of intercropping three leguminous green manure crops in litchi orchards of Hainan Province. No intercropping was used as the control. Different green manures increased the contents of different soil nutrients. For example, Desmodium ovalifolium increased the total nitrogen content by 7.93%; Grona heterocarpos increased the ammonium nitrogen content by 558.85%; and Stylosanthes guianensis increased the available phosphorus content by 1207.34%. However, intercropping with D. ovalifoliu and S. guianensis reduced the content of available potassium by 47.29% and 58.48%, respectively. The intercropping of green manure increased the abundance of several microbial genera, including Bradyrhizobium, Serratia, and Bacillus, which are known to facilitate soil nitrogen accumulation, plant growth, and phosphorus dissolution. Compared with no intercropping, the three intercropping treatments significantly improved the contents of soil ammonium nitrogen and soil available phosphorus in the litchi orchard. Therefore, intercropping with green manure crops in litchi orchards is an effective management measure; however, the choice of the green manure crop should be based on the soil conditions of litchi orchards.

Background and Aim: The availability of minerals in the soil affect the mineral content of mangrove leaves. This study aimed to determine the macro- and micromineral contents in the environment and mangrove leaves (Avicennia marina) as animal feed in the coastal areas of West Sumatra, Indonesia. Materials and Methods: In this study, soil, water, and mangrove leaves were extracted from the mangrove plant's environment. The mineral contents were determined using the atomic absorption spectrophotometer of Beijing Rayleigh Analytical Instrument Corporation (make and country of origin). The total phenol and tannin contents were determined using the Folin–Ciocalteu and hide-powder methods, respectively. Results: The mineral content of the soil affected the mineral content of the plants. The soil and leaves of A. marina in the Pariaman area were richer in terms of macro- and microminerals. The soil had pH value, organic carbon content, leaf nitrogen content, phosphorus, calcium, and potassium of 5.65, 4.21%, 3.39%, 0.17%, 1.99%, and 0.54%, respectively. A. marina leaves had a total phenol and tannin contents of 24.51 mg GAE/g check the unit and 4.09%, respectively. Conclusion: This research showed that the mineral content in the soil in several mangrove areas in West Sumatra has a positive correlation with the mineral content in the leaves of A. marina, which have a complete mineral content. Therefore, A. marina leaves could be recommended as a mineral source for ruminants.
