“…The results showed intercropping with turmeric or ginger did not change the dominant phyla in the microbial community, but did significantly change the abundance of a number of different microbial species ( Figures 6 , 7 ). The dominant microbial phyla, such as Actinobacteria, Verrucomicrobia, Acidobacteria, Bacteroidetes, Mortierellomycota and Glomeromycota, were similar to those reported by previous studies ( Liu et al, 2014 ; Chen L. et al, 2020 ; Chen P. et al, 2020 ). Interspecies interactions may affect the abundance of some soil microbial populations, but they do not affect population diversity ( Li et al, 2018 ; Yu et al, 2019 ).…”

Continuous cropping (CC) restricts the development of the medicinal plant cultivation industry because it alters soil properties and the soil microbial micro-ecological environment. It can also lead to reductions in the chemical contents of medicinal plants. In this study, we intercropped continuously cropped Pogostemon cablin (patchouli) with turmeric or ginger. High-throughput sequencing was used to study the soil bacteria and fungi. Community composition, diversity, colony structure, and colony differences were also analyzed. A redundancy analysis (RDA) was used to study the interactions between soil physical and chemical factors, and the bacteria and fungi. The correlations between the soil community and the soil physical and chemical properties were also investigated. The results showed that intercropping turmeric and ginger with patchouli can improve soil microbial abundance, diversity, and community structure by boosting the number of dominant bacteria, and by improving soil bacterial metabolism and the activities of soil enzymes. They also modify the soil physical and chemical properties through changes in enzyme activity, soil pH, and soil exchangeable Ca (Ca). In summary, turmeric and ginger affect the distribution of dominant bacteria, and increase the contents of the active ingredient in patchouli. The results from this study suggested that the problems associated with continuously cropping patchouli can be ameliorated by intercropping it with turmeric and ginger.

“…At the level of phylum, ecological restoration did not change the dominant phyla of the soil bacterial community, but their relative abundances were significantly altered ( Figure 2B and Supplementary Figure S2). The dominant bacterial phyla, including Proteobacteria, Actinobacteria, and Acidobacteria, were in line with those in previous studies (Liu et al, 2014;Ding et al, 2016;Chen et al, 2020). Compared with the BL community, the relative abundance of Proteobacteria increased by 30.42%, whereas that of Actinobacteria decreased by 12.36% in the AL, and the relative abundance of Proteobacteria and Actinobacteria increased by 13.19 and 8.15% in the GL, respectively.…”

“…Although it takes time to build up nutrient levels, the OSA adoption still has a short‐run immediate, but potentially small, effect on soil nutrients and fertility. The positive relationship between OSA adoption and soil remediation has been reported in both short‐run and long‐run studies (Hoover et al ., 2019; Zhuang et al ., 2019; Chen et al ., 2020). The second pathway reveals that OSA adoption can influence net returns by affecting production costs.…”

“…Adolwa et al (2019) examined the impact of integrated soil fertility management (ISFM) in Ghana and Kenya and found that ISFM adoption could increase maize yields by 16-27 per cent. Organic soil amendments (OSAs) 1 such as organic fertiliser and farmyard manure have been identified as cores of soil-improving practices in land management (Xu et al, 2014;Hassen, 2018;Hoover et al, 2019;Zhuang et al, 2019;Chen et al, 2020), because OSA adoption helps build soil nutrition, increase organic matter and restore soil fertility on the degraded land. 2 For example, Xu et al (2014) found that adoption of organic fertiliser either individually or combined with chemical fertiliser could increase the soil nutrients and slow the rate of de-mineralisation.…”

This study examines the determinants of adoption of organic soil amendments (OSAs) such as organic fertiliser and farmyard manure and its impact on crop yields and net returns, using household survey data of 558 wheat farmers in China. We employ an endogenous switching regression model to account for selection bias stemming from both observable and unobservable factors. The empirical results show that household size, dependency ratio, machine ownership and non-paid labour are main factors that determine farmers' decision to adopt OSA, and the OSA adoption has a positive and statistically significant impact on wheat yields and net returns. In particular, the treatment effects of OSA adoption are to increase wheat yields and net returns by appropriately 22 and 24 per cent, respectively. Moreover, disaggregated analysis by farm size reveals that large-scale households tend to obtain higher wheat yields and net returns than their small-scale counterparts.
