“…In recent years, legumes intercropping, green manure, and goat manure has been widely used in red soil acidity and fertility improvement, which has gradually become a hot spot [38][39][40][41]. Most of the previous studies have shown that legumes intercropping and manure are beneficial for improving soil fertility and increasing yield [42][43][44][45]. In this study, chlorophyll contents, sprouts lengths, biochemical components, and the weight of hundreds 20-Y tea plantation improved with the integrated use of green and goat manure.…”

“…In this study, chlorophyll contents, sprouts lengths, biochemical components, and the weight of hundreds 20-Y tea plantation improved with the integrated use of green and goat manure. These profitable effects may be due to the maintenance and improvements of pH [46][47][48], available nutrients status [40,49], Aluminum detoxification [45,50], stimulation of low molecular weight organic acid [51], and the improvement of microbial activity and community structure [52]. Leguminous green manure has nitrogen fixation ability, plays an important role in the soil nitrogen balance, and can increase the effectiveness of phosphate and some trace elements.…”

“…With its specific physiological activity, functional diversity, and other characteristics, it can promote the plant root nutrient absorption. The application of leguminous green manure in the tea garden has the ability to promote the degradation of plant litter, decomposition, and mineralization of organic matter [45]. Leguminous green manure has a positive effect on soil phosphorus uptake.…”

Tea is an economic shrubby plant in tropical and subtropical regions of the world. To obtain high yield in tea cultivation, chemical fertilizer application rates have generally been used. However, a large quantity of chemical fertilizer application in a long-term continuously ratooned and monoculture tea orchard can inevitably lead to soil acidification and a decline in fertility. Therefore, the restoration of soil fertility and the sustainable development of tea planting by organic ways are critical for the tea industry. In this study, field trials were conducted in the tea orchard that was continuously ratooned and mono-cultured for 20 years. Nitrogen fertilizer (NF), Laredo soybeans green manure (LF), and goat manure (GM) treatments were applied to restore optimum acidity, soil fertility, microbial activity, and the community structure of a long-term continuously monoculture tea orchard. This paper investigated that the pH value was increased from 4.23 to 4.32 in GM and LF, respectively. Similarly, the content of exchangeable acidity (EA) was decreased by 1.21 and 1.46 cmol·kg−1 in GM and LF, respectively. Available nutrient results indicated that the content of NH4+-N was increased by 3.96, 4.38, NO3−-N by 1.07, 2.16, AP by 3.46, 6.86, AK by 0.26, 0.3 mg kg−1 in GM and LF treatments, respectively. Enzyme analysis revealed that the activity of urease and sucrase was promoted by 7.98 mg·g−1·24 h−1 and 6.77 mg·g−1·24 h−1, respectively, in LF treatment. Likewise, the activity of acid phosphatase and polyphenol oxidase was sharply increased by 2.3 mg·g−1 h−1 and 63.07 mg·g−1 h−1 in LF treatments. Additionally, the activity of urease, sucrase, acidic phosphatase, polyphenol oxidase, and peroxidase were also significantly increased by applying GM treatments. Meanwhile, LF and GM treatments significantly improved soil microbial biomass as well as low weight organic acid content in degraded tea rhizosphere. Furthermore, high throughput sequence results illustrated that the relative abundance of Rhizobiaceae and Bradyrhizobiaceae families increased in LF and GM treatments, respectively, which are mostly a kind of nitrogen fixer and plant growth promoting bacteria. Taken together, the physiological traits of the new sprouts and the biochemical components of new tea leaves were also significantly improved by GM and LF treatments. From this study, it is concluded that LF and GM are good agriculture management practices, which promote plant growth, yield, and nutrient availability by maintaining and improving pH, enhancing available nutrients status, improving the secretion of low molecular weight organic acids, and balancing the microbial community structure in the long-term mono-cultured tea orchard.

“…As they cover an important part of the soil, intercropped plants produce more shade, keep soil humidity and create more buffer microclimatic conditions (Siles et al, 2010). It also improves both physical (porosity) and chemical soil properties (soil pH, enzymes) (Wang et al, 2015). In Parana State in Brasil, coffee was intercropped with the cultivation of legumes, especially Leucaena leucocephala L. (Fabales: Mimosaceae), which significantly increased the soil enzyme activity (urease, arylsulfatase and phosphatase) as well as the Carbon and Nitrogen mineralization rates (Balota & Chaves, 2010).…”

Intercropping is an agricultural practice consisting in planting two or several crops in the same field simultaneously. This production system appeared to offer an excellent several advantages. While intercropping has been widely practiced since ancestral times, there was a lack of data in Rwanda on the kind of intercrops mostly used and on farmers' perception of their utility and constraints. The main objectives of this work were (1) to assess the different food crops associated with coffee trees in Rwanda and (2) to determine the perception of farmers on the role of intercropping system. That was why a field survey was carried out between August 25 th , 2014 and February 28 th , 2015 in Kamonyi District of Rwanda. Seventy-five coffee producers were randomly selected and contacted to fill a questionnaire on their practices. The correlation between yield and pesticide application were performed using R version. The significance level P was set at 0.05. Results revealed that common beans (Pheseolus vulgaris L.) and soybeans (Glycine max L.) were the most coffee intercropped plants. It appeared that intercropping was practiced to ensure the production of staple crops beside coffee. Insecticide remained the main way to control coffee pests and there was thus an important work to find alternative solutions that are often ecologically non-disruptive. Plant breeders and extension agents should investigate plants that are suitable to intercrop with coffee trees in order to enhance the conservation agriculture.

“…Urease is involved in nitrogen (N) transformation as it helps in producing ammonium, which is the major N source for plant growth (Bachmeier et al ., ). Soil phosphatase is closely related to the transformation of phosphorus (P), which assists soils to catalyse organic P into inorganic P (available to crops) (Liang et al ., ; Wang et al ., ). In addition, catalase is an important oxidoreductase participating in energy conversion, which promotes the decomposition of hydrogen peroxide to water and oxygen, thus reducing the toxic effects on organisms (Brzezinska et al ., ; Zhang et al ., ).…”

Fusarium wilt disease is one of the most serious soil-borne diseases in banana orchards worldwide. Some soils are suppressive to Fusarium wilt, although the mechanisms are still unclear. In this study, two typical banana-growing soils (ultisol and inceptisol), which were either suppressive or conducive to Fusarium wilt, were collected from Hainan, China. Particle size distribution, pH values, electrical conductivity (EC), enzyme activities and microbial polymerase chain reaction amplification of the soil samples were analysed. The suppressive soils had significantly more >2 and <0.053 mm aggregates than the conducive soils. In addition, the suppressive soils had a comparatively even size distribution within the range of 0-0.25 mm. Total carbon, total nitrogen and soil enzyme activities in the aggregates of suppressive soils were also significantly higher than those in the conducive soils. For example, soil invertase activities in the >2 mm aggregates were 7.9-11.9 and 3.2-3.3 mg/g for the suppressive and conducive soils, respectively. Furthermore, in situ EC can be applied as an indicator of the integrated contrast between the suppressive and conducive soils, and could be a new tool for monitoring soil-borne disease.
