“…S release initially increased due to vermicompost amendment, but with the advancement of time S release decreased compared to control soil. This might be due to a decrease in redox potential for prolonged soil inundation [83]. Vermicompost amendment also further decreased the redox potential of soil due to having a lot of labile organic matter in vermicompost [84].…”

Although its mechanism of action, particularly under wetland condition, is not clearly understood, vermicompost, a good source of humus and plant nutrients, has been used as organic manure in many parts of the world in order to increase crop production. Here, an anaerobic incubation study and a field study were conducted to observe the nutrient release pattern from vermicompost and its influence on performance and nutrient uptake in wetland rice. Two contrasting soils, viz. highly weathered terrace soil and very young floodplain soil, were subjected to anaerobic incubation, while the field trial was conducted in the terrace soil with control (no amendments), mineral fertilizer, vermicompost (10 t ha−1) + mineral fertilizer, cow dung (10 t ha−1) + mineral fertilizer, vermicompost (20 t ha−1) + mineral fertilizer and vermicompost (local farmer’s practice) + mineral fertilizer treatments. Results showed that there were significant increases in nitrogen (N) and phosphorous (P) release in floodplain soil but not in terrace soil, suggesting that nutrient release from vermicompost is soil-dependent. The performance of Boro rice in terms of yield and yield attributes improved significantly in the case of the integrated application of vermicompost with mineral fertilizer. Specifically, combined application of mineral nutrients and vermicompost (10 t ha−1) significantly increased grain yield by 25% compared to the control treatment. We believe that this occurred due to an improvement in supply and subsequent uptake of nutrients, especially N and P. Altogether, our results suggest that vermicompost could increase crop performance under field conditions, and, although these effects may not be significant in short-term incubation studies, they may be even larger in floodplain soil.

“…Rhizosphere N-fixing bacteria have a higher N-dissolving ability under water shortage conditions, which is an approach to enhance plant growth ( Knoth et al, 2014 ). Meanwhile, one can change the process of plant carbon assimilation, distribution, and deposition in the rhizosphere ( Holz et al, 2018a ), as well as the regulation of N mineralization ( Akter et al, 2018 ). Detailed practical cases of water management with regard to the microbiome and production are discussed in Section “Microbial C ommunity.”…”

As natural agroecology deteriorates, controlled environment agriculture (CEA) systems become the backup support for coping with future resource consumption and potential food crises. Compared with natural agroecology, most of the environmental parameters of the CEA system rely on manual management. Such a system is dependent and fragile and prone to degradation, which includes harmful bacteria proliferation and productivity decline. Proper water management is significant for constructing a stabilized rhizosphere microenvironment. It has been proved that water is an efficient tool for changing the availability of nutrients, plant physiological processes, and microbial communities within. However, for CEA issues, relevant research is lacking at present. The article reviews the interactive mechanism between water management and rhizosphere microenvironments from the perspectives of physicochemical properties, physiological processes, and microbiology in CEA systems. We presented a synthesis of relevant research on water–root–microbes interplay, which aimed to provide detailed references to the conceptualization, research, diagnosis, and troubleshooting for CEA systems, and attempted to give suggestions for the construction of a high-tech artificial agricultural ecology.

“…It has been determined that methanogenic bacteria in the soil can continue their function only when the redox potential is below a certain level of 200 mv (Minami, 1994;Wang et al, 1993). Since soils vary in buffering soil pH and Eh, therefore, soil type could also affect CH 4 production (Akter et al, 2018). Apart from the aforementioned aspects, soil environment (i.e., temperature and CO 2 concentration) has also been suggested to be associated with CH 4 production (Akter et al, 2018;Bhattacharyya et al, 2013;Li et al, 2004).…”
