“…Several studies have investigated the impacts of TWW reuse for the irrigation of several crops, including vegetables, on the uptake and bioaccumulation of potentially toxic elements in the edible parts of such plants, as well as on the microbial contamination of these tissues. Results revealed that high-quality tertiary treated effluent can be safely reused for the irrigation of vegetable crops either grown in an open field or under protected agriculture, including tomatoes [52][53][54], cucumber [55] and other vegetables [56][57][58].…”

Increasing agricultural systems’ resource efficiency is the key action for producing adequate food quantities in semi-arid Mediterranean regions while coping with water scarcity, environmental constraints and economic issues. Optimisation of irrigation and fertigation practices imposes different approaches, considering plant-water-soil relationships based on prevailing greenhouse microclimatic conditions, ensuring optimal production per drop of water and unit of fertiliser. In the content of "precision agricultural farming systems", nutrient uptake modelling, phyto-sensing, smart and sustainable technologies must be applied for monitoring and evaluating water and nutrients crops supply. However, in many cases, the use of irrigation and fertigation recipes given in the literature may not be compatible in the Mediterranean, as they usually originated based on northern European climatic conditions. The objective of this work is an attempt to understand various aspects of irrigation and fertigation management in vegetable fruiting crops such as tomato and cucumber towards nutrients and water resource sustainability in Mediterranean greenhouses.

“… Huang et al (2019) showed that the changes of the bacterial community distribution under farmland mulching practices were significantly related to the soil moisture, which varied significantly with a range of 9.8–17.3 between treatments. Obayomi et al (2020) indicated that there was a significant relation to soil pH with the soil bacterial richness and diversity under wastewater irrigation and plastic mulch. The higher correlation between soil microbial diversity and nutrient content, the more intense the competition between crops and soil microorganisms ( Miki, 2012 ).…”

The agricultural irrigation and fertigation systems have a non-negligible impact on the soil microenvironment in arid and semi-arid areas. Therefore, studying the processes and changes of soil microenvironment under different plastic mulch drip irrigation systems can reveal the “soil-microbe” mechanism and provide a theoretical support for the optimal irrigation and nutrition management of maize in the semi-arid area of Northeast China. Three treatments were used for this study in the semi-arid area of northeast China, namely; mulched fertigation system (MF), drip irrigation system (DI), and farmers’ practices system (FP). We used high-throughput sequencing to study the soil bacterial community structure targeting the 16S rRNA gene. The agricultural irrigation and fertigation systems significantly affected soil properties. MF significantly increased bacterial abundance and bacterial diversity and richness. Moreover, MF and DI markedly increased some relative abundance of beneficial bacterial. The bacterial network in MF was more conducive to the health and stability of the agroecosystem and the relationships among species in MF bacterial network were more complex. The agricultural irrigation and fertigation systems had indirect effects on community composition and bacterial diversity through soil organic carbon (SOC), ammonium nitrogen (${\mathrm{NH}}_{4}^{+}$-N), nitrate nitrogen (${\mathrm{NO}}_{3}^{-}$-N), pH, moisture, ${\mathrm{NH}}_{4}^{+}$-N and ${\mathrm{NO}}_{3}^{-}$-N had indirect effects on yield through bacterial community composition, bacterial diversity and bacterial abundance. These findings suggested that MF was the most effective treatment to improve soil bacterial abundance and diversity, and stabilize the functional quality of soil biological processes.

“…Collectively, research has indicated that irrigating with TWW: (a) increases bacterial diversity and reduces fungal diversity in soil ( Dang et al., 2019 ); (b) lowers the relative abundance of Actinomycetota (formerly Actinobacteria ) and increases the relative abundance of Gammaproteobacteria and Bacteroidota (formerly Bacteroidetes ) in root bacterial communities ( Frenk et al., 2014 ; Wafula et al., 2015 ; Zolti et al., 2019 ); (c) increases relative abundance of Gemmatimonadota ( formely Gemmatimonadetes), Bacteroidota (formerly Bacteroidetes) , and Pseudomonadota (formerly Proteobacteria ) ( Guo et al., 2018 ; Obayomi et al., 2020 ); (d) facilitates shifts in the composition of ammonia-oxidizing bacteria, with Nitrosomonas detected in TWW-irrigated soils, but not in freshwater-irrigated soils ( Frenk et al., 2014 ; Oved et al., 2001 ); and (e) increases Cyanobacteriota (formerly Cyanobacteria ) abundance ( Liu et al., 2018 ). These changes potentially have weighty implications on the ecology of microbial communities, for example, due to cyanobacteria's ability to fix atmospheric nitrogen ( Martins et al., 2011 ).…”
