Introducing cover crops into maize rotation systems is widely practiced to increase crop productivity and achieve sustainable agricultural development, yet the potential for rotational diversity contribute environmental benefits in soils remains uncertain. Here, we investigated effects of different patterns on physicochemical properties, enzyme activities, microbial biomass communities from field experiments. Crop included (i) pure monoculture (CC), (ii) maize-garlic (CG), (iii) maize-rape (CR) (iv) maize-annual ryegrass one year (Cir1), two years (Cir2) three (Cir3). Our results showed that soil properties varied all patterns, with higher total available phosphorus concentrations CG CR lower organic carbon nitrogen maize-ryegrass rotations compared CC. Specifically, fertility was ranked as > Cir2 Cir3 CC Cir1. decreased activities but enhanced biomass.

Most notably augmented relative abundance bacteria, including Chloroflexi, Gemmatimonadetes Rokubacteria, not necessarily decreasing fungi like Basidiomycota, Mortierellomycota Anthophyta. Redundancy analysis indicated nitrate-N, ammonium-N had a large impact communities, whereas nitrate-N ammonium-N, P, greater effect communities. In conclusion, garlic, rape distinctly modify compositions. Thus, advocate garlic annual recommend two-year perennial Southwest China.

Study on the impact of hydraulic loading rate (HLR) on removal of nitrogen under low C/N condition by modular moving bed constructed wetland (MMB-CW) system

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 34, P. 103579 - 103579

Published: Feb. 19, 2024

Traditional constructed wetlands often exhibit low nitrogen removal efficiency when treating C/N wastewater, prompting the need for targeted technological innovation. Modular moving bed (MMB-CWs) have demonstrated superior performance, achieving over 15% higher TN compared to traditional subsurface flow wetlands, even without addition of carbon, further research is required fully understand operational effects different hydraulic loads and underlying mechanisms. To address this gap, contrast performance MMB-CWs with three substrate ratios 90% (unit A), 60% B), 30% C) was studied under conditions loading rates (HLRs). Results show that there are no significant differences in among systems at 250 mm/d 500 mm/d. NH4+-N NO3--N don't significantly decrease (p>0.05). High HLR leads lower effluent NO2--N concentrations. minimally affects CODCr removal, unit C exhibiting better resistance. Functional gene analysis reveals a minor role nitrification, emphasizing crucial anaerobic ammonium oxidation.
