Rice farming threatens freshwater resources, while also being increasingly vulnerable to drought due to climate change. Rice farming needs to become more sustainable and resilient to climate change by improving irrigation drainage systems. Small water bodies, used to store drainage water and supply irrigation in traditional rice farming systems have gradually been abandoned in recent decades. This has resulted in a higher water footprint (WF) associated with rice farming due to increased freshwater usage and wastewater release, also leaving rice production more vulnerable to extreme weather events. Here, we propose how protecting and reactivating small water bodies for rice irrigation and drainage can decrease rice production WF in China by 30%, save 9% of China’s freshwater consumption, increase irrigation self-sufficiency from 3% to 31%, and alleviate yield loss in dry years by 2–3%. These findings show that redesigning rice irrigation drainage systems can help meet water scarcity challenges posed by climate change.

Ferrous (Fe(II)) plays an influential role in production or consumption of N2O through chemical and biological pathways in paddy soil. Drying-wetting alternations can affect Fe cycling and the associated N2O emissions, however, the underlying microbial mechanisms remain largely unknow, particularly in plant system with the presence of roots. In this study, a laboratory experiment with four Fe(II) levels (0, 50, 150, and 300 mg Fe(II) kg-1 dry soil) was conducted to investigate the response of N2O emission and denitrifying genes to iron (II) supplement in root-affected zone and bulk region during wetting-drying alternation in paddy soils. The results showed that additional Fe(II) could decrease soil N2O emission, which mainly occurred during drying phase. Bulk soil possessed the higher N2O fluxes than those from root zone, but cumulative N2O (cumul-N2O) in bulk region was reduced by 55% in soils amended with 50 mg Fe(II) kg-1 dry soil, and by 82% with 150 mg Fe(II) kg-1 dry soil, which were larger than the reductions in root-affected soil. Supplemented Fe(II) resulted in the more sensitive increasing response of nosZ abundances than nir-type genes in drying period, especially in soil with low or medium Fe(II) additions. The high amount of supplemented Fe(II) (300 mg Fe(II) kg-1 dry soil) had a detrimental effect on nosZ-containing gene, leading to the lower reduction rate of cumul-N2O emission from bulk soil (31%), suggesting that the appropriate extra Fe(II) application into the soil helps N2O reduction during wetting-drying alternation. The copy number of nosZ genes in root zone were larger than those in bulk soil. In addition, according to cross-correlation analysis, the changes of nosZ-containing genes in root-affected soil occurred before variations of cumulative N2O data, demonstrating that root zone had the stronger capacity of N2O consumption effect, especially after addition of ferrous. These results indicated that response of nosZ abundance to Fe(II) supple

It is essential to reduce nitrogen losses and to improve nitrogen conversion during organic waste composting because of environmental protection and sustainable development. To reveal newly domesticated ammonifying microorganisms (AM) cultures on the ammonification and nitrogen-fixation during the composting, the screened microbial agents were inoculated at 5% concentration (in weight basis) into cow manure compost under five different treatments: sterilized distilled water (control), Amm-1 (mesophilic F1), Amm-2 (mesophilic Z1), Amm-3 (thermotolerant Z2), and Amm-4 (consortium: F1, Z1, and Z2), and composted for 42 days. Compared to control, AM inoculation prolonged the thermophilic phases to 9–19 days, increased the content of NH4+-N to 1.60–1.96 g/kg in the thermophilic phase, reduced N2O and NH3 emissions by 22.85%–61.13% and 8.45%–23.29%, increased total Kjeldahl nitrogen, and improved cell count and viability by 12.09%–71.33% and 66.71%–72.91%. AM was significantly associated with different nitrogen and microbial compositions. The structural equation model (SEM) reveals NH4+-N is the preferable nitrogen for the majority of bacterial and fungal growth and that AM is closely associated with the conversion between NH3 and NH4+-N. Among the treatments, inoculation with Amm-4 was more effective, as it significantly enhanced the driving effect of the critical microbial composition on nitrogen conversion and accelerated nitrogen ammonification and sequestration. This study provided new concepts for the dynamics of microbial in the ammonification process of new AM bacterial agents in cow manure compost, and an understanding of the ecological mechanism underlying the ammonification process and its contribution to N cycling from the perspective of microbial communities. © 2023, The Authors.

Soil colloids have been shown to play a critical role in soil phosphorus (P) mobility and transport. However, identifying the potential mechanisms behind colloidal P (Pcoll) release and the key influencing factors remains a blind spot. Herein, a machine learning approach (random forest (RF) coupled with partial dependence plot analyses) was applied to determine the effects of different soil physicochemical parameters on mobilizable Pcoll content in three colloidal fractions (i.e., nano- (NP): 1–20 nm, fine- (FC): 20–220 nm and medium-sized colloids (MC): 220–450 nm) based on a regional dataset of 12 farmlands in Zhejiang Province, China. RF successfully predicted mobilizable Pcoll content (R2 = 0.98). Results showed that colloidal- organic carbon (OCcoll) and minerals were the major determinants of total mobilizable Pcoll content (1–450 nm);their critical values for increasing Pcoll release were 87.0 mg L–1 for OCcoll, 11.0 mg L–1 for iron (Fecoll) or aluminium (Alcoll), 2.6 mg L–1 for calcium (Cacoll), 9.0 mg L–1 for magnesium (Mgcoll), 2.5 mg L–1 for silicon (Sicoll), and 1.4 mg L–1 for manganese (Mncoll). Among three colloidal fractions, the major factors determining Pcoll were soil Olsen-P (POlsen;125.0 mg kg–1), Cacoll (2.5 mg L–1), and colloidal P saturation (21.0%) in NP;Mncoll (1.5 mg L–1), Mgcoll (6.8 mg L–1), and POlsen (135.0 mg kg–1) in FC;while Mncoll (1.5 mg L–1), Alcoll (2.5 mg L–1), and Fecoll (3.8 mg L–1) in MC, respectively. OCcoll had a considerable effect in the three fractions, with critical values of 80.0 mg L–1 in NP or FC, and 50.0 mg L–1 in MC. It can be concluded that the P-carrying colloidal vectors in NP are mainly OC–Ca colloids;in MC, they are mainly Fe/Al/Mn-oxyhydroxide colloids complexed with OCcoll;in FC, both phenomena likely occur. © 2022, The Authors.

Salt marshes are important carbon sinks due to their high carbon sequestration capacity, but face the dilemma of extensive degradation. Biochar is an effective soil amendment to promote carbon storage. However, there are only a few observations on the salt marsh soil and a lack of evidence on factors influencing the performance of biochar. Therefore, we investigated the effects of different fresh and aged biochar (from Spartina alterniflora, corn straw, and Laminaria japonica) on the carbon fraction content and greenhouse gas (GHG) emissions of salt marsh soil with fresh allochthonous organic matter (Enteromorpha prolifera) addition. After 60 days of incubation, soil total carbon (TC) and total organic carbon (TOC) of biochar treatments were significantly increased by 34.54–180.96% and 129.10–590.54%, respectively. After biochar application, TOC loss and global warming potential (GWP) were reduced by 67.29–124.33% and 4.91–123.24%, respectively. The addition of biochar decreased the proportion of labile carbon (dissolved organic carbon (DOC) and microbial biomass carbon (MBC)) in the organic carbon pool by 61.92–86.15%. Biochar aged for a century still had the potential for carbon sequestration and emission reduction. Both fresh and aged biochar were found to reduce the abundance of some functional bacteria involved in organic matter degradation. These results suggest that biochar application in salt marshes may have a sustainable effect in promoting carbon storage and reducing GHG emissions. In addition, biochar had a protective effect on allochthonous organic matter and improved the stability of carbon pool in salt marshes. © 2023, The Authors. All rights reserved.

Lake restoration usually focuses on reducing external nutrient sources. However, when the sediment contains nutrients accumulated over multiple years, internal nutrient release can delay the restoration. In lake restoration and management, it is important to understand the dynamic relationship between nutrient concentrations in the lake and its internal and external nutrient sources. In this study, we quantified external nutrient inputs (from measurements) and compared them with internal sediment release (from simulation with the PCLake+ model). Additionally, we evaluated alterations in the internal nutrient release, lake nutrient concentrations, and algae biomass (chlorophyll-a) within the lake following varying degrees of reduction in the external nutrient load. The results demonstrate that PCLake+ effectively simulated the lake's nutrient concentration and phytoplankton biomass. Based on the PCLake+ estimates, internal nutrient loads accounted for 51% of the total nitrogen (N) and 80% of the total phosphorus (P) loadings in Lake Erhai in 2019. In 2020, the total contribution was 43% for TN and 72% for TP. Using our simulation, we reduced external nutrient inputs to 25%, 50%, 75%, and 99.99%. A 100-year simulation of the lake's ecological system indicated that the lake would initially exhibit a fast internal response and would reach equilibrium after eight years. The simulated P concentrations would take longer to reach equilibrium than N concentrations, probably due to the stronger binding characteristic of P. Although it is possible for internal nutrient loads to exceed external nutrient loads, water management should still prioritize controlling external loads due to the strong connection between external and internal nutrient loads. Our results show that reducing external nutrient loads eventually decreases internal loads. To meet the water quality target in the future, it is necessary to reduce external N and P inputs into Lake Erhai by at least 23% and 15%,

The technology of photothermal catalytic degradation of acetone and conversion of nitrogen monoxide (NO) not only reduces energy consumption compared to traditional thermal catalytic oxidation technology but also improves degradation efficiency, effectively overcoming the limitations of single photocatalytic or thermal catalytic technology. This paper aims to control the lattice oxygen activity and oxygen vacancy concentration of the catalyst by optimizing the manganese-cobalt (Mn-Co) molar ratio and modifying the catalyst with Ce doping, thereby enhancing its photocatalytic and thermal catalytic performance for the degradation of acetone and NO. At 240 °C, when the Mn-Co molar ratio is 4:2, the CoO x /MnO x @Fe 2 O 3 -2 catalyst exhibits good catalytic activity for both acetone and NO, with conversion rates of 52% and 63.8% for acetone and NO, respectively. Based on the optimization of the Mn-Co molar ratio, Ce was doped into the CoO x /MnO x @Fe 2 O 3 -2 sample using the co-precipitation method to synthesize samples with different Ce doping amounts. The sample of CeO 2 /CoO x /MnO x @Fe 2 O 3 -2-0.25 ( n Mn-Co : n Ce = 1:0.25) shows the highest catalytic performance compared with the other samples, with the conversion of acetone and NO reaching 60% and 70%, respectively, at 240 °C. Additionally, the intrinsic mechanism under photothermal synergy is based on the Mars-van Krevelen redox cycle theory.

Rainfall-runoff and water flooding are the driving mechanisms of agricultural nonpoint source pollution (ANPSP), but existing research has hardly focused on water level–driven ANPSP. Danjiangkou Reservoir, the second largest reservoir in China, was selected as the object of this study. The effect of water level–driven ANPSP on the concentration of reservoir ammonia was studied employing the methods of factor decomposition and multiple regression on a extensive time series data of reservoir ammonia, water level, rainfall, fertilizer usage, and inflow river ammonia. The factor decomposition extracted the seasonal variation and long-term trend from the time series data. The long-term trend revealed the reservoir ammonia peaked in 2011 and the inflow river ammonia peaked in 2012 (Han River) and 2013 (Dan River), which indicated the success of point source control in the past 15 years and the dominant role of ANPSP in the reservoir ammonia in recent years. With the long-term trend series, the multiple regression results showed that 56% of the variation of the reservoir ammonia concentration was due to the water level (standardized regression coefficient 0.422), fertilizer usage (standardized regression coefficient 0.522), and inflow river ammonia (standardized regression coefficient 0.219). However, the rainfall was insignificant. The predominance of water level and fertilizer usage in explanation of the reservoir ammonia variation indicated that water level-driven ANPSP was the primary factor influencing the reservoir ammonia. The reservoir ammonia showed no discernible seasonal differences, but the water level displayed significant seasonal differences. The effect of water level was primarily reflected in the long-term variation of ammonia concentration rather than the seasonal variation within the year. This study showed that when compared with rainfall-driven ANPSP, water level–driven ANPSP had a greater impact on the reservoir ammonia. Water quality protection shoul

Insights on anaerobic co-digestion of carbohydrate and protein at high load: synergy evolution and inhibition transfer mechanism

The anaerobic co-digestion (AcoD) of carbon-rich and nitrogen-rich substrates has significant synergistic effect in methane production, but its synergy mechanism is still unclear, which hinders the in-depth understanding of the synergistic effect in AcoD and the establishment of scientific proportioning rule based on organic components. This study determined the synergy evolution and revealed the two-way synergistic mechanism between carbohydrate and protein in AcoD system. The addition of certain protein can avoid the acidification of AD process with high-concentration carbohydrate by providing additional alkalinity to neutralize H + . However, the increased dosage of protein (≥60 %) would change the acid inhibition gradually to ammonia inhibition. The optimal dosage of protein was 40 % of carbohydrate with the highest methane conversion efficiency of 0.93, where that of carbohydrate mono-digestion was only 0.16. On the other hand, low proportion of carbohydrate can reduce ammonia inhibition during the AD process of high-concentration protein through promoting the conversion of free ammonia to ammonium ion, but the excessive addition (≥60 %) would significantly inhibit the volatilization of ammonia nitrogen and then aggravate the ammonia inhibition. The suitable dosage of carbohydrate was 40 %–50 % of protein with the optimal methane conversion efficiency of 0.68–0.71, where that of protein mono-digestion was only 0.55. These results provide a deep insight in the two-way synergistic mechanism between carbohydrate and protein in the AcoD process, and promote the concrete implementation of AcoD with multiple substrates.

Nutrient loading is the key cause of lake eutrophication, and exploring management options to reduce river export of nutrients to lake is crucial. By applying the MARINA-Lakes (Model to Assess River Inputs of Nutrients to lAkes) model to project river export of nitrogen (N) and phosphorus (P) to Lake Taihu by sources at the subbasin scale, we find that rivers are projected to export less total dissolved nitrogen (TDN), but more total dissolved phosphorus (TDP) to Lake Taihu in 2050. The critical nutrient loads (CNLs) may decrease by 25–53% by 2050 due to warmer climates, widening the gap between CNLs and actual nutrient loads. Improved nutrient management in agriculture and sewage systems is expected to reduce river export of TDN by 5–12% and TDP by 19–39% in 2050. However, this may not be sufficient to reduce future nutrient pollution below CNLs. Nature-based solutions, such as constructed wetlands, can keep future TDP below CNL in 2050, but reducing TDN pollution below CNLs will remain challenging. This study can contribute to formulating effective solutions to reduce nutrients and restore Lake Taihu's clarity.
