“…Furthermore, the quantity of the fertilizers applied has a great potential to increase nitrate leaching (Yao et al, 2018;Delin and Stenberg, 2014) especially if it exceeds the uptake capacity of the plants (Guillard et al, 1995). However, in this study, this was the case only for chemical fertilizers but not for BRs as the sole nitrogen source.…”

“…The accumulation of nitrate in the soil depends greatly on environmental factors such as water availability, which dictates transformations and losses of nitrogen in the soil (Wang et al, 2006), while allowing N uptake by the vegetation (Yao et al, 2018). The results of the current study revealed the accumulation of nitrate in all three soil depths, when precipitation amounted to almost half (604 mm in 2015) of the annual rainfall for the region (1014 mm yr −1 ), under the application of chemical and combinatorial fertilizers (Fig.…”

To provide sufficient quantities of food and feed, farming systems have to overcome limiting factors such as the nutrient depletion of arable soils. Nitrogen being the main mineral element required for plant growth, has led to the extensive use of chemical fertilizers causing nitrogen pollution of the ecosystems. This field study investigates the use of biogas residues (BRs) as biofertilizers and their contribution to the mitigation of nitrate leaching in agricultural soils, while also demonstrating the polluting nature of chemical fertilizers. Nine different fertilization treatments classified in three schemes and two nitrogen doses were tested for three consecutive years on a grassland in the Walloon Region of Belgium. Residual soil mineral nitrogen, percentage contribution of treatments in residual nitrate and agronomic performance were assessed for each fertilization treatment. The results obtained showed significant differences on treatment and scheme level regarding nitrate accumulation in the soil, with chemical fertilizers posing the highest nitrate leaching risk. BRs did not cause nitrate accumulation in the soil, and were N rate and rainfall independent, while the chemical treatments indicated a cumulative tendency under high N rate and low precipitation. Forage yield did not demonstrate statistical differences on treatment and scheme level but varied with changing precipitation, while the maximum application rate suggested a

“…Diversified cropping systems, such as intercropping, relay intercropping, and crop rotation, provide an opportunity for achieving sustainable agriculture (Smith et al, 2013; Yang et al, 2019; Zhao et al, 2021). Legumes can relieve N requirement through biological N fixation, and provide N to subsequent crops, thus lowering synthetic N fertilizer input (Danga et al, 2009; Kumar et al, 2019; Yao et al, 2018; Guinet et al, 2020; Wang, et al, 2020a). However, some studies also showed that the grain yield of subsequent crops in legume‐based cropping systems is likely to be restricted due to higher soil water use during the legume growing season (Qin et al, 2018).…”

The introduction of legumes into the cropping system has been considered as an effective and alternative way to reduce nitrogen (N) input and greenhouse gas (GHG) emission, and boost system productivity. However, the productivity, water and N use, and carbon emission of legume‐based cropping systems in the North China Plain were not well‐documented. Here, a 2‐year field experiment was conducted to compare the yield, water and N use, and carbon footprint (CF) of summer peanut–winter wheat (PW) and summer maize–winter wheat (MW) cropping systems. Results showed that the experimental year significantly affected system productivity and water use efficiency of PW and MW. PW increased annual equivalent yield and water consumption by 10.1% and 12.9% in the first year (p < 0.05), compared with MW. Yet, PW decreased annual net income by 8.6% on average during the two experimental years. PW lowered annual N input by 12.1% compared with MW; however, no significant difference in apparent N use efficiency was found between PW and MW. Moreover, PW decreased its annual CF by 13.0%, which was attributed to the lower indirect GHGs emission from N input of summer peanut. In summary, PW showed considerable potential in reducing N fertilizer input and CF, with acceptable economic loss and water consumption in the North China Plain.

“…In a 2-year lysimeter study, Bergstrom and Kirchmann (2004) reported that the total cumulative N leached reached 73 kg ha −1 (red clover manure) and claimed that the water quality benefits of legume-based green manures should be evaluated with regard to the timing of N release and demand for N by the plant. However, Yao et al (2018) reported that growing legume green manures could maintain high crop yield and mitigate the environmental impact of residual nitrate by substantially replacing the synthetic N to avoid nitrate leaching to deeper soils. Further study is needed to clarify the relationship between the amounts of faba bean nutrients released into the soil and the amounts of nutrients leached to deeper soils.…”

This study was purposely designed to evaluate the potential of faba bean (Vicia faba) residues as green manure in a maize-faba bean rotation system. Seed germination test and pot experiments were conducted to measure the effects of aqueous extract on maize seed germination and the effects of residues on crop growth and soil microbial activities. Litterbag experiment was conducted to analyze the decomposition patterns of faba bean residues during maize growing season in a regosol soil. The faba bean was separated into roots, stems, leaves, aboveground parts, and whole plants. Seed germination and the lengths of radicle and plumule were lower than those of the control, particularly with 1% aqueous extract concentrations. Aboveground biomass of maize at heading stages was negatively reduced by whole plant, aboveground part, and stem, whereas positively increased by leaf. Faba bean residues varied in their influences on the contents of soil microbial nitrogen and carbon as well as enzyme activities, mainly attributing to their differences in nutrient quality and allelophathy. Faba bean residues showed a quick decomposition rate during the first 5 weeks and slightly decomposed thereafter. The amount of nitrogen (N) released into soil ranged from 3.74 kg N ha −1 in root to 34.67 kg N ha −1 from leaf in the first 5 weeks. Compared with other plant parts, there were more remaining residues in root and stem residues. These results suggest that different management strategies should be taken to balance their negative and positive effects when using faba bean residues as green manure.
