“…Figure 6 illustrated that soil microbial nitrification and the soil WC were the most important factors contributing to the increased N RE levels. This is similar to the findings of Tang et al (2022) and Takakai et al (2017). This indicates that the increase in fava bean N RE levels could be attributed to improved soil fertility and the promotion of microbial immobilization of bioavailable N in an aerobic environment during the dry season (Choi et al, 2001; Tang et al, 2022).…”

“…A large number of studies, including recently published literature, have confirmed the inconsistency of soil and crop yield responses to OSM under different cropping systems (Lan et al, 2022; Li et al, 2022; Liu et al, 2021; Xie et al, 2016; Zhang et al, 2018). Generally, this inconsistency may be attributed to the differences in (1) nitrogen requirements of the crops involved in the different studies (Yao et al, 2018) and (2) nitrogen transformation processes, which vary with the soil environment (Said‐Pullicino et al, 2014; Tang et al, 2022). The above discrepancies suggest that the crop type grown and soil environment greatly determine the effect of OSM on soil N pools and crop N utilization.…”

Organic substitution management (OSM) is critical for soil conservation and nitrogen efficiency. However, integrated assessment of soil quality and crop productivity under paddy‐upland rotation systems after OSM introduction is still lacking. Here, soil nitrogen‐related properties and crop nitrogen use efficiency (NUE) were evaluated in 2018, 2019, and 2020, based on a long‐term rice‐fava bean rotation experiment started in 2015. In comparison to chemical fertilization, OSM increased total soil nitrogen (TN) and available nitrogen (AN) by 13.1% and 13.8%, respectively, during the rice season, and by 16.3% and 15.9% during the fava bean season. However, NUE, nitrogen recovery efficiency (NRE), and nitrogen agronomic efficiency (NAE) all showed season‐specific responses to OSM. OSM decreased NUE, NRE, and NAE by 18.2%, 37.5%, and 26.2% in the rice season but increased by 8.0%, 231.0%, and 184.1% in the fava bean season. From the rotation system scale, there were no significant differences in NUE and nitrogen surplus between the treatments. We suggest that the differences in soil conditions and crop requirements between seasons play significant roles in the response of nitrogen accumulation and nitrogen utilization to OSM. Based on these differences, OSM achieves inter‐seasonal synergy in soil N pools and crop uptake, and results in yield stabilization and soil nitrogen accumulation. Because of its high capacity for improving soil quality while ensuring no yield reduction, OSM has the potential to curb regional soil degradation in paddy‐upland rotation areas where there is increasing demand for food and chemical fertilizers are currently abused.

“…The addition of organic fertilizer enhances

immobilization by slowly releasing mineral N from the decomposition processes, while facilitating the interaction between soil C and N cycles, thus significantly reducing N losses to the environment. Under the same N application rate in this study, the marked contrasting effects observed between total N and mineral N content suggested that manure input was favorable for N retention as complex organic forms ( Tang et al., 2022 ). Therefore, replacing part of chemical fertilizer with manure is an effective method to reduce inorganic N surplus observed in soil of conventionally excessive chemical N fertilization.…”

“…In recent years, studies on the application of organic materials in maintaining soil nutrient balance and reducing nutrient losses have been widely reported ( Steiner et al., 2008 ; Beesley et al., 2011 ; Zhang et al., 2018 ). Tang et al. (2022) found that a 50% substitution with pig manure increased the diversity of bacteria, the relative abundance of specific microbiota involved in N cycling, the amount of denitrifiers, and the proportion of N 2 O-reducers, which resulted in a 44% reduction in agricultural inputs and less environmental impacts per unit of product.…”

Organic manure has been proposed to substitute part of the chemical fertilizers. However, past research was usually conducted in regimes with excessive nitrogen (N) fertilization, which was not conducive to the current national goal of green and sustainable development. Therefore, exploring the potential of organic fertilizer substitution for mineral N fertilizer under regimes with reduced N inputs is important to further utilize organic fertilizer resources and establish sustainable nutrient management recommendations in the winter wheat (Triticum aestivum L.) – summer maize (Zea mays L.) rotation system in North-central China. In this study, a 4-year field experiment was conducted to investigate the effects of different chicken manure substitution ratios on crop yield, N recovery efficiency (REN), soil N and soil organic matter contents, to clarify the optimal organic substitution ratio of N fertilizer under reduced N application (from 540 kg N ha−1 year−1 to 400 kg N ha−1 year−1). Six substitution ratios were assessed: 0%, 20%, 40%, 60%, 80% and 100% under 200 kg N ha−1 per crop season, respectively, plus a control with no N application from chemical fertilizer or chicken manure. Results showed that the highest yield was achieved under the 20% substitution ratio treatment, with 1.1% and 2.3% higher yield than chemical N alone in wheat season and maize seasons, respectively. At the chicken manure substitution ratios of 20% in wheat season and 20%-40% in maize season, the highest REN reached to 31.2% and 26.1%, respectively. Chicken manure application reduced soil residual inorganic N with increasing substitution ratio. All organic substitution treatments increased soil organic matter and total N content. Implementing 20% organic substitution in wheat season and 20%-40% in maize season under the reduced N application regime in the North-central China is therefore recommended in order to achieve high crop yields and REN, improve soil fertility and enhance livestock manure resource utilization.

Wheat is a key cereal crop that is substantial to global food security. Fertilizers are crucial in wheat production and significantly impact the yield. This review aims to evaluate the effectiveness of inorganic, organic, and integrated fertilizers in terms of sustainable wheat production and economic and environmental benefits. For this review, we thoroughly examined 133 previous research findings. The results indicate that inorganic fertilizers play a vital role in improving wheat yield. However, continuous use of inorganic fertilizers pollutes the environment, affects beneficial microorganisms in the soil, and increases the emissions of greenhouse gases, consequently decreasing crop yield. Organic fertilizers enhance soil quality, which is critical for crop growth and development. However, a high concentration of methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) are emitted from organic fertilizers, but the CO2 emission rate is less than the sequestration rate. Integrated fertilizers trade off the drawbacks of both inorganic and organic fertilizers. Integrated fertilizers decrease nitrous oxide (N2O) and ammonia (NH3) emissions and carbon loss by 11%–24%, 13%–27%, and 18%, respectively, compared to the sole use of fertilizers. From the review analysis, the highest grain yield (4855 kg ha−1) and net benefit ($2836.66) are achieved by using a combination of 75% organic and 25% inorganic fertilizers at a rate of 120 kg N ha−1. Therefore, this combination is recommended for the users. Furthermore, a site‐specific approach research is needed on integrated fertilizers that simultaneously focus on economic and environmental profits. Also, there must be a policy that supports the farmers in teaching, training, and subsidizing them to adopt integrated fertilizers for sustainable wheat production and improving food security.
