“…Moreover, such effects were weakened with increasing soil depth, which was consistent with previous research results (Sainju et al 2003). Silt-clay particles can be considered as a stable stock and are slightly affected by agronomic practices compared with soil macro-aggregates (Zou et al 2018).…”

“…Field-moist soil was MWD mean weight diameter, GMD geometric mean diameter used to avoid possible disruption during rewetting of soil dried in air (Kemper and Rosenau 1986). The samples were wet sieved through a series of three sieves to acquire four aggregate size fractions: large macro-aggregates (> 2000 μm), small macroaggregates (250 to 2000 μm), micro-aggregates (53 to 250 μm), and silt and clay (< 53 μm) and corrected for dry mass as described in Zou et al (2018).…”

“…This treatment had the lowest BD, MWD, and GMD. The reason was that long-term application of nitrogen fertilizer can worsen soil structure and reduce the proportion of macro-aggregates, so that soil structure becomes simplified and stability of aggregates is damaged (Zou et al 2018).…”

Long-term mono-cropping and excessive chemical fertilizer application reduce water-stable soil aggregate stability and soil N and C stocks in tobacco production. This study tested the hypothesis that rotation and fertilizer type affected the proportion of water-stable aggregates and aggregate-associated soil organic carbon (SOC) and total soil nitrogen (TSN) concentrations. Two planting systems (tobacco mono-cropping and tobacco-maize rotation) with five fertilizer treatments (0 and 75 kg N ha −1 , 450 kg oil cake + 75 kg N ha −1 , 15,000 kg farmyard manure + 60 kg N ha −1 , and 3000 kg straw + 75 kg N ha −1) were established in 2007. After 10 years, rotation and fertilizer type significantly affected soil aggregates and associated SOC and TSN at different soil depths. Rotation significantly increased mean weight diameter (MWD) and geometric mean diameter (GMD); GMD increased with increasing soil depth. Rotation and organic fertilizer effectively increased the proportion of large macro-aggregates and MWD and GMD, while significantly reducing the proportion of micro-aggregates. The effect of fertilization type and rotation on the SOC content of large macro-aggregates was more obvious than that on TSN content, but there was no significant effect on SOC and TSN contents of aggregates < 250 μm. Rotation and organic fertilizer significantly increased SOC stock and total nitrogen of soil macro-aggregates (> 250 μm). However, this trend weakened with increasing soil depth and decreasing aggregate size. Rotation and organic fertilizers used in tobacco production stabilized the proportion of macro-aggregates in surface soil and maintained SOC and TSN better. Keywords Flue-cured tobacco. Rotation.

“…Many studies were conducted on a weight basis rather than the application of manure of a specific N concentration combined with synthetic N fertilizer [31][32][33]. This has created a research gap in finding out the effects of integrated nutrient management based on specific composition rather than weight.…”

Excessive reliance on chemical fertilizer (CF) in conventional farming is a serious concern owing to its negative effects on soil health, the environment, and crop productivity. Organic manure is an alternative source of fertilizer to reduce the amount of CF usage in agriculture, decrease environmental pollution, and ensure sustainable crop production. This study assessed the integrated effect of poultry manure (PM) and cattle manure (CM) with CF on soil properties, plant physiology, and rice grain yield. Additionally, the difference in pre-and post-anthesis dry matter (DM) and nitrogen (N) accumulation and their relationship with grain yield was also determined. Pot experiments were performed in the early and late growing season at the experimental station of Guangxi University, China, in 2018. A total of six treatments, i.e., T 1-CF 0 ; T 2 −100% CF; T 3 −60% CM + 40% CF; T 4 −30% CM + 70% CF; T 5 −60% PM + 40% CF, and T 6 −30% PM + 70% CF were used in this pot experiment. Results showed that T 6 enhanced leaf photosynthetic efficiency by 11% and 16%, chlorophyll content by 8% and 11%, panicle number by 12% and 16%, and grain yield by 11% and 15% in the early and late seasons, respectively, compared to T 2. Similarly1, post-anthesis N and DM accumulation, N uptake, and soil properties (i.e., soil organic carbon, total N, and bulk density) were improved with integrated CF and manure treatments over the sole CF treatments. Interestingly, increases in post-anthesis N uptake and DM production were further supported by enhanced N-metabolizing enzyme activities (i.e., nitrate reductase, glutamine synthetase, and glutamate oxoglutarate aminotransferase during the grain-filling period in combined treatments. In-addition, the linear regression analysis showed that postanthesis DM (R 2 = 0.95) and N (R 2 = 0.96) accumulation were highly associated with grain yield of rice. Thus, the combination of 30% N from PM or CM with 70% N from CF (i.e., urea) is a promising option for improvement of soil quality and rice grain yield. Furthermore, our study provides a sustainable nutrient management plan to increase rice yield with high N use efficiency.

“…SOM plays an important regulatory role in the complex buffering processes in soils. Organic fertilizer application not only improves the soil physical characteristics 20 , but also promotes microbial activity and speeds up the degradation of SOM in soils 21 . To understand exactly the effect of organic fertilizer on soil fertility and NUE, location fertilization has been used to explain these changes 8 .…”

It is great of importance to better understand the effects of the long-term fertilization on crop yields, soil properties and nitrogen (N) use efficiency in a rotation cropping cultivation system under the conditions of frequent soil disturbance. Therefore, a long-term field experiment of 40 years under soybean-maize rotation was performed in a brown soil to investigate the effects of inorganic and organic fertilizers on crop yields, soil properties and nitrogen use efficiency. Equal amounts of 15N-labelled urea with 20.8% of atom were used and uniformly applied into the micro-plots of the treatments with N, NPK, M1NPK, M2NPK before soybean sowing, respectively. Analyses showed that a total of 18.3–32.5% of applied N fertilizer was taken up by crops in the first soybean growing season, and that the application of manure combining with chemical fertilizer M2NPK demonstrated the highest rate of 15N recovery and increased soil organic matter (SOM) and Olsen phosphorus (Olsen P), thereby sustaining a higher crop yield and alleviating soil acidification. Data also showed that no significant difference was observed in the 15N recovery from residue N in the second maize season plant despite of showing a lower 15N recovery compared with the first soybean season. The recovery rates of 15N in soils were ranged from 38.2 to 49.7% by the end of the second cropping season, and the residuals of 15N distribution in soil layers revealed significant differences. The M2NPK treatment demonstrated the highest residual amounts of 15N, and a total of 50% residual 15N were distributed in a soil layer of 0–20 cm. Our results showed that long-term application of organic fertilizers could effectively promote N use efficiency by increasing SOM and improving soil fertility, and thus leading to an increase in crop yields. This study will provide a scientific reference and guidance for improving soil sustainable productivity by manure application.
