“…The possible reason for the higher soil quality might be the higher porosity and higher surface area of biochar and a large number of microspores (Jaafar, Clode & Abbott, 2015a;Jaafar, Clode & Abbott, 2015b). Ali et al (2020), Zhang et al (2019), Kuzyakov, Bogomolova & Glaser (2014), and Liang et al (2014) reported similar effects of biochar on the improvement of soil physiochemical properties. In addition, biochar amendments increase the adsorption of Different litters above the curve indicate statistical significance at the (P < 0.05).…”

“…Similarly, enriched soil enzymatic activities (Oladele, 2019) increased the leaf N metabolism activity (Farhangi-Abriz & Torabian, 2018) and soil microbial biomass, which improved the chlorophyll fluorescence traits. The combined application of biochar and N to soil also improves plant photosynthetic traits (Ali et al, 2020), which may result in increased fluorescence. Our results are in agreement with those of Chen et al (2016), who reported that moderate levels of biochar improved the chlorophyll fluorescence attributes.…”

“…For example, many studies of various taxa and in different environments have confirmed strong, positive correlations between the leaf N content and the photosynthesis rate (Field & Mooney, 1986;Reich et al, 1998). Biochar applications might increases the net photosynthetic rate of rice, stomatal conductance, transpiration rate, and water use efficiency (Ali et al, 2020). In addition, biochar addition to soil influences soil N dynamics, thus affecting the available N (AN) in the soil (Clough & Condron, 2010;Clough et al, 2013), N adaptation, and biological N fixation in plants Notes.…”

The excessive use of synthetic nitrogen (N) fertilizers in rice (Oryza sativa L.) has resulted in high N loss, soil degradation, and environmental pollution in a changing climate. Soil biochar amendment is proposed as a climate change mitigation tool that supports carbon sequestration and reduces N losses and greenhouse gas (GHG) emissions from the soil. The current study evaluated the impact of four different rates of biochar (B) (C/B0-0 t ha−1, B1-20 t ha−1, B2-40 t ha−1, and B3-60 t ha−1) and two N levels (N1; low (270 kg N ha−1) and N2; high (360 kg N ha−1)), on rice (cultivar Zhenguiai) grown in pots. Significant increases in the average soil microbial biomass N (SMBN) (88%) and carbon (87%) were recorded at the highest rate of 60-ton ha−1B and 360 kg N ha−1 compared to the control (N1C) during both seasons (S1 and S2). The photochemical efficiency (Fv/Fm), quantum yield of the photosystem (PS) II (ΦPS II), electron transport rate (ETR), and photochemical quenching (qP) were enhanced at low rates of biochar applications (20 to 40 t B ha−1) for high and low N rates across the seasons. Nitrate reductase (NR), glutamine synthetase (GS), and glutamine 2-oxoglutarate aminotransferase (GOGAT) activity were, on average, 39%, 55%, and 63% higher in the N1B3, N2B2, and N2B3 treatments, respectively than the N1C. The grain quality was higher in the N1B3 treatment than the N1C, i.e., the protein content (PC), amylose content (AC), percent brown rice (BRP), and percent milled rice (MRP) were, on average, 16%, 28%, 4.6%, and 5% higher, respectively in both seasons. The results of this study indicated that biochar addition to the soil in combination with N fertilizers increased the dry matter (DM) content, N uptake, and grain yield of rice by 24%, 27%, and 64%, respectively, compared to the N1C.

“…Luo et al [21] reported that organic manure applications with a high N content and low C: N ratio could mineralize enough N to satisfy the demands for plant growth. However, organic fertilizer is quite low in nutrients and its nutrient releasing ability is also slow to meet plant requirements in a short period of time, therefore manure coupled with synthetic fertilizer has been confirmed to be a better approach to improve and sustain soil fertility and crop production than sole application of manure or synthetic fertilizer [22][23][24].…”

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.

Synthetic fertilizer with organic fertilizer (OF) is an approach for the improvement of soil health and quality without compromising crop yield. Therefore, a two-year eld experiment was conducted to explore optimal chemical fertilizer (CF) management strategies in the context of OF, such as cattle manure (CM) and poultry manure (PM) fertilization to Ultisol soil to improve soil microbial biomass production, enzyme activities and nutrient contents, as well as grain yield of rice.
