When soil pH< 4.5, tea tree root growth was inhibited and the number of new roots was significantly reduced, which in turn contributed to a significant decrease in tea tree biomass, etc. (2021). Improvement of soil acidification in tea plantations by long-term use of organic fertilizers and its effect on tea yield and quality. It can be seen that effective adjustment of fertilizer application depth could promote the growth of tea trees. The meaning of DENITRIFICATION is the loss or removal of nitrogen or nitrogen compounds; specifically : reduction of nitrates or nitrites commonly by bacteria (as in soil) that usually results in the escape of nitrogen into the air. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. doi:10.15889/j.issn.1002-1302.2018.20.031, Dong, J., Zhang, J., Liu, Y., Jing, H. (2022). Better results could be achieved by reasonably controlling the application depth of sheep manure fertilizer. However, sometimes denitrification can be disadvantageous by removing the NO. Nitrification is a process in which the nitrogen-containing compound ammonia ( N H 3) is converted to nitrate ( N O 3 ). doi:10.3390/molecules24030415, Li, F., Li, H., Dong, C., Yang, T., Zhang, S., Bao, S., et al. The process mostly occurs at a temperature of 26C to 38C. In addition, there was a significant negative correlation between indexes concentrated on the negative end of principal component 1 and indexes concentrated on the positive end of principal component 1 (Figure9A). This study used the topsis model to analyze the effect of different indexes on fertilization effect, and the results showed (Figure11) that from 2018 to 2022, there were four main indexes that had strong effects on fertilization effect, namely root activity (10.22% to 12.58%), ammonium nitrogen (10.12% to 14.51%), ammoniation intensity (9.22% to 11.20%), and nifH gene (8.34% to 9.81%). (2020). Denitrifying bacteria like Spirillum, Lactobacillus, Pseudomonas, Thiobacillus. Influence of soil microbial activity and physical properties on soil respiration under maize (Zea mays l.). (2008). Secondly, the analysis revealed that the root activity and total root nitrogen content of tea trees remained at a high level when the application depth of sheep manure fertilizer was 50 cm and 70 cm (Figure3A). Li, H. R., Mei, X. R., Vinay, N. G., Guo, R., Liu, Y. E., Hao, W. P., et al. J. Effects of long-term use of organic fertilizer with different dosages on soil improvement, nitrogen transformation, tea yield and quality in acidified tea plantations. Effects of different nitrogen fertilizers on the yield, water- and nitrogen-use efficiencies of drip-fertigated wheat and maize in the north China plain. For example, soil urease promoted the transformation of soil organic nitrogen to ammonium nitrogen (Zhao etal., 2022), protease hydrolyzed organic nitrogen to amino acids (Greenfield etal., 2021), and nitrate reductase and nitrite reductase converted soil nitrogen to nitrate nitrogen (Koyama etal., 2020). 100, 14561463. Denitrification is a biological process of reduction of nitrate into nitrite, which is then followed by the reduction of nitrite into nitrogen gas that usually results in the removal of nitrogen gas into the air. China is the worlds largest tea growing country. Nitrification involves the conversion of reduced nitrogen compounds into oxidized forms. (Technically, it is a three step process: ammonification precedes nitrification and denitrification). Further analysis of the effect of soil pH on the expression of genes related to soil nitrogen transformation showed (Figure7C) that soil pH was significantly and positively correlated with the expression of soil nifH genes (R2 = 0.80, P< 0.01), while it was significantly and negatively correlated with the expression of soil amoA-AOA(R2 = 0.57, P< 0.01), narG(R2 = 0.64, P< 0.01), nirK(R2 = 0.52, P< 0.01), nirS(R2 = 0.51, P< 0.01)and nosZ(R2 = 0.66, P< 0.01)gene expression. Acta Physiol. J Water Health. (2022). Soil nitrogen transformation was performed by microbial populations containing specific functional genes. It can be seen that the key to improving the fertilization effect of sheep manure fertilizer was whether it could improve the root activity of tea trees, improve the transformation capacity and accumulation of ammonium nitrogen in soil, and then improve the absorption capacity of tea trees for ammonium nitrogen, and finally improve the yield and quality of tea leaves.

Secondly, it was found that soil urease and protease activities showed an overall increasing trend, while nitrate reductase and nitrite reductase showed a decreasing trend with longer application time of sheep manure fertilizer (from 2018 to 2022) (Figure6B). Valorization of pulp and paper industry wastewater using sludge enriched with nitrogen-fixing bacteria. The majority of Earth's atmosphere (78%) is atmospheric nitrogen, [16] making it the largest source of nitrogen. Biochem. The activity of the nitrifying bacteria also decreases in acidic conditions and at a temperature above 35C. A critical evaluation of two point-of-use water treatment technologies: can they provide water that meets WHO drinking water guidelines? Bioresource. Approximately, 40 and 60% of ammonium were converted to N2 gas and cell mass, respectively. Besides, denitrification follows nitrification in wastewater treatments to convert nitrogen-rich compounds into nitrogen gas before being released into the atmosphere. Effect of long-term pesticides and chemical fertilizers application on the microbial community specifically anammox and denitrifying bacteria in rice field soil of jhenaidah and kushtia district, Bangladesh. Changes in soil properties, bacterial communities and wheat roots responding to subsoiling in south loess plateau of China. It can be seen that the use of sheep manure fertilizer was conducive to alleviating soil acidification in tea plantations, raising soil pH, promoting root development and improving nitrogen uptake and utilization capacity of tea trees, thereby improving tea yield and quality, especially when the fertilization depth was 50-70cm. Microbes are responsible for . there are four missing hydrogen on the right hand side. Leaching and bioavailability of aluminium, copper and manganese from tea (Camellia sinensis). Behave. Denitrification is controlled by various factors like the concentration of oxygen and carbons, even though some aerobic bacteria of the genus Proteobacteria, might facilitate denitrification even in the presence of oxygen. Among them, only sheep manure fertilizer was used, and the specific application method was carried out according to the experimental design. doi:10.19675/j.cnki.1006-687x.2017.12008, Wang, Y., Cheng, X., Yang, T., Su, Y., Lin, S., Zhang, S., et al.

Sheep manure fertilization in Mimosa caesalpiniifolia in an albaquult. 41 (7), 14251432. 2012 Jan 17;46(2):722-8. doi: 10.1021/es203114q. In this study, it was found (Figure3A) that sheep manure fertilizer was beneficial to root activity and total root nitrogen content of tea trees, and the two indexes generally showed an increasing trend with the extension of sheep manure fertilization time (2018-2022). Each organic pesticide was used four times a year in March, July, August and September. In this study, it was found that with the increase in application depth of sheep manure fertilizer (0-100 cm), soil urease and protease activities showed a trend of increasing and then decreasing, while nitrate reductase and nitrite reductase showed the opposite trend, with the greatest effect on soil enzyme activities at application depths of 50 cm and 70 cm (Figure6A). However, it was necessary to control the application depth of sheep manure fertilizer during the fertilization process to achieve the best results. The main steps in the nitrogen cycle include nitrogen fixation, nitrification, denitrification, assimilation, ammonification, DNRA and anaerobic ammonia oxidation. The treatment with different application depths of sheep manure fertilizer was the worst when the application depth was 0 cm, followed by 30 cm and 100 cm, while the best results were obtained when the application depth was 50 cm and 70 cm. mainly *nitrous oxide (NO2)* and nitrogen gas (N2).) After continuous application of sheep manure fertilizer, the relationship between soil pH and tea yield and quality was further analyzed, and the results showed (Figure2B) that soil pH was significantly and positively correlated with tea yield (R2 = 0.82, P< 0.01), amino acid content (R2 = 0.69, P< 0.01) and theanine content (R2 = 0.65, P< 0.01) of tea leaves, and tea yield, amino acid and theanine content in tea leaves showed a significant upward trend with the increase in pH value. XJ and YW: Conceptualization, Visualization, Methodology, Writing original draft, Formal analysis, Writing review and editing, Funding acquisition. For example, soil pH was significantly negatively correlated with indexes concentrated on the negative end of principal component 1, while it was significantly positively correlated with indexes concentrated on the positive end of principal component 1 (Figure9B). The contact between plant roots and sheep manure fertilizer could accelerate the decomposition of soil organic matter, improve the efficiency of nutrients decomposition and release, and increase the pH value of soil (Yao etal., 2009). The TOPSIS entropy weight statistical analysis was performed on the SPSSAU online platform (https://spssau.com/). In this study, we found (Figure4C) that soil pH was significantly and positively correlated with soil ammonium nitrogen content (R2 = 0.65, P< 0.01), ammonifying bacteria number (R2 = 0.76, P< 0.01) and ammonification intensity (R2 = 0.55, P< 0.01) after continuous use of sheep manure fertilizer from 2018 to 2022, while it was significantly and positively correlated with soil nitrate nitrogen content (R2 = 0.76, P< 0.01), nitrifying bacteria number (R2 = 0.69, P< 0.01) and nitrification intensity (R2 = 0.49, P< 0.01) (Figure5C).

Some studies have shown that the use of rape cake and cow manure fertilizer can effectively alleviate soil acidification and thus improve crop yield and quality (Xie etal., 2021; Le etal., 2022; Yin etal., 2022). Denitrification seemed to predominate when BSFs were fed surface water. In this process, nitrogen in the combined state is reduced to its gaseous state. Relationships between nitrogen cycling microbial community abundance and composition reveal the indirect effect of soil pH on oak decline. eCollection 2020 Jun. The results found (Figure12) that the long-term use of sheep manure fertilizer was beneficial in alleviating soil acidification in tea plantations, improving soil pH and ammonium nitrogen content, enhancing root activity, which in turn led to an increase in the ability of tea tree roots to absorb nitrogen and an increase in tea yield and quality. 62 (7), 984997. doi:10.26651/allelo.j/2022-56-2-1397, Ding, L., Zhang, Q.

Further analysis revealed that with the increase of the depth of application of sheep manure fertilizer (0 - 100 cm), soil nitrate nitrogen content, nitrifying bacteria population and nitrification intensity showed a decreasing and then increasing trend, with the minimum at 50 cm and 70 cm (Figure5A). 55, 229242. Nitrogen is a component of many cells and processes in living organisms. 2023. Thanks for the correction. Nitrification is an essential step in the nitrogen cycle of natural systems because it links organic matter degradation to fixed nitrogen loss. Appl. Nitrifying bacteria also play an important role in wastewater treatment where different nitrogen compounds are converted into nitrates and then nitrogen before removing the gas out of the water. The nitrates then fall from the atmosphere onto the soil, which plants can use as well. These organisms convert ammonia into nitrates which is more soluble than ammonia and thus can be taken into the system more conveniently. The application depth of sheep manure fertilizer was 0 cm, 15-30 cm (30 cm), 15-50 cm (50 cm), 15-70 cm (70 cm), and 15-100 cm (100 cm) in A1, A2, A3, A4, and A5 tea plantations, respectively.
