Increasing organic fertilizer application can improve the sustainability of soil productivity, but the effects of increased organic fertilizer application with reduced chemical fertilizer application over different time periods on chemical properties and bacterial community of grape rhizosphere soil in an arid region are not clear. In this study, three years of fixed-point field tests were used to compare the effects of various fertilization treatments on the soil properties and bacterial community in the grape rhizosphere. The results showed that (1) T1 and T2 significantly increased SOM, AN, AP and AK contents in grape rhizosphere soil. TN, TP and TK contents in grape leaves of T2 were the highest of those in five fertilization treatments. (2) The abundances of Proteobacteria and Bacteroidetes phyla and especially of Arthrobacter, Pseudomonas, Nitrosopira and Bacillus genera were higher in T2 than in the other samples. (3) SOM, AP and AN contents in soil were the main factors affecting soil bacterial community and mineral element contents in grape leaves and roots according to an RDA analysis. In summary, the application of organic fertilizer with reduced chemical fertilizer for two years had the greatest impact on the soil properties and bacterial community of the grape rhizosphere soil. Soil microbes play an important role in maintaining soil productivity through biochemical processes such as litter decomposition and nutrient recycling 1. The soil microbial community is an important factor influencing plant health because plant disease resistance mainly relies on the rhizosphere microbial community 2. Microbes are regarded as early warning indicators of soil quality because of their rapid response and sensitivity to environmental changes 3. Soil properties are greatly influenced by agronomic practices such as tillage, irrigation, and fertilization 4. Fertilization is widely used worldwide to improve soil fertility. Excessive fertilizer application aggravates the decline of soil organic matter and fertility and accelerates soil acidification 5. Soil properties affect the community structure of soil microbes 6. Fertilization influences soil microbial diversity through direct effects on the soil nutrient content 7. Soil microbial communities are sensitive to fertilization and their responses to manure and/or mineral fertilizers in soils have been well studied over the past several years 8,9. The long-term application of nitrogen fertilizer or nitrogen fertilizer in combination with other mineral fertilizers affects the nitrogen cycle and related bacterial populations 10. Repeated overuse of chemical fertilizer can have a negative effect on soil quality and soil microbial community structure. The long-term application of chemical fertilizers can significantly reduce soil pH which is closely associated with decreased bacterial diversity and significant changes in bacterial community composition, livestock manures can prevent soil acidification and its effects on soil bacteria 11. Geisseler and Scow found that with...

“…The organic fertilization (fallow or manure) in combination with chemical fertilizers was also demonstrated to support the increase of copiotrophic taxa and labile C-degrading genes [57], both components responsible for enhanced nutrient cycling in soil that, in turn, improves soil productivity. The combination of organic fertilizer (e.g., organic manure) with a balanced chemical fertilization positively affecting the abundance and diversity of microbial populations (bacteria and fungi) [61].…”

Short-Term Effects of Sewage Sludge Compost Amendment on Semiarid Soil

The adoption of sewage sludge as an agricultural management strategy to improve soil properties and crop production is attracting great interest. Despite many positive effects on soil inorganic and organic components reported for different soil types, little information is available on sewage sludge application on Mediterranean soils, as well as on its use at different dose rates. The objectives of the present research was to evaluate, through an integrated approach, the effects of sewage sludge compost from urban wastewater on physicochemical, hydrological, biochemical parameters, and microbiota composition in soil pots under a three-year crop rotation system. Four different doses of sewage sludge compost (C3, C6, C9, C12) from municipal wastewater and a dose of them in combination with mineral fertilizer (C6N) were used. We have used 3-6-9-12 Mg/ha of sewage sludge compost for the treatments C3, C6, C9 and C12, respectively, and 6 Mg/ha of sewage sludge compost in combination with 60 kg/ha of ammonium nitrate for the treatment C6N.The effects were compared to non-fertilized (C0) and mineral fertilized (Min) sets of controls. The electrical conductivity, soil pH, stability of soil aggregates, percent of moisture of the dry soil both at the field capacity and at the wilting point, available P, and exchangeable K were all positively affected by increasing the amounts of composted sludge. The organic carbon and total N increased up to 66% and 39%, respectively. Increased enzymatic activities and microbial biomass were also observed in soil after the application of sewage sludge compost when compared to un-amended control. A higher richness and evenness among the soil plots amended with sewage sludge compost was observed, with no significant differences among the application dose rates, when compared to the un-amended soil control and soil treated with a mineral fertilizer. A three-year amendment was able to separate soil plots amended with high doses of sewage sludge compost from the low dose amended and control samples. Among the microbial groups responsible for such marked separation, bacteria belonging to Actinobacteria, Acidobacteria, Cyanobacteria and Bacteroidetes contribute the most, with a shift from oligotrophic to copiotrophic taxa. Significant changes in bacterial composition and taxonomic structure should be considered in order to properly balance agronomic and economic advantages with environmental concerns. After all, our results have evidenced the effects of sewage sludge amendment on different soil properties, microbial activity, and composition already after a short period of application. The findings are particularly relevant in semiarid soils, where an immediate restoration of soil fertility by short-term compost application is needed.

“…According to the National Bureau of Statistics of China, in Heilongjiang Province in Northeast China, where the total grain output was 75.05 billion kg in 2018, accounting for more than 10% of China's total grain output, erosion of its iconic black soil occurrs because of excessive application of chemical fertilizer ( http://www.xinhuanet.com ). The use of such large amounts of N, organic fertilizer, and organic fertilizer combined with chemical fertilizer has posed severe challenges to the soil microbial community, including bacteria 3 , fungi 4 , 5 , acidobacteria 6 , arbuscular mycorrhizal fungi 7 , 8 , diazotrophs 9 , and ammonia oxidizing archaea 10 , in black soil in northeast China.…”

Fertilizer-induced changes in soil nutrients regulate nitrogen (N) fixation in the terrestrial biosphere, but the influences of N and phosphorus (P) fertilization on the diazotroph communities in successive crop seasons were unclear. In this study, we assessed the effects of N and P (high vs. low doses) on the abundance and structure of N2-fixation communities after wheat and soybean harvest in a long-term (34 and 35 years) fertilization experiment. In both seasons, long-term N addition significantly decreased the abundance of nifH genes and 16S rDNA; in addition, high doses of N and P fertilizer decreased the richness of diazotrophs, whereas low doses did not. The proportion of the dominant genus, Bradyrhizobium, in the soybean season (86.0%) was higher than that in the wheat season (47.9%). Fertilization decreased diazotroph diversity and the relative abundance of Bradyrhizobium in the wheat season, but had insignificant effects in the soybean season. The addition of N, but not P, significantly changed the communities of both diazotrophs (at the genus level) and rhizobia (at the species level) in the two seasons. Soil pH was positively associated with nifH abundance and diazotrophic richness; soil NO3− content was negatively correlated with diazotrophic richness and positively correlated with diversity. Soil pH and NO3− content were the two main drivers shaping the soil diazotrophic community. Overall, long-term inorganic N had a greater influence than P on both diazotrophic abundance and community composition, and diazotrophic diversity was more clearly affected by fertilization in the wheat season than in the soybean season.
