“…However, the findings of this study indicated that M1, MS1, M2, and MS2 amendments were more effective in increasing the soil pH, which is consistent with the previous results of Han et al [35] and Das et al [9]. Adding various organic supplements to the soil enhances the accumulation of basic macronutrients, especially N, K, and P, as well as soil organic matter [16]. Correspondingly, our results suggested an improvement of various soil properties in M1, MS1, M2, and MS2 amendments, such as TC, AP, AK, TN, AN, NH 4 + , NO 3 − , compared to CK1, CK2, and S1, S2 with the same amendment rate in both phases (Table 1).…”

“…Furthermore, we believe that the high nutrient availability reduced the species richness in M1-, M2-, MS1-, and MS2-amended soil and a small quantity of nutrients stimulated their growth in CK1, CK2, as well as in S1, S2, in both phases. [9,16]. It is assumed that the increase in beneficial bacterial composition and biomass, including greater availability of C, P, and N in the M1-, M2-, MS1-, and MS2-amended soils, will improve the fertility of the soil.…”

“…Overall, three replications were considered for each pot. According to Sun et al's [16] experiment, mean low and high air temperature (18-30 • C) and 75-80% of relative humidity were maintained throughout the trial. Pots of every treatment were irrigated by one liter of distilled water on a weekly basis.…”

“…In the same way, decomposed leaves take part in the release of essential nutrients and these nutrients are important for the growth and development of plants [12,13,15]. More recent evidence has suggested that the addition of litter has a significant effect on the development of soil microbiota leading towards higher nutrient levels in soil and microbial biomass [16].…”

Effect of Sugarcane Straw and Goat Manure on Soil Nutrient Transformation and Bacterial Communities

et al. 2018

Crop residue and animal manure as a soil amendment have been recognized as a feasible agricultural practice owing to its contribution in improving the soil fertility (SF). The primary advantages of this practice are determined by the activities of soil microorganisms. However, goat manure (M), sugarcane straw (S), and goat manure plus straw (MS) amendments influence soil bacteria, their activities, and SF in clay-loam soil remains undefinable. Therefore, this study distinguished the efficacy of M, MS, and S amendment on soil enzyme activities and the availability of nutrients, including various bacterial populations in clay-loamy soil with respect to two different phases (50 and 100 days). In order to analyze the bacterial structure and their activities, we employed high-throughput sequencing (HTS) and soil enzyme activity (SEA) tests. Soil amended with M and MS not only significantly enhanced nutrient availability, including C, P, and N, soil pH, as well as SEA for C and N cycles in both phases. Additionally, the increase in nutrient availability was greater in M-and MS-amended soils in the second phase (100 days) compared to the M-and S-amended soils in the first phase (50 days). Moreover, plant growth promoting and lignocellulose degrading bacterial genera were enhanced under M-and MS-amended soil compared to S-amended soil in both phases. Distance-based redundancy analysis (dbRDA) showed that soil pH, carbon-nitrogen ratio (C:N), and nitrates (NO 3 − )were inducing the fewest changes, while total nitrogen (TN), total carbon (TC), available nitrogen (AN), available phosphorus (AP), total phosphorus (TP), available potassium (AK), and ammonium (NH 4 + )were the main operators in terms of change in bacterial populations. In general, we observed that M and MS are better amendment sources as compared to S amendment in order to enhance the SF in the clay-loamy soil in both phases, but greater fertility was exhibited in the second phase.

“…Another possibility is that the harvesting residues and litters of the previous generation were retained in the 10yr stand, affecting soil fertility. Studies have shown that remainder and litter can increase the soil humus and improve soil fertility (Sun et al, ). However, the soil properties of the 15yr and 18yr E .…”

Effects of the successive planting of Eucalyptus urophylla on soil bacterial and fungal community structure, diversity, microbial biomass, and enzyme activity

et al. 2019

Eucalyptus are a widely used short‐rotation species for timber production in South China. There are growing concerns regarding the influences of successive planting of Eucalyptus urophylla on microorganisms and soil. The aim of this work was to determine the effects of the successive planting of E. urophylla on soil characteristics. Five different stands, including 5‐, 10‐, 15‐, and 18‐year‐old E. urophylla plantations (abbreviated as 5yr, 10yr, 15yr, and 18yr, respectively) and one native evergreen broadleaf forest as a 0‐year‐old E. urophylla plantation (abbreviated as CK) were used. All of measured chemical indicators, microbial biomass, and enzyme activities were significantly lower in E. urophylla plantations compared with CK stand. The microbial biomass and enzyme activities significantly decreased in 5yr stand, significantly increased in 10yr stand, and subsequently declined in 15yr and 18yr stands. The relative abundance of Ascomycota in 15yr (77.10%) and 18yr (72.71%) plantations was significantly higher than in other stands. Basidiomycota relative abundance in the E. urophylla plantations was significantly lower than in the CK stand. In addition, the bacterial diversity was significantly decreased in 15yr and 18yr stands, whereas the fungal diversity was the lowest in 5yr stand and significantly increased in 10yr, 15yr, and 18yr stands. Furthermore, structural equation modelling showed that successive planting of E. urophylla decreased the soil bacterial community diversity, microbial biomass, and enzyme activity but increased the fungal community diversity. Thus, successive planting of E. urophylla negatively influenced the soil bacterial diversity, microbial biomass, and enzyme activity and positively influenced soil fungal diversity.
