“…Therefore, the current research is helpful to distinguish the outcomes of goat manure (M), sugarcane straw (S), or goat manure + sugarcane straw (MS) on SF, with a focus on the soil bacterial communities' structures with different periods. Organic fertilizer application in soil increases or stabilizes the soil pH [4,33,34]. 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].…”

“…Soil degradation and acidification are the leading problems triggered by the application of fertilizers, especially nitrogen fertilizers (N), in order to produce high yields which, in turn, lead to a drastic reduction in soil fertility, including crop yields [2][3][4]. On the contrary, agricultural farming depends on the utilization of organic fertilizers, which is not only highly promising in reducing the application of mineral fertilizers, but also enhances the crop productivity via ensuring ecosystem sustainability [4][5][6][7][8]. In order to increase the SF and productivity, animal manure and crop residues as soil amendments are considered a great agricultural practice [9,10].…”

“…They have great metabolic functions and are indispensable for almost all biogeochemical processes [4,17]. Using organic fertilizers on agricultural land has a promising effect on bacterial communities in the soil [4]. Fluctuations in bacterial populations in the soil in relation to diverse agricultural practices can help us explain the processes of nutrient cycling in the soil.…”

“…However, current studies have employed HTS to understand the soil microbial diversity and composition under various organic amendments [9,10,23]. Much work on the potential utilization of organic fertilizers as a promising approach in order to recover soil fertility in agriculture has been carried out [4,24,25]. However, the impact of organic amendments in clay-loam soils in terms of a specific period of time was yet to be explored.…”

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.
