The large yield of anaerobic digestates and the suboptimal efficacy nutrient slow-release severely limit its practical application. To address these issues, a new biochar based fertilizer (MAP@BRC) was developed using biogas residue (BRC) to recover nitrogen phosphorus from slurry. release patterns MAP@BRC mechanisms for enhancing soil fertility were studied, it demonstrated excellent performance, with 59% total 50% rates within 28 days. This attributed coupling mechanism involving dissolution struvite skeletons pores. Pot experiments showed that crop water productivity doubled in group compared unfertilized planting. application also improved levels, reduced acidification, increased microbial populations, decreased heavy metal pollution risk. key factors contributed improvement by an increase available optimization pH levels soil. Overall, is safe, exhibits biochar-fertilizer interactions synergistic effects. prepared treating phosphorus-rich slurry nitrogen-rich slurry, simultaneously addresses problems associated livestock waste treatment provides promising strategy promote zero-waste agriculture.

Introduction Global mining activities have significant impacts on ecosystems, but most studies focused only the relationship between soil physicochemical properties and microbial diversity in soils. The present study provides an insight into effects of physico-chemical endophytic bacterial community composition rhizosphere three different crops. Methods Musa basjoo Siebold L., Amygdalus persica Triticum aestivum L. were collected from inter-root soils plant roots to determine communities root system. Results results showed that resulted acidification, altered trace element content increased organic carbon. There was increase Ascomycota Actinobacteria phylum crop bacteria. Interestingly, chao1 shannon indices endophytes significantly elevated compared contro ( p < 0.05). Among them, highest level richness environment. environment functional enrichment histidine kinases oxidoreductases community. total potassium (TK) soil, as well Fe Pb content, positively correlated with α-diversity index Streptomyces . Zn Ti negatively index. Discussion This data support for exploring mechanisms response developing ecological restoration strategies areas.

Subsidence from coal mining is a major environmental issue, causing significant damage to soil structure. Soil microorganisms, highly sensitive changes, adapt accordingly. This study focused on four areas of the Burdai mine: non-subsidence area (CK), half-yearly (HY), 1-year (OY), and 2-year (TY) subsidence areas. Using high-throughput sequencing molecular ecological network analysis, we examined microbial community diversity structure across these zones, exploring assembly functional predictions. Results showed that compared control, experienced reduced water content, organic matter, available phosphorus, alkaline nitrogen, with lowest levels observed at 1 year. These values began rise after year, suggesting natural recovery stabilized. Microbial communities were closely related nitrogen. At mark, property changes significantly diversity, which then recover 2 years. The during was simpler, 102 nodes, 179 edges, an average degree 3.51, indicating early unstable, still adapting. By interactions had begun stabilize. Stochastic processes played key role in variability short-term subsidence.

Heavy metal contamination in soil is a serious environmental challenge, and abandoned mining areas are of particular concern. In order to rehabilitate the ecology these areas. this study, we used ICP-MS potentiometric method analyze physicochemical then endophytic bacteria remediation plants with help 16sRNA sequencing, investigate ecological ilmenite mine effect microbiology by seven common plants. The results revealed that abandonment significantly increased contents total phosphorus, potassium, available iron, lead surrounding soils. It also affected richness diversity bacterial communities. Pvi had highest richness, while Tsi lowest ( P < 0.05). A 28 phyla, 69 classes, 171 orders, 521 genera were identified. nine core OTUs found: Stenotrophomonas , Chryseobacterium Lactobacillus Clostridium_sensu_stricto_12 Prevotella Bradyrhizobium Nocardioides Delftia . Beta analysis community structure differed during process at site. Functional prediction upregulation Dco transporter protein function, DNA-binding transcriptional regulators, glyoxalase or related metal-dependent hydrolases, acyl coenzyme synthetases, ATPase components, amino acid synthesis, cellular respiration-related functions.

Abstract Changes in soil characteristics due to varying farming practices can modify the structure of bacterial communities. However, it remains uncertain whether groups that break down organic material are similarly impacted. We examined changes community by pyrosequencing 16S rRNA gene when young maize plants, their neutral detergent fibre fraction, or urea were applied an Australian Vertisol. This was managed with either conventional tillage continuous cotton, minimum a wheat‐cotton rotation. The carbon content 1.4 times higher rotation than cotton treatment. Approximately 41.6% added and 13.1% fraction mineralized after 28 days. application plants significantly altered presumed metabolic functional structure, but did not. Many groups, such as Streptomyces , Nocardioides Kribbella functions enriched material, less so urea. found limited number affected irrigated Vertisol different systems, many strongly its fibre.
