Microbiological Indicators for Assessing the Effects of Agricultural Practices on Soil Health: A Review

Agronomy, Journal Year: 2025, Volume and Issue: 15(2), P. 335 - 335

Published: Jan. 28, 2025

Agricultural practices significantly impact soil properties and ecological functions, highlighting the importance of comprehensive health assessments. Traditionally, these assessments have focused on physical chemical indicators, often neglecting microbiological properties. This review explores potential indicators in evaluating effects agricultural emphasizing their significance addressing challenges associated with application. A key advantage is high sensitivity rapid response to environmental changes. These can be grouped into three categories: microbial biomass abundance, taxonomic composition diversity, activity. Among these, carbon, basal respiration, decomposition rates are considered most reliable interpretable indicators. Microbial diversity remain limited diagnostic predictive capabilities due interpretation. Integrating offers a more holistic understanding interactions between health, enhancing our ability monitor, manage, preserve ecosystems. To facilitate adoption production land management, further efforts needed improve interpretability establish standardized criteria for assessment.

Abstract In order to address the global crisis in pear productivity, there has been increased attention given advocating for use of organic fertilizers. As part this effort, researchers have investigating microbial properties fertilizers better understand their potential impact on fruit productivity. Our research focused specifically four different ratios sheep manure (SM) and chemical (CF) We found that replacing CF with SM resulted a proliferation gammaproteobacteria, Chlamydiae, Bastocatellia Clostridia soil rhizosphere, which is region around roots plants where most nutrient uptake occurs. Using redundancy analysis, we were able determine was particularly effective at promoting growth gammaproteobacteria clostridia, associated C:N 14:1 as well availability K, Fe, Zn Cu. This combination factors conducive transition from vegetative reproductive growth, resulting an increase production 43 56 tons per hectare. also discovered Blastociella acts buffering system regulating acidity. Taken together, our findings indicate can improve abundance beneficial bacteria leading

Effects of humic acid fertilizer on the growth and microbial network stability of Panax notoginseng from the forest understorey

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 1, 2024

Humic acid (HA) can substantially enhance plant growth and improve soil health. Currently, the impacts of HA concentrations variation on development quality Panax notoginseng (Sanqi) from forest understorey are still unclear. In this study, exogenous was administered to roots Sanqi at varying (2, 4, 6 ml/L). Subsequently, diversity community structure bacteria fungi were assessed through high-throughput sequencing technology. The investigation further involved analyzing interplay among sanqi, edaphic factors, microbial network stability. Our finding revealed that moderate (4 ml/L) improved fresh/dry weight NO3-−N levels. Compared with control, had a notable impact bacterial fungal communities compositions. However, there no significant difference in α β fungi. Moreover, abundance beneficial (Bradyrhizobium) harmful (Xanthobacteraceae) increased decreased 4 ml/L HA, respectively, while stability enhanced. Structural equation model (SEM) fresh factors directly affected HA. conclusion, is for promoting quality. study provides reference increasing yield sustainable Sanqi-pine agroforestry system.

Comparing struvite, K-struvite and hydroxyapatite for the remediation of lead and cadmium contaminated soil

Sustainable Horizons, Journal Year: 2024, Volume and Issue: 10, P. 100084 - 100084

Published: Jan. 10, 2024

Heavy metal pollution leads to severe soil contamination and raises environmental concerns. Phosphorus-bearing minerals have been identified as effective environmentally friendly agents for remediating contaminated soil. However, using recycled phosphorus remediation remains limited. In this study, we investigated the potential use of recovered magnesium ammonium phosphate (MAP), potassium hydrate (KMP), hydroxyapatite (HAP) immobilize lead (Pb) cadmium (Cd) in The effectiveness MAP, KMP, HAP modifying chemical composition Pb Cd reducing their mobility was demonstrated by results. When added at dosages 5:1 10:1, extractable fraction decreased 0.43–13.43 % control group. Similarly, 49.18–76.44 group same dosages. Moreover, application these products resulted an increase pH value, urease activity, bacterial Shannon index, thereby enhancing properties. immobilization effects were more significant Pb-contaminated compared Cd-contaminated soil, MAP KMP exhibited a stronger passivation effect on comparison HAP. For fertility improvement, molar ratio 10:1 recommended, whereas effectively passivated These findings provide evidence feasibility utilizing heavy metals polluted
