Enhancing soil health through balanced fertilization: a pathway to sustainable agriculture and food security

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 16

Published: April 28, 2025

Sustainable soil health management is pivotal for advancing agricultural productivity and ensuring global food security. This review comprehensively evaluates the effects of mineral-organic fertilizer ratios on microbial communities, enzymatic dynamics, functional gene abundance, holistic health. By integrating bioinformatics, enzyme activity assays, metagenomic analyses, we demonstrate that balanced fertilization significantly enhances diversity, community stability, resilience against environmental stressors. Specifically, synergistic application mineral organic fertilizers elevates β -glucosidase urease activities, accelerating matter decomposition nutrient cycling while modulating taxa critical transformation pathogen suppression. Notably, replacing 20–40% with alternatives mitigates risks such as greenhouse gas emissions leaching sustaining crop yields. dual approach improves structure, boosts water retention capacity, increases biomass by 20–30%, fostering long-term fertility. Field trials reveal yield 25–40% in crops like rice maize under combined fertilization, alongside enhanced carbon (110.6%) nitrogen content (59.2%). The findings underscore necessity adopting region-specific, strategies to optimize ecological sustainability productivity. Future research should prioritize refining frameworks through interdisciplinary approaches, addressing soil-crop-climate interactions, scaling these practices diverse agroecosystems. aligning policies principles, stakeholders can safeguard health—a cornerstone human wellbeing—while securing resilient systems future generations.

Concentrations, source identification and environmental risk assessment of potentially hazardous elements in agricultural soils of Hamedan, west of Iran

International Journal of Environmental & Analytical Chemistry, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 15

Published: March 21, 2024

In the current study, a total of 40 agricultural surface soil samples were collected from sites in Hamedan, Iran and contents As, Cd, Cr, Cu, Ni, Pb, Zn determined by ICP-OES. The average all analysed elements except Pb found to be greater than those background reported for Iran, which could presumably show anthropogenic sources these elements. EF PI values decreased order As > Cr Cu Cd Ni while, rank mean I-geo followed Pb. Additionally, cumulative RI with 175, demonstrated 'moderate ecological risk' across investigated area. results PCC, PCA, HCA showed that traffic activities regarded as most important factors affected content PTEs soils. conclusion, an accurate investigation on probability environmental risks due pollution other persistent organic pollutants (POPs) is recommended future works.

Prediction of the impact of ecological restoration technology on the restoration of heavy metal pollution in agricultural soil

Geology Ecology and Landscapes, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 17

Published: March 17, 2024

Heavy metal in agricultural soils increases its contamination and infertility a due course of time. The vast expansion industrialization along the has led to such adverse effects impacting vegetation. Several existing learning techniques are utilized analyze soil; however, process consumes high restoration error rate. This article introduces Concentration-specific Restoration Prediction Technique (CRPT) for heavy metal-exposed soils. technique relies on level present different soil types assessing impact. vegetation failures progressions accounted by continuous recurrent predicting age. procedures preferred earlier stages used training neural network. Based more feasible method, failure validated achieving maximum prediction value. accounts type, crop resistance, climatic factors holding procedures. Therefore, performs with resistance analysis progressive prediction. least possible value is using inputs matching outputs. reliable detecting pollution possibility (9.41%) less (14.53%).

With the development of sustainable agriculture, trials on benefits application organic fertilizers around world have been conducted. Herein, we investigated impact pure chemical (CFs) combined with compared CFs (100% CFs) and no (NFs) soil properties as well yield quality Chinese cabbage through meta-analysis. Results indicate that: (1) Compared NFs, can significantly improve increase nutrients. (2) CFs, fresh weight, number leaves, transverse diameter, leaf length, per plant, increases 8.54%, 6.6%, 9.905%, 8.42%, 10.03%; Meanwhile, (total amount above-ground parts produced) commercial (the portion that meets required standards is intended for sale) to by 10.08% 35.56%, respectively.
