Summary
This narrative review, authored by researchers affiliated with Italian institutions and drawing on the broader international literature, examines humic substances as multifunctional components of soil organic matter with relevance to both ecological sustainability and agricultural practice. The paper likely synthesises evidence on how humic acids, fulvic acids, and humins influence soil fertility, plant physiology, and microbial dynamics, positioning humic substance applications as a bridge between ecosystem function and agronomic productivity. It appears to contribute to the growing body of literature advocating for biostimulant and organic amendment strategies as alternatives or complements to conventional fertilisation.
UK applicability
Whilst this review is international in scope and based primarily in an Italian research context, its findings on humic substances as soil amendments and biostimulants are broadly applicable to UK arable and horticultural systems, particularly given UK policy interest in regenerative practices and reducing synthetic fertiliser dependency post-Brexit.
Key measures
Soil organic matter content; plant growth parameters; nutrient uptake efficiency; soil microbial activity; carbon sequestration potential
Outcomes reported
The review likely examines the chemical properties, ecological roles, and agronomic effects of humic substances, including their influence on soil structure, nutrient availability, plant growth, and soil microbial communities. It may also assess their potential to reduce reliance on synthetic inputs and improve soil health under changing environmental conditions.
