In a world
confronted with the dual challenges of feeding a growing global population and
addressing environmental concerns, plant biostimulants have emerged as a
promising avenue to enhance crop productivity and sustainability. This study
elucidates the potential of humic substances as a sustainable and eco-friendly
solution to the challenges facing modern agriculture, while also addressing
associated limitations to promote environmentally friendly agricultural
practices. Humic substances, including fulvic acid, humic acid, and humin,
derived from the decomposition of plant and animal matter in soil and
sediments, have gained attention for their effectiveness as plant biostimulants.
These compounds, abundant in carbon (C) and characterized by complex molecular
structures, play a pivotal role in promoting plant growth and development.
Additionally, the advantages of utilizing humic substances may align with the
goals of sustainable agriculture, as evidenced by their ability to improve
nutrient absorption, enhance soil health, and bolster stress resilience in
plants. However, challenges and limitations, such as variations in commercial
product quality, application methods, and associated costs, must be addressed
to maximize the benefits of humic substances in agriculture. Developing
standardized guidelines for their application emerges as a crucial step towards
cultivating a more resilient and environmentally responsible food production
system to meet the demands of the 21st-century global population.
