Chemical composition and impact of humic acid on citrus fruit growth: A molecular approach
Author(s): Miguel González
Abstract: Humic acid (HA), a key organic compound derived from decomposed plant and animal matter, plays a significant role in soil fertility and plant growth. Recent studies have demonstrated its potential to enhance plant growth and fruit yield, particularly in citrus crops. This review explores the chemical composition of humic acid and its molecular impacts on citrus fruit growth. Humic acid is primarily composed of fulvic acid, humic acid, and humin, which contribute to its ability to improve soil structure, water retention, and nutrient availability. Citrus fruits, known for their sensitivity to soil quality, benefit greatly from HA treatment, as it promotes root development, increases nutrient uptake, and enhances overall plant health. Through molecular mechanisms, humic acid activates various signaling pathways, influencing gene expression involved in stress resistance, nutrient metabolism, and growth regulation. In citrus plants, HA has been shown to improve leaf chlorophyll content, fruit size, and quality by enhancing photosynthesis and optimizing mineral nutrition. The effect of HA on citrus growth is also linked to its ability to mitigate environmental stressors such as drought, salinity, and disease. Despite the promising results, there is a need for further investigation into the optimal application methods, concentration, and timing for HA use in citrus farming. This review aims to consolidate the findings from multiple studies to provide a deeper understanding of how HA influences citrus fruit development at the molecular level, with the ultimate goal of improving crop productivity and sustainability in citrus cultivation.
