Sodium humate

Sodium humate (CAS 68131-04-4) is the sodium salt form of humic acids, derived from leonardite, lignite, or peat through alkaline extraction. It functions as a chelating and buffering agent across agriculture and water treatment.

The compound improves nutrient availability and stabilizes solution chemistry in commercial-scale operations. In agriculture, it is applied to soils and irrigation systems to chelate micronutrients such as iron, zinc, and manganese.

This process keeps minerals in plant-available form rather than locked in insoluble complexes. It is incorporated into liquid fertilizers, foliar sprays, and soil conditioners to improve cation exchange capacity.

The material supports root uptake efficiency and enhances overall soil health. In water treatment, it acts as a flocculant aid and pH buffer, helping to manage organic load and stabilize treatment chemistry.

It is frequently used in municipal and industrial effluent systems for chemical stabilization. Feed-grade applications use it as a gut-conditioning additive in livestock and poultry diets for health management.

Its buffering capacity supports digestive tract pH management in commercial animal husbandry. The product is supplied as a black powder, granules, or flakes, with solubility and humic acid content varying by grade.

Standard commercial grades are defined by humic acid content, typically ranging from 50% to 85% on a dry basis. Agricultural, feed-grade, and technical grades are available depending on the specific industry needs.

Specifications vary by intended application and regional regulatory requirements. This versatile chemical remains a staple for industrial, agricultural, and environmental remediation projects worldwide.
