Applications & Use Cases
- ▸ Soil conditioner and biostimulant that improves cation exchange capacity, soil structure, and water retention, releasing bound nutrients to plant roots in row-crop and horticultural agriculture.
- ▸ Fully water-soluble humate concentrate for fertigation and foliar feed programs, where its carboxyl and phenolic groups chelate micronutrients such as iron, zinc, and manganese to keep them plant-available.
- ▸ Heavy-metal sequestrant in water and wastewater treatment, complexing dissolved metal ions into insoluble humate chelates to reduce toxicity in aquaculture and effluent streams.
- ▸ Binder and pellet-conditioning aid in industrial applications such as foundry sand, ceramics, and feed pelleting, exploiting its natural tackiness and film-forming behavior.
- ▸ Animal feed additive grade used as a non-nutritive supplement that binds mycotoxins and heavy metals in the gut; note this is a separate feed/aquaculture grade distinct from the technical industrial grade.
