Product Name: Manganese Lignohumate
Product Code: GAC-MnLS
Primary Application: Chelated micronutrient fertilizer, soil buffer, and photosynthesis catalyst.
1. Product Overview
Manganese Lignohumate is a specialized organic micronutrient complex designed to optimize plant metabolism and correct stubborn nutrient deficiencies. Unlike harsh synthetic manganese salts, this formulation uses premium lignohumate (at a minimum 55% concentration) to naturally chelate the manganese ions. This organic pairing not only ensures the manganese stays highly soluble and bioavailable, but it also dramatically increases the soil’s Cation Exchange Capacity (CEC), neutralizing harsh pH zones to unlock trapped nutrients.

3. Key Agronomic Benefits
Manganese is a “hidden hunger” nutrient. Crops often suffer from a lack of it long before visual symptoms appear, leading to unexplained yield drops. Here is how this product tackles the problem:
- Supercharges Photosynthesis: Manganese is the core element responsible for splitting water molecules during photosynthesis. By supplying bioavailable manganese, you directly increase the crop’s ability to harvest light and generate harvestable energy.
- Maximizes Fertilizer Efficiency: The lignohumate base boasts a massive CEC. When applied alongside standard base fertilizers (like Urea, DAP, or MAP), it grabs onto those volatile nutrients and holds them in the root zone, significantly reducing runoff and leaching.
- Optimizes Nitrogen Uptake: Plants cannot properly metabolize nitrogen without adequate manganese. This product ensures that the expensive nitrogen you apply is actually converted into plant proteins rather than accumulating as toxic nitrates in the leaf tissue.
- Soil Structure & Buffering: Beyond feeding the plant, the organic complex physically improves soil aggregation. It buffers both highly acidic and highly alkaline soils, creating an ideal micro-environment where beneficial soil microbes can thrive and multiply.
4. Recommended Applications
Because it boasts a remarkably low water-insoluble rate (under 1%), GAC-MnLS dissolves cleanly and is perfectly suited for modern precision agriculture.
- Foliar Spraying: The fastest way to bypass soil-level nutrient lock-up. The lignohumate acts as an organic surfactant, helping the manganese spread evenly across the leaf surface and penetrate the cellular walls without causing phytotoxic burn.
- Soil & Drip Irrigation: Integrates flawlessly into fertigation setups. Consistent application through drip lines provides a steady release of chelated manganese directly to the active root hairs while simultaneously conditioning the surrounding soil.
- Base Fertilizer Blending: Can be safely mixed with dry bulk fertilizers to improve their overall efficiency and provide a slow-release micronutrient foundation for the growing season.
5. Packaging & Storage
- Standard supply is packed in 25 kg woven bags featuring a heavy-duty poly inner liner to prevent moisture ingress.
- Because the product is naturally hygroscopic (moisture-attracting), it should be stored in a cool, well-ventilated warehouse. Keep bags tightly closed when not actively mixing.
- Custom weight requirements and bulk packaging configurations are available based on customer demand.
