What we supply
Three product families for fertilizer and soil products
Each product page lists the grade data from the current TDS, packing options and the documents we send.
Micronutrient lignosulfonates
Zinc, iron, manganese, copper, boron and molybdenum in a lignosulfonate complex, for soil and foliar products.
Humic and lignohumate
Humic acid, potassium humate, fulvic acid and lignohumates for soil conditioners and water-soluble fertilizers.

#Fertilizer processWhat the product doesGrades to evaluate
01NPK and compound granulationBinder for granule cohesion and lower dust in drum, pan or steam granulation.
02Organic-mineral granulesBinder for humic, mineral and organic blends that need strength through drying and storage.
03Water-soluble and fertigation productsWater-soluble dispersant and carrier. Check filtration, water hardness and tank-mix stability first.
04Micronutrient productsLignosulfonate complexes of Zn, Fe, Mn, Cu and B for soil and foliar formulas.
05Suspension concentrates and wettable powdersDispersant that keeps fine particles suspended in crop protection formulations.
06Soil conditionersLignin- and humic-derived organic carbon inputs for soil amendment products.

FAQ
Common questions
Something else? Send us your process details and we reply with a grade and the documents.
What documents come with each grade?
We send the TDS and SDS for the grade you are evaluating and a representative COA. Each shipped lot comes with its own COA.
Do you supply powder and liquid?
Most lignosulfonates are supplied as spray-dried powder. Sodium lignosulfonate is also available as a liquid for plants that dose solutions.
How are products packed?
Lignosulfonate powders ship in 20 or 25 kg woven bags with a polyethylene liner, or in 500 to 600 kg jumbo bags. Humates are also packed in 25 kg paper bags. Pallets and container loading are agreed per destination.
Can lignosulfonate micronutrients replace EDTA chelates?
They work differently. Lignosulfonate complexes bind metals less strongly than EDTA and are biodegradable. Which one fits depends on the crop, the soil pH and the formula. Our guide compares the two.
