Made from animal and plant proteins by an advanced process, this upgraded grade of A80 contains free amino acids ≥80% and total amino acids ≥83%. Its 17 amino acids are well balanced, it is chloride-free and heavy metals are below 0.5 ppm (as Pb). Process optimisation reduces water-insoluble matter to ≤0.5% and raises solubility (25°C) to ≥20.0 g/100mL, giving clearer solutions and less precipitation in high-concentration formulations - ideal for concentrated liquid fertilisers, aerial application and drip or sprinkler irrigation systems. Total nitrogen ≥13.0%, moisture ≤6.0%, pH (1:250) 4-8 and sulphur ≤3.0 g/100g.
