POTASSSIUM SULPHATE
STRAIGHT FERTILIZER CONTAIN ESSENTIAL TOW MACRO NUTRIENTS
POTASSIUM & SULFATE
GENERAL INFORMATION
QUALI MAX® 0-0-52 supply POTASSIUM and SULFUR as main nutrients for plant growth and developments. They are dual nutrient fertilizer with an equivalent potassium content 52% POTASSIUM OXIDE (K2O), and 18% SULFATE (SO4). Those vital elements essential for whole plant activities from plantlet emergence till harvest and also post-harvest.
QUALI MAX® 0-0-52 improves crop yield and quality; making plants more resistant to drought, frost, disease attacked, improve the taste and appearance. It also increases resistance to deterioration during transport and storage.
