Ultrasol® Magsul is a source of sulfur (S) and magnesium (Mg), used in fertigation schemes to meet the plant's need for these secondary macronutrients.
Sulfur contributes to the formation of certain essential amino acids and proteins, while magnesium is an essential component of chlorophyll that enhances energy uptake and carbohydrate formation.
Ultrasol® Magsul can be mixed with all water-soluble fertilizers that are not calcium-containing components.
