Water-soluble fertilisers dissolve fully in water, delivering nutrients in the ionic form plants actually take up. Because no mineralisation or weathering step is required, they suit fertigation, hydroponics, foliar correction and precision solid application alike. This category covers straight nutrient salts — magnesium and zinc sulphates among them — supplying secondary nutrients and micronutrients in grades that differ by hydration state, purity and particle size. Choosing between them comes down to three practical variables: contained nutrient per tonne, rate of dissolution, and the application equipment the product must pass through.
