20-20-20 PLUS All-Purpose Water-Soluble NPK Blend South Africa

About the 20-20-20 PLUS Blend

The 20-20-20 PLUS NPK blend provides an equal ratio of nitrogen, phosphorus, and potassium — each at 20% — making it one of the most versatile water-soluble fertilizers available. Its balanced formulation is suitable for a wide range of crops where a single blend is needed to cover multiple nutrient requirements without complex feeding programs. The PLUS designation includes a chelated micronutrient package covering iron, manganese, zinc, copper, and boron for complete crop nutrition.

Application in Crop Programs

The 20-20-20 blend is widely used in diversified farm operations and mixed-crop greenhouse facilities where simplicity is valued. It is a practical choice when the same irrigation system serves multiple crops or growth stages, as the balanced formulation performs reasonably well across different crop types. It is also used in nursery propagation, containerised production, and in programs where soil testing indicates broadly deficient nutrient status without a clear single-nutrient priority. Growers with more specialised programs often use stage-specific blends (13-40-13, 19-6-20, 15-5-30) instead.
