PK-FLOW 20
NPK 0-20-20
Description
Liquid PK fertiliser, 100% soluble, light brown, with a density of 1.39 kg/L and pH 7.49. Testing at an accredited laboratory measured 14.44% w/w (20.1% w/v) phosphorus pentoxide (P₂O₅) and 19.43% w/w (27.0% w/v) potassium oxide (K₂O). Phosphorus is involved in rooting and flowering; potassium, in fruit filling and quality. It is applied foliarly at 2-3 L/ha or through fertigation at 5-10 L/ha. Measured chloride: 2.74% w/w.
Key benefits
- ✓P₂O₅ 20% + K₂O 20% in one application
