NPK 18:4:18
NPK 18:4:18
Complex NPK fertilisers with high nitrogen and potassium content.
Contain all necessary nutrients in one granule.
Suitable for all crops and soils (especially phosphorus-rich soils). Particularly effective as main and at-planting fertiliser for all crops, and as supplemental fertiliser during tillage.
Category: Fertilizers
Sub Category: Complex fertilizers
- Description
Advantages
- as a balanced nitrogen source, containing both forms of nitrogen (nitrate and ammonium). A nitrate form is essential to nutrition of fast-growing crops and ensures good root development, while the ammonium form is important to maintain a stable supply of nitrogen.
- With its consistent nutrient composition in each granule, this complex NPK fertiliser ensures uniform distribution of all nutrients across the field.
- Optimal for soils with a high phosphorus content.
- Recommended for perennial crops, fruit, coffee, cocoa, sugarcane, vegetables.
- Suitable for top-dressing during inter-row tillage.
