NPK 5:10:10 that means 5% nitrogen, 10% phosphorus and 10% potassium. NPK 5:10:10 can be used for yams farming.
This fertilizer can be applied by side dressing, top dressing or through Fertigation.
NPK 20:10:10 has 20% nitrogen, 10% phosphorus and 10% potassium. This type of NPK fertilizer is usually used during the vegetative stage of the yam plants. This fertilizer can be applied by side dressing, top dressing or through Fertigation.
NPK 12:12:17 fertilizer has 12% nitrogen, 12% phosphorus and 17% potassium. This fertilizer can be applied by side dressing, top dressing or through Fertigation
