Replacement: 5L of Nano P can replace 100kg of single super phosphate. Application: Dosage: 8–16ml per liter of water for spraying, sprinkler, or drip irrigation. Timing: First application during soil preparation before sowing. Second application when the crop is 1 to 2 weeks old. Third application one week before flowering. Final application 1 to 2 weeks before harvesting. Disease Control: For diseases like downy mildew of grapes, fruit rot, root rot, citrus gummosis, and late blight of tomato, use 20–30ml per liter of water for spraying, sprinkler, or drip irrigation. Note: Other key nutrients, such as all water-soluble fertilizers, nitrogen, and trace elements, can be mixed with Nano P, except for calcium fertilizers and concentrated magnesium. In hydroponic systems, Nano P should typically be added to the B tank along with the sulfates and trace elements. Nano P has a buffering effect, helping to stabilize the pH of the solution at around 5.5.
