Rizen™ 7-28-3 is Fertizona’s basic NPK starter fertilizer formula. It is formulated with a pH of slightly below 5 limiting the possibility of free ammonia damage to seedlings.
This high Phosphorus, 2:1 ratio of Nitrogen to Potassium SmartBlend™, is compatible with most minor elements and nutrient enhancers. Rizen 7-28-3 is non-phototoxic and can be mixed with imidacloprid and most other pesticides and fertilizers, but jar testing is recommended.
Rizen 7-28-3, injected 2–3 inches below the seed line at planting will give a quicker and more vigorous start to young seedlings.
