About this product
Agromaster Start Mini is a granular starter fertilizer with an NPK grade of 21-21-5 plus 2% MgO and 15% SO3 (6% S). Its high nitrogen and phosphorus content with reduced potassium, combined with sulphur and magnesium, promotes strong root system development in soils with medium to high phosphorus availability. The small granule size and the ICL Poly-S Release technology, which coats 40% of the nitrogen, feed young seeded crops — maize, sunflower, sugar beet — through the first vegetative stages. Place close to the seed at sowing.
