These are the three main nutrient fertilizers most commonly used for initial fertilization in field crops, vegetable and fruit cultivation. Since it contains nitrogen, phosphorus and potassium, it helps improve the fertility of the soil in soils that are deficient in these nutrients. The zinc it contains helps the root development of plants and has positive effects on yield and quality.

Round Granular 15‑15‑15+15SO3+Zn is a preferred fertilizer in fruit and vegetable cultivation, especially field crops such as corn, sunflower, sugar beet and potatoes. Its nitrogen, phosphorus and potassium contents are balanced. When the granules applied during subsoil fertilization dissolve with soil water, all three nutrients are easily absorbed by the plants by quickly coming into contact with the plant roots.
