Buystar Extra NK 14-0-34 + 4 MgO is a microcrystalline fertigator with total and immediate solubility that provides an elevated amount of Potassium and Magnesium. Potassium shifts the plant’s metabolism towards reproductive development, limiting excessive growth, and directly affects the quality of the final production. Furthermore, by adjusting the osmotic pressure, Potassium accompanies the development of the fruit, improving cell expansion and the qualitative characteristics. Magnesium plays an intense greenifying role that stimulates and makes photosynthesis and the accumulation of organoleptic compounds more efficient. Finally, the RyZea technology enhances plant metabolism, stimulates the biological activity and enzymatic processes of the soil and increases the bioavailability of soil nutrients.
