Fulltec UltraZinc™ is a complete nutritional blend which supplies the nutrients that can limit production when they are needed in greater quantity than the soil can provide. The product works considering “Justus Von Liebig’s law of minimum” which states that yield is proportional to the amount of the most limiting nutrient, whichever nutrient it may be.
