Effect
Increased micronutrient use efficiency
Algipower treated Grapevines, cv. Karaerik, grown in nutrient stress conditions hadn't a significant better uptake of N, P, K, Ca, Fe, Mg, Mn or Zn, but had a significant better Cu uptake compared to the untreated control plants. Under optimal nutrient conditions Algipower treated Grapevines had a significant better uptake of N, P, K, Ca, Cu, Fe, Mg, Mn and Zn compared to the untreated control in the same conditions
