Effects of Humistar on Plants

  • Increased white roots improves nutrient uptake and plant vigour
  • Better nutrient uptake means plant has thicker stem and improves flowering
  • Strong healthy plant naturally increases resistance to disease
  • Vigorous plant naturally increases resistance to disease

Effects of Humistar on Soil

  • Better uptake of Phosphorus, micro elements (e.g Fe, Mn, Cu, Zn) and other nutrients
  • Increases the cation Exchange capacity (CEC) of soil, results in less waste of applied nutrients
  • Improves soil structure wich enables better aeration of soil and increases soil water holding capacity
