Passive Hydroponic and Fertigation is a method of growing plant using mineral nutrient solutions instead of soil. A practically inert wicking medium transports water and fertilizer to the root by capillary action. Medium for drip irrigation like perlite, gravel or Rockwool which contains a multitude of free air spaces and thus delivers oxygen to the roots. terrestrial plants is grown with their roots in the nutrient solutions or in this mediums. In Fertigation or drip irrigation and Hydroponic farming, the type of fertilizer is the same. The Fertilizer is formulated depending on the plant type and it contains balanced and complete plant nutrients for growth, induce flowering and enhance fruiting. The fertilizer is normally a foliar or in a liquid form because it is transported through irrigation system to each plant.
The basic components of Nutrients in Hydroponic Fertilization that is widely used in Malaysia are:
The basic components of Nutrients in Hydroponic Fertilization that is widely used in Malaysia are:
- Nitrogen (N) - 280ppm
- Phosphorus (P) - 40ppm
- Potassium (K) -440ppm
- Calcium (Ca) - 200ppm
- Mg (Mg) - 55ppm
- Manganese (Mn) - 0.5ppm
- Ferum (Fe) - 2.5ppm
- Boron (B) - 0.5ppm
- Copper (Cu) - 0.02ppm
- Zink (Zn) - 0.05ppm
- Molybdenum (Mo) - 0.01ppm
*Sometimes, Humic Acid is also added to increase nutrients absorption by the roots. The pH of the nutrient stock is normally controlled at 6.1 (but it also depend on the pH of the media used).
