For a recirculating system like NFT, the following nutrient protocol can be followed. It is important that a water test is conducted before using any solution and appropriate adjustments are made as per the analysis in the test report.
Nitrogen(Nitrate) – 160 ppm
Nitrogen (Ammonium) – 15ppm
Phosphate – 50ppm
Potassium – 210
Calcium – 190ppm
Magnesium – 50ppm.
Fe- 6ppm, Bo-0.5ppm, Mn-0.5ppm, Cu=0.1ppm, Mo, 0.05ppm, Zn, 0.08ppm
The micronutrient mix is mixed as above.
Mixing this will result in a solution of EC 1.8-2.0 provided the base water has less salinity. The ideal conductivity for strawberry is 1.2-1.5 during growth phase and 1.8-2.5 during fruiting phase. Higher the temperature, lesser the EC.
