PF = Polyfeed drip of the different analyses indicated.
Multi-K = 13-0-46 (Potassium nitrate, soluble)
Note: Rate of application should be adjusted according to soil and leaf analysis.

 

Additional to the fertilization by fertigation, foliar feeding is recommended as complementary treatments, as follows:

Fertilizers

Rate

2 months after harvest Magnisal .4 - 0.5% by 2-3 sprays in 2 weeks intervals Induction of new leaves, Improved health
2 months before flowering MKP or MAP 0.5% by 3-5 sprays in 2 weeks intervals Flower initiation
1 month after fruit set Multi-K + Magnisal 1-2%, by 6-8 sprays in 2 weeks intervals Increases fruit size & shape
0.25-0.5% by 2-4 sprays in 2 weeks intervals Increases total solids in fruit

 

 

Magnisal = Magnesium nitrate, 11-0-0 +15.8 MgO, a fully soluble fertilizer.
MKP = mono-potassium phosphate, 0-52-34, a fully soluble fertilizer.
MAP = mono-ammonium phosphate, 12-61-0, a fully soluble fertilizer.
