Multi-K – Potassium nitrate (13-0-46).
MAP – mono-ammonium phosphate (0-61-0).
Amm. Nit – Ammonium Nitrate (34-0-0).
Magnisal – Magnesium nitrate (10.8-0-0-15.8).
It is important to watch for boron and iron deficiencies. Where needed a single application of 0.1% boric acid or borax at 125 g/tree reduces the prportion of empty nuts.
Iron deficiency may be cured by applying Fe-EDDHA at 100 g/tree, in March.
