*AS = Ammonium sulfate. This specific fertilizer is important in order to supply the need in SO3.

 

 

Manganese need (see above) should be best supplied as a foliar spray. Can be part of Maneb treatments against leaf diseases.
Sulphur applied in early spring as a compound fertilizer containing sulphate will generally give immediate response when lacking.
