Slow Release Palm Fertiliser
Manufactured by a famous german company specifically for the commercial palm growers in Spain and Italy, it is the principal fertiliser used there. It is ideal for large pots and ground culture by top dressing. Releases over an 8-12 week period depending on amount of rainfall or watering.
The bonded isodur Nitrogen ensures that the root can use all the nitrogen over an 8 week period rather than the high leaching that occurs with soluble nitrogen. It is not salt based so does not harm the soil micro-organisms. Probably the best palm fertiliser available.
