For many years, wherever banana crop is grown, growers acquired experience fertilizing with Haifa products. Methods of application vary from country to country while advantages of using Haifa fertilizers are always beneficial.  Some of experimental results and field trials are shown in the following tables.

Growers who successfully adopted fertigation systems used Multi-K potassium nitrate in combination with other water-soluble fertilizers:

 

1. Santa Maria, Colombia - tropical conditions. Plant density: 1200-1800 mat/ha Expected yield: 45-60 MT/ha
