Re: Article on banana fertilization and nutrient deficiencies
That actually does look like potassium. Mobile nutrient with yellowing and necrosis of the apical margin. Bananas use an enormous amount of potassium. Potassium is readily leached from sandy soils. If you are using 9-2-12 or 6-2-12 you almost need 1lbs per mat per month. If you were using something like black cow manure, you would need 100lbs per mat per year. I've got some sandy areas on my newer land and it seems like I am constantly putting out fertilizer.
