Salt is an important coconut fertilizer

Chlorine is an important nutrient of coconut trees. And most soils are deficient, from a coconut perspective... so fertilize your coconuts with salt.

"From 1991 to 1997 farmers in the Philippines had fertilized more than 170,000 ha of coconut (approximately 18 M trees) with salt. This had resulted in an average relative yield increase of 125% over unfertilized coconuts."
