The calcium displacement method, explained
Raw cocopeat contains sodium and potassium ions that bind to the substrate. When you apply calcium-rich fertilizer, these ions compete — locking up your calcium and releasing toxic salts into the root zone.
Unbuffered cocopeat can cause osmotic stress, leaf margin burn, and crop failure. The calcium nitrate displacement method neutralises this — saturating exchange sites with calcium before planting, then flushing the displaced sodium out.
