The Effect of pH in the Tap Water on Nutrient Release from Slow Release Fertilizers

Abstract:

The objective of this research is to study the nutrient release behaviors on slow release fertilizer (Osmocote® N13:P13:K13, 3 month release formulation). The fertilizer was added into distilled water which adjusted pH of 6.5 and 7.5. The nutrient release behaviors were determined by collecting samples every 1 week and analyzed the nutrient contents in samples by scientific methods. As the result, for the total N release behavior, it may be considered that at lower pH condition tended to release more than that at higher one, for the P (shown by P₂O₅) and K (shown by K₂O) release behaviors may be high at high pH condition.
