Zeolite LTA is a synthetic zeolite characterized by a unique crystalline structure, possessing a high cation exchange capacity that enhances nutrient retention, moisture retention, and soil structure improvement. For the method of study, seven different treatments including three control treatments with no zeolite added and four treatments with zeolite added per plant in 1000 g of soil were analyzed to determine the optimum ratio of soil and fertilizer.
