Most of the soils have been degraded by the indiscriminate use of fertilizers, specifically the application of urea, requiring fertilizers to be applied together with products that improve nitrogen absorption; being zeolite, which helps to increase crop yields and decreasing at applied nitrogen dose. For the execution of this document, information was collected from books, magazines, newspapers, presentations, conferences, and information from websites that were subjected to the analysis-synthesis and paraphrase technique. The conclusions determined that the zeolite has the property of accumulating the irrigation water, to later release it little by little as the plant needs it. It retains minerals like potassium, calcium, magnesium and nitrogen; application rates vary with soil characteristics and other factors, and can be applied to localized soil or broadcast, also mixing zeolite with mineral fertilizers has proven to be a good option to increase the effectiveness of nitrogen or potassium fertilizers; the amounts of zeolite and fertilizer to be applied are calculated based on the characteristics of the soil and the needs of the crops. A widespread use ratio is to substitute 25% of the recommended nitrogen dose for the area with zeolite; The use of nitrogenous fertilizers, mixed with zeolite, allows replacing approximately 25% of nitrogen fertilization, which allows to increase the grain yield per unit area and the application of zeolite contributes as a soil improver and helps to reduce the production cost by hectare, in approximately 5%. |
