| Insufficient of traditional fertilizer |
| In addition to NPK, crops need constant nutrients such as sulfur, magnesium, calcium, and micronutrients which are boron, copper, iron, manganese, zinc, nickel and molybdenum. Lack of any nutrient will affect production and yield of plant. |
| Fertilizers contribute to plant growth like bucket slats help to hold in water. If a nutrient is lacking, the plant can only utilize a portion of other nutrients. |
| Low efficiency of nitrogenapplication |
| 30% to 50% of N elements in common nitrogen fertilizers (urea and ammonium nitrate) are lost to air and water. In addition to causing huge losses, it also leads to serious environmental problems. |
