Humans have been altering the world's biogeochemical cycles for many years to ensure food and energy security. Many of these anthropogenic activities modified the nutrient cycles of major and micro nutrients of worlds. The scale of these changes has massively accelerated since the industrial revolution throwing the equilibrium into disarray. Mineral nutrients such as nitrogen, phosphorous potassium, calcium, magnesium, sulphur, and other micronutrients are essential for plant growth and crop production. Presently, we face a glaring contrast of insufficient use of nutrients on one hand and excessive use on another. Nutrients Use efficiency represents a key indicator to assess progress towards better nutrient management. Smart fertilizers could promote nutrient absorption by crops and enhance fertilizer use efficiency during the growing season. Compared with conventional uncoated fertilizers, the multifunctional environmental smart fertilizers can sustain release nutrients which can significantly reduce the costs of repeated application. On the other hand, smart fertilizers would reduce losses of nutrients, prolong fertilizer cycles, and enhance effective nutrient uptake by crops. These can substantially decrease the risk of environmental pollution. Taking into account these economic aspects and the extremely important environmental aspects, the use of smart fertilizers would benefit farmers, and is also good for the protection of environment, which may be enough to outweigh the cost.
