Soil fertility and plant nutrition remained main pillars of agricultural sciences in twentieth century. However, due to recent interest in achievement of sustainability and restricted natural resources, importance of soil fertility and plant nutrition is expected to be increased many folds in twenty-first century. Therefore, increasing rice crop yield under such scenario will require judicious and efficient use of mineral sources of nutrient with combination of natural resources, recycling of bioavailable nutrients, and genetic modification of crops for efficient nutrient utilization. There is an increasing pressure on agricultural land to produce sufficient amount of food needed to feed the growing global population. The pressure is associated with changing weather patterns related to fluctuations in rainfall and temperature, supply of fertilizers inflating price associated with energy demand, which is very closely linked with weather patterns and reducing soil fertility. Increasing rice yield under these constraints will require a rational use of chemical fertilizers with increase the use of natural resources of nutrition, recycling of plant available nutrients, and an exploitation of the genetic potential of crop species to make efficient use of nutrients a key feature to establish smart plant nutrition management in the recent global climate change scenario.
