Nutrient Management Strategies for Water and Nutrient Saving in Substrate Soilless Culture Under Protected Cultivation

In soilless farming, nutrients solution plays a significant role for plant growth and food quality. Knowledge of accurate nutrient selection and its management is always challenging for crop growers in soilless systems. Further, there is a growing need to recirculate and reuse drained solutions in order to decrease environmental issues and economicEnvironmenteconomic expenses. However, one of the weakest points in soilless systems is the lack of information on managing the nutrient solution. Therefore, this chapter describes the nutrient selection and compositions, recycling of drained nutrient solution, frequency of fertigation, types of fertigation system, and their nutrient management in soilless system under protected cultivation.
