What is integrated nutrient management (INM)?

Integrated Nutrient Management (INM) is defined as a holistic approach that combines both organic and inorganic fertilizers to optimize nutrient use and improve soil fertility. This method recognizes that both organic amendments, such as compost and manure, and chemical fertilizers have essential roles in meeting the nutrient needs of crops. By leveraging the strengths of each type of nutrient source, INM enhances nutrient availability, reduces dependency on chemical fertilizers alone, and contributes to sustainable agricultural practices.

This approach improves soil health, enhances biodiversity, and can lead to better crop yields while minimizing environmental impacts, such as nutrient runoff. Integrating various sources allows for a more balanced nutrient supply, addressing the deficiencies often present in soils affected by intensive agriculture.

The incorrect options focus on either exclusive reliance on chemical fertilizers, which fails to consider the benefits of organic inputs, or they suggest the elimination of nutrients or a sole focus on organic farming. Such limitations do not align with the holistic nature of integrated nutrient management, which aims to utilize a diverse array of nutrient sources effectively.
