INM is an approach to farming that uses both organic and inorganic plant nutrients to correct nutrient imbalances in the soil, in order to attain higher crop productivity, prevent soil degradation, and safeguard future food supplies. It relies on nutrient conservation and application, new technologies to increase nutrient availability to plants, and the transfer of knowledge between farmers and researchers. INM's productivity benefits alone can be substantial. In Kenya, for example, the application of nitrogenous fertilizer on nitrogen-poor soils increased maize yields from 4.5 to 6.3 metric tons per hectare. Widespread adoption of INM could lead to significant increases in agricultural output in places like Africa, where about 86 percent of the countries lose more than 30 kilograms per hectare of the main soil nutrients every year.
