Soil, Fertilizer & WateringHow is leaching fraction calculated for an irrigated mango nursery pot?
Divide the drainage volume by the volume entering the substrate during the same irrigation event, then express the result as a percentage. For example, 1 cup draining from 5 cups applied gives a 20 percent leaching fraction. That illustrates the calculation, not a recommended target. Select a target suited to water quality, substrate, and crop conditions, then verify the response.
