Leaching fraction formula

WebPlant height of the plots having 20% leaching fraction was noted to be higher than those having 10 and 0% leaching fraction. The treatment T 7 demonstrated dominance over all the other treatments because of canal water with 20% leaching fraction. As the EC of irrigation water increased and the leaching fraction decreased plant height was reduced. WebSUMMARY The fraction (f) of surface-applied nitrate leached below any depth h cm in a uniform soil profile may be calculated from the equation where P is the quantity of water draining through the soil (in cm) and Vm is the percentage volumetric field capacity. The fraction of nitrate retained is then (1—f). This equation has been tested using published …
