Inorganic and organic metabolies may be leached from the foliage of many plants by aqueous solutions, including rain, dew and mist. Leaching is a widespread natural phenomenon and 61 metabolites have been characterized in plant leachates. When a plant is leached intermittently for 18 consecutive days, the loss of a particular nutrient may be 3 to 8 times the initial concentration of that nutrient in the leaves. The nutrients lost by leaching are replenished by a redistribution of nutrients from other plant parts and by root uptake and translocation from the root medium. Thus, it would seem that the rate of root uptake and translocation of nutrients to the stems and foliage should be greater in a plant which was being leached than in a similar plant which was not being leached.
