Plant physiologists and botanists have generally accepted the classic notion that the root is the sole organ concerned with the uptake of water and nutrients by plants. The leaf in contrast has been connected almost exclusively with the processes of photosynthesis and transpiration. The classic, and surprisingly current, concept has been that mineral substances absorbed through roots remained in the plant and only increased in quantity during the plant's life cycle. Organic substances synthesized by the plant, likewise, were thought to be utilized, degraded and not removed from the plant until death and degradation of the plant tissue occurred. Recently biologists have demonstrated that foliar absorption of nutrients is a universal phenomenon, but equally as important investigators have shown that plant foliage is capable of losing a significant amount of nutrients through the leaching action of rain and dew. The fact that plant parts can lose nutrients when in contact with aqueous solutions could be of great importance in plant science. Plant size, shape, nutrient content, fruit size, quality, and quantity, are but a few instances where the phenomenon of leaching may have a modifying influence. The leaf should be visualized as having a much larger role than just being concerned with photosynthesis and transpiration: a role concerned with the uptake and loss of inorganic and organic nutrients. In addition the ecological significance of leaching in the adaptation of plants to varied environments is incalculable.
