Drip irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters.
The plant absorbs carbon dioxide from the atmosphere, draws water up through its roots and uses light to photosyntze sugars, which it uses as food. It excretes oxygen as a by-product of the process. Without water, photosynthesis cannot take place.
