__NOTOC__
The Micro-Tal system was developed by Ein-Tal Micro Drip Irrigation Ltd. in Israel. It is a gravity system that is adapted to take advantage of the benefits of the drip irrigation method without requiring an expensive water pressure system. The main feature of the Micro-Tal drip system is the low flow rates of 0.1–0.5 l/ h per emitter under low gravity pressure controlled by water heads up to 1 m. The very low flow rate (one-tenth of that of the ordinary drip) means that it takes 6–10 hours to supply the daily amount of irrigation water to a plant through the drip emitter. Another major difference with systems discussed earlier is the drip line, which is assembled by connecting in-line emitters with segments of 4-mm tubing. The gravity filter used in this system is also unique to the Micro-Tal.
 
'''Uses of a drum system'''<br>
 
A drum system covering 5 beds each 1 m wide and 15 m long can be used to grow 250 plants (tomato, egg plant and similar plants requiring a spacing of 60 cm along the plant rows); 500 plants (spinach, cabbage, kale, pepper and similar plants requiring a spacing of 30 cm along the plant rows); or 1,500 plants (onion, carrot and similar plants requiring a spacing of 10 cm). The drum system also offers water storage and control through a control valve, making it possible to fill the drum for irrigating at another time.
 
Six examples are presented: the KARI drum system from Kenya, the Waggon Wheel system from South Africa, the Family, Plastro and Micro-Tal systems from Israel, and the IDE drum used in India.
