Root Mist Technique - RMT

Known as aeroponics

The roots hang in

the air and aremisted with nutrientsolution for severalminutes (i.e. 1

minute on, 5 minoff)

This is an efficientand quick system for

growing short term

plants such as

lettuce, but not longterm plants Yudi 2006

Ukuran butiran nutrisi

sangat penting dalam

penyerapan oksigen

Semakin kecil : akarmudah menyerap nutrisi

Semakin besar : akan

jatuh sebelum diserapoleh akar

Umumnya ukuran: 20-100

microns

Plants are grown in inertor organic material andthe nutrient solution arefed around the root

system 6-7 times a day,in drops or trickles.

Recovery Drip System isthe excess nutrientsolution that runs off is

collected back in thereservoir for re-use.

The Non-Recovery DripSystem does not collectthe run off.

The pump unit takes water fromthe source and provides the rightpressure for delivery into the pipe

system The control head consists of

valves to control the dischargeand pressure in the entire system. It may content filters : screen,

graded sand Also fertilizer or nutrient tank Will be one of major advantages of

drip irrigation over other



22/28

Mainlines, submains andlaterals supply water fromthe control head into thefields. They are usuallymade from PVC Lateral pipes

are usually 13-32 mmdiameter. Emitters or drippers are

devices used to control thedischarge of water from thelateral to the plants.
