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)

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

Drip Irrigation Technique
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.

Drip Irrigation Technique
Growing medium shouldbe clean and sterile
Reuse growing mediumshould be sterilized
Plants are irrigatedaccording on climatecondition
Amount of nutrient
solution is equal withcrop water requirementthat represented by ETc

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

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.
