Experts from five countries recently traveled to Phnom Penh to learn more
about a new way to grow rice, one that requires lest chemicals and yields
Agriculturalists from Thailand,
Malaysia, Indonesia, China
and Pakistan spent five days
in Cambodia to review the
System of Rice Intensification, which is being developed in Cambodia by the
Center for Study and Development in Agriculture.
"The farmers in some of these countries in Asia, they are very interested with the experience we
have to encourage SRI," said Yong Sang Korma, director of the center,
which is known by its French acronym, CEDAC. "By following natural
principals, rice farms have higher production, while using their own resources
more effectively and expending less chemicals or pesticides."
SRI differs from traditional growth methods, but proponents
say the yield can be much greater. Under the system, rice fields are kept
moist, but not saturated, and rice stalks, whose seedlings are planted early
on, are spaced farther apart to promote the growth of roots.
South Tichaykunvuth, a farmer from Thailand, said
agriculture there is divided among families, who produce for themselves, and agro-businesses,
which farm for export abroad. Around 70 percent of Thai farmers use pesticides
on their crops, he said, a situation that is similar to Cambodia now.
"The use of chemicals can impact crop soil or the way
the produce tastes and smells," he said.

farmers in Southeast Asia was a reduction in

health," he said.
has nearly 3 million hectares of agricultural land, but much of it is farmed
through the use of chemicals. CEDAC works to encourage farmers to give up these
habits and turn to natural fertilizer and other methods.
Yim Kim Sean, secretary of state for the Ministry of Environment,
said he supports organizations educating people about agriculture. Only about
20 percent of Cambodia's
farmers know the negative impacts of chemical use on the environment and human
health, he said.
Cambodian has nearly 3 million heta of agriculture land in
daily profession Khmer people they likes to used chemical and pesticide ,and
these produce are imported from Thailand and Vietnam. Since 2000 CEDAC it
research agriculture locally have to encourage farmer to give up old habitat so
they turn to used normal fertilizer more.
