AWD in the Field I am fully aware that I am an awkward turtle in photos, but here’s the proof that I’ve been to a paddy field! Roadside rice viewing en-route from Can Tho to An Giang. Site A. In the Thoai Son district, this here is the field where AWD is applied. Site A. And right along side is the control field; those four sticks indicating the location of the pani pipe. Site A. Dyke systems such as this can both retain water for flooded rice but also prevent unwanted flooding of AWD rice fields. Site B. In the Tri Ton district. Site C. Also in Tri Ton. Site C. Acid sulfate soils (present in this area) are unsuitable for the application of AWD
