Progress Report from E&R Base in Thailand: June 2012
The regular water quality monitoring from 3 water sources:
Irrigation canal, natural canal and ponds in Kasetsart University, Kamphaeng Saen Campus.
Assumption of this research is water quality has the effects on plant growth and yield. There for it is necessary to investigate the water qualities from each locations or sources. Variation water sources for agriculture are found in Thailand such as from the dam pass-through irrigation canal (photo 1) or natural canal (photo 2) or pond (photo 3). Aerial photo of sampling points are shown in Photo 4. Simple qualities such as pH,Electrical Conductivity (EC), and temperature are measuring.
Four sampling points were selected from each water sources and four sampling were taken for measuring the qualities. The water EC from irrigation and natural canal did not change over season . Water EC from ponds in KU was showed different and EC higher than other sours. Water pH from each sours were not different in each month. The seasonal trend had shown similar in each source. The seasonal trend showed decrease from July, 2011 until May, 2012. The reason of decreasing trend was not clear. The water pH of 3 sources is fluctuation during 5.09 -5.85.
