Photosynthetic values and inorganic nutrient contents of Sungai Ibai, Trengganu.

Photosynthetic rates and nutn'ent content measurements of subsurface water samples at four predetermined stations of Sungai Ibai in Trengganu indicated that the wet monsoon pen'od lowers the values of the former while increasing the ammonium nitrogen, nitrate nitrogen and dissolved oxyge...
