The soil used was a sandy soil in the Yasothon series (Yt; fineloamy,
siliceous, isohypothermic, Oxic Paleustults), with a texture
comprising sand (93.9%), silt (4.2%) and clay (1.9%). The chemical
properties include pH 6.6, 0.7% organic matter and 0.04% total N.
Macro nutrients comprise 22 ppm of available P (Bray II method),
62 ppm of extractable K and 430 ppm of Ca.
