2.2. Plant height, plant fresh weight and soil water content
The height of plant was measured from the stem where it
adjoins with the ground to the end of the longest leaf. This part
was then weighted as the fresh weight. The middle area of the
mixed soil was collecting by a spoon of 2.5 cm in diameter.
The soil was weighted as fresh weight (FW) and then dried at
80 C for 48 h as dry weight (DW). The soil water content
(%) was calculated using the following formula:
