You are working in a lab and are tasked with determining the percent plant available water for a particular soil sample.    You take a field soil sample. The mass of your sample was 152g and it had 18.3% moisture by mass.   Then, you place the soil sample in your pressure plate extractor and determine that the soil sample weighs 164.2g when the moisture potential is -33kPa and 130.7g at -1500kPa.    What is the percent plant available moisture by mass of this soil sample? Please answer to one decimal place.

A permeability test was conducted on a saturated sample of coarse soil. The soil specimen has a 170 mm diameter and a length of 300 mm. hi and hz was 800 mm and 300 mm respectively. The permeabili this sample in cm/sec is 3.96 10 Time required to collect a volume equal to 350 cm at 20°C is: Select one: 4 min 5 min 4 sec 5 sec ge Teo
