3
Consider scenario A:
A soil core with a volume of 150 cm3 is sampled from the field. The soil weighs 220g when directly
after collection from the field. The soil was brought back to the lab and saturated until all the pores
were filled and it weighed 275g. The soil was then allowed to drain and weighed 235g after all the
gravitational water drained out of the sample. After oven drying at 105 °C for 24 hours the sample
weighed 200g.
What is the percent moisture content by mass ( at field capacity?
Question 24
Consider scenarió A:
A soil core with a'volume of 150 cm is sampled from thç held. The soil weighrs 220g when directly
after collection from the field. The soil was brought back to the lalb and saturated until all the pores
were filled and it weighed 275g. The soil was then allowed to drain and weighed 235g after all the
gravitational water drained out of the sample. After oven drying at 105 "C for 24 hours the sample
weighed 200g.
What is the volume of the total pore space (in cm') in this soil?
