What type of soil will have higher percentage of leaching and what could
be the causes? *
One reason that a portion of the soil samples was sifted through an additional sieve was to:
F minimize the amount of atmospheric gas contained in the samples.
G. prevent the bacteria from escaping the sample.
H. concentrate the amount of sand in the final samples
J.remove excess sand and pebbles from the samples.
