Most of my job is taking soil samples from various field sites.

Plant the same number of seeds in each soil sample.

The state environmental agency tested several water and soil samples from the site.

Their research started by collecting soil samples from all over the country.

The probe still held the original soil sample, that part of it not used in analysis.

He wanted to take soil samples on their property, maybe do a little digging.

The soil sample is first saturated under a specific head condition.

The soil sample exploded with the force of a large bomb.

No soil samples were taken before the paving took place.

Air drying can also preserve the soil sample for many months.
