Soil sampling for bulk density measurement

Knowing soil bulk density is a part of monitoring the soil resource in planted forests. It is used to assess changes in soil physical properties and to calculate the nutrient content of the soil (bulk density x nutrient concentration).

Hi
Thank you for this helpful video
I have a question, regarding the rock part, shouldn't why put the rock part inside the core instead of the sampling bag to prevent soil to enter in the place of the rock part in the core?
I mean the sample now is the volume of the core + the volume of the rock part

Thanks for getting in touch. From our science team: "Sample the core to the exact depth increment required. Therefore not over sampling the soil just to fill the core volume. This will result in the correct mass of soil sampled regardless if the rock is in the bag or put back into the core."
