The bulk density of a soil, is the ratio between the mass and volume of a fraction of soil, the most important is that the volume fraction have included soil air. This is very important because in the porous part is where there is water movement and more movement of the roots becoming root penetration, among other things, like the movement of nutrients or nutrient uptake by the roots.

Dear colleages.

I have a question and may be somebody can help me. The Bulk density coefficient ( SBDM ) in the soil file, is the soil density including coarse elements or without them? I'm not sure which density I should write.

Thank you very much
Best regards
Maria
