Sensing of soil bulk density for more accurate carbon accounting

WitrynaDensity is the weight per unit volume of an object. Particle density is the density of the mineral particles that make up a soil; i.e., it excludes pore space and organic material. Particle density averages approximately 2.65 g/cc. e. A high bulk density indicates either compaction of the soil or high sand content. WitrynaDistribution. Organic soils comprise about 2% of the Earth's ice-free land surface. This includes 0.8% organic soils with permafrost. Organic soils can form in virtually any climate, even in arid areas, as long as water is available. They are most prevalent in the cool, humid boreal forest areas of northern Asia, Europe, and North America.
