How to calculate relative compaction of soil
WebIn this video we graph the moisture content and dry unit weight in order to find the optimum moisture content. We examine how compaction is dependent on the ... WebWater content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood. Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation.

Web9 apr. 2024 · Typically, a good soil has 50% solids, 25% water and 25% air. Because a compacted soil has less pore space for air (porosity), the water infiltration will decrease, and runoff and soil erosion will increase. Soil compaction also increases resistance to root penetration, making it difficult for roots to grow deeper through the soil.
