According to the question, it asks about which type of soil has a higher bulk density under natural conditions and after compaction in two different scenarios.

Under natural conditions, coarse-textured soils generally have a lower bulk density compared to fine-textured soils. This is because coarse-textured soils have larger particle sizes and larger pore spaces between the particles, allowing for better drainage and air movement. As a result, the soil particles are less tightly packed, leading to a lower bulk density.

On the other hand, fine-textured soils, such as clay soils, have smaller particle sizes and smaller pore spaces. This causes the soil particles to be more tightly packed, resulting in a higher bulk density. The smaller pore spaces also lead to poorer drainage and reduced air movement within the soil.

However, after compaction, the scenario might change. Compaction is a process that involves increasing soil density by reducing pore spaces. When soils are compacted, fine-textured soils tend to experience a greater increase in bulk density compared to coarse-textured soils. This is because the smaller particles in fine-textured soils are easily compacted and have less resilience against compression.

In summary, under natural conditions, coarse-textured soils generally have a lower bulk density compared to fine-textured soils. However, after compaction, fine-textured soils tend to have a higher bulk density than coarse-textured soils due to their smaller particle sizes and higher susceptibility to compaction.
