How does soil moisture affect compaction?
Soil moisture is everything. Water helps soil particles slide and rearrange themselves when compacted. There is an ‘optimum moisture’ point where you achieve maximum density.
- If the soil is too dry: The particles rub against each other a lot and are harder to compact. You will need more passes and more effort.
- If the soil is too wet: Water takes up the space that soil particles should fill. Since water cannot be compressed, it will prevent you from achieving good density.
