Which type of soil typically has large pore spaces?

Sandy soils are characterized by their relatively large particle size, which results in larger pore spaces between the individual soil particles. These larger pores allow for better drainage and aeration compared to other soil types. Sandy soils typically have a lower water-holding capacity, which means water drains through them quickly. This can be advantageous in certain agricultural practices where excess moisture needs to be managed, but it can also require more frequent irrigation, as nutrients and moisture can move through the soil profile rapidly.

In contrast, clay soils have very small particles that create tiny pore spaces, leading to poor drainage and aeration. Silt soils, while also having a finer texture than sandy soils, have intermediate pore sizes and moderate drainage characteristics. Peaty soils, rich in organic matter, tend to have a high moisture-holding capacity and also do not feature the large pore spaces typical of sandy soils. Thus, sandy soils are the optimal choice when identifying soils with large pore spaces.
