These different particle sizes impact the size of the pores in the soil. Remember, air and water move through the pores. As you would imagine, coarse textured sandy soils with larger pores allow ...

Figure 3 illustrates how the magnitude of PAW changes with soil texture. Coarse textured soils (sands and loamy sands) have low PAW because the pore size distribution consists mainly of large ...

A higher bulk density means less porosity (space between soil particles), which affects aeration. The finer-textured silts and clays have more total pore space than coarse-textured sands although ...

Rainfall will wash nitrates downward through the soil profile where they may enter tiles or drainage channels and be lost for agricultural production. This is called leaching and is the major cause of ...
