The researchers studied different types of soil in a lowland area to understand their properties like texture, density, water content, and organic matter. They found that the amount of organic matter in the soil affected its water-holding capacity and porosity. Soils with more organic matter had better water retention and more air pores. The study showed that the distribution of soil pores in these soils was not ideal, with some areas having limited air pores. Overall, the presence of organic subsoil with high retention capacity played a crucial role in the water resources of these soils.
