Soil water refers to the water present within the soil, existing in multiple forms and occupying various spaces within the soil profile. It includes water present in liquid form as soil moisture, water adsorbed to soil particles as bound water, and water within the pores and cracks of the soil as pore water. Soil water plays a crucial role in supporting plant growth, supplying moisture and nutrients to plants, facilitating microbial processes, and influencing the overall soil structure and properties.
