Jordporositet
Jordporositet, also known as soil porosity, refers to the volume of voids or pores within a soil sample. It is a critical property that influences the soil's ability to retain water, support plant growth, and facilitate the movement of air and nutrients. Porosity is typically expressed as a percentage of the total soil volume that is occupied by pores.
The size and distribution of pores in soil can vary significantly, ranging from microscopic spaces between
1. Water retention: Porosity allows soil to hold water, which is crucial for plant growth and the
2. Aeration: Pores facilitate the movement of oxygen into the soil, supporting the respiration of plant roots
3. Nutrient availability: Pores enable the movement of nutrients, such as water-soluble minerals and organic compounds,
Jordporositet is influenced by various factors, including soil texture, structure, and organic matter content. Soils with
Measuring soil porosity can be challenging due to the complex nature of soil structure. Various methods are
Understanding and managing soil porosity is essential for sustainable agriculture, as it directly impacts crop productivity,
