field capacity

The essential for plants water oozes rainfall (Rain, hail, sleet, snow) in the ground. A small proportion also comes from the surface precipitation (dew, ripening) formed by condensation, which directly through the surface just below the surface Tauwurzeln is recorded. The non-solid soil substance consists of pores of different sizes, which are filled with air and / or water. The pores can make up 30 to 60% of the total volume. Depending on the pore volume, the porosity - the ratio of the void - to the total volume results. All pores in dry soil are filled with air.

Water storage assets - graphic with soil structure and terms

The infiltrating water first displaces the air in the fine pores, until finally, when the soil is moist, air only remains in the coarse pores. Adhesive or capillary water is the water held against gravity, which sticks in pores smaller than 10 µm due to the surface tension of the water (meniscus = concave water surface). The amount of holding water that the soil can hold with its pores against gravity is called water capacity (WK) or field capacity (FK). It is strong from...
