Feldkapazität

Feldkapazität is a term primarily used in German-speaking regions to describe the capacity of a field, often in the context of agriculture or engineering. It refers to the maximum amount of something a given area can hold or sustain. In agriculture, Feldkapazität relates to the water-holding capacity of soil. It represents the maximum amount of water that a soil can retain after excess water has drained away under the influence of gravity. This is typically measured after a period of drainage, usually 24 to 72 hours, following a thorough wetting. Understanding Feldkapazität is crucial for irrigation management, as it helps determine how much water can be stored in the root zone and when re-irrigation is necessary to avoid drought stress or waterlogging. Beyond soil science, the concept can be applied more broadly. For instance, in urban planning, it might refer to the capacity of green spaces or parks within a developed area to absorb rainwater. In a more abstract sense, Feldkapazität could describe the maximum load or processing capability of a specific operational area. The precise meaning and measurement depend heavily on the context in which the term is used.
