Field capacity
Field capacity is the amount of soil moisture or water content held in the soil after excess water has drained away by gravity.
Также говорят: field water capacity, soil moisture capacity
Field capacity serves as the upper limit of water storage available for plant uptake. Understanding this value is essential for efficient irrigation scheduling and ensuring that crops remain within the optimal growth zone.
When soil water drops significantly below this capacity, plants experience physiological drought, limiting yield potential. A common mistake is over-irrigating beyond the field capacity, which causes nutrient leaching and anaerobic soil conditions, negatively impacting root health and soil aeration.
