prolévání

Prolévání is a Czech noun derived from the verb prolévat, meaning to pour water over something or to flood with water. In everyday use it denotes the act of pouring water, and in horticulture and agriculture it most often refers to overwatering of plants or waterlogged soil. It can be intentional, as when irrigation is applied, or unintentional, due to heavy rainfall, irrigation mismanagement, or poor drainage.

Effects in plants: Excess moisture reduces soil oxygen, weakens roots, and can cause root rot and nutrient leaching. Symptoms include yellowing leaves, soft stems, slowed growth, and a damp, moldy soil surface.

Management and prevention: Use well-draining soil and containers; ensure drainage holes; water plants only after the top layer of soil has dried; tailor irrigation to plant species, climate, and container size; allow for drying periods and avoid leaving standing water; mulching can help regulate moisture and prevent rapid evaporation.

Other usage: In hydrology or land management prolévání may describe surface flooding and runoff after heavy rain, which can lead to erosion and nutrient loss. The term has a neutral connotation but is largely descriptive rather than a technical term, with more specific terms used in scientific contexts depending on the exact situation.
