driplines

Driplines are components of drip irrigation systems used to deliver water directly to the plant root zone. A dripline is a length of poly tubing fitted with emitters, placed along rows, beds, or around individual plants and connected to a mainline and a pressure regulator. Emitters can be inline or attached as discrete micro-tubing segments, with flow rates typically ranging from 0.5 to 4 liters per hour, adjustable for crop type, soil moisture, and climate. Driplines may be buried at shallow depth, laid on the soil surface, or embedded in mulch to minimize evaporation. Design considerations include spacing between emitters, total length of line, soil infiltration rate, and filtration to prevent clogging. Proper pressure management and regular flushing are important to maintain even water distribution. Benefits include high water-use efficiency, reduced weed growth, and precision delivery that supports sustainable horticulture and agriculture. Driplines are commonly used in orchards, nurseries, greenhouses, and landscape irrigation.

In ecology and landscape management, the dripline of a tree or shrub is the circular line on the ground directly beneath the outer edge of the plant’s canopy. This area receives much of the rainfall that drips from the leaves and often corresponds to the plant’s superficial root zone. Maintenance, soil compaction, and construction inside the dripline can affect root health and tree vitality. The term is also used in hydrological studies to describe the distribution pattern of precipitation under a canopy.
