The term 'micro irrigation' describes a family of irrigation systems that apply water through small devices.

Micro irrigation is a low volume, low pressure irrigation system type. Includes all methods of frequent water application in small flow rates on or below the soil surface. In general micro irrigation systems are classified by the type of emitter used in the system, drip (trickle, tape, bubbler) or micro sprinkler (micro sprinklers, micro spray, micro jet, pulsator) irrigation technologies. 

A micro irrigation system delivers water to the crop using a network of mainlines, submains and lateral lines with emission points (drip, spray or sprinkler), spaced along their lengths. Each emitter or orifice applies a small, precisely controlled  water and/or nutrients uniformly directly to the root zone of the plant.

Wetted patterns under micro irrigation due to the manner in which water is applied only a portion of the soil surface and root zone of the total field is wetted. The exact shape of the wetted volume and moisture distribution depends on the soil texture, initial soil moisture and to some degree on the rate of water application.

Through good management of the micro irrigation system the root zone moisture content can be maintained near field capacity throughout the season providing a level of water and air balance close to optimum for plant growth.

Each device is designed to provide a wide selection of flow rates and wetting diameters.
