The use of surface irrigation in agriculture and gardening is not a new concept, but in the last 15 years there has been a greater awareness of its advantages and technologies have been added to overcome the problems encountered in the past.
Using underground irrigation we can benefit from all the advantages described below:
- Efficiency in the use of water: By keeping the surface dry, less water is lost through evaporation. In addition, the spherical distribution of moisture in underground irrigation is more efficient because it allows a greater volume of moisture at a lower radius.
- Root length: The roots penetrate deeper into the soil, allowing the root system to work in more stable conditions.
- Fertilizer application: Fertigation provides water and nutrients directly to the root system of the plant.
- Herbal control: By keeping the surface of the land dry, the germination of surface weed seeds is prevented, so there is less of this and the need to use herbicides is reduced.
- Soil infiltration: The surface crust created in some types of soils causes infiltration problems. Underground irrigation eliminates this phenomenon.
- Increase of the yield: Due to the increase of the irrigation and the absorption of fertilizers, even with smaller quantity of water and fertilizers.
- Water quality: Wastewater and other problematic sources can be used more safely when there is no contact between water (and its pathogens) and workers or leaves and fruits.
- Salinity control: The control of the salinity of the water and the soil is improved since no salts accumulate on the surface due to evaporation.
- Maintenance: Since the pipes are buried, they are less exposed to the adverse action of solar radiation and changes in environmental conditions such as drying / wet, cold / heat, so we expect the system to have a longer useful life. Mechanical equipment can move and work freely on the surface with less damage to the irrigation system and less soil compaction. In sufficiently deep installations it is even possible to plow.
- Disease control: By keeping the upper soil layer dry, diseases whose spread is aided by moisture between the cover of the plants and the soil are drastically reduced.
- Landscaping: The underground irrigation system allows irrigation without interfering with the visual and aesthetic design of parks and gardens.
- Security: The underground irrigation system offers greater protection of the equipment against vandalism and other damages, including animals.
