What is sub surface irrigation?

Subsurface irrigation or sub irrigation allows the precise application of water, nutrients and other agro- chemicals directly to the root zone of plants.

Irrigating underground is one of the most efficient ways to water plants. Subsurface irrigation reduces evaporation, wind drift, over spray, vandalism and as such can save substantial amounts of water.

The depth and placement of the drip-line depends on the soil and need of the plant being irrigated. Water moves by capillary action through the soil, 150-750mm beneath the soil surface, forming a continuous wetted layer at the root zone.

Porous membrane hose

Porous membrane hoses are installed underground at a suitable depth and distance apart from each other depending on the soil conditions.

Due to a special quality of the type of hoses used in the system process, the pores react sensitively to gentle positive or negative pressure.

Each function can run automatically depending on results received by measuring equipment.

Different application for porous membrane hoses

- Positive pressure H²O or Air [supply of oxygen]

- Negative pressure H²O or Air [aspirate of oxygen]

Sub Surface Water Storage

The next generation of water storing soil improver has arrived.

This type of water savig humus is a novel soil additive with the special ability to store water and make it available to plants. Superabsorbers have already been used for a long time in the hygiene industry, especially for baby nappies, and are capable of storing large quantities of water.

The new development is: The mineral contents from volcanic rock flour, clay minerals and silicates supply important nutrient elements and at the same time provide for the structural stability of the granulate in soil. Unlike conventional, mixed granulates, these components in this particular humus are inseparably combined.

Benefits of subsurface water storage

  • Reduces plant watering by 50%
  • Reduces plant watering in combination with subsurface irrgation up to 80% (3l/m²/d)
  • Helps reduce soil compaction
  • Will not float to the surface
  • Increases soil aeration due to expansion and retraction
  • Lasts for several seasons
  • Increases water holding capacity especially in sandy soil
  • Reduces soil erosion
  • Reduces surface water run off
  • Improves survival rate of seedlings
  • Increases yield of agricultural products
  • Scientifically proven test results
