Drainage for farming applications

Farms can suffer from several water issues, either waterlogging or flooding in clay soils, or salination from the water table. Capiphon™ drainage improves these issues in agricultural settings.

Saturated ground

Poor soils don’t cope well with high rainfall –water retention can saturate the soil which damages plants and affects plant growth.

High clay content, low permeability, top-soils and sub-soils of low quality can all lead to soggy top-soil in cool growing seasons. Sub-soils may be dense and impermeable, such that the volume of water on the surface can’t move away without causing erosion or takes ages to evaporate, leaving minerals leached onto the surface of the soil. This is most common in the southern hemisphere in the colder months of July and August when there is slower evaporation.

When the ground is soggy, the aeration of the soil is lower, nitrogen is lost from the soil and the leaves of plants can yellow, restricting their healthy growth. Damage also occurs to the roots of the plants – water retention in the soil actually inhibits the roots’ ability to absorb nutrients and (ironically) water. These problems lie with the soil and can occur whether the ground is flat or on a slope.

Soil Salinity

Dissolved minerals are carried through soil by water. When water is drawn to the surface of the soil (which may be caused by rising water tables, or poor surface drainage) the evaporation leaves a concentrated amount of these minerals behind. Sometimes this “salty” appearance is visible on the surface but more often than not the damage occurs beneath the surface where it impacts plant roots.

In this installation, Capiphon™ drainage was installed at low cost throughout an Olive grove and successfully resolved the problems that had been caused by salinity in the soils. The farm had shown signs of salinity, with ground grass cover dying off and trees losing their leaves. With good drainage, these problems no longer occurred.
