Reduce flooding risks against heavy rain scenarios.
Poor water drainage brings an increase of the flooding risk during periods of excesive rainfalls. This factor endangers the crops that are ready to be collected particularly during heavy rainfalls periods. A decrease in the harvest yield will depend on the number of days the land has been flooded (in this aspect a good drainage is a crucial factor), crop type and stage of growth when flooding happens. As an example, the following table is shown, presenting an estimated percentual reduction of harvest according to different numbers of flooding days.
|HARVEST YIELD REDUCTION %|
|NUMBER OF FLOODING DAYS|
Drenotube® contributes to a fast draining of the flooded fields and therefore reduces decisively the risk of suffering losses in the crop.
Groundwater level control.
Establishment of a subsurface drainage allows to control the maximum height of the groundwater during periods of high precipitation. This aspect ensure a part of soil remaining unsaturated of water resulting in a proper leaching and disposal of salts, optimal root aireation during the rainy periods and a high root grow that later allow a better development of the plant.
YIELD OF SOME CROPS DEPENDING ON THE GROUNDWATER LEVEL (%)
||GROUDWATER LEVEL DEPTH (cm)|
The above table shows higher yields when groundwater level is between 60 and 150 cm deep in reference to the surface.
Other benefits are: more accesibility to the area, shorter crop periods, more permeable soil, and a slight increase in the soil temperature, a benefit that implies faster crop growth.
