Geoflow - Model SDI -Ultimate Subsurface Irrigation System
Traditional drip irrigation is found above ground, now with the invention of ROOTGUARD¹, the lines can be buried below ground for a long, trouble-free life. Subsurface irrigation allows the precise application of water, nutrients and other agro- chemicals directly to the root zone of plants. This allows the farmer to optimize the growing environment and leads to higher quality and quantity crop yields. By stressing product quality, dependability and ease of use, Geoflow is providing the best products available in the Subsurface irrigation market today.
The depth and placement of subsurface driplines is determined by the soil composition and the crop needs. An efficient installation has water moving by capillary action at a depth of 4 to 30 inches beneath the surface, forming a continuous wetted area along the plant rows. Frequent irrigation cycles (several times daily) maximize capilllary action and minimize water surfacing.

Comparison table
Given the same amount of water, subsurface drip irrigation covers a 46% larger wetted colume of soil than a surface drip system. This decreases the saturation point of the soil, which not only leaves room for more air, but also improves the capillary movement of water and decreases the water lost to deep percolation.
