We have been marketing a sub-irrigation system that saves on average 50% of irrigation water, saves on fertilizers as it is contained, plant performance and yield is improved as roots are able to take what they need,not what we give them, when irrigating from the top. Containment of the fertilizers etc, also means less contamination, creating of algae blooms in localized rivers streams and ground water aquifers.You also get better soil management and less erosion. It might be seen to be expensive, but, just look around the corner, and tell me the "true cost of not" taking action or being a bit more innovative. JT
