[Mike Daniels - Professor of Environmental Management] One of the ways that we can become more efficient is to use conservation practices, and one of the unique conservation practices that's gaining a lot of popularity; it's known as a tailwater recovery system [Picture of a tailwater recovery system].
[Pictures showing field irrigation.] In any irrigation method, especially flood irrigating and furrow irrigating, it's very difficult to time when to stop the pumping, and you're gonna have water losses at the end of the field. [Pictures of a reservoir ditches and pumps.] Tailwater recovery system is set up to capture these losses and then we can store those in long, narrow - they look like long narrow ditches, but they're known as tailwater recovery systems. We can store that water, we can relift it with a pump and we can reuse that water for irrigation. So we're not just losing it and letting it drain into a ditch.
[Slide - Tailwater Recovery Advantages - Reduce Pumping $; Water Quality Impacts] Now this, this gives us two advantages, advantage number one is, we are reusing that water. So it does help reduce our cost of water, pumping cost, things like that. But it is very important to try to recycle and be as efficient as we can. Especially when we know that there is a set amount of water needed by the soybean crop. The second thing it does is anything draining off that field in terms of sediments, pesticides, nutrients; instead of cutting those loose to a ditch and ultimately to a stream or a bayou or a wetland, we are recovering those things in our tailwater recovery systems and then we're protecting water quality in that manner.
[Mike Daniels - Professor of Environmental Management] So, the nice thing about tailwater recovery systems is gives you a dual purpose of increasing your efficiency but also reducing any off-farm impacts on water quality.
