Agriculture committee  According to our data, it costs about $1,000 a year for every 10 acres.

Agriculture committee  When the land is slightly more sloped, the structures have to be installed in tiers.

Agriculture committee  The only way to drain very sloped land is to have control structures at different levels that will drain the first part and then slowly take it down to the next part. We haven't done this because here in the South Nation area, the land is very flat. I believe research like that

Agriculture committee  Very much so. Like I mentioned, in 2005 only one person was interested in doing this process. Slowly, with our results and making producers see that there's no bad effect from control structures, they're becoming happier to accept the structures.

Agriculture committee  I haven't been looking that closely at the project. I believe the results are there to show that satellite works. They were studying our field sites, and they had good results coming out of it. I would say it's another tool to—

Agriculture committee  Not really. Someone who works on that project spoke to me about it a bit two days ago, but I can't give you any details.

Agriculture committee  I'm not sure.

Agriculture committee  I don't know the exact amount. However, I can tell you that the amount required to drain a 10-acre field is approximately $1,000.

Agriculture committee  Yes, exactly. The structures are not the only thing that matter, it also depends on precipitation. If it does not rain, there won't be any water to retain. It works well some years, and not so well other years. That is why we said that the yield improvement ranged from 3% to 8%.

Agriculture committee  There are several sizes. The box can drain a larger field, or a larger area. To understand better, I invite you to look at the second slide. We install a structure at the end of the drain pipe and we put in traps. We can drop it in as far as the roots, that is to say to 30 or 6

Agriculture committee  If you are asking for my advice, I would say yes, especially since climate change leads to a variation in water levels. We have had good results. Unless I am mistaken, producers like Mr. Laflèche are very happy with the results.

Agriculture committee  Good afternoon, members of the committee. I will briefly present on controlled tile drainage and research conducted by Agriculture Canada with producers such as Mr. Laflèche and the South Nation watershed. I completed my master's degree on this in 2009 at the University of Ottaw
