Brian & Darren go over what Drain Tile is, and how it helps the environment.

Gabe Brown doesn't seem to have this issue on his no till farm.

eliminate the ethanol boondoggle and watch the price of corn plummet
-
sure- don't allow the water to percolate down to the aquifers

Agricultural lands tiling may and may not be environmental friendly, it depends on how it is practiced and what are other practices such as fertilization on the lands. Just for example, Algal bloom in the Lake Erie has been linked to tiling mainly. Research are ongoing to determine the role of residential lawn fertilization on algal bloom. Please check your facts well before advertising.

jason, you have no idea what your talking about. What your talking about has already been proven is coming from fertilizer used in urban settings used to feed lawns, and golf courses. Farm land is not the reason for polluting the rivers or gulf
-
would it be work for flood irrigation.we see problems during moonsoon which affects vegetable crops

Tiling is not environmentally friendly. Yes it prevents surface runoff, but all those chemical carried above ground are transported in a pipe underground. At least when it flows above ground there is more filtration of the chemicals then when it flows through a plastic pipe. Tile drains and No till operations are the leading causes of Eutrophication in the Great Lakes Basin of North America.

It's farm drain flow not tiling.....

Tiling is not a term used in the UK.

Good machines

my god, what a haircut has the guy on the left.

At the very least, do your damndest to make sure you are using best construction practices. Even trained and licensed contractors can get into bad habits. ALWAYS install the system from the outlet upwards and construct laterals from the main upwards and never in the reverse direction. Also, there is a best method for cutting and making connections of a lateral to a main. Don't use quick methods such as slitting the back of a tee and placing it over a hole in the main. Possibly get together with a university ag extension person and create a learning group like a barn building bee to get some local experience in the field. There are graded licensing and instruction systems that could be used. An interested person could get some experience in the summer or fall.

People usually emphasize the removal of excess water in the soil because of the use of the word "drainage" but really what should be emphasized is that one is seeking to increase the amount of air in the soil to maximise root respiration like you do tuning a carburetor. Roots stop growing when the amount of air in the soil is too low above the water table. There is a lot of misunderstanding about subsurface drainage, how roots work and soil water.

There are reasons why one should call a licensed plumber instead of trying to figure out what is wrong with a kitchen sink drain. The same goes for do-it-your-self tile drainage. Tiiling is expensive and a small error in the installation can negate much of the system. It is very important to have equipment that controls the grade of the pipe being installed. I know a case in which an agricultural producer with no familiarity with subsurface drainage had a person install pipe with a D8 caterpillar tractor and the pipe went off grade near the outlet due to a sharp j turn in the line. Pipes tend to rise going around a curve if not properly controlled and if a laser plane is used, a turn can result in a loss of grade as well. The tile system did not work and the agricultural producer did not know why and concluded that tile doesn't work. A person with subsurface drainage experience as an agricultural producer in another area where it was common, looked into the matter on hearing about it and did some digging along the line. The line was working perfectly up to where the pipe went off grade.
When installing pipe with a drainage plow there are also things like buried rocks that can put the tile off grade (too high or too low) and even with special linkages and attitude control of the toe and heel of the shoe, the affected section of pipe near the rock needs to be inspected and corrected if necessary to make sure it is on grade. -
sewardandandlawn: The main thing that prevents sedimentation is the water velocity which is determined by the grade of the tile. Sedimentation will occur if the water flowing through the tile slows down. The minimum grade for clear draining, 4 in. perforated tile is about .15% (about 1.8 in. per 100 feet). Contractors can consult tables regarding minimum grade for clear draining pipe of various diameters and wall types. E.g. smooth wall tile will have less turbulence and drain clear at a smaller grade. For some soil types, there are geotextiles/socks of various grades that can be placed around the tile at the time of manufacture.

stop being so ignorant

50cents a foot....man I wish a mofo would quote some bull like that. I blame Obama.

good for the environment?? haha... it's a joke
