I was struggling to understand the keyline concept, was getting stuck, and it happened every time I tried to understand, a big thanks to you, did understand well, very nice for even for a layman Sampath
Thanks for that explanation. It seems keyline spreads water. Whereas swales hold water back to fill the subsoil, and watertables. Im going to have a go at swales as it seems to suit my land. We have been informed a La Nina has formed and we should get some much needed rain. Not much rain in the past 5 years, especially the past two years. Even trees are dying.
Great demonstration, but aren't the keyline trenches supposed to be level? I am digging keyline trenches from a valley and it has been effective in pulling the water to the ridges.
Why does each keyline in a valley not slope downward towards each ridge? In other words, if you stand on the ridge of an A-frame roof and pour water on it, the water naturally flows down.
Why am I wrong in thinking that the off-contour lines should be skewed downward.in parallel? Wouldn't that make it easier for the water to naturally flow to the top of the ridge below? In other words, if the off-contour lines are horizontally parallel, it would seem, as in the demonstration, that the water would not always flow to the ridge. However, wouldn't gravity do more work for us if as the water flowed down and then to the right or left, the off-contour line was skewed downward, naturally forcing the water to continue a downward path to the ridge below?
The only thing I'm stuck on is why are the parallel lines above a contour necessarily going toward the ridge. Isn't it possible that they could be sloped slightly toward the valley rather than the ridge if we simply make parallel lines above a contour line?
Not sure if I understood completely what you said, but here it goes my attempt. ;-) If it leans toward the valley. The water will not spread in the direction of the outer ridge. In fact it would be a worse situation because more water would be directed to the valley, when the intention is precisely the opposite. Take it away from the valley. If parallel to the contour line, it will not be so effective. Because it will not favor a wider spread over the land. Remember the "key line" is a relatively shallow cut in the soil. It cannot contain a large amount of water. Although it can effectively distribute the water if a downstream condition is given. Cheers
downbntout - No. That´s a misunderstanding. In a topo map lines are on contour, or saying in another way at the same height. On the keyline system the lines lean from the valley to the ridge. Higher in the valley, lower in the ridge. Hope it help. Cheers
This is not a good explanation of Keyline pattern cultivation. The key Line by definition is an extension of the key point of the valley. The key point is that place where the topography changes from convex to concave. This is the place in the landscape where water will begin to slow in a landscape. One does not subsoil parallel to the Keyline. One crosses the keyline, higher in elevation from the valley to lower in elevation to the ridge. Water for Every Farm clearly shows keyline cultivation patterns as not being parallel to contour lines. The wrong application of subsoiling can actually dry up landscapes. Darren Doherty or Owen Hablutzel are to people to be paying attention to.
I have been reading about keyline for years and your video made it understandable, a picture really is worth a thousand words. thank you very much
+jim Same thing. This finally helped me understand. This was an excellent video.
To be honest it took me about 2 to 3 months trying to learn it and finally I knew it.

Thank You!! Finally I've grasp the keypoint/keyline concept!!!
This truly explains a lot of words plp have been using around me and put them all together in a very intuitive way. THANK you.
Always nice to have a small model landscape to use for these types of demonstrations. Thanks for this. Also, that baby is getting a great education...
Thank you for your brilliant and very useful work. A lot of love from Italy
Thank you for the first very clear explanation I have found so far of keyline! Greetings from Australia
Great video .... there's permaculture "experts" throwing around this term and never bothering to explain or or show how it works. Thank you.
Finally a simple video that made the concept easier to grasp.
Excellent explanation. Very much appreciated!
This is the first video explained me in simple terms with demonistration. Thank you!
More power to you and God Bless you and your family with great health and joy!
Awesome demonstration of Keylines in action.
Excellent demonstration and explanation. Thank you!!!
One of the best explanations, thanks for posting
Well put!! Simple yet effective explanation
Thanks to this I finally understood Keyline. Thank you.
Thank you very much for this great video. After reading many articles this video taught me.
Really simple when someone knows How to explain! 👏
Best keyline explanation I have come across... thank you
Thank you for this good explanation from Germany
Awesome demonstration
Salve! Parabéns pela explicação. Vi a camisa do Brasil ali em!
Very good instructor!
Thank you! Would you put a pond in the gullly/valley? What would plant towards the ridge?
Great explanation! Thanks.
Wonderfully helpful video for understanding key line thanks for the model.

Where are you located?
@@NASHTS Qld Australia.
@@peace4peaceful La Nina again this year by the looks of it..
Jazak Allah khair. Thank you for explaining.
Awesome the best explanation on youtube. Thanks!!!
Thank You, very easy to understand something I've heard about but not graspt before.
Great demonstration, but aren't the keyline trenches supposed to be level? I am digging keyline trenches from a valley and it has been effective in pulling the water to the ridges.
This was a great video and it helped me understand, thank you.
I now see the point of key line. I thought it was pointless in comparison to swales but they serve different purposes
Excellent model, good explanation. Very well done! I hope we will meet.

I think this is the first time I've seen a 3D model for keylines, I've only seen 2D models and my brain isn't good at adding the other dimension xAx
Excellent explanation.
Thank you, it really help me to understand it
nicely explained...ty
fantastic easy explanation thankyou
Great explanation! Thanks
very good! so didhatic
Thank you for the excellent explanation.
Many thanks brother Naeem.
is keyline the same as contour line?
Very helpful.
The only thing I'm stuck on is why are the parallel lines above a contour necessarily going toward the ridge. Isn't it possible that they could be sloped slightly toward the valley rather than the ridge if we simply make parallel lines above a contour line?

Thank you for sharing that great information
GREAT EXPLANATION IN UNDER FIVE MINUTES!
Crystal clear!
Thank you !
este video una buena referencia para evitar el empobrecimiento de la tierra
good explanation
Well done. Thank you Sir.
So a keyline is the same as a line on a topo map, then.

Frank Thrall - Please watch the video carefully. At 3:35 he clearly states "each one of this lines is actually downward..." ;-)
Cheers
thank you.
Thank you
The explanation is great but the camera made me dizzy.
Why is he moving so much?!
Very nice explanation. Camera guy sucks tho
You are like Mahatma Gandhi
very good! so didhatic
