What a crap and unprepared presentation

Indígena

Informação interessante ❤

Som muito baixo, nós próximos vídeos tente melhorar

Muito bom

Muito bom

THank you! Great explanation and demonstration!!!

very clear, thanks

Muchas gracias por el video. Una muy buena expicación de la Terra Preta. Quizás debamos agregar: espera luego de hacer todo eso. Maybe 2000 años y tendrás la que ellos dejaron para nosotros. Thank you very much for the video. A very good explanation of Terra Preta. Maybe we should add: wait after doing all that. Maybe 2000 years and you will have the one they left for us. Muito obrigado pelo vídeo. Uma explicação muito boa sobre Terra Preta. Talvez devêssemos acrescentar: espere depois de fazer tudo isso. Talvez 2.000 anos e você terá aquele que eles deixaram para nós. Merci beaucoup pour la vidéo. Une très bonne explication de Terra Preta. Peut-être devrions-nous ajouter : attendez après avoir fait tout ça. Peut-être 2000 ans et vous aurez celui qu’ils nous ont laissé.

Como resultou o experimento do cultivo da batata en vertical? Os seus videos son moito interesantes e informativos. Eu aprendo moito con eles. Nao sei porque nao tenhen mais visitas. Saude e boa terra.

There isn't another video like this out there, thank you thank you thank you!

Oh…I recall a question I had regarding swales, if someone would be so kind as to advise me.. Will the land beneath a swale get washed away in a few years? Is there some sort of preventative measures to take, or not necessary… like, if there was a house at the top, would the weight of it combine with the water from the swales and wash away the slope from inside

Thank you ! What seemed daunting is now very clear to me …this was an excellent presentation. Sharing your skill and knowledge is wonderful. I’ve learned everything I needed to know for my plans and I can now look at my property with new eyes.

Thank you for making it easier to understand.

Merci!

Excelente aula. Obrigado por compartilhar!

Hi, although I have seen this video 6 years after it was made, it has helped me so much to finally understand the difference between the different concepts. I couldn’t get it when I read about it, but watching you do it with earth/clay has been ideal. Thanks so much

Thank you very much. Simplified to a great extent

Really great to learn from such an amazing and wise teacher! Thank you for sharing Stéphane, I look forward to taking the PDC at Anovafloresta!

a "key" point is called an inflection point in math: when a concave slope/function switches to a convex slope/function. the change in the slope at an inflection point is 0: it is no longer become steeper and not yet becoming flatter.

Seems to me term 'keyline' in this video is just some irrigation line. Keyline is simply a contour line that goes through the keypoint, i.e. a very specific contour line. Swales are trenches plus berms and can be located on any contour line, including the keyline.

Muito legal a forma que pensaram a estrutura para impermeabilização… Uma dúvida que tenho é, como fazemos se preciso interromper a fiada para uma colocar uma porta, por exemplo, corto o saco e faço um nó no final? E para não perder o que sobrou, faço outro nó, encho com terra e no fim outro nó? Difícil achar vídeos com esses detalhes

Thank you! You deepened my understanding of fungi.

Thank you SO much! This video completely cleared up the whole subject. I understood swales, but this made the keypoint and keylines equally understood. Your water and soil demonstration worked better for me than drawings. I subscribed to your channel, and I'm interested in watching whatever you make. Thank you again.

Hello! Great video. Can you explain the leveling tool? I've never seen that before and it looks very handy.

thank you a lot for your explanation !

Wow! For the first time I finally understand! Thanks!

thank you for explaining!

Thank you for the visual explanation.

Massa demais

Thanks much for the insightful demonstation.Made me think there might be something to adding berms in areas with high solar aspect on the up slope or higher on the downslope

Not clear enough regarding how to identify key points and how keylines work

Caracaa, ficou muito massa esses tijolos de adobe!!!

otimo vídeo

You keep repeating the water takes the shortest way down, but that is really misleading and not true. Water takes the way of the least resistance, or basically always where the angle down is bigger. But that is not always the shortest way. In fact this can be easily seen in practice with rivers, which are never the shortest path between the river source and the sea/ocean.

I had a lot of confusion with this too; this video helped quite a bit. Here's my two cents. Keyline/Keypoint - place where the valley (between ridges) changes from sharp slope to shallow slope (contour lines are farther apart). Keyline plow/keylines - subsoil ripping with a Keyline plow is started from just above Keypoint, down below contour on ridges (as video says, they 'hang' towards ridges). They are *off*-contour. Swale - trench with a berm on which is a food forest. They are level, *on*-contour. Similarities: both slow, spread and sink water. Keylines allegedly handles similar quantities of water (but more evenly spaced through subsoil of land). It should also reduce runoff in the same way (but I wonder about flooding situations: swales with good overflows should handle it better). Differences: Keylines are supposed to be a cheaper, less risky (eg. landslides from water), less permanent (which is good regarding Scales of Permanence - a Keylines system's concept), and more mechanization oriented (spacings should be very predictable). An emphasis is made of increasing decay of dead plant material due to presence of subsoiled air, water and biomass for increasing soil fertility. Some think keylines are for grazing, swales for trees (I've seen in places). Book says otherwise (Yeomans clearly mentions growing crops *and* pasture for grazing). This can also include orchards and pasture. Upon the whole, I think the only advantage I've seen for swales is that they might handle flooding better, and growing a food forest (bit more chaotic, diverse and less precisely spaced than orchards). Mark Shepard allegedly combines both systems (but I haven't found a really good video on that). Yeomans' system itself has dams and 'water channels' between them (swales? but no food forests are mentioned).

ala muito bom

Thank you so much! Less talk but great explanation. So clear and insightful! Thank you, sir

Thank you!

Thank you very much, that is great video to undeestand

Superb..best i've seen on the differences between these

Trabalho maravilhoso, parabéns

Very useful.

That was great Thank you

Very clear understandings!!!! Thank you!

A brilliantly simple way of explaining these 3 concepts delivered with one my favourite flavours of accent. Magnifique! 👌
