Gembloux Agro-Bio Tech (Université de Liège) est une faculté à la pointe du développement durable et de l'éco-innovation, reconnue internationalement depuis plus de 150 ans pour la qualité de son enseignement et l'excellence de ses recherches dans les domaines des sciences agronomiques ainsi que de l'ingénierie biologique.
Très intéressant, seriez vous intéressé de travailler avec nous ? Nous recevons des demandes d'études agronomique pour la création de jardins partagés assez souvent et votre expertise serait très utile !
This is golden!!! I'm am currently doing a master's thesis looking into moisture migration in grouting and tile adhesive in bathrooms walls. This video shows an excellent representation into the behavior between materials with different permeability and porosities. I can highly relate to the observations regarding the different layers. Thank you for this, and I will contact your University to ensure proper citations. Thanks from Norway!
I come back to this video every once in a while. It is of such great pedagogical value! It really helped me with the understanding of soil physics. Love that you included the example with aggregates, just goes to show how the soil properties are not only dependant on texture, but also structure. Thank you very much!
Did anyone take into account the compaction layers that were created between the glass plates? This study is actually a great representation of the erosion issues humans have had in the entire history of agriculture with waterlogging on top of compaction layers created by humans.
Bonjour, Sophie Delattre est diplômée du Master Bioingénieur orientation Chimie et bioindustries. Ce master se concentre sur les domaines de la transformation et de la valorisation industrielle de la matière vivante végétale, animale et microbienne.

Ces abrutis qui se prennent pour des génies et dégomment tout et une fois qu'ils ont bien fichu la merde... ils laissent faire la nature pour réparer leurs conneries !!
High IQ gardening theory crafting: Make a channel of sand underground under each row of vegetables and have the sand channel come up like a pipe in different spots. Pour water into these sand "pipes" and the water should flow under the plants and hydrate the surrounding dirt from the hydrostatic pressure. Significantly less evaporation, but more work to start off.
La preuve que les paysans ayants appris leurs métiers dans les écoles d'agricultures ont subit un formatage de cerveau pour faire vivre les lobbys puisque les néo-paysans qui n'ont pas appris l'agriculture s'en sortent mieux.
irrigation+rainfall = evaporation + transpiration + runoff + leaching Which one of these processes do Farmers really have control over during the growing season? If you have the ability to irrigate your sandy soils and water is cheap and plentiful, then you are fortunate and have some control on the left side of the equation. If you do not have irrigation, you must look at the factors on the right side of the equation to see what can be controlled or minimized to benefit your crop. Evaporation from the soil surface can be reduced with mulch or leaving crop residue on the soil surface. Transpiration is a function of the plant leaf surface area and the weather. Runoff is or should be minimal in sandy textured soils with high percolation rates. This leaves the leaching of water out of the root zone as the #1 controllable loss of moisture to your crop. Interrupting the downward movement of moisture in your soil by installing a "smart" barrier can greatly reduce the leaching of water and nutrients. SWRT subsurface membranes detain/retain up to 90% of irrigation or rainfall in the root zone for crop use by disrupting the gravitational movement of water in the soil while still allowing excess water to percolate and do not create anaerobic soil conditions.
De nouvelles techniques d'agricultures de bons sens sont nées des néo-paysans, plus humanistes, plus solidaires, plus soucieux de la santé, en opposition du productiviste conduisant des productions agricoles sous perfusions des multinationales. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QT7-YRn6PDI.html
Thank you for the video. I'm about to start a grafted finger lime garden, and didn't know what sort of soil to use. I think I'll go with sandy loam ("portulaca-mix") soil now instead of the 5-in-1 soil commonly found over here.
