Droughts make flooding worse‼️ The healthier the soil is, the faster and better it can absorb water, such as for example rainfall. In this experiment Dr. Rob Thompson from the University of Reading shows just how long it takes water to soak into parched ground, illustrating why heavy rainfall after a drought can be dangerous and might lead to flashfloods. #climate #science #soil #nature Giuseppe Masanotti Valerio D.

I question this experiment, not necessarily the conclusion. Nothing is said about the “seal” between the rim of the cup and the ground. The thick, fluffy grass is preventing the cup from making any kind of seal with the ground, whereas the baked, parched grass does. A better experiment would take this factor out of the equation.
I think you need to remove the grass to get a more accurate result.
Hi folks, creation of bubbles means air is going in easily in first two glasses offcourse glases will have gaps with ground when on uneven grass creating space for water to drain under pressure when air goes in while the one on level ground is prefectly level even if little water gets absorbed it will create suction pressure which will not allow water to be absorbed further …,
This is a terrible video, the air bubbles give away there is no seal on the wet grass and less seal on the normal grass but after heatwave, there is somewhat of a seal.
Eine Erkenntnis, der die Landwirte schon viele Jahre folgen. Regnet es längere Zeit nicht oder ist/war es "extrem" warm und es wird Regen angekündigt, werden die Feld bewässert. So wird der Boden auf die Aufnahme von Regenwasser vorbereitet. Es kann somit verhindert werden, oder zumindest vermindert, dass das Regenwasser die Ernte weg spült. Wird der Boden nicht vorher bewässert, nimmt dieser das Regenwasser nicht auf und spült Pfanzen und Samen davon. Aber auch im eigenen Garten macht es Sinn. Kann somit auch der eigene Grund und Boden dadurch geschützt werden. Gerade unter Hecken und Sträucher sollte man "Vorwässern" um den Boden zur Aufname vom Regenwasser vorzubereiten.
Not sure why this is an ‘experiment’? The video is embarrassing! There is no context. Soil absorption, droughts and floods have been studied since the beginning of time. It is common knowledge, especially amongst conservation and farming all around the world with different climates, seasons, soil history, vegetation, and ground cover. It’s not new science and this video undermines all the hard work and dedication of real time experiments with real results.

With very dry soil you can Always use any machine to open the top-soil and dump slurry even end of winter when slurry is allowed on the field from 15th of February Most of food for our record levels of cattle is NOT produced on the farmers own fields BUT arrives in Rotterdam or Delfzijl harbor making soils quality a lower priority Why should UK be different ?
If your experiment is true (which is actually not indicative of absorption) then hortons equation becomes trash😀
If cracks in soil due to Heavy sun ☀ light , water will go inside the soil. Type of soil also matters , but if grass is there above is true. GRASS hold soil togather

5moIs the soil absorbing or is there more space to leave the cup and flood, because of the higher volumes grass keeping it higher from te ground? Also indicated with the airbubbles?
