Except in most of America! America places no value on education anymore D: it's terrible....I think all schools should have agricultural, finance/banking, and home (i.e. how houses function) classes. So many Americans don't understand very, very basic farming, or how investments work. Even worse, they don't even understand what asbestos is, how insulation works, or even how and why you need building permits

What you mean... Because as salt dissolves, it doesn't form molecules to "clog the pipes" of plants picking up moisture with their roots. That's actually a terrible way of explaining why plants dehydrate in the presence of higher than tolerable concentrations of salt. There's some truth to the water-tables rising for a lack of deep rooted vegetation, and that crop rotation tends to even fix the soil qualities disrupted by agricultural concentrations (using only one crop where it had been naturally diverse before farming)... There's a few reasonably good posts around here (like at the very top) to explain (partially) what's really going on at the chemistry level, but it's not just as simple as MinuteEarth people put out. Admittedly part of that is due to time-constraints on the video, and production requirements... However, if we just keep blaming agriculture for everything wrong in the environment WHAT THE HELL ARE YOU GOING TO EAT? There are seven billion (7,000,000,000) people in the world who want to eat at least once a day. It has to come from somewhere, so someone has to grow it.

Several people have written to complain about the inaccuracy of our depiction and explanation of soil-root water relations. Given that our MinuteEarth videos are, already, "longer than a minute" we sometimes are forced to represent processes in very simplified fashion. Explaining soil and plant water potential and resulting hydraulic flow completely and clearly and in plain language in a mere sentence or two is perhaps impossible, but at the very least was more challenging than we were able to do. What we tried to represent in the very simple drawing was the notion of a semi-permeable membrane that would allow water to pass into the plant, but not salt, and simultaneously that would illustrate that when salt levels were high in the soil solution this would act to slow the flow of water into the roots. Yes, a more detailed explanation would be that the water potential gradient is the driving force (and water always moves from high to low water potential); when soil water is fresh (not salty), water potential is more negative in the root than in the soil solution, and more negative yet at the leaf than root, and more negative in the air than the leaf- creating a gradient that “pulls” the water upwards through the soil-plant-air continuum. When solutes, like salt, are in high concentration in the soil water, that lowers the water potential in the soil water to levels that can be as low or lower than the water potential in the roots, slowing or stopping the influx of water.

Hi, informative video despite the inaccuracy in the osmosis part. I want to ask a question regarding the water level inside the soil. As stated in the video the salt in wet climate the salt get dissolved by the rain water and washed down to the underground water system. Would the amount of rain water added to the soil (which is clearly much more substantial than that in drought areas) push the underground water level up and with that all the salt within the soil? Why does this happen with crops in dry areas and not in wet climate, or in other words. why does the water in the ground of wet climate areas go away while that of dry areas accumulate, taking with them the salt in the soil? Also, by planting deep rooted plants as a solution for salted rising water level, would those plants be affected by the salt water? Thanks in advance for anyone who's kind enough to notice this comment and spare a few seconds to answer it

Normally plants use this to their advantage~! By having their inside with lots of molecules (electrolytes, etc.) the water goes into the plant. But when there's too much salt *outside* the plant... The water *leaves* the plant and goes outside. No water for plant. Plant sad.

Someone explain to me what those circles are at 2:31? Are they crops? Why are they so perfectly circular? I saw them on Google Earth and I was very confused by them. Wouldn't they wanna be square or rectangular instead of circular instead? There's that diamond shape between the circles that makes it look like a waste of space. Sorry, I just have had these questions for a while.

BosonCollider The reason most of them are packed in squares is because their land is adjacent to other plots they don't own. Then you have the potential for Demi circles. And then there's the matter of the trenching of the water lines now taking turns instead of being straight. It's just not worth the effort for the efficiency.

I have my doubts. From my understanding, the water table is lowering in significant agricultural areas, not rising. Irrigation (at least in the US) comes from groundwater, not rivers. The Ogallala Aquifer is the main source of water for a third of the agriculture in the US. It declined by about 10% from the 1950's to 2005. And given the "salt clogs plant pores" thing that so many people have pointed out, I think this is just some BS packaged to fool people who don't know enough about the subject.

Salt doesn't block roots. This is incorrect. Salt decreases the water potential in the soil. The water inside plants now have higher water potential than the water outside of it. This causes water to move from the roots to soil instead of from soil to the roots. Just stating the real facts about salty soil water.

Even though it might be expensive, we could destilate the water before putting it on the fields. So the salt in the ground gets dissolved and the water levels are rising without any salt added. Of course we could put stuff in the water which helps the plants to grow.

The salty water has a lower potential than the fresh water we use to water crops. The reason water goes up a plant in the first place is that water flows from high potential to low potential(from the roots, where a lot of water is, to the leaves, where not as much water resides). Solutes in the water lower the potential of the water in the ground, and this will decrease the flow rate. Eventually, the flow rate can be halted. If there are too many solutes, the water in the plant might have a higher potential than in the ground, so the water would flow from the plant back to the ground to decrease the solute concentration, dehydrating the plant. Just went over water potential in ap bio, does this sound correct?

@realmetatron

After some thought, I do agree with the others. The picture of salt clogging the roots is fundamentally incorrect: higher concentrations of salt outside the roots change the osmotic pressure and make water move out of the roots instead of into the roots.

The video already gave an example outside Australia! Extra info, there's another way that's been developed in South Eastern Australia to control this too, called "pasture cropping", where they leave the native grasses in place & plant crops straight into them after grazing them hard with sheep twice to stunt their growth. That method's been tested by the WA government & works on the sandy soils there & is now being taken up by permaculture farmers around the world (native grasses can have 1metre deep roots & because they're more plentiful than tree roots, there's a lot more soil carbon created & so far more water retention & so equal or more water table holding ability despite less depth of roots)

Do you realise that current farming practices are resulting in 10 tonnes of soil per year being removed from farmland for every person on earth? The mixing native plants in & using their roots to stop the water table rise has a side effect of securing soil & reducing that massive erosion that is destroying farmland & oceans. This is a MUCH better solution to the problem than using GMO to treat a symptom while ignoring the disease

I'm not really sure, other than I know that growing native perennial grasses achieves the same result, so if you eat grass fed meat instead of grain fed, that will certainly help encourage farmers to increase their use of this sort of system. Also eating the foods that are more suitable to grow in dry areas, such as sorghum instead of corn will also help (and some sorghum is a perennial with long roots & native to dry areas, so is capable of doing the stuff spoken of here. I'm sure there's a lot of similar plants too, look at the less standard plant foods available in your area & check their growing needs & eat if they look useful for the land :)

The simple solution is to bring agriculture indoors. This has numerous benefits, including the ability to remove pests and weeds without expensive/toxic chemicals, the ability to layer production, taking up less room, removing the influence of weather and seasons, and the ability to easily automate food production. The Japanese are making a lot of progress with this technique, with a single indoor farm there producing 12,000 heads of lettuce a DAY. Also interesting about this technique is that no sunlight is required--light is produced by LEDs. Adoption of more robust power sources like thorium and fusion reactors mean that crop production can easily become unlimited, making healthy fresh foods very inexpensive and readily available.

Salt molecules do not block 'narrow junctures of plants pluming' too much salt outside causes an inbalance of the salt concentrations which means water does not diffuse into the root hair cells via osmosis. Normally a plant actively transports Na+ ions into its root hair cell to lower the water potential meaning water diffuses into the plant from the soil, as water moves from an area of lower water potential to higher water potential. Had to be said

Short break: So less trees or plants with deep roots, bring groundwater to rise which includes salt. Would it make sence then to dug deep fountains for use, and let it vaporize in special pools. So this way the salt is trapped and the water is in the air and comes somewhere down as rainfall, which again is less salty ?

@lilaclizard4504
@lilaclizard4504 6 лет назад
I remember years ago seeing on the news & various shows how there were salt crusts developing in croplands in the area near where I live (South Eastern Australia) & destroying crops & raising serious issues as to the future of the farmland. It was worse in the drier areas, but as they lost cropland to this, it followed them & continued spreading. I never actually heard what happened to that salt issue until this video, I knew it appeared to have been halted, but never knew how until now. So I guess planting acacia trees & salt tolerant native grasses has fixed the problem (some species of acacia trees/bushes & native grasses in Australia can grow in even absolutely arid/desert areas, as long as they get an inch or so of rain every few years they survive)

I've only had a few courses in plant ecology and soil sciences but I'm pretty sure that salty soil causes dehydration in plants because it raises the water potential of the soil, making less water accessible to the roots, not because it gets stuck in the pores of plant roots.
