Why the global soil shortage threatens food, medicine and the climate

Come on, man!

Corn yields in the US are up 80% since 1990.

Irwin and Hubbs (2020) offer an interesting read on how these trend lines are affected by what year you choose to begin the estimation. In particular, one must be cautious when using short time periods because of the greater effects unusual individual years (e.g., drought of 2012) can have on that estimation.

If you look at the chart it would be 50%.

I remember the folks struggling on the home farm. The year after they retired and rented in out the yields began to go up. Look at the chart for the mid 50’s

Happy now, Karen?

Much MUCH more than a drop per second. The solar wind strips away the upper atmosphere every day the earth has lost a quarter of its water since formation. This why Mars is a desiccated hulk when clearly there was water all over it at one point the evidence is everywhere you look on Mars. Mars is smaller it lost it’s magnetic shield hundreds of millions of years ago and the sun stripped bare. The earth still has an active magnetic shield so it’s a slower process here plus we are four times larger in mass. In a few billion years we screwed today and in humanities span nope no worries mates. The average species on earth enjoys a lifespan of just over 2 million years before going extinct. Humans have been modern humans for 250,000 and sapiens for 1.5 million we have a blink in geological time left even if that’s 500,000 years it is a tiny blink in deep geological time.

An excellent method

For real?????

[metmom]

Now there is a dirt shortage. Is there anything democrats can’t screw up?

No.

said, "I call BS on this “soil shortage! All around our area farmland is being bought and thousands of acres of trees are being cut down...for solar panels!"

They create the soil shortage. Which is why the supervillin Gates is buying them up.

I'm looking into buying a small farm. Practically speaking they're a very bad investment. You can't make a profit on them if you go into it with a loan. When the old farmers retire and not passed on to their family the land is sold which is the main reason there is a "soil shortage"

I love that technique. Too bad it requires so much equipment. That makes it hard for small-to-midsize farms to make the switch.

I’m testing the idea of “living mulch” this year. Basically just short plants seeded alongside the bigger crop plants. We’ll see how it does.

With the heavy development all around Madison, Wis., those farms have been swallowed up completely. I was raised west of Madison-—and everything is expensive fancy homes & the ‘soil is covered with concrete & blacktop. Used to be all family dairy farms.

Keep in mind that farmers have NOT been allowed to spread their cow manure back ONTO the land like we sued to do.

Dairy farmers had to install EXPENSIVE slurry tanks & PAY to have that home made fertilizer shipped out of the state.

Many dairy farms switched to beef cattle over that one demand alone.

[ridesthemiles]

I have plenty of free horse manure for anyone who wants to transport it themselves.

What do people expect when they fill/pave over prime farm land with parking lots, shopping centers, business parks, and housing developments?

[dkGba]

Absolutely but climate change loonies don’t want to acknowledge that. No soil- ie farmland- no food!! Their answer- fake food made in factories. Absolute lack of logic on their part is truly mind boggling!

You're right prevailing belief the magnetic field slipped away over time. That is likely partly correct as the core cools the magnetic field would weaken. I believe the trigger happened during one of the Heinrich events which effects our solar system not just the earth. Heinrich event is a 6000 year cycle which every other cycle is far greater. The last Heinrich event dubbed the Noah event likely associated with the Burckle Crater that hit the Indian ocean. In short I believe the Heinrich events are massive solar flares.

As for the water. The vast majority of the earths water is in the crust and mantel. Estimated 10X that of our oceans. It should be expected similar with other planets and stars.

The roller is low tech. Just a drum with blades and some people make it so you can put water in the drum like a lawn roller.

Foot on board that has piece of steel on the bottom side.

Different one

The edge on the hunk of steel does the crimping

The no-till seeder is the high tech implement but planting can be done by hand for most veggies. Some people broadcast seed and then run over it with the roller again to jostle the seed so it falls down between stems/leaves and hopefully makes it to the ground.

A cover crop has to be terminated. Depending on where you are, many will winter kill. Some things can be mowed and they won't come back so with those, you could mow, rake it off to the side, plant and then bring it back in as a mulch.

[Steve Van Doorn]

Remember there are two types of Climate change loonies. The scammers and those that believe the scammers.

Which is why the scammers don't mind buying beach front property.

[Steve Van Doorn]

A cover crop has to be terminated. There is two ways to kill the cover crop:
There are the dedicated "no-till" farmers and those that believe in healthy soil. The latter doesn't mind using roundup to kill to terminate the cover crop.

Here’s another interesting factoid (I’m sure you must know): when looking at a heat map of the Earth from space, what’s the difference between a city and a desert?

NONE.
