Like Earth, the interior of Mars has undergone a process known as differentiation. This is where a planet, due to its physical or chemical compositions, forms into layers, with denser materials concentrated at the center and less dense materials closer to the surface. In Mars case, this translates to a core that is between 1700 and 1850 km (1050 1150 mi) in radius and composed primarily of iron, nickel and sulfur.
This core is surrounded by a silicate mantle that clearly experienced tectonic and volcanic activity in the past, but which now appears to be dormant. Besides silicon and oxygen, the most abundant elements in the Martian crust are iron, magnesium, aluminum, calcium, and potassium. Oxidation of the iron dust is what gives the surface its reddish hue.
...
The Martian core, by contrast, is largely solid and does not move. As a result, the planet lacks a magnetic field and is constantly bombarded by radiation. It is speculated that this is one of the reasons why the surface has become lifeless in recent eons, despite the evidence of liquid, flowing water at one time.

Exactly and soil is just one tiny link in a whole ecosystem. The primary problem is how to create a planet enveloping magnetic field to help protect your gains.
Discounting that I think I would start by putting an inflatable dome over a crater in a low lying area just to see what kind of temperature can be attained by normal solar heating and if any moisture migrates out of the soil. You would have to heat the dome at night and condition the soil but that’s the way I would start.
I did find an article about growing things in lunar and martian soil analogs. http://www.spacesafetymagazine.com/spaceflight/space-food/wageningen-ur-study-possibility-plant-growth-mars/
To me its all interesting to ponder but I have unlimited imaginary funds.
Moon dirt will kill you since its essentially just microscopic shards of glass.
Now you have done it.
I love Mars bars.
About once every two years or so, I run across them in a store, and buy enough of them to make me feel like a pig.
Ordered them online once, but that was insanely expensive.
Read the reasoning behind why they aren’t regularly marketed in the US once, but forgot what it was.
It would appear the core is rather large as compared to the caramel mantle and the dark chocolate crust. My detailed research has revealed that much like the 3 Musketeers and Milky Way, Mars' core is made primarily of nougat.
You're giving libs too much credit.
Good to see you posting, johnny
Red Velvet Cake ???? Damn ...I’m going !!

One problem about the ol’ Red Planet: terrible ass wind storms. Wind speeds of up to 400 mph are common and they can last weeks at a time. All that silica, iron, rock and Lord knows what else flying around... forget it. Thanks for the link. I have an imaginary space ship but dang it, I need a new ion- drive engine and wouldn’t you know they cost a bundle. Could you spare a few million? :-)
LOL! But ‘’Diamonds Are A Girls Best Friend’’. Aren’t they? (thanks for the link.)
Are you not?
Living and breathing soil is one thing and non-living regolith is something more than just quite different.
Chocolate, nougat, caramel.........
One also has to calculate the air pressure as well. While they may be terrific winds, they hardly exert any force at all, barely enough to lift the dust.
In the same vein, a dainty 5mph wind on Venus would knock you flat.
Your feckless ambivalence over this subject is extremely disturbing.......
Ima gonna start to cry.......
Liberal’s good intentions?
