StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

you're not taking more from the land than you are putting back into it, which right now we are doing.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

And when I say taking more, putting back, what are these things that we're taking and putting?

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

It's the nutrient inputs.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

It's the topsoil loss.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

It's the organic matter that you're taking.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

Because if you think about a garden, let's say you grow a plot of corn.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

that corn, when you harvest it out, you're taking mass from the system.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

You're taking it out.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

And yeah, some of that is being generated by photosynthesis and carbon that's being sequestered from the air.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

From the CO2 in the air.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

From the CO2 in the air, yeah.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

But what people will do these days, or stuff that we'll do in our backyard or we'll promote, is regenerative practices where you are adding back as much as you are.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

And yeah, maybe you are leaving something

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

for a crop called a cover crop, which you're basically just growing to generate biomass that you will cut and leave in place.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

Leave in place.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

Yes.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

Yes, of course.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

Yeah, yeah, exactly.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

Yeah, I mean, I think corn's an interesting one because corn is one of the crops, of course, that we've modified, right?

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

So most of the corn that you're seeing like in those fields is like a single ear hybrid corn variety that is only going to produce one per stock.
