The soil health practices employed by SoilKeepers are designed to increase carbon and nitrogen storage.
This diagram shows the movement of carbon between land, atmosphere, soil and oceans in billions of tons of carbon per year. Yellow numbers are natural fluxes, red are human contributions in billions of tons of carbon per year. White numbers indicate stored carbon.
The largest sink we have to store more carbon is our soil. Through soil keeping we reduce the supply of carbon from land use change and increase the demand side of soil carbon uptake.
Our clients ask how much can we help? Based on one application of .5 inches of quality compost, and not including possible increase attributable to increased soil organism health, according to Ryals et al., 2013, an additional ~ 700 lbs. of soil carbon per acre per year is added to the soil.
If one asks, how much would a one time application on most of the Earth’s land surface help absorb the 4 billion tons of human produced atmospheric carbon? Well, there are 36 billion acres of land on Planet Earth. A one time application of 1/2 inch of compost on 12 billion of these acres would completely absorb our yearly human production.
So, we provide to each of our clients on an occasional basis what we presently call Planet Earth Thank You’s – our own certificate of stewardship for helping improve the health of our carbon and nitrogen cycles.
