the soil of the prairies was probably produced over the period of time after the last ice-age. it isn't that thick. if it could accumulate at a rate of an inch a year it would be much deeper... Best guess is 500 years/inch to produce prairie topsoil which was approximately 10" thick when Europeans showed up.. There are two separate time spans here. One is the 13,000 years of prarie since the last ice age. One is 5000 years to build 10 inches of top soil. Either the process eventually maxed out at 10 inches of top soil or something very dramatic happened 5000 years ago to scour the top soil to very thin. Let's check back in meteorology - Nope, nothing that impressive that long ago. Conclusion, once the top soil reached 10 inches it maxed out and no longer grew. So the article is about a guy who can grow an inch a year. Excellent. Let's see how deep it is when it maxes out. Even better let's purchase the stuff by the truckload and move it elsewhere so it never does max out. |
