- searine 6y ago>Wasn't the dust bowl caused by topsoil degradation? No. It was caused by extensive deep tillage as method of pest control. We have better tools and methods now.
- sp332 6y agoIt was caused by lack of cover plants. Farms are using cover crops like ryegrass more because it helps keep water in the soil better.
- Edman274 6y ago"These topsoil crisis stories have been running ever since that time that topsoil crisis killed thousands and caused widespread food insecurity. Utter hogwash. Well, it would be hogwash if any of the hogs had anything to eat."
- maxerickson 6y agoThe chemical fertilizer revolution happened in the 1950s. (which didn't disconnect productivity from soil condition, but it loosened the relationship)
- CapitalistCartr 6y agoThat is a different issue, a serious one. The claimed problem here is that farming relies on topsoil, which is not correct. Our factory farming doesn't rely on topsoil nutrients to feed the crops. Our current farming methods leave a lot to be desired.
