As I was reading this report about erosion, I thought to myself that this information was absolutely irrelevant to what I’m doing as the editor of The Planet Fixer Magazine. They were talking about the corn belt states, about the fact that they were losing ground which means a lot of erosion but nothing specific that I could use as a solution for the Planet Earth. Then suddenly at the end of the report, the conclusion:
The most highly effective practice is to plant strip of grass or trees within or along the edge of the crop fields
Bottom line is this: what ever is the country you are living in, if you want to protect your land from erosion, you will need to have buffers i.e. strips of grass or trees within the edge of the crop fields.This is the key, this is the secret, this is…your simple solution! By the way, I like the contradictions! On one side this is the corn belt where in the US they use the biggest tractors, chemicals, machines, pesticides and everything that is a no-no in my book. Nevertheless, they came up with super simple solutions that everybody can use!
- gullies are channels that reappears rapidly after a rain (and disappears with the sun)
- they are located where farmers have tilled and planted over natural depressions in the land
- they form pipelines that swiftly carry away the water the earth cannot absorb…and all the bad stuff with it
- and believe me…there is a lot of bad stuff in it!
- reduce soil erosion
- reduce polluted runoff
- reduce gully erosion
- simplest but most highly effective practice is to plant strips of grass or trees within or along the edges of crop fields. Grass strips are called filter strips because they filter out sediment and pollutants running off the edge of the field
- strips of grass or trees planted next to a stream are called riparian buffers. Riparian buffers are a last line of defense for filtering runoff water just before it enters a stream or ditch
- contour strips are planted as the name implies, along the contours of a sloping field. Contour strips slow and diminished runoff and filter mud and pollutants out of water as it flows across a field.
- vegetative barriers are very narrow strips of stiff stemmed vegetation planted across a sloping field to slow the water running down the slope, allowing mud and other pollutants to settle out
These simple practices can be highly effective. A review of published studies found that buffers trapped:
- 41 to 100 percent of the sediment
- 9 to 100 percent of the runoff water
- 27 to 96 percent of the phosphorus
- 7 to 100 percent of the nitrate
Two different arrangements are being tested. One converts 10 percent of the cropland into grass strips located at the bottoms of sloping fields. The second converts puts 10 percent into contour grass strips.

Watch carefully this video. It is very interesting but most of it is about…exposing the situation and how bad it is. Solutions will flash between your eyes just for a few seconds!
