Ryegrass Saves the Gulf of Mexico…well, not quite Yet!

An article in the recent issue of Grist spent a lot of ink reporting on the value of cover crops. They looked specifically at a small Indiana watershed (Tippecanoe) and recorded what happened to the water quality when cover crop adoption approached 100%. Perhaps more accurately, they recorded what DIDN’T happen…the nitrogen and phosphorus fertilizers stayed on the property and didn’t end up in the Gulf of Mexico.

In a short video, you can get the gist of what Grist had to say. Here’s that link.

But if you want to read the longer article, it’s worth it. Here’s that link, called Last Ditch Effort. Among those interviewed was Jamie Scott, an entrepreneurial grower in Indiana who has been instrumental for expanding the use of cover crop, particularly annual ryegrass, in the past 10 years.

Here’s a quote from the article, in terms of what they determined, in summary. After 13 years and a million dollars in state, nonprofit, and federal funding, the data show a clear decline in nitrogen and phosphorus flowing out of this watershed during the critical springtime thaw. These two nutrients fertilize crops, but when they wash into the water, they fertilize algae blooms and cause a host of problems. In other words, the chemicals we rely on to grow food often end up poisoning the planet and threatening the lives of many species on it, including ours.

Maybe you caught the editorial slant in the last sentence. Yes, Grist is an environmentalist magazine run by millenials who probably think they can right all the wrongs right away, if all the old folks would just quietly go away and die. But seriously, if a tree-hugging bunch of youngsters think cover cropping is going to save the planet, that’s good news…because cover crops can take care of a bunch of pollution problems, and that’s the truth.

Farmers, Environmental Organizations and the Feds Chorus the Benefits of Cover Crops

What doesn’t stay on farmlands can easily end up in nearby waterways and in the air we breathe.

Cover crops like annual ryegrass have become friends of the environment. Imagine living in an era when farmers and environmental advocates are standing side to side to champion cover crops.

  • Green Lands, Blue Waters is an effort to save the Great Lakes, major U.S. rivers and the Gulf of Mexico from pollutants that are killing our fresh water.
  • The Sierra Club has goals about how agriculture must be carried out in an environmentally sound manner. Among them, number 7 from the top is this: Agriculture must promote the use of cover crops and perennial crops to protect soils from erosion and protect water resources from nutrient runoff and leaching.
  • The federal Environmental Protection Agency says this: Growing cover crops is a beneficial practice to reduce nutrient and sediment losses from agricultural fields and improve water quality. Cover crops also increase soil health through enhancing soil organic matter content. 

Finally, until recently, crop insurance was in jeopardy when farmers decided to protect their land with annual ryegrass or another cover crop. But, because of the results of improved soil biology and crop productivity, because of pressure from the agricultural and environmental communities, the laws have now been changed to allow crop insurance on cover crops.

Show up with results…and you can move mountains…well, in this case, fix unhealthy soils and weak profits, while saving the purity of our fresh water and  air.
