Environmental Nonfiction: Lawns for Watershed and Climate Restoration

Grass lawns are not what they seem.  The green turfs of our residential neighborhoods are shamed for polluting our waterways and requiring lots of water. Troubles come instead from our application of fertilizers (chemical or organic), pesticides and herbicides.

By stopping the chemicals from above and letting the diverse ecosystems organize beneath, networks of fungi, bacteria and soil animals can thrive on the liquid carbon pushed out by grass. Nothing sequesters CO2 out of the atmosphere better than grass.

Here are four articles on the importance of turf grass in symbiosis with life of the rhizosphere below. Discover a place less understood than the ocean. When we manage intelligently in concert with nature, we can have green lawns, clean water, and cleaner sky.

Why Modifying Your Lawn Care Practices Will Do More to Abate Climate Change than Changing Your Car for a Hybrid

In the efforts to slow the ravages wrought by Climate Change, the hare may have beaten the hybrid car while munching on grass.  The real winners are non-fertilized green lawns and permaculture. The hare was just stimulating the plants to capture more carbon.

The bad news is that carbon in the atmosphere has risen in hockey-stick fashion. The incontrovertible truth is that 400 parts per million is 0.04% of greenhouse gasses. Most of the greenhouse gas preventing heat energy from escaping the planet is water vapor (95%).

Much as I like to deploy a sling psychrometer, observing and recording water vapor is challenging.  Besides, Charles David Keeling coming down from Mauna Loa (13,679 ft) with a hockey-stick scribed into the atmospheric CO2 graph is the stuff of legends.

Look not to melting ice in Greenland; look to your yard and neighborhood.  The green parts can do a lot to reverse climate change, to restore the more favorable environmental conditions of yesteryear. Given the super-sized effects of water vapor in the climate change debacle, how you treat your bit of grass turf is not insignificant. Click here for the article and to comment.

Fighting Climate Change with Grass & Clearer Skies Without the Purple Haze

The death of soil organisms and the loss of soil began with Article 106 of the Treaty of Versailles where the Haber-Bosch process of fixing nitrogen was given to American industries. This action was followed by the Dust Bowl and haze (“don’t know if it’s day or night”).  When left to its own devices lawn grass restores life to soil and creates the conditions conducive for earthworms to become “ecological engineers.” To fight sea level rise, Boston’s Mayor has called for the creation of new open spaces to maximize the green along urban waterfronts.

The Greens of Greenland Tell Why an Unfertilized Lawn is a Healthier Lawn Fighting Climate Change

Grow grass the way the Eric the Red did, and our waterways will benefit from less nutrient pollution, less blooming algae, and less natural gas burning to fix fertilizers.  When sixteen striped bass and a horseshoe crab were found dead on the shores of Little Pond on the south shore of Falmouth, lawn care in Massachusetts was forever changed, despite the fertilizer industry’s best science.  We’re not so different from those living long ago.

Let Green Water Cycle and Rivers Flow All Summer

Walking on grass stimulates photosynthesis. Plant cells send signals out over the mycorrhizae fungi network to distant bacteria that specialize in specific nutrients and minerals, such as fixed nitrogen.  Needed chemicals are sent over the microbial bridge back to plant cells.  Beneath the turf is the world’s largest organism, mycorrhizae fungi (unless your lawn is smaller than a blue whale).  Thanks to the Green Water Cycle when a square yard of soil is created by lawns, it results in adding a watering can (4.4 gallons) of water to the watershed.Click here for article and to comment.

ACTION: ORI’s Lawn for Watershed and Climate Restoration Challenge.

For a better future, the Ocean River Institute is going town by town, often in concert with Conservation Commissions, asking residents to pledge not to use quick-release fertilizer or spread chemicals on established lawns.  One-half pound per thousand square feet of lawn of 100% slow (controlled) release fertilizer is an option.

With more than 2,000 square miles of lawns in Massachusetts, we have the capacity to draw down 1.4 billion tons of carbon dioxide a year! Healthy lawns with deep soils (and active worms) can hold nine inches of rain to better protect homes from extreme weather events.  Wildlife will benefit from your participation in responsible stewardship.

Save the rhizosphere, a world less understood than the ocean!

Take up the Challenge

Pledge to act for healthy natural lawns.

Please comment why this action is important to you.


Invite others to save money on lawn care while capturing more carbon than recently planted trees.

(Often new trees are planted in poor soil and do not do well. Tree planting is not a simple solution. Science 08 May 2020)
Grasses are the best at soil building.
