Our lawns are about as unnatural an ecosystem as you're ever going to find. And by "unnatural," I mean you're just not going to find anything similar anywhere in nature.
Tell me where you're going to find several thousand square feet of Kentucky Bluegrass, neatly contained with sharp edges, kept at a length of 2-3 inches at all times, with no other vegetation allowed to penetrate the borders. Short answer: No where! Not in the woods, not in the rain forest, not in the desert, not in the tropics, not even on the prairie. Oh sure, there are pastures, where animals graze on grass, but there's nothing quite like a lawn anywhere outside our yards. It's entirely a man-made construct.
Lawns as we know them-- closely-cut areas of grass-- first emerged in 17th century England, where they were a status symbol of the aristrocracy. The nobility could show off that they could afford land that contained neither buildings nor food. The lawn was born as a recreational area, which is what remains today. Sort of a shag carpeting for outdoor living.
But no matter how you slice it, it ain't natural. Now don't get me wrong, I enjoy having a lush green lawn as much as the next All-American homeowner, but the standards we have set for our lawns have become nearly unsustainable. Anything less than a uniform blanket of perfectly green grass blades is seen as an ugly failure.
And that's why we've become so reliant on chemicals. If it's not brilliantly green from April until November? Failure. If clover appears? Failure. If success isn't instant? Failure. But those chemical fertilizers, are actually killing your yard's plant life because those chemicals are killing the microorganisms and fungi and bugs in your soil. Those critters are vital to a healthy ecosystem. Our planet thrived because of those critters long before chemical fertilizers arrived on the scene.
Not putting those chemicals on your lawn this year would be the first step toward restoring life to your soil.
But here's the thing: Just stopping the chemicals won't necessarily give you society's version of a perfect lawn. Why? Because lawns require a lot of nutrients, and they take a lot of abuse from foot traffic and pets and mother nature (winters, droughts, etc). Those nasty chemical fertilizers are one option to give your lawn the nutrients it needs, but as I said, the chemicals actually do more damage than good. They weaken the roots, they compact the soil, they cause thatch, they cause your lawn to become chemically dependent, they pollute the environment and can make you and your pets sick.
So while getting rid of the chemicals will slowly allow those vital microorganisms to return to your soil, there probably will never be enough of them naturally-occurring in your soil to give you that "wow" lawn.
So what do we do at Good Sweet Earth to make our lawn look great, without adding chemicals to it? We apply Worm Tea as an organic microbial soil drench-- Worm Tea has billions of those beneficial microorganisms and fungi living and breathing in one teaspoonful. Imagine what regularly applying Worm Tea to your yard could do for your soil! It could increase the amount of those wonderful microorganisms a thousandfold, or more, in just one season of regular applications!
And why is that important? Because those microorganisms break down organic matter in lawn-- clippings, leaves, worm castings, compost-- and release nutrients into your soil for your lawn to soak up. Worm Tea is like delivering billions of nutrient factories straight to your lawn.
So to reiterate: those microorganisms will always exist in a chemical-free lawn, but there probably won't ever be enough to sustain a truly healthy lawn all year. To get that healthy lawn, you need healthy soil, and to get soil healthy and nutrient-rich enough to sustain a beautiful lawn, you need to infuse it with more microorganisms! Worm Tea does it.
Contact us if you're interested in infusing your soil with billions of those wonderful nutrient factories this year, or read more about what it can do for your lawn.
As we look out at the snow-covered fields of Zeeland Township, MI, on this cold February morning, it’s hard to imagine any living critters in the soil surviving the frozen west Michigan winter.
But somehow they do! And come spring, the microbes, worms, beetles and fungi will erupt with new activity, helping to produce new life on our farms and in our yards.
But how cold is too cold for the survival of soil life? Can microbes live in the Antarctic, where air temperatures regularly linger around -50 degrees Fahrenheit? The answer is– surprisingly– yes!
From the Soil Science Society of America:
Soils located in polar regions are unique to those found elsewhere, as they contain permafrost. Permafrost is a thick subsurface layer of soil that is frozen year round. In Antarctica, during the coldest parts of the year, the entire soil system is frozen solid. Because of this, the soil is actually very dry, like in deserts! If this is true, wouldn’t it be impossible for living creatures to survive there? Antarctica surely looks like a lifeless, barren area…
Amazingly, there is life in Antarctic soils. Even in these extreme environments, scientists have been able to find soil microorganisms alive and thriving.
What scientists have found is that these tiny organisms are able to survive by living in microscopic films of water that stick to soil particles (adherence). The bond energy between water molecules and soil particles is so great that it prevents the thin layer of water from freezing, even at extremely low temperatures. Microbes live in this unfrozen water, which allows them to stay alive even during the long deep freeze of winter.
These microbes aren’t just surviving, either. During the winter, they are still consuming organic matter, “exhaling” carbon dioxide (CO2) and maintaining their populations. They are actually alive, not even hibernating!
You may wonder why scientists are willing to spend their time researching soil microbiology in such remote areas. Studying organisms in extreme and inhospitable environments like the Arctic and Antarctic allows scientists to make inferences about life on other planets. This type of research is also important for understanding how cold ecosystems function now, and how that might change in response to global climate change. Scientists are already starting to observe increased microbial activity in the polar regions. As temperatures rise, microorganisms are predicted to consume more soil organic matter, which could lead to the release of even more CO2 (a greenhouse gas) into the atmosphere.
Most of us don’t live in Antarctica, but in the northern parts of the hemisphere, it’s pretty cold in February. If you think you’ve got it bad, try to be inspired by the mighty polar microbes. They are some pretty tough organisms, and because of this, they can teach us very much.
At Good Sweet Earth, in order to more effectively treat lawns and gardens naturally and organically, we believe it’s important to fully understand soil and all of the life found within– even if that soil is found at the South Pole! That’s why we are members of organizations like the Soil Science Society of America. If you would like to put our knowledge and expertise to work in your yard this year, get in touch with us at Office@GoodSweetEarth.com. Or check out the products and services we offer.
There are millions upon millions of microbial inhabitants living in your yard’s soil, and a lion’s share of that population comprises bacteria and fungi. Those terms often illicit a negative reaction from us– they make us think of diseases and moldy food.
So what about the bacteria in our soil? Can it make us sick or cause diseases? Well, according to University of Purdue agronomy professor Ron Turco, the answer is most likely no.
“Most of the bacteria in soil can’t directly cause disease, as they don’t have the necessary biochemical abilities,” Dr. Turco recently said in a Q&A for the Soil Science Society of America. In fact, for soil to be healthy, it needs a lot of bacteria, and it needs a wide variety of bacteria (and fungi and nemotodes, etc.)
Dr Turco goes on to explain the diversity of microbial life found in healthy yards.
It’s estimated that the number of bacteria in soil is more than 100 million per gram of soil (dry weight equivalent); we also estimate there are 6,000 to 8,000 different types of bacteria per gram of soil. More surprising is the fact that the structure of the population can vary in the landscape over relatively short distances. While many bacteria are technically mobile, in soil they are more likely found attached to the soil surface, and most of their movement is controlled by the water flowing through soil pores.
Soil bacteria live in small clumps called micro-colonies that are attached to the soil surface. These micro-colonies tend to be associated with small soil aggregates, and the combination offers a form of protection from drying and predators (primarily protozoa). It also enhances the opportunity for genetic exchange.
So what does that bacteria actually contribute to the soil? Why does healthy soil need all this life? Dr Turco explains that too.
Soil microorganisms are responsible for breaking down plant residues and other carbon (C) inputs [fertilizers] and converting nitrogen (N) within the N-cycle. Because of their soil surface attachment strategy, their actions are also a fundamental part of the soil formation process.
In terms of activity and what soil bacteria are doing most of the time, we find that they are often “resting.” That’s because the large, bacterial population uses up the available nutrients quickly and then spends most of its time waiting for new food to arrive: residue inputs, fertilizers, waste materials, etc.
Ambient water and temperature conditions also have a major impact on the actions of the bacteria; they are the most negatively affected by low water availability and high temperatures. In general, the ideal conditions for plant growth are also the ideal conditions for microbial activity.
And the diversity? Why do we need lots of different kinds of bacteria?
The critical point is that the soil doesn’t contain just one type of bacteria or one set of abilities (enzymes). It’s also not full of pathogens, nor are all the bacteria in soil active all the time. Instead, soil activity changes with fluxes in moisture, temperature, and substrate input. In order to respond to an ever-changing array of inputs, the soil biology is biochemically (enzymatically) diverse in its ability to utilize foods and electron acceptors. This diversity gives soil its resilience.
It’s critical for your soil to have a variety of microbes living in it. A strong microorganism population also attracts macroorganisms– things like beetles, earthworms, centipedes, etc– which benefit your soil (and plants) as well.
So if you’re looking to give your soil a microbial boost– whether for your lawn or garden– Good Sweet Earth Worm Tea is a great place to start. Our Worm Tea, applied as a microbial drench or foliar spray, can introduce a variety of beneficial microbes to your lawn or garden. We brew our Worm Tea with a blend of collected rain water and steam distilled water, organic black strap molasses, and our own all-natural vermicompost. We sell it by the gallon for gardeners, and we can also apply a Worm Tea drench directly to your lawn several times a year to give your grass a boost. If you’re interested in giving your soil an infusion of life, get in touch with us about our Worm Tea at office@GoodSweetEarth.co or call us at 616-594-0693.
If you were to ask us to sum up in one sentence our vision for Good Sweet Earth, it would be the headline of this post– Healing the planet, one yard at a time.
We got started in the vermicompost business many years ago because we wanted to offer safer alternatives to chemical fertilizers and soil amendments. We expanded into lawn fertilization and garden services because we didn’t think there were enough organic alternatives available for people to care for their turf and home-grown fruits and veggies.
Chemicals are killing our soil. Corporate farming practices are killing our soil. Without healthy soil, our planet is doomed. So in order to save our soil, it’s our mission to encourage people to do three things: 1) Use less chemicals on their lawns and gardens, 2) Grow more of their own fruits and vegetables, instead of buying them from supermarkets, and 3) Support sustainable family farms.
To encourage the use of less harsh chemical fertilizers, we offer organic vermicompost and natural blends for your soil. And when a homeowner hires us to care for their lawn or garden, we teach them sustainable ways to treat pests and weeds– no harsh chemicals necessary!
To encourage people to grow more fruits and vegetables in their own gardens, we offer season-long crop consulting services— that’s a fancy way to say we’ve got a certified Master Gardener on staff who will walk you through your growing season, from selecting seeds and mapping out your garden to starting your seedlings and pest control to harvesting your bounty.
Finally, to support sustainable family farming, we encourage our customers to shop at local farmers markets. This is a great way to actually see the people who are growing your food, locally. No mealy, chemical-filled tomatoes grown in hot boxes in California, no soil-damaging farming practices utilized to grow corn. Just small family farms. We also donate a portion of our profits to organizations that support sustainable agriculture, like Farm Aid and the West Michigan Environmental Action Council. That means when you purchase products or services from us, you’re supporting west Michigan's natural resources and family farms.
At the end of the day, having a healthy yard is the biggest step many of us can take toward having a healthier planet. And by buying Good Sweet Earth products or services, the money you spend on organic yard care will have the potential to heal the planet well beyond the edge of your yard. Which then means we really can heal the planet, one yard at a time.

You know that smell in the air after a good rain? Or that smell that permeates the air when you dig into your garden’s soil every spring? Did you know there’s a scientific explanation for that smell?
The science behind that wonderful “fresh earth” aroma is geosmin.
Geosmin is an organic compound produced by a microorganism found in all soil, and it carries a distinct aroma and flavor. It’s what gives beets their earthy flavor. Sometimes if you drink water that’s been sitting out for a while, it develops a musty taste, and that, too, is caused by geosmin. Wine is known to pick up this flavor as well.
The flavor produced by geosmin isn’t always a pleasant one, but the aroma it gives off is quite pleasing to the senses. So where does that smell come from, and why do we get whiffs of it after a nice heavy precipitation? It’s pretty simple: When it rains, water fills the air pockets found in the soil, and the geosmin gets expelled into the air. Sometimes you’ll even get an earthy whiff of geosmin before it rains. How, you ask? Well, a low-pressure system can de-gas the soil and put those geosmin into the air before a drop of water even hits the ground, leading many of us to say things like “It’s gonna rain; I can smell it!”
