Earth Care Farm

Earthcare1

I’m taking a Master Composter Training course at University of Rhode Island this month and it’s been wonderful so far. I’m learning so much! The course is comprised of classroom lectures and fieldtrips. Unfortunately I had to miss the first class trip to Earth Care Farm in Charlestown, RI at the beginning of the month. I was so disappointed because I’ve wanted to visit the farm since first hearing about the operation nearly a year ago. I called up Earth Care founder Mike Merner and although he’s very busy at this time of year, he graciously agreed to show me around the farm on a separate occasion. So one morning before work last week, I headed down to South County. We couldn’t have picked a better day for my visit—it was the warmest day so far this season here in the northeast.

Earth Care is located at the end of a road aptly named Country Drive. The pavement ends at the farm’s gated entrance where an engraved wood sign reads, EARTH CARE FARM: WORKING IN HARMONY WITH NATURE. I continued down the dirt driveway and pulled up to the farmhouse. I grabbed my pen, notebook, and camera from my bag and stepped out of the car. The air smelled like earth. Signs pointing to the office directed me up onto the porch of the house. I peered in through the screen door and saw Mike sitting at the desk inside. I recognized him from a photo on the Earth Care website. He was on the phone but he waved me in and invited me to take a seat. He explained that he was on hold, trying to order a tractor part. When he hung up, I introduced myself and briefly explained that my No Trash Project was behind my interest in both small and large scale composting operations. I thanked him for taking the extra time to show me around the farm. He smiled and told me he was happy to do it.

We began the tour around to the side of the house where three small compost piles sit in front of a large fenced in garden. This is Mike’s personal compost. Mainly food scraps and yard debris. This three-pile setup is the same basic system implemented on a large scale at the farm. The first pile is the accumulating pile. A combination of nitrogenous (“green” stuff, like food scraps and grass clippings) and carbonaceous (“brown” stuff, like dried leaves) materials is added to this pile. The second pile is the composting pile. It was once the accumulating pile but when it’s turned over to the composting pile nothing more gets added. It must be aerated to assist in the decomposition of materials and to prevent the pile from becoming anaerobic . This can be done with a pitchfork or a shovel. The third pile is the finishing pile. Once the composting pile, it has been turned over to its final stage. This pile is rich, dark earth. Few materials remain identifiable, save some seashells, eggshells, and some woody materials, which take a very long time to break down. This is the pile to take from. The finished compost can now be used to enrich the garden soil and fertilize the crops.

Next we walked the rest of the way down the dirt drive to the large accumulating and composting windrows that lay beyond the garden. Mike told me that this year’s accumulating pile has quite a bit of woody material from all the trees that came down in the storms that moved through New England during the fall and winter months. Scattered across this pile were paper bags of yard debris. Earth Care also accepts animal manure, animal bedding, seaweed, paper, spent bark mulch, and food scraps. At one point in our conversation, I used the terms food waste and yard waste. Mike stopped me and put his hand on my shoulder and said ” We need to get away from using the word waste to describe compostable materials. It sends out the wrong vibrations.” Noted. I won’t forget that.

The compost piles at Earth Care reach thermophilic temperatures ranging between 104 and 160 degrees fahrenheit. Heat loving bacteria work quickly to consume materials. This energy generates heat within the compost pile and the high temperatures kill many harmful pathogens that can be found in animal manure. An equally large windrow lies beside the accumulating pile. This is the one of the composting piles. Payloader tractors are used to turn the piles bit by bit.

earthcareshells

Fairly large pieces of wood and molluscan seashells are visible in the composting pile. Wood contains a chemical compound called lignin. Second only to cellulose, lignin is one of the most abundant polymers on Earth. Because of its complex structure, lignin takes a very long time to break down. As do seashells. They’re comprised of calcium carbonate, which helps to raise the pH level of the finished compost. Earth Care accepts gurry and shells, two pre-consumer by-products of the fishing industry. Gurry is the word used to describe all the parts of fish that get discarded. This includes heads, tails, fins, and entrails.  An average of forty-five percent of all the organisms we pull out of the ocean for consumption becomes gurry. The rest is sold as food. Luckily, gurry and seashells make great soil conditioners and Earth Care is making great use of both. Delivery trucks dump the gurry into “containers” or troughs in the compost formed with the payloaders. Gurry is the one material that can be added to the composting pile and it serves to enhance the finished product. As the pile gets turned, the gurry is evenly distributed throughout.

While Mike and I stood talking about squid guts, a customer arrived to purchase some compost. An Earth Care employee named John loaded her pickup truck with a yard or so of mature black compost and Mike disappeared to the office to fetch her a receipt for payment. I took advantage of the pause in the lesson to take some pictures. When Mike returned we made our way up to the finished compost piles. The difference in the color and consistency of this windrow was vivid. Mike explained that this finished compost had been sifted through three-quarter inch screen to remove large debris that may interfere with plant growth. From what I understand, the screener is large machine that is towed into the farm. The compost tumbles through a large cylindrical drum screen and conveyor belts send the finished compost and the large debris in two different directions. The material that doesn’t fall through the screen (large debris) is added back into the accumulating pile. Mike picked up a handful of the dark finished material and held it out toward me. “There are more microorganisms in this handful of compost than there are people on this planet.” He said. Amazing.

Another customer arrived and with surprising agility and speed, John once again scooped up the black gold and deposited it into the bed of the man’s pickup truck. He was a landscaper who was about to plant some trees in a customer’s yard and was purchasing some compost “to give them a good fighting start.” A little help from some microbes could make a big difference.

Earth Care Farm was one of the first composting farms in the region to receive a USDA organic certification. But Mike decided to relinquish that title because he feels that the corruption within the department leads to regulations that have little to do with human and environmental health. And because the government owns the “O” word, Earth Care now uses words like holistic to describe their product. And phrases like, “working in harmony with nature.”

But as with anything, there is a good deal of trial and error in the composting business. I was telling Mike about the Nylon 4 in my compostable toothbrush and the claims that the synthetic will eventually break down in a backyard compost pile. He said he wanted to show me something and led me over to the pasture next to the finished compost. He started to explain that at one point they were accepting paper product from a manufacturer that among other things produced paper used to make hospital gowns and the sheets that are used to cover exam tables in doctors’ offices. Mike had been told by the company that all the products had been screened for any toxins and were deemed clean. But as the product broke down, Mike and his employees started to notice that something was being left behind. Fine synthetic fibers that had been woven into the paper were matting together and sticking to the screener as the compost was being sifted. “Here’s some.” Mike bent down and picked a bit of the material up out of the grass and dirt and handed it to me. “It’s polyester,” he said. “and when I called the company to ask about it they told me that there was nothing to worry about because the material wasn’t harmful to the environment and it would eventually break down. We spread the compost containing the stuff in this field many years ago and it’s still here.” The matted fibers are a nuisance and could potentially strangle seed sprouts and roots so Earth Care stopped accepting the paper product from that particular company.

My visit ended where it began, back in the garden. Mike mentioned that he was going to plant peas and beans later that day. It was time to get them in the ground. He invited me to join him and John for lunch. Unfortunately it was time for me to get back to Providence. Before we shook hands and parted, I asked him how long he’d been at this business. He told me that he started landscaping in 1972, bought the property we stood on in 1978, and then began the composting business in 1979. He explained that the idea to make and sell compost for agricultural and landscaping use was born out of a simple thought that came to him one day while he was digging in the garden, “Good health begins in the soil. If we have healthy soil we can grow healthy food to support healthy lives.”

    this is such a great write-up! i really enjoyed reading about the large-scale composting…it’s so different from small-scale (read: backyard) composting, which i’ve been doing for years. mike seems like such a great guy! lucky you to have gone out there + met him. :)

      Hi there! Yes, it was so valuable to see an operation like Earth Care’s. And Mike is a truly inspiring individual. Of course I’m always thinking about my own personal organic “waste” and more generally, residential organic waste. But it’s amazing to see a business that is turning industrial organic materials that would otherwise be discarded into a commodity.
