“Understanding a soil’s properties and how it functions at a specific location is critical for informing sustainable land management practices. However, current sources of soil information are not accurate enough to meet that goal,” explains Jonathan Maynard, a soil scientist at the University of Colorado at Boulder who works on LandPKS and led the soilID redesign. Jonathan continues, “the value of soilID is that, through measuring a few key soil properties at a site and then linking that soil information to existing soil maps, we can minimize the uncertainty associated with those maps by identifying the most likely soil type at a location.” When users can identify their soil type, it is like handing them a key they can use to unlock a treasure trove of information about their soil and allows them to gain a better understanding of how their land will respond to different types of management.
We sought to accomplish two main things with the new version of SoilID. The first was to make soil information easier for the user to interpret, through a redesign of the visual interface. The second was to provide users with additional sources of soil information to help inform decision making, including improved links to ecological site information and additional soil interpretation from SoilWeb. Recognizing recent, continuing improvements in digital soil mapping and the potential utility of those products, we now also provide a link to SoilGrids v2.0 which provides soil property predictions at a 250-meter spatial resolution.
In addition, this new version of SoilID also allows users to select their soil from the list of mapped soil types, or to enter the name of a soil that is not mapped in that area. This new feature provides valuable feedback to soil mappers that can be used to help improve future updates to existing soil maps. Identifying the soil type also allows users to access more detailed soil information that is not always possible to measure in the field, including many physical and chemical properties or ecological site information.
The visual redesign presented some challenges when it came to representing soil texture, one of the most important properties that influences how a soil functions. Soil texture is made up of 3 particle size classes (sand, silt, and clay), and the distribution of those 3 classes is typically represented in a pyramid, difficult to display in a linear way. Thus, when viewing soil texture profiles, it can be challenging to interpret the relative similarity of soil texture between the soil types mapped in an area.
We began the redesign process by surveying various soil scientists and other experts on different ways of displaying soil texture information. Through the survey, we were able to identify two types of users: those who wanted to see relative textures in a single legend, and those who wanted to know the individual texture classes.
“In the new version of soilID, we display soil texture on a linear gradient based on mean particle size diameter, which allows us to visualize the soil based on the relative difference in the amount of sand versus clay,” Jonathan explains. This then relates to the general differences in soil function, such as water holding capacity or general nutrient availability. For those who want to see the individual texture classes, we provide another legend, using the texture class abbreviations.
Ultimately, Jonathan says, “the idea behind soilID is to provide the most accurate soil information at a site and to make that information interpretable to the end user.” Download the most recent version of LandPKS today and let us know what you think!
“Taking the Guesswork out of Soil Identification”
Part two in a series of blog posts that tells the story of how Eco-Cycle and LandPKS came to collaborate. It also tells a bigger story: one about synergies between organic waste management and soil health. If you haven’t yet, read part 1 first.
After over a decade of managing Gem o’ the Field, an organic farm just north of Boulder, Colorado, Dan Matsch found himself at a crossroads. He had just turned forty. Though Gem o’ the Field did brisk business at the Boulder County Farmers Market and was making a modest profit, Dan still didn’t have the funds to hire the full-time management staff he desperately needed. So, in 2001, Dan planted his final season of crops. That same year, he joined Eco-Cycle, where he already served on the volunteer board of directors, as an employee.
When Dan joined Eco-Cycle, the company was focused on one big question: how to build zero-waste communities. They steered their attention specifically towards organic waste. Comprising about 30% of the total waste stream, organic waste includes food scraps and garden trimmings, and, if uncontaminated by other waste such as plastic, is entirely compostable. The directors of Eco-Cycle wanted to look into the possibilities of composting on local organic farms. It was a research project, and they asked Dan to take it over.
After over a decade of working as an organic farmer and building his own compost, Dan seemed predestined for the job. However, he quickly unearthed an inconvenient fact: the State of Colorado does not allow for organic waste to be brought to farms for composting. The project was a dead end, its premise against state regulations. For a couple of years, Dan put composting on the back burner to work on another new Eco-Cycle initiative: the CHaRM.
Welcome to CHaRM
In the same year that Dan joined the staff, Eco-Cycle opened its Center for Hard to Recycle Materials, or CHaRM, and they asked Dan to manage it. The first facility of its kind in the United States, CHaRM began by recycling select electronics. Today, CHaRM recycles all types of electronics, as well as hard-to-recycle plastics, packing materials, appliances, mattresses, and more. Thinking back on the intensity of those first years at Eco-Cycle, Dan says, “the reality was, I hardly had any time to think about compost, because I was the only employee at CHaRM!”
Composting and recycling in Boulder, Colorado, in the early 2000s looked very different than it does today. The City of Boulder had no curbside program for organic waste collection, except for yard-waste, until 2006. In 2004, Eco-Cycle launched Colorado’s first commercial food waste collection program. Because of the special kind of truck required for residential hauling, Eco-Cycle stuck with the commercial side of things, picking up organic waste from restaurants and grocery stores and hauling the waste to A1 Organics in Golden, Colorado.
Also around this time, Dan and his colleague were shown a compost tea brewer at a trade show. They bought it on the spot, and Dan started brewing compost tea at CHaRM. “By then, a bunch of people were excited about recycling their organics, so we let people come to CHaRM with their kitchen scraps,” Dan explains. At CHaRM, this waste was vermicomposted to brew a “tea” of beneficial soil microbes and soil nutrients, which could then be poured into a watering can or an irrigation system and easily distributed across cropland. It wasn’t the massive on-farm composting program with curbside pickup that Dan had once dreamt of implementing, and didn’t have the benefit of adding organic matter to the soil, but it was a quick and easy way to start creating a compost product at CHaRM.
Back to the Farmers Market
If there was a single message that Eco-Cycle sought to convey in the early 2000s, it was that zero-waste and composting went hand-in-hand. In 2004, Eco-Cycle launched their first zero-waste event at Dan’s old stomping grounds, the Boulder County Farmers Market. It gave Dan a strange feeling to go back to the farmers market, which he had just left three years ago, to present them with the idea. However, his familiarity with the market was an advantage when it came to organizing the event. “I promised them we would take care of everything,” Dan recalls.
Zero-waste events were a brand-new concept, and Dan and Eco-Cycle needed to define the parameters. There would be no trash cans, only recycling and compost bins. Food vendors would be required to use compostable food packaging. A1 organics had agreed to receive the compost from these events. Sometimes, a few of Eco-Cycle’s dedicated volunteers would act as goalies for the bins, making sure that people put the right types of waste in each. However, Dan found that the most critical factor was signage design. It was crucial that the bins had clear, appealing signage so that people could comply with the disposal rules.
Dan and others Eco-Cycle thought that, as long as they were present at the farmers market, they might as well sell a product. As BCFM only allowed vendors to sell what they’d produced themselves, Eco-Cycle began selling their compost tea. But as a former BCFM vendor, Dan wanted to make sure that the product he was selling actually worked, so he began conducting compost tea trials at CHaRM and on his old farm.
Dan’s experiments were not particularly scientific, but they did seem to indicate some benefits of applying compost tea. “For example, I had this big, empty greenhouse at the farm. Every year we would have an outbreak of grasshoppers inside the greenhouse. I planted some trays of basil in the greenhouse, half with and the other half without tea. But I had completely forgotten about the grasshopper outbreak! I showed up one day and immediately knew: oh no, the grasshoppers had hatched. The control basil was shotgun-riddled with holes. On the test side that had been treated with compost tea, there were only a couple of holes.” Dan’s interpretation was that the tea’s microbes seemed to build healthier soil, which grew healthier plants.
It became Dan’s passion to demonstrate to people that it’s possible to create high-value products like compost tea out of food waste.
A transformative moment for Dan was hearing John Wick of the Marin Carbon Project speak at a conference in 2012. Wick’s message of hope for climate change mitigation through what he called “carbon farming” gave Dan “a new sense of purpose. When I heard him make this connection between compost and climate change, bells went off.” From then on, educating people about the connection between soil health and climate change became Dan’s mission, and Eco-Cycle and CHaRM would provide him with the scaffolding for outreach and collaboration that would enable the next decade of his career.
This post is part one of a three-part series about the story of LandPKS’s partnership with Eco-Cycle. The series also tells a bigger story: one about synergies between organic waste management and soil health.
Like soil, life has layers. We go through phases and, more often than not, certain themes recur. Some collaborations only happen on the surface; others take root much deeper, connecting multiple layers of experience. This series of blog posts tell the story of how Eco-Cycle and LandPKS came to collaborate. It also tells a bigger story: one about synergies between organic farming, organic waste management and composting, and the health of soil. This first blog post tells the story of Dan Matsch, Manager at Eco-Cycle, and how he came to understand the fundamental connection between our two organizations.
“The farm was like Disneyland for me.”
Every summer when Dan Matsch was a little kid, his family would drive from Colorado to Iowa, where his uncles owned a farm. Dan loved it there: the animals, the tractors and equipment, and being outside. “The farm was like Disneyland for me,” he says. However, growing up just east of the Rocky Mountains near Denver, where summers are short and the climate is dry, farming didn’t have much appeal, and Dan wouldn’t be reintroduced to farming until he was in his twenties.
For college, Dan studied architecture at the University of Michigan, but his real education began after graduation. He stayed in Ann Arbor and rented a room in a house that was owned by one of the founders of Recycle Ann Arbor, a non-profit waste management agency. Through his housemate connections, Dan started working at Recycle Ann Arbor too, which began his career in the recycling business. Yet, an even more formative experience he had while living in that house was farming in the backyard.
“I was recycling for a job and gardening for fun.”
Reflecting on his first summer in that house, Dan says that the backyard “seemed completely wild to me. It was a jumble of trees and shrubs. I had no idea what was going on back there.” However, soon his housemates started bringing fresh fruit and vegetables in from the yard — “incredible stuff,” he remembers. “I can remember the first time my housemate came into the house and handed me a peach. I didn’t even know there was a peach tree out there. It tasted outrageous.”
In addition to the taste of the food, Dan loved the idea of providing for himself. There was an appeal to self-sufficiency, of growing something from start to finish. He sums up that period in his life this way: “I was recycling for a job and gardening for fun.”
A few years later, Dan enrolled in a program for agroecology at the University of California Santa Cruz. The program is built around a working farm, which the small cohort of under 30 students is responsible for keeping afloat. Looking back on the experience, Dan says, “It was fabulous. Immersive. You live there, you work there, you’re all in. I can’t imagine better preparation for farming on your own.”
Dan met his wife, Carol Conigliaro, in the program, and they planned to remain in California to farm after graduation. However, the plan changed when his sister married and Dan came back to Colorado for the wedding. His parents had purchased a new property in Boulder County. While visiting, he saw some organic farming going on in the neighborhood and thought to himself, “Good enough!” He told Carol that he thought it could work, and she was open to the idea. In 1989, they moved to Colorado to start a new farm on the family land.
Gem o’ the Field
“You couldn’t start more from scratch than we did, beginning with the soil, or lack thereof. It was very sandy and thin,” Dan says. Though he had ordered some lab tests of soil samples and talked to the neighbors about their land, it wasn’t adequate to really understand the variety of soil conditions on their farm, which they named Gem o’ the Field. Located on the Left Hand Creek floodplain, the land had been scoured by fast-moving water, which left rocks and rubble behind. As Dan dryly puts it, “it’s not exactly the Nile floodplain.”
In addition to the difficult soil, Dan recalls that there was no infrastructure to speak of: no irrigation system, no power, and no equipment. In spite of the significant challenges at the beginning, they made it work. With some help from his dad, Dan bought an old tractor. Dan learned how to weld, and they built a greenhouse for starting transplants.
Because the farm was at the base of the foothills, Dan and Carol could grow cool-season crops through the summer. The Boulder County Farmers’ Market was a good way to ease into the market, and theirs became the go-to stand for mixed greens. They bought an old milk truck to keep their produce fresh at the market, which gave them an extra competitive edge. After a couple of years, the farm was working, and Dan and Carol were making a modest income.
When it came to planning, however, Dan and Carol had different aspirations. While Dan was focused on improving infrastructure and expanding the farm, Carol wanted to pursue other activities in the off-season. Eventually Carol went back to school and got a degree in Chinese medicine and Dan continued to run the farm without her. “But you know, it eventually caught up with me,” he says.
“I had employees, and this new burden of accounting and payroll. I wasn’t realistic about the time that took. I would do it in evenings and in my spare time, but it became all-consuming. For at least nine to ten months of the year, I was on seven days a week, slowly burning myself out. I loved it, but I had to face the fact that my body was kind of breaking down.”
When Dan turned 40, he reevaluated. The farm was on marginal land and there was no clear possibility of expanding into better ground. He thought that, if he wanted to keep farming, he would have to start over somewhere else. “I didn’t feel like I was up for that,” he says. Dan stopped farming in 2001 and returned to his first line of work—the recycling business. He’s been working at Eco-Cycle ever since.
In 2013, a big flood swept across the Left Hand Creek floodplain. They had 18 inches of rain over the course of three days in September, usually one of the driest months. The flood washed away ten acres of topsoil. Dan says he will never forget walking through the property after the water subsided. He saw his soil profile for the first time in the eight-foot-deep arroyos: “The topsoil was sandy, but ok. Below it was two feet of rubble, then another six inches of topsoil, then another two feet of rubble, then another six inches of topsoil. That completely changed my perspective on the land, and I understood why I was having so much trouble.” Over three days, a flood revealed why ten years of farming had been so challenging.
“If I had had LandPKS at that time, I really doubt that I would have farmed there.”
LandPKS could have helped them in several ways, Dan explains. First of all, LandPKS could have helped them track management decisions and better understand what methods worked. Just trying to keep the soil moist required constant work, and Dan estimates that he spent a quarter of his time moving irrigation pipe. Though they paid a lot of attention to their soil, they didn’t have good tools for measuring it or for documenting their soil management decisions. Dan says that the LandPKS LandManagement module could have helped him keep better records and see some patterns that eluded him as a farmer.
The LandInfo module also could have been of use. “LandPKS offers immediate feedback, which would have been helpful to get a better sense of the whole property. The irony of it was, we were using the wrong part of our land,” Dan tells me. “Left Hand Creek bisected our property: the floodplain is on one side, and that’s where all of the development was. Across the creek, it’s a completely different ecosystem.”
There were a number of challenges associated with expanding across the creek, including the necessity of hiring more employees, and it took seven years before Dan was ready to do it. When he eventually did expand the farm to the other side of the property, he discovered the soil was a Valmont, much better soil for agriculture. “If we had had LandPKS, we would have learned exactly what that soil across the creek was from the start, and that could have completely changed what happened.”
For Dan, farming in Boulder County was bittersweet. “We had a good 13-year run. Our stuff was good. We poured our heart and soul into it and it showed. We had a really good reputation at the farmer’s market. I had a lot of pride in what we were able to accomplish under pretty tough conditions, but I wouldn’t do it again, and if I had had LandPKS at that time, I really doubt that I would have farmed there.”
Back to Recycling
Over the years, Dan and Carol learned a lot about soil. Since their sandy soil required a lot of added organic matter, Dan began making his own compost out of manure from a nearby goat dairy. Eco-Cycle, one of the oldest and largest non-profit recyclers in the United States, approached Dan when he stopped farming. They needed someone with composting expertise who could take on the challenges of organic waste management. The initial idea was to transport organic waste to local farms, where the composting would then happen on site. Did that work, I asked Dan? “No. But there are other possibilities, and I’ve spent the last 19 years trying to figure that out.”
