The source is the horse, of course

Colorado companies blaze a trail by taking what is left behind

Horse manure gets a bad rap. Not only because it is, well… manure… but also due to a reputation for weed seeds when used on pastures, fields, gardens, etc. A pair of related Colorado companies — Colorado Manure Hauling (CMH) and Richer Lands Compost — is looking to change that perception by becoming one of the only, if not THE only, business combination in the country to perform the hauling and composting of equine waste to create a high-quality compost for commercial and residential use. While other businesses compost horse manure, they blend it with other organics. It is believed that CMH and Richer Lands Compost are the only ones to use equine waste as a single-source for their final product.

“We’re the only operation that I know of that has a 100% feedstock — with no diversity of that source — composts it and then sells it,” said Jonathan Whetstine, compost manager of Richer Lands Compost. “We own the hauling and now the composting. We are full circle with no middle men.”

Jonathan and his father, Roger Whetstine, man the helms at both companies. Roger runs the CMH manure hauling side and Jonathan heads Richer Lands Compost. The duo began horse manure hauling in 2014 after purchasing a client list, but it was desperation that led them to create Richer Lands Compost. As the old saying goes, “necessity is the mother of invention.”

“We hit our third truck, hired a third guy and got hauling,” said Jonathan about how their hauling business was growing fast to keep up with increasing demand in their region (south to Hwy 24, north to Watkins, east to Kiowa, and west to I-25, and including Castle Rock, Sedalia and Cherry Hills in Denver). “(A landscape company) just piled it for us, but they ran out of room. We were there four times a day, each truck, so it was a constant supply and they had to keep up with us.”


Once that facility stopped accepting, the Whetstines had to scramble.

“Before we started composting, I was looking all over the country and asking (other manure haulers), ‘okay, what do you do?’ recalled Roger about juggling massive demand for hauling equine waste with a scarce supply of dumping locations. “Every one of them, the No. 1 issue was where are you dumping it? We had kind of seen it coming, but it came a whole lot quicker than we were ready for.”

Faced with the possibility of closing their business despite a waiting list of customers, Jonathan explored commercial composting as a means to solve their dumping issues and create a saleable product. While the long term was positive, the initial obstacles seemed overwhelming.

“We had discussed composting at that point and it was too much,” said Jonathan of regulations and expenses. “I read this big rule book from the Colorado Department of Health and I was just like, we don’t have $2 million to build a site. I was thinking we were done.”

But where there is a will, there is a way. Forging ahead, he found U.S. Department of Agriculture and Environmental Protection Agency guidelines that provided hope.


“I learned some rules that changed the game,” Jonathan explained. “We are considered agricultural feedstock, so we are registered under the USDA, (which is) a whole different game. I now had an opportunity.”

Seizing that opportunity, the Whetstines carved out acreage to receive the equine waste and set up commercial composting. They began with the tried and true windrow method, using a large Aeromaster turner and following scientific guidelines to cook and cure the windrows into finished compost. Included in those regulations were mandated sampling and testing protocols.

“I have to test it and send in samples to the lab,” said Jonathan about testing the compost as well as protecting nearby surface water. “I have to look at my lab results and look at my parameters.”

Fast forward several years from their scrambling start and they are now producing a compost that is lab tested at less than 1% weed and seed germination and selling to commercial landscape clients like long-time Parker, Colo., companies Hughes Landscaping, Inc. and The Sod Guy.

“It is fantastic,” praised founder Kurt Hughes, who now contracts with Richer Lands Compost. Although Hughes was initially skeptical of a horse-based product due to its historic reputation, he is a happy customer. “No problems whatsoever,” Hughes continued. “A lot of people that do horse manure, they just throw it in a pile and leave it there for four or five years, and it still doesn’t look as good as if you roll it, cool it, add water to it, and the different things they do to make it very nice.”


The horse-based compost also had to pass strict metro ordinances.

“There are a lot of cities out there like Aurora and Denver and Castle Rock that you have to have certified compost to install in some of these yards,” added Hughes. “They sent it to them and we sent it to them (and) they both came back and said that is beautiful stuff to use in our cities. That is a big step right there.”

For 2022, CMH and Richer Lands Compost are expanding the compost side of their business, already procuring land and developing it with contractors and the county government. While compost does not narrowly target soil deficiencies the way chemical fertilizer does, the Whetstines believe their product can fill a long-term need arising due to shortages and skyrocketing fertilizer costs reported in the news today.

“It is a full circle look at growing,” said Jonathan as he acknowledged the scale issues for large farms to use compost. “It is hard to treat large farms with compost, (but) compost isn’t just bringing nutrients; it is also creating a home for everything that helps plants flourish — the microbiology, the fungi. Not only do you want the immediate benefits, but you want a long term house to where things come in and grow and benefit the plants. It is a long game.”

That long game also includes helping horse owners understand their equine waste is a boon versus a bane.

“To haul off manure helps the horse community,” said Jonathan. “It helps keep good neighbors, it helps everything and we want to keep horse people here because we like that mentality. In the future, when we expand, we will be accepting horse waste. If people haven’t budgeted for manure hauling, they can bring it to our location for a less expensive dump charge. For a bigger barn that already has employees and equipment, if they have a way to transport it, just bring it over for a smaller dump fee. And maybe we can help alleviate the environmental pressure of having their horse manure pile up on their property. So there are all kinds of ripple effects. And it is all just horse!” he summed up with a laugh. “It just kind of proves the power of the horse.”
