Welcome To Soil Not Dirt Farm!

We specialize in building high quality compost for soil health, using local ingredients from the western slope of Colorado.

We offer bulk compost and delivery! For estimates or any questions, please contact us at soilnotdirtcompost@gmail.com or 970-261-3344.

Our compost is also available for bulk pick-up per cubic yard outside of Delta, Crawford, and Paonia.


For over 15 years we have focused on creating a balanced compost with high beneficial bacteria and fungal communities. The goal is to build biodiversity and a nutrient-dense product, which is important for crops and landscapes. Our compost goes through a 6+ month aerobic thermophilic and mesophilic process. We use a diverse range of ingredients to help promote a wide range of beneficial microbes and nutrients.

To produce our compost, we use a turner that helps homogenize and aerate the compost in windrows. Water is sprayed into the windrows while turning using a water wagon. We pay close attention to moisture levels which allows the microbes to go through the full process of breaking down material, and building beneficial microorganism communities.

We turn our compost at least 5 times over a 15-day period with temperatures above 130 degrees for that time period per USDA and NOP Standards. These are the guidelines to kill pathogens and weed seeds. But we go beyond these standards to provide fully finished stable compost.

What makes our compost different? 

  • Ingredients: We are selective about what we compost to provide a biodiverse nutrient-dense product. Some of this material is free to us, and other material has a cost to them. We have never been paid to receive material. We source non-GMO ingredients, and also use trusted sources of materials so we don't have herbicides/pesticides and heavy metals that can carry over into finished compost. Also with using a wide range ingredients you receive a wide arrange of nutrients and microbes. 
  • Truly finished compost: We put in the energy to fully compost the material we start with- that means it looks and smells like soil when you receive it. To get it to this point, it needs time, correct moisture, and oxygen. Have you ever received compost that stinks and is black-ish? Your compost should smell like rich earth, be a dark chocolate brown color, and starting ingredients should be unrecognizable (besides woody materials:). 
    • Time. Time leads to the full cycle of the carbon to nitrogen ratio. The time it takes for material to compost depends on what is being compost. Woody ingredients need longer than vegetable waste. 
    • Moisture. The correct levels of moisture let material actually break down especially in our dry climate. Beneficial biology is vibrantly alive in 40%-60% moisture levels. Microbes will start to go dormant the drier the material becomes, and it is unknown when/if they will come out of that dormancy. 
    • Oxygen. The good guys of biology love oxygen, and the bad guys thrive in no oxygen. If compost stinks really bad it most likely lacked oxygen through its process, and with time, turns black in color. Also, compost getting too hot can actually burn material leading to a burnt black color.
  • Biology: A healthy gut comes from healthy soil. Should we be scared of getting great soil/compost into our mouth/gut? We don't think so at SND, and actually think it's beneficial  if it has the good guys in it. Humans have evolved with these good microbes over time, and it's a symbiotic relationship. With that, our finished compost has the dominance of beneficial bacteria, fungi, nematodes, protozoa, and arthropods. And we love watching our kids play in it! This is because of the extra energy of time, moisture, and oxygen that we put forward in composting. ***** Disclaimer: Only eat soil/compost if your specialist recommends it;)

2026 Compost

Extra steps we are taking: After our compost is screened and stable, we turn it one last time with an inoculation of a local fungal vermicompost Johnson/Su style compost. This reintroduces biology that might be lost with multiple turnings/screening of the compost. It also brings in beneficial microbes that we aren't able to cultivate due to the windrow style of composting we do. We strive to provide the best compost we can that will help feed your soil with nutrients and biology. This is a list of inputs we used.

  • Sheep/cow/horse manure with wood chip/sawdust bedding
  • Sweet corn & onions
  • Virgin aged sawdust/wood chips
  • Previously screened out wood chips/compost



2026 Pricing

All compost is screened and sold by the cubic yard. 

1-26 yards........  $89 per cubic yard

27+yards..........  $79 per cubic yard

Plus your local sales tax and delivery - Delivery is available for a fee around the western slope of Colorado. We can help outsource/locate trucking if needed, and we will also load your sourced dump truck/semi. There are three bulk compost pickup locations outside of Delta, Crawford and Paonia by appointment only. We will provide an address when we set up the appointment.

Please contact us at 970-261-3344 or soilnotdirtcompost@gmail.com.

Compost is screened: We screen with a 1/2" x 1" screen.
*Note: Due to the fact that composting involves turning "waste" into a very beneficial product there is always non-organic material and small rocks present. This is very minimal in our compost.

Delivery Options

I do deliver some myself, and outsource the rest depending on the quantity you are needing.
