About us

For over 30 years, Spurt has been a commercial compost processing facility dedicated to producing STA Certified Compost, Topsoil and soil amendments for landscapers, farmers, organic growers, other contractors, and homeowners.

We are a family-owned business, committed to serving a broad range of clients in Michigan – with our facility in the Metro-Detroit area. Our focus is our community, and we engage in several donation projects to address local resilience and food access in underserved neighborhoods, support soil health education and give back to those in need.

Our soils are completely natural, made from recycled materials (yard waste, clean wood and food scraps) and designed to enhance and maintain plant and soil conditions, with precise formulas created especially for specific uses, such as:

  • Lawns
  • Flower beds
  • Organic farming
  • Athletic Fields
  • Roofing material
  • Erosion Control
  • Vegetable Gardens
  • Organic growing
  • Landscape architecture
  • DOT roadside projects

Our staff can answer any questions about our STA Certified Compost and soil amendments to help determine the best product for your application or use. Do not hesitate to contact us, even if you require our services outside of normal operating hours.
