Engineered Topsoil



Engineered Topsoil

Nature’s GREEN-RELEAF™ Engineered Topsoil is an 80/20 blend of our Certified Compost and a mixture of sand, silt, and clay.  We engineered this product to replicate a sandy loam soil. This is a type of soil that is used in plant beds and pots that require ample drainage for the plants to thrive. Soil types are based on the ratio of materials in the soil. A sandy loam soil is a mixture that is generally well-balanced, but has sand as a dominant particle type. Perfect loamy soil is ideal for most growing, and contains a mixture of sand, silt and clay. Our product has some distinct advantages over your traditional topsoil. It’s much lighter in weight and higher in organic matter content. Our Engineered Topsoil can be used as is for all your landscape or garden projects.

Novozymes Nature’s GREEN-RELEAF is a proud participant in the US Composting Council’s Seal of Testing Assurance Program (STA). This is a compost product testing, labeling and information disclosure program designed to give you the information you’ll need to get the maximum benefit from the use of our compost product. The program was created in 2000 and is the consensus of many of the leading compost research scientists in the United States. No other compost testing program is available to compost producers or compost buyers that will give you this type of detailed information. The program tests for the following parameters:
  • pH
  • Soluble Salts
  • Trace Elements
  • Nutrients
  • Organic Matter
  • Moisture
  • Particle Size
  • Stability
  • Maturity
  • Heavy Metals
  • Pathogens
