Compost

How Compost is Made
The compost is produced at the city’s compost facility located at the end of Davidson Drive. It is a mixture of wood chips, dehydrated bio solids from the city’s wastewater facility, and straw from the nearby thoroughbred racetrack. The compost analysis consists of:
  • Moisture - 56%
  • Nitrate nitrogen - <0.5 mg/kg
  • pH - 7.6 S.U.
  • Phosphorus - 12,000 mg/kg
  • Potassium - 14,000 mg/kg
  • Salts - 21.0 mmhos/cm (millimohs per cm)
  • TKN - 19,000 mg/kg
Benefits of Compost
  • Improves the soil structure, porosity and density, thus creating a better plant root environment
  • Increases infiltration and permeability of heavy soils, thus reducing erosion and runoff
  • Improves water holding capacity, thus reducing water loss and leaching
  • Supplies a variety of macro- and micro-nutrients
  • May control or suppress certain soil-borne plant pathogens
  • Supplies significant quantities of organic matter
  • Improves cation exchange capacity (CEC) of soils and growing media, thus improving their ability to hold nutrients for plant use
  • Improves and stabilizes soil pH
  • Can bind and degrade specific pollutants
Using Compost
Compost has a variety of uses such as general landscaping, flower beds, house plants, gardens, lawns, shrubbery, trees, etc. View some of the examples of how to mix and measure compost that follow:

Established Lawns
Apply 3/4 to 1 cubic yard of compost per 1,000 square feet to a depth of 1/4 to 3/8 inch. This is best done in early spring and late fall when conditions are cool and moist.

New Lawns
Apply 3 cubic yards per 1,000 square feet to a depth of 1 inch, and rototill to a depth of 4 to 6 inches.

Flower Boxes & House Plants
Mix two parts compost, one part peat moss, and one part perlite or vermiculite.

Flower Garden
Apply 3 cubic yards of compost per every 1,000 square feet to a depth of 1 inch.

Vegetable Garden

Apply 1 cubic yard per 1,000 square feet of garden once per year in late fall or winter.

Recommendations
We recommend you wear garden gloves when working with compost along with other garden materials.
