Good for Soil and the Planet

Healthy soil is the backbone of farming, gardening, and landscaping. When soil isn’t getting the right nutrients, plants and crops will suffer.

Composed of sustainably manufactured premium compost, SoilBuilder enhances soil health and protects the planet.

  • Reduces irrigation requirements up to 50%
  • Reduces stormwater runoff up to 50%
  • Reduces pollutant loads in stormwater runoff
  • Improves percolation for better drainage
  • Holds more nutrients at the root zone
  • Improves nutrient uptake
  • Reduces compaction for better root development

Choosing the Right Compost

Premium compost increases the organic matter in soil and replenishes the soil microbes responsible for nutrient uptake and improving water management. SoilBuilder is rich in both macro- and micro-nutrients, giving plants a well-balanced diet.

McGill SoilBuilder is a versatile product designed to meet a range of needs. Use it as a soil amendment or top-dressing in lawn and garden, or as a component of soil blends and on-site manufactured topsoil.

What’s in a Bag

Each bag of SoilBuilder contains 1 cubic foot (about 40 lbs.) of premium compost manufactured from a variety of blended feedstocks that include:

  • Woody materials
  • Yard waste
  • Agricultural by-products
  • Biosolids
  • Food and food processing waste

SoilBuilder in Action

To refresh your lawn or turfgrass areas, SoilBuilder can be mixed into soil for replenishment or raked into the surface of turfgrass prior to seeding or sodding to lock in moisture and add organic nutrients.

When topsoil is thin or non-existent, mixing SoilBuilder premium compost with existing soil helps build and improve poor topsoil creating the foundation for a healthy growth environment.

Using SoilBuilder in landscaping projects encourages faster green-up after sod installations and seeding and extends a lawn’s green season in both spring and fall.
