  6. 6. Putting organic matter in a pile and letting it decay is not composting Agresource Inc. 100 Main St. Amesbury MA 01913 800-313-3320 www.agresourceinc.com
  7. 7. What is Compost?Compost is a Soil Amendment that: Provides organic matter Supplies nutrients Stimulates microbial activityCompost is not: Top soil or loam Fertilizer Pesticide or a biological control agent Agresource Inc. 100 Main St. Amesbury MA 01913 800-313-3320 www.agresourceinc.com
  8. 8. Compost QualityNot all composts are the same  Moisture content  Texture and particle size  Organic matter content  pH, soluble salts, and nutrients Agresource Inc. 100 Main St. Amesbury MA 01913 800-313-3320 www.agresourceinc.com
  9. 9. Compost QualityProduct characteristics depend upon: Feedstocks: Biosolids vs. Food Wastes vs. Manures Bulking Agents: Wood chips vs. Sawdust vs. Leaves Type of processing: Screened vs. Unscreened Age: Active vs. Aged Agresource Inc. 100 Main St. Amesbury MA 01913 800-313-3320 www.agresourceinc.com
  10. 10. Types of Compost(by type of feed stocks) Leaf and Yard Compost Biosolids Compost Manure Compost Food Waste Compost Wood Ash Paper fiber (SPF) Agresource Inc. 100 Main St. Amesbury MA 01913 800-313-3320 www.agresourceinc.com
  11. 11. Compost Properties Organic Matter: Undecomposed residuals, active and dead microbes (Biomass) and the products of decomposition (Humic matter) Nutrients: macro (N-P-K) and micro nutrients (e.g. Cu, Bo, Fe, Mg, Mn, Zn, etc.) Ash and grit Agresource Inc. 100 Main St. Amesbury MA 01913 800-313-3320 www.agresourceinc.com
  12. 12. Compost UsesExamples of product use: Establishing lawns and turf Root zone mix for sports fields Top dressing lawns and sports fields Planting beds Tree and shrub planting mix Root zone mix for constructing golf greens Potting media component Soil amendment for vegetable production Wetland construction and remediation Infiltration basins for storm water management Agresource Inc. 100 Main St. Amesbury MA 01913 800-313-3320 www.agresourceinc.com
  13. 13. Choosing The Right Compost for the Right Use Finer texture for topdressing (<1/2 inch acceptable; <3/8 inch preferable) Coarser texture for mulch (< 1 inch) pH, soluble salt: highly dependent on plant choice and application rates Aged for potting mixes Avoid compost with high silt/clay for sports field mixes Low nitrogen and phosphorus near water resources Agresource Inc. 100 Main St. Amesbury MA 01913 800-313-3320 www.agresourceinc.com
  14. 14. Optimizing Organic Content in Soil Specifications 3% to 10% often specified  3% unnecessarily low for lawn areas  10% too high for lawns 5% to 8% for lawns (low traffic impact) 4% to 6% for sports fields (high traffic impact) Balance organic content with infiltration rate
  15. 15. All Composts are Not the Same Comparison of Different Composts on Infiltration Rate All Mixes: 80% Sand: 20% Compost Silt Clay Total Infiltration RateCompost A 3.33 % 1.06 % 4.39 % 16 In/HrCompost B 6.07 % 0.69 % 6.76 % 12 In/HrCompost C 5.43 % 2.03 % 7.46 % 4.6 In/Hr
