Characteristics of horticultural peat

Why is horticultural peat so important for horticulturalists? Because its unique characteristics give unique results!

The “technical” aspect: unrivalled on all accounts

The following are qualities that make peat moss a unique and sought-after product in horticulture and agriculture, whether it is as a principal component in growing media or as a soil amendment:

• It improves mineral soil structure.
  • It increases water retention in sandy soils (light soil), which helps reduce the leaching of nutrients. Peat moss can retain up to 20 times its weight in water.
  • It increases clay soil (heavy soil) aeration, which helps to increase drainage. The oxygen that is then more abundant in the soil allows roots to breathe and grow, and allows the absorption of nutrients.
• It is less dense and lighter than mineral soil.
• It improves soil buffering since decomposed peat moss is highly tolerant to pH variations.
• It improves the cation exchange capacity (CEC), which helps to retain minerals, releasing them over time (prevents the leaching of fertilizers).
• It is a source of organic matter; it stimulates soil microbial activity by contributing microorganisms beneficial for plant growth.
• It is a natural resource free of weeds and contaminants.

Peat moss allows plants to grow in aerated and well-structured soil, guaranteeing healthy, vigorous plants. Peat moss is also an approved component in the production of organically certified produce.

The environmental aspect:
breaking the myths

Peat moss harvesting in Canada is heavily regulated. Producers work in partnership with internationally recognized research bodies to establish responsible management practices.

The careful use of Canadian peatlands, and the research and investment in techniques of rehabilitation, are positive and concrete markers on the industry’s environmental record.

In Quebec and Canada, peatlands are managed by responsible businesses—businesses that respect their environment, that are proactive and innovative in their development and their research into sustainable options, and that are committed to the well-being of the community and those who work for them.
