What is the CEC value for horticultural grade peat moss?

Cation Exchange Capacity (CEC) is a crucial property in horticulture, particularly concerning soil and growing media. It measures the ability of soil or media to hold and exchange cations, which are positively charged ions that plants need for growth.

Horticultural grade peat moss typically has a CEC value ranging between 7 to 13 me/100cc. This range indicates that peat moss can effectively retain essential nutrients and provide them to plants over time, which is vital for healthy plant development. The porous structure of peat moss allows for good aeration and drainage while still holding moisture and nutrients, making it an excellent choice for various growing applications, particularly in potting mixes.

In summary, the correct CEC value for horticultural grade peat moss is well-established within the 7 to 13 me/100cc range, reflecting its effectiveness as a growing medium in retaining and providing nutrients to plants.
