More Peat, Please
The previous yr has confirmed troublesome for a lot of growers who have been unable to amass the peat merchandise or product volumes they wanted. Many turned to various peat supplies when and the place doable to fill the void of decreased peat provides.

It is vital for all peat customers to know that this doesn’t imply “we’re operating out of peat in Canada” however as a substitute it signifies that because of a moist summer season and different logistical challenges, peat was not in a position to be extracted on the volumes desired. They additionally can’t simply open extra bogs to extract extra peat very simply. This course of takes seven to eight years to perform, due to this fact there isn’t a “fast repair”. The producers are nonetheless closely centered on peatland restoration on older bogs as a part of their efforts to return these pure areas again into functioning ecosystems and carbon sinks.
Coconut Coir and Wood Products
