Ground contact lumber is specifically designed to be in direct contact with the ground, making it more resistant to decay and rot. Pressure treated wood, on the other hand, is treated with chemicals under pressure to make it more durable and resistant to decay, but it may not be suitable for direct ground contact.
Pressure treated wood is treated with chemicals to resist decay and insects, while ground contact wood is specifically designed for direct contact with the ground. Ground contact wood is more durable and resistant to moisture, making it ideal for outdoor applications where the wood will be in direct contact with the ground. Pressure treated wood is suitable for above-ground applications but may not be as resistant to moisture and decay as ground contact wood.
Ground contact wood is specifically treated to resist decay and insect damage, making it more durable for outdoor use, especially in direct contact with the ground. Pressure treated wood, on the other hand, is treated with chemicals under pressure to increase its resistance to decay and rot, making it suitable for outdoor use but may not be as durable as ground contact wood in direct ground contact situations.
The best pressure treated wood for ground contact is typically either ACQ (Alkaline Copper Quaternary) or CA (Copper Azole) treated lumber. These types of treated wood are specifically designed to resist decay and insect damage when in direct contact with the ground.
Pressure-treated lumber with a rating of UC4A or higher is recommended for ground contact applications. This type of treated lumber is specifically designed to resist decay and insect damage when in contact with the ground.
A cedar fence is naturally resistant to rot and insects, making it durable with minimal maintenance required. However, it can be more expensive upfront compared to a pressure-treated fence. Pressure-treated fences are chemically treated for durability but may require more maintenance over time. Overall, cedar fences are more durable and require less maintenance, but they are typically more costly than pressure-treated fences.

It is probably not a good idea as toxic preservatives in the pressure treated wood can leach into the compost and then become incorporated in plants and their fruit and vegetables grown in that compost later. But using appropriate lining materials to completely prevent any contact between the pressure treated wood and the compost inside would avoid this problem. So a complete answer to your question is not simple.
Pressure treated wood is treated with chemicals to resist decay and insects, making it more durable and resistant to environmental pressures compared to sealed wood, which is simply coated with a protective sealant. Pressure treated wood is better suited for outdoor use and can last longer in harsh conditions. Sealed wood may require more maintenance to maintain its durability over time.
Older pressure treated lumber known as CCA was treated with 3 substances, Chrome, Copper, and Arsenic. Newer treated lumber intended for consumer contact is now treated with different chemicals, such as copper/boron. Lumber NOT intended for consumer contact, such as buried or submerged lumber may still be CCA treated. PS- it is not a good idea to burn ANY treated lumber. If it kills bugs and fungi, it is likely not real good for you, either.
Pressure treated fences are typically more durable and longer-lasting than cedar fences due to the chemical treatment process that helps prevent rot, decay, and insect damage. However, pressure treated fences require more maintenance over time, such as regular staining or sealing to maintain their appearance and protection. In terms of cost, pressure treated fences are generally more affordable upfront, but cedar fences may be more cost-effective in the long run due to lower maintenance requirements.
what is the difference between woods
The best type of wood for ground contact applications is pressure-treated lumber, specifically treated with chemicals to resist decay and insect damage. This type of wood is more durable and long-lasting when in contact with the ground compared to untreated wood.
