What is the appropriate depth for burying tarp edges to properly anchor them?

Burying tarp edges is crucial for effective fumigation, as it helps to create a sealed environment that minimizes the escape of fumigants and maximizes their effectiveness. The appropriate depth for burying tarp edges is typically around 4 inches. This depth is sufficient to hold the tarps in place against external factors such as wind and soil movement, while also ensuring that the tarp remains sealed against potential leaks.

Burying the tarp edges too shallow, such as only 2 inches, may not provide adequate stabilization and can lead to lifting or displacement. On the other hand, while burying the edges deeper, such as 6 or 8 inches, might seem beneficial for securing them, it may complicate the retrieval process and potentially require more labor and time without providing significant additional benefits to the sealing effectiveness. Therefore, a depth of 4 inches strikes an optimal balance between securing the tarp effectively while also allowing for practical management during the fumigation process.
