Friction angle or also known as angle of repose of soil is the subtended angle formed between the side slope with the vertical of a loose heap of the soil. This can also be determined by the triaxial shear test on soil conducted in laboratory.
To support a potted tree and prevent it from blowing over in the wind, choose a sturdy pot that provides stability and weight. You can use stakes driven into the soil to anchor the tree, attaching the trunk to the stakes with soft ties to avoid damage. Additionally, placing the pot in a sheltered location, such as near a wall or fence, can help reduce wind exposure. Regularly check the ties and stakes to ensure they remain secure as the tree grows.
If you drive in a stake with the pointy end facing down, it is easier to push it into the soil.
Water can decrease the angle of repose of soil by reducing the friction between soil particles, making them more likely to slide over one another. This can lead to soil instability and increased risk of landslides or erosion.
To secure your tent on rocky ground, use heavy-duty tent stakes designed for rocky terrain. Look for stakes with a strong, durable material like aluminum or titanium. Use a hammer or mallet to drive the stakes into the ground, aiming for gaps between rocks or softer soil patches. Consider using additional guy lines or rocks to anchor the tent for extra stability.

It depends on the moisture content of the soil, the acidity of the soil as well as other factors. "But practically, the answer is forever."
To fix grass that has been driven on, you can try aerating the soil, reseeding the damaged areas, and avoiding further traffic until the grass has had a chance to recover.

Cassava can be planted using several methods, primarily through stem cuttings. The most common method involves selecting healthy, disease-free stems, cutting them into 20-30 cm pieces, and planting them horizontally or at a slight angle in well-prepared soil. Another method is using whole stems or stakes, which are planted directly into the soil. Additionally, some farmers may use tissue culture techniques to propagate high-quality cassava varieties.
