How can the base of a ladder be made more stable on grass or gravel?

Using the ladder feet in spike position contributes significantly to stabilizing a ladder on uneven or soft surfaces like grass or gravel. When the spikes are deployed, they penetrate into the ground, offering a firmer grip and anchoring the ladder more securely in place. This prevents the ladder from slipping or sinking into the ground, which can happen on soft surfaces, making it considerably safer for use.

A flat base, while potentially helpful, may not provide sufficient grip on softer surfaces. Adding weight can help, but it might not address the instability caused by the ground itself. Adjusting the angle can improve balance but won't necessarily secure the base against slipping if the ground is too soft. Therefore, using the ladder feet in spike position is the most effective method for enhancing stability in these conditions.
