The type of soil that is best for a plant depends on the type of plant. For cacti, the soil should be sandy, loose and quick to drain. For vegetables and most other plants, a sandy loam soil is the most effective. This is a soft, darkly colored, finely textured soil that drains well yet retains moisture. This type of soil allows oxygen to get to the plants' root systems while holding and providing moisture. It also has enough of a structured texture to provide physical support for plants as they grow.
