The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation).

What does good topsoil look like?
Good topsoil should crumble in your fingers. You should feel the grit in it which indicates minerals that are needed for your plants like phosphorus, magnesium, and calcium. Avoid soil that is too hard, as it indicates low organic matter. Soil that clumps up into balls or large chunks is too rich in clay.

What is the first layer of soil?
