Answer 1

I think this is what you are looking for.

Sand - It is grainy soil which holds little or no compost or humus. It drains very well and as a result, does not hold water well at all. It is also lacking in minerals and micro-nutrients needed by you plants. Roots of plants can easily grow and expand through sand.

Clay - This is the second major type of soil. It is largely the opposite of sand. It retains water, and does not drain well. Heavy clay soils can act as a pot, holding water for days as rainwater ever so slowly seeps through it. Roots can actually drown, as there is no air in the soil. Roots have a hard time pushing through it ,and tend to ball up.

Loam - This soil contains a mixture of clay, silt and sand, as well as some organic matter. It retains water well, yet is loose and contains plenty of air pockets for roots to breathe. Best of all, it is rich in minerals and nutrients vital to plants growth and development.

Humus - Soil containing a rich mixture of decomposed plant or animal matter. It is rich in minerals and nutrients and vital to plants' growth and development.
