Loam is the kind of soil which is the most fertile and ideal for the healthy growth of plants. It is a dark coloured soil which is rich in a organic material which is good for the growth of the plants. It contains the remains of dead plants and animals which serve as natural fertilisers. This soil is made up of a mixture of sand, silt and clay. This is the ideal combination and makes the soil a rich one. It is the one found normally in gardens and ideal for farming as well.
