Clay is a very common substance. Shale , formed largely from clay, is the most common sedimentary rock.

The soil provides your plants with the vital nutrients, water and air that they require for healthy growth and development. But each plot of ground has its own blend of minerals, organic and inorganic matter which largely determines what crops, shrubs or trees can be grown successfully. Ideal soil conditions for specific crops can be created in contained plots such as raised beds or planters , but for larger gardens and landscapes it helps to understand the characteristics of the soil you have to work with. There are six main soil groups: clay, sandy, silty, peaty, chalky and loamy. They each have different properties and it is important to know these to make the best choices and get the most from your garden. Clay soil feels lumpy and is sticky when wet and rock hard when dry.

Pedology pp Cite as. It has to classify the higher units, to group the major soil types of the world according to the genesis of their basic properties and thus provide a framework, of some kind, to act as a basis for the science of pedology;. It has to provide a means of making large-scale maps for practical purposes, such as in agronomy, which often necessitates the use of detailed characteristics, that are of local importance only, in defining and naming units. It is obvious that this classification of lower units involves entirely different problems from that involved in dealing with the higher units.

Soil can be categorised into sand, clay, silt, peat, chalk and loam types of soil based on the dominating size of the particles within a soil. Sandy Soil is light, warm, dry and tend to be acidic and low in nutrients. Sandy soils are often known as light soils due to their high proportion of sand and little clay clay weighs more than sand.
