5.4: Weathering and the Formation of Soil
The process of soil formation generally involves the downward movement of clay, water, and dissolved ions, and a common result of that is the development of chemically and texturally different layers known as soil horizons. The typically developed soil horizons, as illustrated in Figure 5.4.3 5.4. 3, are: O — the layer of organic matter.

Fertilizers (Mineral, Organic), Effect On Soil Physical Properties
The effect of mineral fertilizers may therefore be compared to that of straw incorporation. But when animal manure with a plant nutrient content equivalent to that of the mineral fertilizer dressing is applied, the soil receives an additional input of organic material, which contributes to the soil organic matter pool.

CEMENT RAW MATERIALS
The raw materials which supply cement works, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully. Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns.
