Soil Compaction Handbook

The response of soil to moisture is very important, as the soil must carry the load yearround. Rain, for example, may transform soil into a plastic state or even into a liquid. In this state, soil has very little or no loadbearing ability. Moisture content of the soil is vital to proper compaction.

Soil Texture: Definition, Determination and Importance

Definition of Soil Texture: Texture means size of the particles. Soil texture is the average size of the soil particle which depends on the relative proportion of sand, silt and clay in the soil. If the proportion of sand in the soil is increased, the average size or the soil particles increases and the resultant soil becomes coarser in texture.
