Soil Engineering: Common Terms and Definitions Ground ...
Desiccation – the drying of a soil. When soils are dried, either naturally or artificially, their engineering properties change. As the soil dries, the pore water is drawn to the particle contact points and a soil suction force develops. This causes the soil to become overconsolidated.

Topic 6: Properties of Soil
Introduction Soils have many different properties, including texture, structure or architecture, waterholding capacity and pH (whether the soils are acid or alkaline). These properties combine to make soils useful for a wide range of purposes. Soil properties govern what type of plants grow in a soil or what particular crops grow in a region.

Limestone: The Calcium Carbonate Chemical Sedimentary Rock
Limestone is used as a filler in a variety of products, including paper, plastic, and paint. The purest limestone is even used in foods and medicines such as breakfast cereals and calcium pills. Limestone is also the raw material for making lime (CaO) that is used to treat soils, purify water, and smelt copper. Lime has many additional uses in the chemical industries.

Cations and Cation Exchange Capacity Soil Quality
Cation exchange capacity (CEC) is a measure of the soil's ability to hold positively charged ions. It is a very important soil property influencing soil structure stability, nutrient availability, soil pH and the soil's reaction to fertilisers and other ameliorants (Hazleton and Murphy 2007).

What Is Soil Texture? |
According to Colorado State University Extension, soil texture is defined by the size of the particles that make up the soil. Soil texture typically is categorized into three types: sand, silt and clayey. Sand has larger particles and feels gritty. This coursetextured soil is comprised of sand particles between medium and coarsesized particles.

Soil that's loose has much less bearing capacity than the original soil. That's why it is so important to compact the trench bottom (use a vibrating plate compactor for sand or gravel soils, and a jumping jack compactor for silt or clay). If you don't compact that soil, you could get 1/2 inch of settlement in just the first 6 inches of soil.

Choosing Between Materials (A3671) Corn Agronomy
Limestone dissolves extremely slowly, allowing it to neutralize soil acidity only in the solution immediately surrounding each lime particle. The only way to speed the process is by using finer particles and distributing them evenly throughout the soil. If lime is mixed thoroughly with the soil, the soil pH will rise within a few weeks after .
