Soil Chemistry

March 23, 2013

Introduction:

Soil is essential to life on earth is one of the most complex of materials. A complex combination of inorganic and organic solids, fluids, and gases, soil provides a challenging material for research, especially for scientists who are not professionals in soil chemistry. This clear, generally appropriate reference provides chemists and ecological scientists with the background they need to evaluate soil, understand their results, and develop new analytical methods for soil.

Introduction to Soil Chemistry:

The most important soil characteristics that effect research and the techniques, substances, and equipment used to determine the structure and quantity of soil constituents.

Soil Chemical Properties:

Soils in wet environments and certainly those developed on acid stones, such as granite, will are generally acidity. Soils in high rain fall areas are generally acidity because the rain fall leaches the soil of many of its nutritional value which otherwise help to keep the pH higher.

Acid soils can be enhanced by including lime to soil. This is a common agricultural practice where farm soils need to be managed at a pH from 5.5 to 7 in order to grow a variety of plants.

Soil pH:

Soil pH is probably the most generally calculated soil chemical property and is also one of the more useful. Like the heat range of the human body, soil pH indicates certain features that might be associated with a soil. Since pH (the adverse log of the hydrogen ion action in solution) is an inverse, or negative, operate, soil pH reduces as hydrogen ion, or level of acidity, increases in soil solution. Soil pH increases as level of acidity reduces.
