What is the meaning of Soil Taxonomy?
Soil taxonomy is the system of soil classification used for mapping and classifying soils by the National Cooperative Soil Survey in the United States; it is used in many other countries as well. It employs a unique mnemonic system based on Greek, Latin, or other root words for assigning names to taxonomic classes.
What is a soil family?
A soil family category is a group of soils within a subgroup and describes the physical and chemical properties which affect the response of soil to agricultural management and engineering applications.
How do you find the soil family?
The differentiating criteria for families of mineral soils are particle size, mineralogy, reaction and calcareousness, depth, soil temperature, and soil moisture regime.
What are the purposes of soil taxonomy?
Soil classification systems are established to help people predict soil behavior and to provide a common language for soil scientists. The National Cooperative Soil Survey and the USDA developed the Soil Taxonomy classification system, which is used worldwide.
What is the pH of the soil?
Most soils have pH values between 3.5 and 10. In higher rainfall areas the natural pH of soils typically ranges from 5 to 7, while in drier areas the range is 6.5 to 9. Soils can be classified according to their pH value: 6.5 to 7.5—neutral.
What is silt water?
Silt is a solid, dust-like sediment that water, ice, and wind transport and deposit. Silt is made up of rock and mineral particles that are larger than clay but smaller than sand.
What is soil pH and its formula?
Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale goes from 0 to 14 with pH 7 as the neutral point.
Why do we need conservation areas in Nigeria?
The need to conserve representative samples of natural vegetation was recognized in Nigeria over thirty years ago. Before 1950 only two conservation areas had been laid down but at present there are seven in operation.
What are the major natural resources of Nigeria?
Although Nigeria mainly focuses on Crude oil as its major economic source, it still uses some other natural and mineral resources to improve its standard of living and the economy. Natural resources are substances that occur naturally without the influence of man and can mostly be used for human consumption and economic growth.
Where can I find barite in Nigeria?
Nigeria is hugely blessed with a large number of Barite deposits. Barite or Baryte (BaSO4) mineral resources are made up of Barium sulfate and come in a wide range of crystal forms and colors. Locations: Large numbers of quality Barite are found in Cross River State in areas like Yala, Ikom]
