What is soil? What is its importance in human life? Explain the factors that
contribute to soil formation.
Answers
Explanation:
Soil is a material composed of five ingredients minerals, soil organic matter, living organisms, gas, and water.
Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites. We build on soil as well as with it and in it.
Scientists attribute soil formation to the following factors: Parent material, climate, biota (organisms), topography and time.
These factors interact to form more than 1,108 different soil series in Minnesota. The physical, chemical and biological properties of the different soils can have a big effect on how to best manage them.
Answer:
What is soil?
Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water. Soil minerals are divided into three size classes — clay, silt, and sand (Figure 1); the percentages of particles in these size classes is called soil texture. The mineralogy of soils is diverse.
