If you are looking for the answer of why what is soil profile, you’ve got the right page. We have approximately 10 FAQ regarding why what is soil profile. Read it below.
Differentiate soil profile and soil horizon
Ask: Differentiate soil profile and soil horizon
A soil horizon makes up a distinct layer of soil. The horizon runs roughly parallel to the soil surface and has different properties and characteristics than the adjacent layers above and below while the soil profile is a vertical section of the soil that depicts all of its horizons.
why do you think soil texture, structure, or color changes
Ask: why do you think soil texture, structure, or color changes with profile depth?
Deeper in the soil, the organic pigment coats surfaces of soil, making them darker than the color inside. Humus color decreases with depth and iron pigments become more apparent. … Soil color is a study of various chemical processes acting on soil.
What is the difference between a pedon and a soil
Ask: What is the difference between a pedon and a soil profile?
A soil profile is smaller than a pedon. It is exposed by a two-dimensional vertical cut through the soil. A pedon description is commonly based on examination of a profile, and the properties of the pedon are inferred from the properties of the profile.
what is soil profile and give its importance
Ask: what is soil profile and give its importance
Answer:The soil profile is an important tool in nutrient management. By examining a soil profile, we can gain valuable insight into soil fertility. As the soil weathers and/or organic matter decomposes, the profile of the soil changes.
in what way soil profile replenish
Ask: in what way soil profile replenish
The nutrients are replenished in the soil by crop rotation. Changing the crops for every season will keep the land fertile. When one type of crop drains the nutrients in one season, then in the nest season plant different type of plant which will give back these nutrients to the soil.

the characteristics used for classification of soils are those of
Ask: the characteristics used for classification of soils are those of the soil profiles and include the items enumerated below.Do the soil profiling. this can be drawn and presented in illustration board.
The granules’ shape
SAND grain shape characteristics
CLAY grain shape characteristics
a particular surface
The bulk of soils are classified as SANDS or CLAYS:
Gravelly sands and gravel-sands are examples of SANDS. Sand grains are either the refractory components of rocks that have been broken down by chemical weathering or fragmented rock particles that have been generated by physical weathering. The form of sand grains is typically rotund.
CLAYS contain silty clays and clay-silts; pure silts (such as places created by windblown Löess) are uncommon. Chemical weathering of rocks and soils is the most common source of clay grains. Clay particles are flaky in appearance.
Between SANDS and CLAYS, there are significant changes in engineering behavior (for example, permeability, compressibility, and shrinking/swelling potential). These variances are influenced by the shape and size of the soil grains.
5. This is a soil particles are arranged from the
Ask: 5. This is a soil particles are arranged from the surface soil to the parent rock.
What do you called of this?
a. Soil profile
b. Soil texture
Some Clay particles are so small that ordinary microscopes do not show them
i hope that right
If you are a soil profile, what level/ horizon are
Ask: If you are a soil profile, what level/ horizon are you? and why?
The horizons are: O -(humus or organic) Mostly organic matter such as decomposing leaves. The O horizon is thin in some soils, thick in others, and not present at all in others. A -(topsoil) Mostly minerals from parent material with organic matter incorporated.
A soil profile is a vertical section of soil like the diagram above. It allows you to examine the structure of soil. A soil profile is divided into layers called horizons. … The A horizon is where there is most soil life and is sometimes called topsoil.
The simplest soils have three horizons: topsoil (A horizon), subsoil (B horizon), and C horizon.
%%%%%I still don’t know the answer but that’s a conclusion
Why do you think understanding the soil profiles is important
Ask: Why do you think understanding the soil profiles is important to soil health and to mankind?
Organic matter includes any plant or animal material that returns to the soil and goes through the decomposition process. In addition to providing nutrients and habitat to organisms living in the soil, organic matter also binds soil particles into aggregates and improves the water holding capacity of soil.
