Soil profile improves Agriculture. Agricultural importance of soil profile. Definition of soil profile. this defined as the vertical section of the soil showing series of horizontal layers of different types of soil.. horizontal layers in soil profile are called Horizon
A soil profile in an area of the humid tropics such as the forest zones may have about 4 fairly distinct Horizons. First thing that is noticed in a soil profile is the colour of the soil. Horizons in a soil sectionrepresent colours
So definitely The horiizons will surely show you different colours of soil
After the colours found in the soil profile Horizons, the next thing you will recognize is the texture all particle sizes which increases in size in from the top to the bottom these two characteristics of soil profile and label the different Horizons to be identified identified
What are Horizons of Soil Profile
The A-horizon; this horison is also called the topsoil. This top horizon contains more organic matter than other Horizons seen in soil profile. The topsoil is the most Weathered and lesched of all the soil Horizons. Most agricultural crops especially shallow crops that have shallow roots which derive their nutrients from the top soil e.g legumes and vegetables
B-horizon . Horizon B is known as the subsoil is the next immediately after the top so it is rich in minerals which are carried or leached down by percolating water. B Horizon always suitable for the cultivation of crops that have deep roots like cocoa rubber orange oil palm trees
C-horizon . This group of horison is also called parent materials. They represent the type of material from which topsoil and subsoil are derived. Group in s-profile is are parent materials which are small fragment of rocks that are unweathered and found at the bottom of the soil profile.
D-horizons. This horizon is also called the bedrock. This horizon is found at the bottom of the bedrock in soil-profile and they are large rock materials
Importance of soil profile to agriculture
Sometimes one is tempted to ask study of s-profile makes no sense but for me I\’m going to leave some major reasons why the study of s-profile is very very important and key to agricultural development
Some of the major important aspect of soil profile of Farming activity is listed below
Level of soil fertility. With the study of s-profile it is now easy to determine the level of soil fertility at topsoil represent high level of soil fertility
Soil profile helps to know the type of crops to be grown in an environment. Aspect of profile help the Farmer to know the type of crops to grow for example shallow-rooted crops like cowpea,
groundnut are grown in the topsoil while deep-rooted crops are grown where the subsoil is sticker
Aspect of soil profile in helping agricultural development is about root penetration of crops. Is a simple logic 3 found out with the study of s-profile being in place we can understand and determine the kind of soil that have parent rocks closer to the subsoil that is not good for agricultural production and planting of crops that have high deep-rooted system
S-profile helps the Farmer to determine the level of the drainage capacity and aeration of the soil
S-profile helps a qualified farmer or tech farmer to determine and understanding the percolation capacity of a given land
These point listed up there are just a few but are not limited to them alone. Thank you for reading up of today you can contribute to this site by reaching out to our common bus and leave us a comment and get back to you as soon as possible

Average Output and Marginal Output.
As Mr. Kola Balogun employs one labour to work on his one hectare farm, 10 tons of yam were produced. As more and more labour are employed in every successive round of production, the total output continues to increase from 10 to 30, to 60, to 120 and so on. But as the fifth (5th) labour was used or employed, there was a drop in production from 120 to 100. This is the stage at which the law of diminishing returns sets in as every additional unit of labour brings about a decrease in the total output
Importance of the law of diminishing returns
- Proper combination of factors of production: The law of diminishing returns helps the entrepreneur to combine properly the factors of production to prevent wastage
- Changes in scale of production: The law of diminishing returns helps entrepreneurs to change the scale of production through the variation of the quantities of all input
- It ensures efficiency: As more and more variable factors are added to a fixed factor, it eventually comes to a profitable level and productivity and efficiency are maintained using labour requires little or no formal education.
They do not use mental effort,
rather, they make use of physical effort or energy in production, hence their jobs are popularly referred to as brown collar jobs.
