how the study of soil profile improves agriculture


Agricultural importance of soil profile

Definition of soil profile soil
profile is 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 profile represent 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 recognise 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

soil profile has two to four major horizon
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 soil 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 soil profile makes no sense but for me I’m going to leave some major reasons why the study of soil 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 soil 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 soil 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 soil 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
Soil profile helps the Farmer to determine the level of the drainage capacity and aeration of the soil
Soil 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
