Commercial farming refers to an agricultural business involving the growing of crops and rearing of animals with the aim of selling them to make profit. Commercial farming can also be termed as agribusiness.
Please read the introduction to commercial farming here.
Below are 13 characteristics of commercial farming:
Commercial farming is practiced on large farmlands. This land can span hundreds of acres.
Please read on agricultural land and its uses here.
The ultimate aim of commercial farming is to make profit from the crops produced and animals reared.
It is capital intensive to start and run.
One type of crop may be grown on many hectares of land (mono cropping), giving rise to plantations.
Agricultural machines are always required in commercial farming.
Please read on agricultural machines and its uses here.
It requires the use of agrochemicals like fertilizers, insecticides and pesticides in large quantities.
The best of seeds and animal species are selected and utilized for commercial farming. Also, the agrochemicals are usually of high yielding varieties. This is crucial towards reducing its negative effects on the atmosphere and environment at large.
Please read on the functions of the atmosphere here.
Commercial farming are often managed by large companies due to their large scale production of crops intended for use and distribution, both locally and overseas.
Individuals can also embark on commercial farming as long as they have the experience, expertise and capital to commence and run the business.
Please read on sole proprietorship here.
Skilled labourers are hired and wages (or salaries) are paid.
Commercial agriculture usually requires advanced storage and other processing facilities.
You can read the concept of division of labour here.
The products of commercial farming serves as food for man, raw materials for industries and generation of foreign exchange into the country.
Use of advanced technologies is a crucial part of commercial farming. For this reason, commercial farming is practiced throughout the year. As an instance, the farmers do not have to wait for the rainy seasons since a properly implemented irrigation system can substitute for the rains.

Amazing facts in Agricultural Science
Cows technically have one stomach, not four. However, a cow's stomach has four compartments. These are: rumen, reticulum, omasum and abomasum
Peanuts are legumes and not nuts
Although plants neither see nor hear, they can recognize their siblings and even give them preferential treatments
Squirrels do plant more trees (through their actions) than an average human in their lifetime. They often hide their acorns and nuts underground and forget about them
Cows have got the ability to walk up stairs, but not down stairs
A group of cows is called a team, drove or herd.
People just prefer to call them herd
NOTABLE POINTS IN Agricultural Science
Below are the classification of crops based on their uses:
Oil crops
Vegetable crops
Latex crops
Drug and Medicinal crops
Beverage crops
Fibre crops
Fruit crops
Root and Tubers
Legumes
Spices
Cereals
All crops are plants but not all plants are crops. Below are some instances:
Weeds are considered as plants, not crops.
Parasitic plants are not necessarily crops. Examples of parasitic plants include mistletoe, corpse flower and striga.
Carnivorous or insectivorous plants are not necessarily crops. Examples are sundew, venus flytrap and pitcher plant. The image below shows a carnivorous plant (venus flytrap).
Meanwhile, always understand that all crops are plants, and they are grown for food, money or something beneficial.
Below are some of the problems of agriculture in Nigeria:
Lack of mechanized farming
Poor government policies
High cost of fertilizers
Lack of education
Lack of storage facilities
Bad road network
Poor research facilities
Please read a detailed explanation on the problems of agriculture in Nigeria here.
Secateurs are agricultural tools.
Secateurs are also referred to as pruning shears or hand pruners.
It looks like a pair of scissors.
It’s used for trimming flowers and leaves.
It is also used for pruning the branches of shrubs.
An example of an agricultural tool is the hoe. It is shown below:
We have a variety of hoes.
