Agriculture is the backbone of any nation's economy. It plays a crucial role in providing food, employment opportunities, and raw materials for various industries.
The success of agriculture heavily relies on a multitude of factors, known as the factors of production. They include land, water, labour, finance, and a management system. These factors are essential for the efficient and effective functioning of the agricultural sector.
Please read on agricultural machines and it's uses here.
Factors of production simply refers to the resources utilized by people to produce goods and services. With regards to agriculture, they serve as the building blocks through which farmers achieve their aim.
In this article, we will explore land as a factor of production in agriculture, alongside its significance.
Land is perhaps the most fundamental factor of production in agriculture. The availability of agricultural land is crucial for cultivating crops and rearing livestock.
From the above paragraph, the two main uses of agricultural land are listed below:
The cultivation of crops.
The raising and rearing of animals.
Please read on the definition of various agricultural terms here.
Meanwhile, understand that land can also be very useful in building various agricultural agencies and institutions across a country.
A good agricultural land is dependent on various factors such as its quality, topography, fertility of its soil and accessibility to water sources. The availability of these factors will greatly impact agricultural productivity.
Please read on the ways to prevent soil erosion here.
Farmers must carefully evaluate the aforementioned factors before choosing the land for their agricultural activities. In fact, a good agricultural land should have the following characteristics:
It should have a good fertile soil for the cultivation of crops.
It should be easy to work in.
It should be situated close to one or more water sources.
The land must have a good topology. It should not be sloppy. Rather, it should be a plain (level) land.
It should have a good water holding capacity, and not waterlogged.
Its particles should have appropriate spacing such that it becomes easily aerated.
The soil particles should have a good structure and texture.
You can read on the types of agricultural practices here.
Land in general (including non agricultural land) will have the following characteristics:
It is free gift of nature.
It has no cost of production; that is: it cannot be produced.
It is not movable.
It is fixed in supply.
The price of land is dependent on its location.
It is somewhat indestructible.
The reward of land is rent. However, understand that land may be traded in the barter system.
It is worthy of note to reiterate that land plays a crucial role in determining the success and productivity of farming activities. For students interested in the field of agriculture, understanding the significance of land as a factor of production is vital.
One of the primary reasons why land is crucial in agriculture is its role in providing a suitable environment for plant and animal growth. In this regard, soil quality is a determining factor in the success of cultivating crops, and rearing animals. However, one of the difficulties encountered by farmers is seen in the acquisition of land, especially in developing countries.
Please read on the role of government in agriculture here.
Farmers can acquire land through the following ways:
Inheritance from their parents.
Allocation of land to people who wish to farm. Such allocation could be from the government, community rulers, relatives, elders and friends.
Leasing and renting of land from landowners.
Purchase of land directly from landowners.
People may acquire land as gifts from others.

The composition of the soil, including its pH level, nutrient content, and drainage capacity, directly affects the growth and yield of crops. Different crops have specific soil requirements, and the availability of suitable land plays a significant role in meeting those requirements.
The proximity of agricultural land to water sources (river and lakes) is crucial. This is true because it greatly influences the irrigation methods used and the overall productivity of the farming activities. Meanwhile, recall that adequate water supply is necessary to ensure the healthy growth of crops, especially in regions with limited rainfall.
You can read on the differences between plants and crops here.
Land availability and accessibility also play a significant role in determining the viability of agricultural activities. Students interested in agriculture must consider factors such as land ownership, land use regulations, and land tenure systems. These factors can affect the ease of access to land and the ability to utilize it for agricultural purposes. Understanding land laws and regulations is crucial for students planning to pursue a career in agriculture.
Please read on soil explained with its composition here.
Below are the general importance of land (in agricultural and non agricultural activities):
Agricultural activities which include growing of crops and rearing of animals occurs on land.
Forestry and wildlife resources are present on land.
Factories, schools, hospitals and roads are built on land. These will generally improve the economy.
A different mineral resource such as crude oil, gold, coal, etc is derived from land.
Bodies of water such as rivers, lakes and sea which are part of the land area are used for transportation purposes which aid foreign trade.
It is the host of other factors of production in bringing about meaningful productive activities.
Recall that land also serves as a habitat for livestock, and plays a crucial role in animal husbandry practices. Adequate land space is essential for raising animals, providing them with grazing areas, and ensuring their overall well-being. The availability of land resources for livestock farming directly impacts the scale and profitability of animal husbandry activities.

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 characteristics of gymnosperms:
Their seeds have cones that protect them.
Sepals and petals aren't present in their cones.
Stigma and style are absent.
They do not produce fruits. Only seeds are formed.
Companion cells are absent.
Sporophyll form the cones.
Anther and filament are absent.
The ovules are not present in the ovary.
Gymnosperms do not possess flowers.
Please read on the anatomical differences between gymnosperms and angiosperms here
The flower is the reproductive organ in plants' sexual reproduction. In order to achieve a successful sexual propagation or reproduction in plants, the floral parts of the flower are utilized.
The floral parts of a flower consists of the followings:
Sepals
Petals
Stamen
Carpel
The stamen is male portion of a plant. It consists of the anther and filament.
The carpel (or pistil) is the female portion of the plant. It consists of the stigma, style and ovary.
An organism will be considered a pest if it does one of the followings:
Attack crops and eat its seeds, roots, stem, leaves and flowers. Examples are locust and grasshoppers.
Cause damage to stored food, fruits or other agricultural produce. Some may even urinate or deaficate on these products. Examples are rodents, cockroaches and mice.
Attack and kill farm animals like goats, sheep and cattle. Examples are foxes, wild cats and snakes.
Act as disease vectors. A vector is an organism that carries parasite and other disease causing organisms, without being affected; but when they introduce the parasites into their host, such host becomes infected with disease. Examples of vectors are rodents and mosquitoes.
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.
