TRUE or FALSE
Land, a free gift of nature, is included as one of the three most important parts of the earth; the others being water and air.
Land is also be considered to be the lithosphere on earth.
Note: The lithosphere is the solid part of the earth where life is found.
Agriculture Land can be defined as the solid and arable part of the earth where agricultural activities can be carried out.
Agricultural activities include the growing of crops and rearing of animals.
Note: Agricultural activities can also be carried out on water.
From the introduction above, Land can be summarised to serve 2 purposes. These are
According to the edaphologists (those who are concerned with how the soil affect plants), it is believed that land should be used for agricultural purposes.
On the other hand, the pedologist are of the opinion that land should be used for non agricultural purposes.
Non agricultural purposes of land can be classified include 4 uses. These are:
1. Residential Use of Land
2. Commercial Use of Land
Please read on the Advantages and Disadvantages of Road Transport here.
4. Recreational Use of Land
However, it is the physical and biological characteristics of land that suggests how it may be used; for instance, land with fertile soils are ideal for agricultural activities and may be likely used for agricultural purposes.
Agricultural land can be classified under the following headings:
A crop is a cultivated plant that is grown for income or subsistence.
Crops can be put into 6 categories.These are:
Note: Land for the cultivation of crop must be properly managed such that its nutrients are constantly preserved. For this reason, agricultural practices like crop rotation, irrigation, bush fallowing, fertilizer and manure application should be encouraged in order to retain and improve soil fertility.
A variety of animals can be reared in Agriculture. Forms of animal rearing include:
Note: Agricultural Science as a subject has got its various technical terms.
A wildlife reserve is a region where different kinds of wild animals are kept and protected in order to avoid their extinction; while also aiming to generate income from them.
Animals preserved as wildlife include lions, elephants, crocodiles and snakes.
The land required for wildlife do not necessarily need to be fertile; neither should it be occupied by numerous trees (as seen in a forest).Please read on Tropical Rainforest and Savanna here.
The presence of wildlife reserve in a nation will provide 2 important benefits:
Note: The indiscriminate killings of wild animals are forbidden in a wildlife reserve center.Please read on the Roles of Government in Agriculture here.
Below are some major wildlife (game) reserves in Nigeria:
A forest is an ecosystem dominated by a variety of trees and animals.
The land required for the evolution of a forest does not have to be too fertile. Also, it will do no harm if the land is prone to erosion.
Allowing agricultural land to grow into forests can prove significant for the following reasons:
Below are some important forest reserves in Nigeria:

Amazing facts in Agricultural Science
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
There are about 630 different kinds of carnivorous plants.
Carnivorous plants are plants that derive some or most of their nutrients by consuming small animals, especially insects.
Carnivorous plants are also referred to as insectivorous plants.
Some example of carnivorous plants include sundew and Venus flytrap.
