Agricultural Machines and their Uses:

Mechanised farming is a system of farming whereby agricultural machines are utilized on farmlands. The use of agricultural machines greatly increases the farmer's output and productivity. For this reason, they are used on large farmlands; thus replacing the primitive simple farm tools.

Please read on Agricultural Tools and their Uses here.

Below are various agricultural machineries and their functions:

 

1. Tractor

Tractor - Len Academy

An tractor serves a variety of purposes. In agriculture, one of such purpose is to effectively pull or push other agricultural machineries like planters, rollers, plough, reaper, balers, mowers, combine harvester and so on.

They are also used for carrying or hauling different type of large materials from one point to another.

Please read on the Roles of Government in Agricuture here.


2. Irrigation Sprinkler

Irrigation Sprinklers - Len Academy

Irrigation sprinklers are also referred to as sprinklers or water sprinklers.

They are used to water large areas of farmland. They may also be used for controlling dust particles generated from various activities carried out on land.

You can attempt LEN ACADEMY Examination Questions for Agricutural Science, JSS1, First Term here.


3. Plough

Plough - Len Academy

They are pulled by tractors and help to cultivate the soil, preparing it for sowing. They do this by turning over the upper layer of the soil in order to expose fresh nutrients to its surface. Through this action, small plants, weeds and other particles present on the soil becomes buried, thus bringing about their eventual breakdown and decomposition.

Please read on the Causes of Soil Erosion here.


4. Cultivator

Cultivator - Len Academy

A cultivator helps to efficiently mix the soil with organic fertilizers and other materials.

The cultivator is also used for the preparation of seedbed. It is able to carry out this function because it controls weeds and warms the soil on an agricultural land. Through this process, the planted crops are able to grow on the soil which now contains less weed, adequate water and more nutrients.

Please read on Agricultural Land and its Uses here.


5. Reaper

Reaper - Len Academy

They are also driven by a tractor. The reaper helps to cut crops into a size of about 3-4 inches above ground level. The crops are then carried via its conveyor belt.

Note: A reaper is very useful for harvesting crops like cereals, grasses, oats and barley.

6. Subsoiler

Subsoiler - Len Academy

They are tractor driven and are used for tilling the soil. A subsoiler acts as a tillage machine that breaks up and loosens the soil. They prove to be useful in farmlands with compacted soils.

Please read on Soil Erosion and Types of Soil Erosion here.


7. Agricultural Rollers

Agricultural Rollers - Len Academy

They are pulled by tractors and are used to level the soil by breaking large clumps of particles present on the surface of the soil.


8. Harrows

Harrows - Len Academy

They are commonly termed a set of harrows.

They perform a tillage function like the plough and subsoiler; but that of the harrows occur at the surface of the soil.

Functionally, a harrow breaks and level up the soil's surface.


9. Mowers

Mowers - Len Academy

Mowers are agricultural machines used mainly for cutting grass (and forage crops).

Due to the manner at which the grasses are cut, hay and silage becomes the end result of the cut grasses; after which they are placed into rows referred to as windrows.

Please read on Anatomical and Structural Differences between Gymnosperms and Angiosperms here.


10. Balers

Balers - Len Academy

A baler, also called a hay baler is used for compressing crops that had been cut or raked; for instance - silage, hay and flax straw. The baler aid in compacting the cut crops into bales so that they can be easily moved from one point to another. Also, the crops becomes easily stored when in bales.

Please read on various Agricultural Terms and their Meanings here.


11. Combine Harvester

Combine Harvester - Len Academy

The combine harvester is simply referred to as combine. It perfoms at least two functions.

First, it reaps (harvests) grain crops. Next, it threshes it, separating the grain kernels from their seed coverings and other chaff that may be present around it.

In summary, the major operations carried out by the combine harvester are reaping, threshing and winnowing.

You can read on Asexual Propagation in Plants here.


12. Planter

Planter - Len Academy

A planter (usually towed behind a tractor) functions to plant or sow seeds in rows throughout the farmland.

The planter plants the seeds down the soil in a definite manner along rows at regular intervals.

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.
