Spreader of mineral fertilizers, advantages, how to do it yourself

To get a good harvest in the soil, you need to regularly apply mineral fertilizers and fertilizing. They will help saturate the land with useful elements that are necessary to increase fertility, which contributes to high yields.

Large farms, where a lot of land uses professional equipment, and on a summer cottage or personal plot, a manual device designed for spreading fertilizers is quite enough.

Fertilizer spreaders, their purpose

Spreaders of mineral fertilizers are presented as additional attachments, the use of which significantly speeds up the process of fertilizing the soil or sowing seeds.

Such devices are:

  • hinged
  • trailed

Sometimes spreaders are used to add sand to the soil or to spread it in winter during ice conditions. Such equipment provides high efficiency in any type of its use.

Some of the models are heavy and can perform various functions. These types of spreaders are irreplaceable.

Spreaders provide accurate dosage and even distribution of mineral mixtures over the surface of the cultivated areas, which contributes to a positive result during the cultivation of agricultural products.

Using this type of equipment will reduce the cost of purchasing the required nutritional supplements.

Some of the spreaders are attached to agricultural machinery using special attachments. This type of technique helps to enrich the soil with minerals using the spread method.

Fertilizer spreaders

Fertilizers can be:

  • trailed
  • hinged
  • disk
  • pendulum

Agricultural equipment for applying mineral fertilizers may have additional functions. They can mix, grind, transport.

They are usually divided into 4 main groups.


Such devices are highly productive in distributing micronutrients and sowing seeds at minimal pressure.

The device includes a body, conveyor, dispenser, drive. To control sowing, it is necessary to change the speed of the conveyor and the size of the gap, which is what the shutter is for.

The most common are trailed devices. In appearance, they resemble a trailer. For this reason, they received such a name. However, the accuracy of fertilizer distribution is not at the highest level.


This type of spreader is able to match the power of a tractor. The device consists of a frame, a device for hanging to a tractor and a hopper. In addition, there are safety grids that prevent large elements from entering the unit.

In the lower part of the equipment there are special funnels designed for scattering mineral mixtures.

A distinctive feature of any of the attachments is the presence of spreading discs. In the event of a malfunction, they can be replaced.

Fertilizers during the operation of the unit are fed by a shaft to the surface of the spreading discs from the hopper.

The discs rotate in opposite directions, which contributes to an even distribution of fertilizer over the treated surface.


This type of spreader is equipped with special discs and vanes made of stainless steel and a cardan shaft. To adjust the amount of fertilizer spread, there are special dampers that can be controlled directly from the tractor cab.

By changing their position, the amount of distribution of nutritional supplements over the surface of the field is controlled. In order to prevent clumping of mineral additives and the ingress of large particles into the device, it is equipped with agitators and special meshes.


This type of spreader is produced only by foreign companies. For this reason, they are in rather low demand on the Russian agricultural market.

The main working body of this installation is not rotating discs, but a special tube that reciprocates from side to side - swings.

To ensure strength and long-term performance, this part is made of high quality plastic. Thanks to a special shaft, the tube reciprocates.

Still, it should be noted that this type of spreader is inferior to disc spreaders. In addition, they make quite a lot of noise and unevenly distribute nutrient mixtures over the surface of the land plot.

The principle of operation of spreaders

Fertilizers are poured through protective grids into the hopper, inside of which there is a tedder. It ensures an even supply of granules to the dampers. Then they fall on the surface of the spreading discs, on which there are special blades that capture the granules.

Under the influence of centrifugal force, mineral substances are scattered over the surface of the treated area.

The additional possibility of adjusting the position of the blades ensures even distribution of nutrients over the entire width of the grasping surface.

To select a specific position, the seeding rate, the characteristics of the fertilizer used and the speed with which the tractor moves during top dressing are taken into account. The unit is driven by a power take-off shaft.

What are the advantages and disadvantages

Any technique has its own advantages and disadvantages. The main advantages are:

  • fast delivery of nutrients;
  • the ability to process large areas;
  • time saving;
  • uniform coverage of the surface of the site with fertilizers;
  • the introduction of the composition occurs only during the movement of the device;
  • some models have the function of adjusting the amount of applied mixtures;
  • the ability to apply for other agricultural purposes.

The main disadvantage is the rather high cost of the equipment. Summer residents and landowners, in whose use are relatively small plots of land, make fertilizer spreaders on their own.

To process large areas, you need to buy professional equipment in a specialized store. A wide range of presented models allows you to choose the best option that is suitable for a specific area.

How to make a manual fertilizer spreader with your own hands

The manual device needs to be pushed across the field by yourself, and this is not very convenient. Nevertheless, it is quite possible to do it yourself. The basis of the device is a pair of traveling wheels and a box for nutrient mixtures.

11 holes are drilled in the bottom of the box, covered with plates that rotate. A pair of ejectors are installed above the plates.

In addition, a turner can be connected. Wheels, while driving, transmit torque to the discs, the ejector shaft and the agitator.

With the help of a similar design, fertilizers from the box fall onto the rotating discs, and then relatively evenly onto the ground.

We make a homemade organic fertilizer spreader

There are two simple devices for applying liquid organic fertilizers that can be successfully used in the country or in the garden. The attachments consist of an axle, two wheels and a handle. Differences in fertilizer containers.

A plastic bottle with a capacity of five liters with liquid nutritional mixture is suspended from the handle of the device, so that it is at a distance from the ground.

A pair of tubes is threaded through the bottle cap: long and short; before starting work, it is necessary to blow through the short one so that the liquid fertilizer fills the long tube. Then the liquid flows by gravity.

Bend a metal pipe with a diameter of 24 millimeters on a special machine. The bottom of the tube is the axis. Wheels are installed on it.

The wheel located on the right side is fixed with washers and cotter pins on both sides. The left wheel is secured with cotter pins, right bracket support ring, washer and plug.

The distance between the wheels is 70 centimeters. Holes with a diameter of 2 millimeters are drilled every 2 centimeters.

Another device is designed to apply powder or granular fertilizer. The plywood box is filled with nutrient mixture. A through axis passes through the side walls of the box. She is wearing wheels.

Inside the box there are 4 blades on the axis. They rotate with the axle when the wheels are moving and serve as a kind of turner. There are 26 holes drilled in the bottom of the box with a diameter of 8 millimeters. The same number of holes were drilled in the metal plate, only their diameter is 6 millimeters.

The location of the holes in the bottom of the box and on the plate must match. The plate moves along the bottom of the box to the right and left by 4 millimeters. The location of the plate is fixed with a special lever.

Openings can be closed and opened by moving the lever. When they are open and the device moves, fertilizer is poured out of the holes.
