Agricultural sprayers: know the history of the machine and its functions



What are agricultural sprayers?

Agricultural sprayers are machines or equipment capable of distributing liquids in small particles. Spraying can occur by land or air, depending on the extent of activities. These machines and equipment are applied to ensure the correct dispersion of agrochemicals, nutrients and fertilizers in world agriculture.

Due to the importance in pest control and agronomic development, they are indispensable technologies in the current field to maintain productivity.

History of agricultural spraying

Agricultural spraying has been around since the first great civilizations. In Ancient Rome, smoke from burning sulfur was already used as a way to control aphids in wheat and salt plantations to control weeds. 

In the early 19th century, Chinese used arsenic diluted in water to control insects. 

It was known since that time that plant-derived products such as rotenone and pyrethrin controlled the presence of insects in crops. 

In 1865, Paris Green, a mixture of arsenic and copper, began to be used to control Colorado potato beetle populations. And in 1882 it was discovered that a mixture of copper sulfate and lime, called a Bordeaux mixture, was effective against the disease in vines called downy mildew, a fungal infection in plants.

As early as 1890, a mercury-containing powder began to be used for seed treatment, and 25 years later, a liquid formula was developed to control seed fungal pests.

At the turn of the 19th to the 20th century, the first herbicides began to appear, but the big leap in the area came in the 40s, with the rediscovery of DDT and organochlorines.

One way of understanding pest control divides chemical knowledge into three eras:

  1. Period before 1867, when odorous and irritating products such as excrement, ash, sulfur, rotenone, pyrethrum, nicotine, animal oils and petrochemicals were applied;
  2. Period between 1867 and 1939, marked by the discovery of the Bordeaux mixture and other copper formulas (with the presence of copper);
  3. Period from 1939, with the arrival of organosynthetics.

These three eras mark not only chemical technology, but also herbicide application and pest control strategies. 

Until 1868, plants needed to be rubbed or washed with cloths or brushes dipped in the mixture. Watering cans were also applied to increase application speed and uniform distribution.

Also in this period there was the practice known as benzedura, in which dusters and brooms soaked in liquids threw them over the plants.

The spurt in the development of engineering equipment for agricultural spraying begins in the second period, especially in the late 19th century. 

The growth of large-scale monoculture practices around the world favored the emergence of new application technologies due to the development race driven by major pests in plantations.

The three main ones were: downy mildew on European vines, potato beetle invasion in the US and potato scab in England and Ireland. 

The potato scab decimated the potato crop on the island of Ireland and led the region to a state of hunger and misery, reaching approximately 500,000 deaths directly caused by the problem and migration of almost a million people to other countries.

After these advances, in 1939, the explosion of growth in engineering and chemistry for agriculture, driven by the two World Wars and the technological expansion of the period, generated increasingly modern and efficient agricultural machines.

Challenges in agricultural spraying

Agricultural tractor sprayers emerged with the need for a more efficient control of the disposal of agrochemicals, as crop areas grow non-stop and pests follow the same pace in a biological race. 

As a result, it became necessary to increase the quality and precision of the applications, wasting less agrochemicals in the air or in the soil at the time of spraying. 

The process can be historically divided into 5 steps:

  1. Street count spray marking depending on boom width and crop spacing;
  2. Marking by flags placed at the beginning and at the end of the streets to demarcate the spray strip, work in a straight line similar to the first model, but on a larger scale;
  3. Ground marking carried out by 2 tractors and a steel cable with a length equal to the width of the bar applied to the rear of the first tractor with the front of the second tractor. Markings in parallel with a scarifier that scratches the ground;
  4. Light bar system with georeferenced equipment equipped with satellites and intelligent on-board computers capable of mapping the sprayed area;
  5. Autonomous system in which the machine operates alone without the need for a light bar and manual operator control. 

Today, this last system generates high precision in the application, with computers passing readings on humidity, pressure, temperature, dosage and condition of the soil. 

Types of agricultural sprayers

Agricultural sprayers can be categorized in several ways. The first of them refers to the activation, in which they are divided into: 

  • manuals: normally used for small areas and punctual actions; 
  • electrical: mechanical, with battery, dependent on energy sources for recharging;
  • fuel-powered: powered by burning fossil fuels. 

But there is still a classification by equipment configuration and activation mode. See below how they work.

Costal sprayer

Reservoir with handles, carried on the back like a backpack. It can have manual, electric or fuel activation. It depends on an operator to handle it all the time. 

Pistol Sprayer

They work with compressed air and have manual or electric activation. For manual operation, they are recommended only in vegetable gardens, orchards and small gardens.

Boom Sprayer

Bar with multiple spray nozzles normally installed on tractors. They can cover large areas in small time intervals. 

Useful for farmers facing any production volume, but typically applied to annual crops such as soybeans, corn, wheat, potatoes and horticulture in general.

Atomizing Sprayers

Machine that sprays through an air current at high speed over the plantation. Capable of reaching great distances. Usually used in perennial crops like coffee and oranges.

Agricultural sprayer parts and accessories

Sprayers (whether manual or motorized) usually have:

  • tank/reservoir for the mixture (diluted mixture of water and agrochemical component);
  • bomba;
  • agitator;
  • filter;
  • pressure regulator;
  • manometer;
  • drive set;
  • hose;
  • spray nozzle;
  • triggering device (bar or gun).

Mechanized models may have applied volume meters, GPS, computer remote control systems, thermal sensors, barometers, etc.

How to choose agricultural sprayers?

Sprayers should be chosen based on two factors: type of crop and area sprayed. 

As stated earlier, annual crops are usually served by boom sprayers coupled to tractors. While perennial crops use atomizing sprays. 

In addition, the total area calculation determines the number of machines needed (most common for atomizers, with capacity without great variation) and the maximum capacity in liters of each of them (bar sprayers can go from 400 to 4500 liters on average) . 

Maintenance of agricultural sprayers

Due to the high flow of liquids and the chemical action of many of them, agricultural sprayers depend on good maintenance to have an adequate lifespan and not cause damage or problems. Most sprayers have specialist agricultural machinery So Clean insurance . Below, we list the main maintenance activities required on the machines.


Agrochemical residues in sprayers contaminate people or animals. In addition, they mix with the new products inserted in the tanks and impair the performance and general effect.

Cleaning, therefore, becomes essential to ensure the health of workers in the field, the people living around them and nature. Therefore, it must be done at the end of every working day or at the time of product change if they occur on the same day. 

All handling when cleaning the sprayers must be carried out with the correct PPE, and it is necessary to use, in addition to water, special detergents, degreasers and other products recommended by the manufacturers of agrochemicals and fertilizers.

Parts including triggers, filters and nozzles need to be removed and immersed in water repeatedly to ensure thorough cleaning. 

Adjustment and calibration

Adjustment and calibration help correct dispersion problems and correct application can be done on different parts of the sprayer, including the nozzle. Calibration helps to verify the reliability of the process and should be done whenever consumption is above 15% of the average.

Replacement of nozzles and parts

Sprayers, like all agricultural machinery and equipment, have periodic maintenance and overhaul routines. Therefore, the parts must be replaced following the parameters recommended by the manufacturers. 

Nozzles can generate huge losses with dispersion above the planned, and when they reach deviations of 10% above the nominal flow, they need to be replaced.

Agricultural spray parameters

There are 8 fundamental parameters to perform and evaluate an agricultural spraying correctly:

  1. Dose : concentration of the active ingredient to obtain control of the target population. It can be calculated in grams/hectare or liters/hectare. The ideal value is calculated by an agronomist or forestry engineer;
  2. Application volume : Measures the amount of spray applied per unit area, affected by target, nozzle, weather conditions, plant and product type;
  3. Coverage : Amount of droplets deposited on the target in the spray, determined by product, droplet size and other factors such as plant architecture, leaf density and more;
  4. Droplet Size : Typically measured in micrometers (microns) for the diameter of the sprayed droplet. This parameter is defined as a function of the product’s mode of action (systemic or contact), climatic conditions and target situation (closed or open plantation). Also, droplet size affects nozzle choice;
  5. Pressure : Used to identify flow rate and droplet size, can be read on sprayer manometer;
  6. Wind, temperature and relative humidity : Sprays with small drops cannot occur in winds greater than 10 km/h, and activities are not recommended in temperatures below 30°C with relative humidity above 55%. If these conditions are not met, other parameters are changed to facilitate the activity;
  7. Drift : Movement of product through the air away from the target during spraying. It is, in short, the waste of product that does not reach the target. It can be influenced by wind, temperature, humidity and droplet size;
  8. Nozzle Type : Also known as spray tips. Important variable as it affects other factors.

Necessary care while spraying

Spraying is today a fundamental step in modern agriculture. However, it must be done in the right way to generate the desired results and not negatively affect people’s lives and health. 

Therefore, to be done correctly, it is necessary that quality products and machines are purchased, that the use of PPE is supervised, that maintenance and cleaning are carried out properly and that workers are trained and made aware of the importance of care. handling products, whether agrochemicals or fertilizers.

In addition, the application of the products must be done at the right times, using quality water to form the solution, respecting the climatic conditions to adapt the spraying process.

And to preserve nature and the lives around, waste must be disposed of according to regulations and good environmental practices, with the concentration of agrochemicals in appropriate quantities.

How to Get Famous on Instagram?




How to Get Famous on Instagram?


If you want to get famous on Instagram, it’s not as hard as you think. You just need to know what to do and how to do it. We have compiled some ideas and tips here so that you can go from being “nobody” on Instagram to getting more followers and likes than any of your friends!

Follow and Interact with Influencers in Your Niche

Follow and Interact with Influencers

Influencer marketing is a popular way to get your brand noticed on social media. By following influencers in your niche, you can see what they’re posting, and then engage with their content by commenting or sharing their posts. You can also reach out to them directly if you have questions about something they’ve written or posted online. If an influencer has reached out to you before, don’t hesitate to reach back! It’s important that both parties feel comfortable collaborating together so that both parties benefit from the relationship.

Post High-Quality, Engaging Content

Posting high-quality, engaging content is the most important thing you can do to get famous on Instagram. High-quality photos and videos are more likely to be shared and liked by your followers, which means they’ll show up in more people’s feeds. And the more likes and shares your post gets, the better its ranking will be in Instagram’s algorithm — which means it will show up even higher in people’s feeds than before!

So what makes an image “high quality”? It has good lighting (natural or artificial), sharp focus, and balanced exposure; it doesn’t have any obvious defects like dust spots or blurriness; it uses filters sparingly so as not to distract from its subject matter; it contains no copyrighted material from other people’s accounts…you get the idea!

If this sounds like too much work for you right now then don’t worry: just keep experimenting with different types of photos until something clicks with your audience!

Engage with Your Community

  • Respond to Comments

When you respond to comments, it shows that you care about your community and want to engage with them. This is a great way for them to feel valued and appreciated by you.

  • Post Photos of Your Followers

Posting pictures of your followers helps build a sense of community among all the users on Instagram. They will feel like they are part of something bigger than themselves, which makes them more likely to continue using the platform because they want to make sure to take advantage of everything happening within their own circles or other people’s circles!

Use Hashtags to Help You Get Famous on Instagram

Hashtags are a great way of getting more followers, likes, and comments. Hashtags help you get more views, interactions, exposure, and popularity.

Hashtags can be used in many ways to promote yourself on Instagram:

  • Use hashtags in your captions (the text description under each photo or video)
  • Use hashtags in the comments section of other people’s posts (this will increase engagement with those users)

Keep Your Bio Fresh And Attractive

Your bio is a great place to tell a story and let your followers know who you are. You can also include links to your other social media profiles, website(s), and email address in the bio section. If you have an Instagram profile then include it here too!

 Always Post Engaging Content

To get famous on Instagram, you must post engaging content. This means that your posts should be relevant to your target audience and style and theme should be consistent.

You can’t just post the same thing over and over again or use the same filters every time, either! It’s important to mix it up so that people who follow you don’t get bored with what they see in their feeds every day.

Concentrate on Your Niche

In order to get famous on Instagram, you need to focus on your niche. When you do this, it will be much easier for people in your niche to find and follow you. You also want to target a specific audience with hashtags that are relevant to them. This will help them find out about your account so they can follow it too!

If possible, try using consistent themes for each photo or video post. This can make things easier when posting content because then there isn’t as much thinking involved when deciding what photos/videos go together well enough for posting purposes; instead of worrying about whether or not something looks good next to another image (which might not look good), just post whatever comes naturally while still sticking with whatever theme(s) applies best here.”

Use Your Personal Picture

The first thing to do is take a personal picture. A professional one will not get you any followers and fame on Instagram, but a personal one can help your account grow in popularity.

You can use:

  • Your own picture
  • A professional picture
  • A view of you in your work environment (e.g., at a store or office)
  • A view of you in your home environment (e.g., cooking dinner for friends)

Or even better, post multiple photos per day!

Timeliness Matters

When posting, it’s important to consider the time of day and day of the week that you are posting. Posting at a time when your audience is online will help ensure that they see your content.

If possible, post at times when engagement rates are highest for both you and them–which may be different than what we think! For example, if most people in your target audience are teenagers or college students who sleep late on weekends (and therefore aren’t likely to be awake until noon), then it would probably make sense for you not to schedule any posts on Saturday morning because there would be no one around who could engage with them until after lunchtime.

Similarly, if many members from this same group tend not to get home from work until later in the evening (say around 8 pm), then posting something new before bedtime might not be optimal either since there would likely be little activity happening during those hours anyway (unless perhaps there were other reasons why someone might want their followers’ attention).

Focus on Your Target Audience

A good way to get noticed is by focusing on your target audience. Know who you’re targeting and what they want from your content, then deliver it consistently in a way that feels authentic to you. If this sounds like a lot of work, don’t worry: It’s worth it!

Once you have an idea of who might be interested in seeing your posts (for example, “young professionals” or “millennials”), start engaging with their accounts by liking or commenting on their posts. When someone interacts with yours this way, they’ll see that they’ve gotten your attention–and maybe even follow back!


As we’ve seen, there are a number of ways to get famous on Instagram. You can start by following and interacting with influencers in your niche, posting high-quality content that engages your audience and hashtags that help you reach out to new people who might be interested

Can Bought YouTube Subscribers Boost Your Social Proof and Credibility?




Can Bought YouTube Subscribers Boost Your Social Proof and Credibility?

Are you struggling to grow your YouTube following and wondering if buying subscribers is the solution? Look no further! In this blog post, we’ll explore whether or not purchasing YouTube subscribers can actually boost your social proof and credibility. With so many influencers and businesses resorting to this tactic, it’s important to understand the potential risks and rewards before making a decision. So grab some popcorn, sit back, and let’s dive into the world of bought YouTube subscribers!

What is Social Proof?

There’s no doubt that social proof can play a big role in convincing others to act or believe in a certain way. Consider the following example: You’re at the grocery store, picking up some milk, eggs, and bread. As you approach the checkout lane, you notice that the line is quite long and there are only a few items left on the shelf. You assume that most of those people in line must be buying the items, so you decide to buy them too.

Now consider what would happen if you didn’t see any other customers in line ahead of you. Would you still buy the groceries? Probably not. The fact that there are other people around confirms for you that this is a good idea, and makes it more likely for you to follow through with your purchase. Social proof can boost your confidence and help make decisions more easily. buy youtube subscribers

So why does social proof work? It comes down to two things: first, humans are lazy creatures by nature; second, humans like to conform to groupthink (the tendency for people to conform their actions to those around them). When we see other people doing something (like shopping for groceries), it makes us feel comfortable doing it too. And since we want others to think highly of us (based on factors like intelligence and status), using social proof can help us achieve our goals more easily.

There are several ways that social proof can influence your behavior and decisions. For

Why is Social Proof important?

Social proof is a psychological phenomenon in which people conform to the opinions of others. We tend to imitate the behaviors and attitudes of those around us. This can be beneficial, as it can lead to collective improvements. However, social proof can also have negative consequences.

For marketers, social proof is important because it can influence customers’ purchasing decisions. Buying YouTube subscribers is one way to increase your social proof and credibility.

There are three main reasons why buying YouTube subscribers can improve your social proof and credibility:

1) Buyers Trust Videos with More Views: Views are an important factor when it comes to buyers trust. The more views a video has, the more likely buyers are to trust it. As a result, buying views helps you boost your social proof and credibility.

2) Buying Views Shows Concreteness: Buying views shows that you’re willing to invest in increasing your video’s visibility. This makes buyers feel more confident that you’re serious about promoting your video and increases the chances they’ll choose you over other candidates.

3) Views Are Rewarded Time and Again: Viewers who view a video again are more likely to share it with their friends or recommend it to others. As a result, buying views boosts your social proof and credibility by rewarding viewers who take an interest in your content

How can bought YouTube subscribers help boost your credibility and social proof?

Bought YouTube subscribers can help boost your credibility and social proof on the platform. As a business, you can use bought subscribers to show that your channel is popular and reputable. This can improve your chances of being recommended by other users and increase viewership.

If you are looking to boost your social proof and credibility, buying YouTube subscribers can be a great way to do so. Not only will these subscribers support your content, but they will also help legitimize it in the eyes of others. Additionally, having more viewers means you’ll have more opportunities to sell products or services through video advertising.


Whether you’re a business owner, blogger, or vlogger, it’s important to have social proof and credibility. Buying YouTube subscribers can help increase your social proof and credibility by showing that your audience is interested in what you have to say. Additionally, buying YouTube subscribers can also help improve the overall perception of your brand or website. So if you’re looking to boost your social media presence and credibility, consider purchasing YouTube subscribers!
