The art and science of soil cultivation, crop production, and livestock care is agriculture. For human consumption, it entails preparing both plant and animal products. This is along with distributing them to markets. Agriculture produces most of the food and fabrics in the world. They also produce leather, wool, and cotton. It also produces paper and wood for construction. These products, as well as the agricultural methods used, can vary from one region to another.

How did Agriculture Start
Agriculture’s expansion helped civilizations advance over the course of centuries. Prior to the widespread adoption of agriculture, people devoted the majority of their time to finding food. They spent their time searching for and hunting wild animals and gathering wild plants. People began gradually mastering the cultivation of cereal and root crops about 11,500 years ago. They settled down to a life that is based around farming.
By 2,000 years ago, agriculture was a major source of income for a large portion of the global population. Scholars don’t know why this switch to farming took place. But climate change might be to blame for it.
During growing crops first, people also began taming and domesticating wild animals. Domestication refers to the adaptation of wild plants and animals for human use.
It’s likely that rice or corn was the first domesticated plant. As early as 7500 BCE, Chinese farmers grew rice.
The dogs were there for hunting. They were the first animals to be domesticated. The next domesticated animals were probably sheep and goats. Cattle and pigs were also brought under human control. Many of these creatures have been targeted for their meat and hides. Generally, many of them serve as sources of milk, cheese, and butter as well. Over time, people started using these animals, like oxen, for transportation, pulling, and plow work.
People were able to produce extra food thanks to agriculture. When crops failed, they could use the extra food or exchange it for other goods. Due to extra food, people were able to do non-farming activities.
The increase in Agriculture
Formerly, nomadic people were kept close to their fields by agriculture. This also sparked the growth of permanent settlements. Linking was through trade. In some places, new economies were so prosperous that new cities and civilizations started growing. Mesopotamia (modern-day Iraq and Iran)’s Tigris and Euphrates Rivers. The Nile River in Egypt was the site of the earliest civilizations built on intensive agriculture.
Importance of Agriculture
In order to meet the world’s development objectives, healthy, sustainable, and inclusive food systems are essential. Agriculture development is one such tool that holds the power to end extreme poverty. It can also boost shared prosperity and feed around 9.7 million people by 2050. For raising the incomes of the poorest, the agriculture sector is two to four times more effective. This is when comparing it to the other sectors. Agriculture is also necessary for economic growth. It accounts for 4% of the global gross domestic product (GDP). In some least-developed countries, it can account for more than 25% of GDP.
What are agrochemicals in Agriculture?
Agrochemicals in the agriculture sector are pesticides, herbicides, or fertilizers to manage ecosystems. Undeveloped versions of these fertilizers have been for millennia. This was done in order to improve crop yields and control pest populations.
The earliest use of this dates back to around 2500 BC. Formerly, the Sumerian farmers were using sulfur compounds in order to reduce insect populations. Doing this also reduced the subsequent risk of pest-related famine.
An evolution in synthetic chemical manufacture has vastly improved pesticide processes to cater to the growing global population. This consequent increase in food demand. However, plant pests and diseases can destroy up to 40% of the world’s crops. This is even with the effective use of pesticides.
What are the types of agrochemicals in Agriculture?
Implementation of a concerted effort to actively use a wide variety of agrochemicals. To guarantee consistently high-quality food for widespread consumption, the maintenance and control of the global food supply are equally important. The types of agrochemicals in agriculture are:
- Pesticides or chemicals are substances put in crops to destroy insects and other organisms, weeds, and fungi that could spoil crop yields
- Synthetic fertilizers like ammonium nitrate, encourage crop growth by saturating it with soils with nutrients.
- Acidifiers and liming agents, alter the pH levels of soils to suit the planting properties of given crops.
- Soil conditioners like gypsum, which is designed to condition soils with high sodium (Na) contents to improve planting conditions;
- Growth hormones, or synthetic chemicals, speed up animal and plant growth.
Engineering crops with synthetic herbicide resistance is one of the newest and most innovative agrochemical techniques. In fact, they even produce their own insecticides.
How are the agrochemicals in agriculture made?
Given the various classes or types of modern agrochemicals, there are various production techniques. However, they frequently rely on large-scale production procedures that start with unique chemical building blocks.

Introduction to Pesticides
To begin with, pesticides are chemical substances. They kill the pests. Pesticides are made from biological agents. Like viruses, bacteria, antimicrobials, or disinfectants that can deter, incapacitate, or kill pests. Using pesticides is so common that it is almost synonymous with plant protection. In other words, they get rid of or manage a variety of agricultural pests that can hurt crops and livestock and lower farm productivity. Insecticides kill insects, and herbicides kill weeds. Rodenticides kill rodents. Fungicides to control fungi, mold, and mildew are the four most popular pesticides.
What are the Types of Pesticides?
According to the types of pests they kill, there are six types of pesticides.
- Insecticides – insects
- Herbicides – plants
- Rodenticides – rodents (rats & mice)
- Bactericides – bacteria
- Fungicides – fungi
- Larvicides – larvae
Similarly, according to their biodegradability, there are two types
Biodegradable: Biodegradable substances are those that can be converted into harmless compounds by microorganisms and other living things.
Persistent: On the other hand, persistent ones are those whose decomposition may take months or years.
What are the effects of Pesticides?
For instance, pesticides can save farmers, which is above all their benefits. This is by defending crops from pests and insects. Here are a few more of its top advantages:
- Controlling plant disease vectors and pests.
- Controlling organisms that cause trouble and disease in humans and animals.
- Controlling organisms that damage other human endeavors and built environments.
Some toxic sides of the chemicals are:
These toxic chemicals release purposefully into the environment just like the intent. Despite the fact that each pesticide is for killing a specific pest, a sizable portion of them ends up somewhere else. They end up in our food, the air, the water, the sediments, and so on. Pesticides can pose risks to human health. As a result, it can give immediate effects like headaches and nausea to long-term effects like cancer and reproductive harm.
Additionally, using them reduces the soil’s overall biodiversity. The soil’s quality is higher and it can retain more water. In conclusion, it is essential for plant growth if there are no chemicals in the soil.
