That's what farming was like before technology and the Industrial Revolution. It was incredibly time-consuming, and most people didn't have an opportunity for education or any other job. Technology revolutionised agriculture – but it was not without its negative effects.

Use of Technology in Agriculture
Before the Industrial Revolution, agriculture was the largest source of employment in Europe. Families, including children, often worked six days a week to keep their crops growing. Many people were subsistence farmers.
Subsistence farmers grow food to meet the needs of themselves and their families.
But during the 1700s and 1800s, things began to change. Large open fields were separated using hedges or low stone walls. Smaller farms were leased to the public, and new technology forms of technology (such as the seed drill, the plough, and new breeding methods) became popular.
Seed Drill: traditionally, farmers planted seeds manually. This led to a lot of wastage – seeds were frequently blown away by wind, or eaten by birds. New horse-drawn seed drills would drill a hole into the ground to drop seeds into, then cover the hole. The seed drill enhanced crop yields by fivefold.
Triangle Plough: new ploughing technology used an iron blade instead of a wooden one, which was easier and lighter to handle. It only required two horses and one person to operate (compared to the traditional plough requiring four oxen, a ploughman, and an ox driver). New triangle ploughs were quicker, more efficient, and reduced costs for farmers.
Selective Breeding: farmers began mating the largest and strongest animals, to produce offspring with the best characteristics. Sheep were cross-bred to maximise wool and meat production.
The new technology and breeding methods meant that farmers could sell crops to the urban population, and make profit. However, peasants and poorer villagers were forced to become paid employees, or seek work elsewhere.
Technology in Agriculture: Examples
Let's look at some examples of agricultural technology.
| Factor | Description |
| Availability of Energy | Energy (whether electrical, mechanical, or thermal) helps farmers to control building temperatures, and operate heavy machinery or drive farm vehicles. |
| Agrochemicals | Agrochemicals are chemical products used in industrial agriculture. Examples include fertilisers, pesticides, and insecticides. |
| Machinery and Equipment | Machinery and equipment is faster and more effective than manual labour, saving farmers time and money. |
| Irrigation | Irrigation is the process of applying controlled amounts of water to land to assist in crop production. |
| Transport Infrastructure | Developments in transport allow farmers to transport produce quickly and cheaply. |
Impact of Technology on Agriculture
How have these examples of technology impacted agriculture?
Availability of Energy
Access to gas and electricity has revolutionised agriculture. Farmers use energy to heat and cool buildings, such as greenhouses and cattle sheds.
Heating cattle sheds can increase efficiency. The cows don't expend as much energy keeping warm. In turn, this increases their rate of weight gain.
Energy availability also allows farmers to operate machinery and farm vehicles. Farm machinery and vehicles are heavy and powerful, requiring large amounts of energy to operate.
Combine harvesters can weigh up to 20 tonnes.

Using energy to manipulate temperature and operate machinery increases agricultural efficiency.
Agrochemicals
We're going to focus on two types of agrochemicals: fertilisers and pesticides.
Fertilisers contain essential plant nutrients, such as nitrogen (N), phosphorous (P), and potassium (K). They maximise plant growth by incorporating these nutrients into the soil.
Pesticides are used for killing pests, such as unwanted neighbouring plants, insects, fungi, and bacteria. They reduce damage and disease suffered by crops.
Pesticides encompass insecticides, fungicides, and weedkillers.
Machinery and Equipment
Since the first petrol tractor was invented in 1889, farm machinery and equipment has reduced the requirement for manual labour. One machine can do the work of many labourers, making physically demanding and time-consuming tasks much easier. This decreases production cost and increases crop yields, thus enhancing farm income.
Mechanisation of agriculture in the UK produced yields 80% higher than the European average.
Irrigation
Primarily, irrigation allows farmers to grow more crops. Yield is high – the plants are not subject to water stress.
Water stress is physiological stress suffered by a plant due to a lack of moisture.
Furthermore, irrigation allows farmers to make use of previously unproductive areas of land, and produce food outside its regular growing seasons.
Irrigation also acts as 'insurance' against seasonal rainfall variability, or droughts.

Transport Infrastructure
Effective transport infrastructure helps develop agriculture and reduce rural poverty. Affordable transport reduces food prices, increases farmers' income, and helps reduce the price of food in urban areas.
After WWII, improvements in transportation enabled farmers to access distant markets, making it increasingly profitable to specialise in a particular crop.
Importance of Technology in Agriculture
Technology has revolutionised agriculture and boosted food security.
Food security is defined as reliable access to a sufficient quantity of affordable and nutritious food.
Food security is closely tied to development, and linked to many of the United Nation's Sustainable Development Goals. It affects health and physical development, and the opportunity for education and non-agricultural livelihoods. Unfortunately, 30% of the world's population is deemed as food-insecure, so there is still a long way to go.
Experts have produced the Planetary Health Diet to enable global food security without compromising the environment. It's mostly plant-based, but allows some flexibility regarding meat, dairy, and fish. However, the majority of dietary protein should be sourced from pulses, legumes, and nuts.
Environmental Issues in Technology and Agriculture
Although new technology can benefit agriculture, it can have detrimental impacts on the wider environment.
Availability of Energy
Agriculture relies heavily on energy derived from fossil fuels. Burning fossil fuels to release energy produces carbon dioxide, a greenhouse gas. Greenhouse gases trap solar radiation in the atmosphere, heating Earth's surface and contributing to climate change.
Agriculture is responsible for 11% of global greenhouse gas emissions.
Burning fossil fuels releases harmful atmospheric pollutants, such as:
Carbon monoxide
Oxides of nitrogen
Particulate matter
Sulfur dioxide
Mercury
Agrochemicals
Although agrochemicals enhance agricultural productivity, they can severely impact the environment.
Excessive use of fertilisers can run off into water bodies, causing eutrophication. The high nutrient input triggers rapid algal growth, leading to toxic algal blooms that deplete the water of oxygen, killing marine organisms.
Pesticides can be toxic to non-target organisms, including beneficial insects and microorganisms. Overuse of pesticides can disrupt natural communities. Furthermore, pesticides can have direct impacts on humans. Long-term exposure is associated with:
Hormone disruption
Immune suppression
Reproductive abnormalities
Reduced intelligence
Cancer

Machinery and Equipment
Construction of farm machinery and equipment uses metals. They are finite resources, extracted from the Earth using damaging mining techniques.
Plus, using heavy farm equipment leads to soil compaction. Topsoil becomes squashed into an impermeable layer, restricting the movement of air, water, and key nutrients.
Irrigation
Although irrigation promotes plant growth, it has negative impacts elsewhere. Modern irrigation techniques affect groundwater levels, affecting river flow and water availability.
Groundwater is subterranean water, stored in soil and rock crevices.
Irrigated areas also experience a higher evaporation rate. This disturbs the atmosphere, even affecting rainfall downwind!
Other effects of irrigation include:
Water logging
Soil salinisation
Ecological damage
Socioeconomic problems
Transport Infrastructure
Like agriculture itself, the majority of the transportation industry relies on fossil fuels, resulting in greenhouse gases and atmospheric pollutants. Extracting fossil fuels from the Earth (whether on land or offshore) causes pollution and disrupts natural communities.
Furthermore, construction of transport infrastructure and vehicles themselves is associated with pollution, landscape disruption, and use of finite resources.
I hope that this article has clarified technology and agriculture for you. Remember that technology (such as availability of energy, agrochemicals, machinery and equipment, irrigation, and transport infrastructure) has maximised agricultural productivity and efficiency, but can have detrimental impacts on the environment.
