Carbon dioxide emissions in agriculture
8 mins read |

Alongside many sectors that contribute to the world’s economy, agriculture leads nearly all of them. In the U.S. economy alone, it’s estimated that the crops, seafood, and even the livestock generated add up to more than $300 billion annually.

When the food services and also other types of agriculture-related products are also added, then, the total impact is estimated to be more than $750 billion to the gross domestic product.

With that said, agriculture together with fisheries mainly relies on the climate. With the changes and mostly the increase of carbon dioxide (CO₂) and temperature are more likely to adjust the harvests in some of the areas across the globe.

The general climate changes can make the growth of crops, livestock keeping, and even catching fish extremely hard across the planet.

Ways to reduce carbon dioxide emissions in agriculture

Carbon dioxide emissions in agriculture can be lowered by the use of several efficient methods in the agricultural systems. The major way is through lowering the greenhouse gas emissions that include carbon and even nitrogen. Below are some of the ways that you can use to lower such kinds of emissions in agriculture:

Managing manure and livestock

Management of both manure and livestock plays a crucial role in managing the amount of carbon dioxide and even other emissions that are produced in agriculture.

Below are some of the ways that can be adopted to help in the reduction of emissions generated from manure and livestock:

  • Apply rotational grazing to handle the carbon in the soil
  • Embrace livestock feed additives
  • Choose better quality feed that lowers the amount of methane produced from enteric fermentation
  • Carefully handle the manure to lower the amount of methane and nitrous oxide by covering all manure storage facilities, optimizing manure use via nutrient management plans, and even preventing methane from escaping and burning from the manure storage.

Soil Conservation and carbon removal

Agricultural ecosystems are known for keeping high levels of carbon levels. Below are some of the methods that you may use to avoid the increase in carbon:

  • Lowering tillage
  • Lowering bare fallow
  • Coming up with agroforestry systems
  • Increasing the growth of cover crops
  • Advocating for rotational grazing
  • Managing nitrogen and carbon levels through nutrient management planning
  • Among other several methods

What are CO₂ and other gases?

Have you ever wondered what carbon dioxide is and also where it comes from? Well, it’s simply defined as a greenhouse gas that doesn’t harm when in smaller quantities or low levels and also is naturally produced.

Carbon dioxide and other gases emissions in agriculture

When produced at higher levels, it can alter productivity rates and even sleep. Apart from that, this gas is always generated indoors through the air that we inhale, and also its levels concentrate indoors with much less ventilation.

Why is CO₂ important?

Carbon dioxide is built by one section of carbon and the other two sections of oxygen. This gas has proved to be on the list of the essential gasses on the planet since it is used by plants to generate carbohydrates through a process that is known as photosynthesis.

  Some reasons why you should choose precision farming

Humans and animals highly depend on plants for food making photosynthesis crucial for the survival of any form of life on earth.

Where does CO₂ come from?

Indoor carbon dioxide levels mainly result from a combination of outdoor CO₂ – indoor breathing and also the general ventilation rate of the building. Whenever buildings and even homes continue to be of high energy and also airtight, the lesser fresh air is found in the building.
Where does CO₂ come from?

Several or nearly all of the ventilation systems that are built and used these days mainly recycle air to reduce the energy used, by pushing the contaminated air around as opposed to generating new air. Through this, high levels of CO₂ are produced and also low-quality indoor air.

CO₂ as a cause of climate change

You must have heard about CO₂ emissions in relation to global warming. As the CO₂ levels increase in the air through the burning of fossil fuels, it all results in a warming effect that has higher chances of altering the earth’s climate.

Climate change also destabilizes the Earth’s temperature equilibrium and has far-reaching effects on humans and also on the environment.

A difference is attained between direct and indirect impacts of climate change. Sharp points in the climate system with unpredictable and also irreversible results can then be felt. It is not scientifically possible to give each weather event to the current change in the climate.

However, it is possible to statistically prove that global warming will heighten the chances of extreme weather events. Some of the direct impacts of man-made climate change are not limited to:

  • Increase in maximum temperatures
  • Increase of minimum temperatures
  • Increased ocean temperatures
  • Thawing permafrost
  • An increase in heavy precipitation (heavy rain and even hails)
  • Glacier recession and retreat
  • Decrease in Arctic sea ice and snow cover
  • Increase in aridity and drought
  • Increase in the proportion of extreme tropical cyclones

Some of the indirect impacts of climate change that directly affect us and even our environment are not limited to:

  • Increased hunger and water problems more so in developing countries across the globe
  • The threat of impending problems due to floods and even forest fires
  • Health risks and problems increase in frequency and also intensity of heat becomes excess
  • Economic implications of countering the secondary damage that is due to the climate change
  • Increased spread of pests and even pathogens
  • Loss of biodiversity due to reduced adaptability and also adaptability speed of both flora and fauna
  • Ocean acidification that results from increased HCO3 concentrations in the water as an impact of increased CO₂ concentrations
  • The demands of adaptation in all areas such as forestry, tourism, agriculture, and many others several changes that happen due to alterations in the ocean, ice sheets, and even global sea level – in relation to the past and future greenhouse gas emissions in centuries all the way to millennia are irreversible.
  What are the steps of the carbon cycle?

How is it formed in agriculture?

Moving and changing from one form to another in all kinds of farming systems, greenhouse gasses are absorbed and also released at different intervals and also in a different range of levels.
Apart from earlier discussed ways, carbon dioxide can also be released via ways such as:

  • Decaying plants
  • Activities involving insects and microbial found in the soils
  • Burning fossil fuels

Carbon dioxide is also taken in by plants through photosynthesis and also kept in vegetation and in the soils in the form of carbon. Carbon dioxide also travels across the atmosphere and landscape in ways such as:

  • Carbon dioxide escapes from the soil via plant decay, insects, and also microbial activity in the soil.
  • Carbon dioxide is derived from the blazing fossil fuels to generate heat, electricity, and also fuel.
  • Carbon dioxide is also produced by both animals and plants via respiration.
  • Carbon dioxide is taken in by trees, grazing fields, and also plants via photosynthesis and converted to other different complicated carbon compounds and oxygen.
  • Animals consume carbon by eating plants.
  • Carbon found in organic residues such as dead roots, branches, manure, and urine is taken into the soil.

What to do to reduce carbon dioxide emissions?

Every day, changes in the climate can be felt with much ease by mostly the farmers, and sadly, few of them know of the ways that can be used to prevent or counter this catastrophic problem. Fortunately, there is one hidden solution that is used to lower the levels of greenhouse gasses held in the air- agriculture.

Lowering tillage, adjusting crop rotations , growing more cover crops, and also integrating livestock with crop production systems are some of the ways that have proven to lower and even hold more carbon that is generated by other industries.

The held carbon is later converted into plant material or even soil organic matter that heightens the average soil health and also adjusts the capability to produce food that is essential in the future.

Apart from the above-described benefits, these inputs are also known to lower the costs too. Embracing the solutions is the best way to go and it is one of the major reasons why you may have been wondering why several farmers across the globe have always insisted on the use of ancient agricultural trends.

  Use of biodiversity in modern agriculture

There are also other several practical methods to avoid the losses of greenhouse gasses that always relate to improved farm productivity. Many of them involve creating carbon farming and also carbon offset.

Frequently Asked Questions

1. How agriculture companies can reduce their carbon footprint?

Agriculture companies can reduce their carbon footprint by implementing several strategies. Firstly, they can adopt precision agriculture techniques to optimize fertilizer and pesticide usage, minimizing emissions.

Secondly, transitioning to sustainable farming practices like organic farming or conservation tillage can reduce energy consumption and emissions. Additionally, investing in renewable energy sources, such as solar or wind power, can help offset emissions from farming operations.

Lastly, promoting efficient water management and exploring innovative technologies can further enhance sustainability and reduce carbon footprint in agriculture companies.

2. How is nitrous oxide produced in agriculture?

Nitrous oxide (N2O) is produced in agriculture primarily through two processes. The first is the microbial breakdown of nitrogen-based fertilizers, such as synthetic fertilizers or animal manure, in the soil. This process is known as nitrification and denitrification.

The second process occurs when livestock, particularly ruminant animals like cows, digest food and release nitrogen-rich waste, which undergoes similar microbial transformations in soil or manure storage systems.

These processes contribute to the production and release of nitrous oxide, a potent greenhouse gas with a significant impact on climate change.

3. Where does carbon come from?

Carbon originates from various sources. It is naturally present in the Earth’s atmosphere as carbon dioxide (CO2). Carbon is also found in living organisms, including plants, animals, and humans, as it is a fundamental component of organic molecules.

Additionally, carbon is stored in fossil fuels like coal, oil, and natural gas, which formed over millions of years from the remains of ancient plants and organisms.

Through natural processes and human activities, carbon moves between the atmosphere, living organisms, and the Earth’s geosphere, creating the carbon cycle.

4. How to show that carbon dioxide is necessary for photosynthesis?

To demonstrate the necessity of carbon dioxide for photosynthesis, you can conduct a simple experiment. Take two identical potted plants and place them in separate environments.

In one environment, provide normal air with carbon dioxide, while in the other, exclude carbon dioxide. After a period of time, observe the plants’ growth.

The plant with access to carbon dioxide will likely exhibit healthier growth, demonstrating that carbon dioxide is essential for photosynthesis, the process by which plants convert light energy into chemical energy using carbon dioxide and water.
