Carbon sequestration has been the subject of several studies over the last few decades, some of which are still ongoing to assess its effectiveness and impact on the reduction of Carbon Dioxide emissions. Today we are going to answer the following questions: what is Carbon Sequestration? What are the benefits of Carbon Sequestration? How can drones help with Carbon Sequestration? Keep reading and find out how carbon sequestration and our drones can help you to #ONEUPYOURBUSINESS.

HOW IS CARBON DIOXIDE PRODUCED?

Carbon Dioxide is the most common greenhouse gas released to the atmosphere and is made in two main ways:

  • By animals, which exhale Carbon Dioxide as result of the respiration process
  • By human activities, mainly energy production and driving internal combustion cars

WHAT IS CARBON SEQUESTRATION?

Carbon Sequestration is a method of reducing the amount of atmospheric Carbon Dioxide by capturing it and storing it.

There are two main types of Carbon Sequestration:

  • Geological
  • Biological

WHAT IS GEOLOGICAL CARBON SEQUESTRATION?

Geological Carbon Sequestration is a process in which the Carbon Dioxide is separated from other gases that are released to the atmosphere, compressed into a liquid and then injected into porous rock surfaces like sedimentary rocks, the deep ocean or even empty oil reservoirs.

WHAT IS BIOLOGICAL CARBON SEQUESTRATION?

Biological Carbon Sequestration is the process of storing atmospheric Carbon Dioxide by promoting vegetation growth.

HOW ARE CARBON SEQUESTRATION AND ORGANIC FARMING LINK TOGETHER? SOIL ORGANIC MATTER

They key element that links Carbon Sequestration and Organic Farming is soil organic matter.

Soil organic matter consists of plants and animal residue that are decomposed by a range of micro-organisms. The impact on soil fertility is crucial, as this decomposition process releases nutrients back into the soil.

There are several ways of increasing soil organic matter:

  • Cultivating perennial crops like grass for pasture or legumes
  • Use of animal manure, crop residues or composts

By promoting the soil’s health, the number of micro-organisms increase, which in turn accelerate the decomposition rate and therefore the number of nutrients released into the soil.

Increasing soil organic matter has a plethora of benefits for organic farming:

  • Healthier crops
  • Higher yields and therefore bigger profits
  • The soil becomes more resistant to erosion
  • Better moisture retention
  • Reduced costs by using less fertiliser
  • Increased Carbon Sequestration

The most conservative calculations estimate that by every 0.1% increase on soil organic matter per hectare there would be almost 9 tonnes of additional sequestered Carbon Dioxide.

HOW CAN DRONES HELP WITH CARBON SEQUESTRATION?

There are several key metrics to monitor when you are going through Carbon Sequestration:

  • Soil type
  • Soil temperature
  • Soil pH
  • Micro-organism analysis
  • Soil moisture analysis

Our fleet of multi-rotor and fixed-wing drones can accurately assess the progress and effectiveness of your Carbon Sequestration strategy by producing two different types of comprehensive and detailed thermal reports of the soil.

When you are effectively sequestering Carbon Dioxide, your soil will have a very consistent and uniform temperature across the whole area. This temperature will also be higher than soils that aren’t retaining Carbon Dioxide.

With the correct Carbon Sequestration strategy the difference between the lowest and highest temperature of your soil will be minimal, and our thermal camera will produce a very uniform image. Take a look at the two images below, the one that contains more blue was taken in a field that did not sequester Carbon Dioxide, whilst the image that is uniform was taken in a field with an effective Carbon Sequestration strategy.
