Can Dirt Save The Earth? Unveiling the Power of Soil

Is dirt the unsung hero in our fight against climate change? Absolutely, and at Savewhere.net, we’re committed to showing you how simple changes in land management and farming can make a huge difference to climate change, carbon sequestration and improving financial well-being. Read on to learn all the tips and tricks!

1. Understanding the Critical Role of Soil in Combating Climate Change

Soil plays a far more critical role in mitigating climate change than many realize. It’s not just dirt, it’s a dynamic ecosystem with the capacity to store vast amounts of carbon. So how much Carbon Dioxide is stored in the ground?

The soil stores three times more carbon than the entire atmosphere. It’s the Earth’s largest terrestrial carbon sink, offering a vast repository with immense, untapped capacity. Since the beginning of agriculture, food production has removed approximately half, or 133 gigatons, of the carbon once stored in agricultural soil. Restoring this carbon stockpile would sequester the equivalent of almost one-fifth of atmospheric carbon, bringing greenhouse gas concentrations nearly to pre–industrial revolution levels and making soil less vulnerable to erosion.

Think of soil as a giant sponge that can soak up carbon dioxide from the atmosphere through a process called carbon sequestration. Plants absorb CO2 during photosynthesis, and when they decompose, that carbon gets stored in the soil. Healthy soil teems with life, including microbes that help break down organic matter and further lock carbon away.

1.1. The Dust Bowl: A Stark Reminder of Soil Degradation

The American Dust Bowl of the 1930s serves as a harrowing example of what happens when we mistreat our soil. Decades of unsustainable farming practices stripped the Great Plains of their fertile topsoil, leaving the land vulnerable to drought and wind erosion. Ravaging winds lifted plumes of soil from the land and left in their wake air choked with dust and a barren landscape. Thousands died of starvation or lung disease; others migrated west in search of food, jobs and clean air. This environmental disaster had devastating consequences, highlighting the importance of soil conservation.

The lessons learned from the Dust Bowl are more relevant than ever. Today, we face the potential for even more extreme soil erosion, intensified by the effects of climate change. Understanding the causes and consequences of the Dust Bowl can help us prevent similar disasters in the future.

1.2. The Dual Threat: Climate Change and Soil Erosion

Climate change is exacerbating the problem of soil erosion. Changes in rainfall patterns, including more frequent and intense storms, are washing away topsoil at an alarming rate. The areas that are the most affected are Iowa, New Mexico and Nevada. A 2018 inventory from the U.S. Department of Agriculture reports that the U.S. loses soil on average 10 times faster than it is generated. This combination of climate change and soil erosion poses a serious threat to our food supply and the health of the planet.

We need to act now to protect our soil and mitigate the effects of climate change. Farmers can be key partners in this effort by adopting sustainable farming practices that promote soil health and carbon sequestration.

2. What Farming Practices Can Help Save the Earth?

Fortunately, there are many farming practices that can help reverse soil degradation and mitigate climate change. These practices focus on increasing the amount of carbon stored in the soil, improving soil health, and reducing erosion. So what practices can farmers use to accomplish this?

Farmers can incorporate more carbon into soil using readily available practices. Photosynthetic carbon fixation removes carbon dioxide from the air, anchoring it in plant material that can be sequestered in soil. This process reduces atmospheric greenhouse gases and reduces soil erosion by enriching soil with carbon that feeds hungry microbes that produce sticky substances, which in turn bind soil particles into clumps that are less vulnerable to movement by wind and water. These practices include:

No-Till Farming: Reduces erosion by minimizing soil disturbance.
Cover Cropping: Protects soil from erosion and adds organic matter.
Crop Rotation: Improves soil health and reduces pest problems.
Managed Grazing: Enhances pasture health and carbon sequestration.

2.1. No-Till Farming: Minimizing Soil Disturbance

Traditional plowing disrupts the soil structure, leading to erosion and the release of stored carbon into the atmosphere. No-till farming, also known as conservation tillage, eliminates or minimizes plowing, leaving crop residues on the soil surface.

This practice has numerous benefits:

Reduced Erosion: Crop residues protect the soil from wind and water erosion.
Improved Water Infiltration: Leaving the soil undisturbed allows water to penetrate more easily, reducing runoff and increasing water availability for plants.
Increased Soil Carbon: No-till farming helps build up organic matter in the soil, leading to increased carbon sequestration.
Lower Input Costs: By reducing the need for plowing and other soil preparation activities, farmers can save on fuel, labor, and equipment costs.

2.2. Cover Cropping: Protecting and Enriching the Soil

Cover crops are plants grown specifically to protect and improve the soil between cash crops. They are typically planted in the fall after harvest and terminated in the spring before planting the next cash crop.

Cover crops offer a wide range of benefits:

Erosion Control: Cover crops provide a protective barrier against wind and water erosion, especially during the fall and winter months when the soil is most vulnerable.
Soil Health Improvement: Cover crops add organic matter to the soil, improving its structure, water-holding capacity, and nutrient availability.
Weed Suppression: Cover crops can outcompete weeds, reducing the need for herbicides.
Nutrient Cycling: Some cover crops, such as legumes, can fix nitrogen from the atmosphere, reducing the need for synthetic fertilizers.

2.3. Crop Rotation: Diversifying for Soil Health

Crop rotation involves planting different crops in a planned sequence over time. This practice can improve soil health, reduce pest problems, and increase yields.

Here’s how crop rotation works:

Nutrient Management: Different crops have different nutrient requirements. By rotating crops, farmers can balance nutrient levels in the soil and reduce the need for synthetic fertilizers.
Pest and Disease Control: Rotating crops can disrupt the life cycles of pests and diseases, reducing their impact on yields.
Soil Structure Improvement: Different crops have different root systems. Rotating crops can improve soil structure by creating a more diverse network of roots.
Weed Control: Rotating crops can help suppress weeds by disrupting their growth cycles.

2.4. Managed Grazing: Enhancing Pasture Health and Carbon Sequestration

Managed grazing, also known as rotational grazing or intensive grazing, involves moving livestock frequently between pastures. This practice can improve pasture health, increase forage production, and enhance carbon sequestration.

Here’s how managed grazing works:

Improved Pasture Health: By moving livestock frequently, farmers can prevent overgrazing and allow plants to recover fully. This leads to healthier pastures with more diverse plant species.
Increased Forage Production: Healthy pastures produce more forage, which means more feed for livestock.
Enhanced Carbon Sequestration: Managed grazing can increase carbon sequestration by promoting plant growth and reducing soil disturbance.
Improved Water Quality: Healthy pastures filter water more effectively, reducing runoff and improving water quality.

3. Government Policies and Incentives

Government policies and incentives play a crucial role in encouraging farmers to adopt sustainable farming practices. By providing financial assistance, technical support, and regulatory frameworks, governments can help farmers overcome the barriers to adopting these practices. So what kind of Policies are needed?

The Biden administration has the opportunity to avert both crises through domestic policy for U.S. agriculture and international policy that would restore U.S. leadership in the battle against climate change. Reducing greenhouse gas emissions is the central feature of most plans to slow the climate emergency at hand. Much less attention has focused on sequestering atmospheric carbon in soil.

Some of the key policies and incentives include:

Crop Insurance Reform: Restructuring crop insurance to reduce premiums on land that is managed in a carbon-friendly manner.
Carbon Sequestration Payments: Providing payments to farmers for sequestering carbon in their soil.
Technical Assistance: Offering technical support to farmers on how to implement sustainable farming practices.
Research and Development: Investing in research and development to improve sustainable farming practices and technologies.

3.1. Crop Insurance Reform: Rewarding Carbon-Friendly Farming

Crop insurance is a vital safety net for farmers, protecting them from financial losses due to crop failures. However, current crop insurance policies often discourage sustainable farming practices.

By restructuring crop insurance to reduce premiums on land that is managed in a carbon-friendly manner, the government can incentivize farmers to adopt these practices. This would reward farmers who are actively working to improve soil health and sequester carbon. The administration could build an alliance of key stakeholders—farmers, food retailers, consumers, Indigenous communities, agribusiness and environmental groups—to design certification and marketing strategies for food sold with a label indicating it had been produced under conditions that sequester carbon.

3.2. Carbon Sequestration Payments: Paying Farmers for Carbon Storage

Carbon sequestration payments provide direct financial incentives to farmers for sequestering carbon in their soil. These payments can help offset the costs of adopting sustainable farming practices and encourage farmers to increase carbon storage.

The label might read “Produced by Carbon Heroes” to recognize the heroism of farmers who make it possible for millions to eat and would now add protecting the planet to their list of contributions. Multinational retailers could demand such practices from their producers as they have already done with other practices friendly to animals and the environment. Current agricultural subsidies could be redirected to pay for both the food and the carbon sequestered during its production.

3.3. Technical Assistance: Supporting Farmers with Expertise

Technical assistance provides farmers with the knowledge and skills they need to implement sustainable farming practices. This can include:

On-Farm Consultations: Providing farmers with personalized advice on how to improve soil health and sequester carbon.
Workshops and Training Programs: Offering workshops and training programs on sustainable farming practices.
Educational Materials: Developing and distributing educational materials on soil health and carbon sequestration.

3.4. Research and Development: Advancing Sustainable Farming

Investing in research and development is essential for advancing sustainable farming practices and technologies. This can include:

Developing new crop varieties that are more efficient at sequestering carbon.
Improving soil testing methods to better measure carbon storage.
Developing new technologies for no-till farming and cover cropping.
Studying the impacts of climate change on soil health and carbon sequestration.

4. The 4 per 1000 Initiative: A Global Effort

Carbon sequestration in agricultural soils was the goal of the “4 per 1000” proposal for food security and climate that was introduced by France during the 2015 Paris climate talks. So what is the 4 per 1000 Initiative?

The proposal contended that increasing the carbon content of soils worldwide by 0.4 percent annually would offset future emissions. Only 29 countries signed the agreement, and the U.S. was not among them. The proposal encompassed all soil on Earth, giving it an aspirational and unattainable nature that put off many potential signatories. So 4 per 1000 should be reformulated to pass a reality test, focusing only on agricultural soil for starters. As President Joe Biden reestablishes U.S. leadership in global climate policy, achieving broad ratification of a proposal to increase soil carbon should be high on his agenda.

The “4 per 1000” initiative aims to increase soil organic carbon by 0.4% per year. While this may seem like a small amount, it could have a significant impact on mitigating climate change and improving food security. The USDA forecast that half of U.S. farms would lose money in 2020. Many farms persist only because a family member provides income from off-farm employment. And financial hardship drives many farms out of business, which is evident in the loss of half of U.S. dairy farms between 2001 and 2019.

Critics of 4 per 1000 argue that the benefits of incorporating carbon into soil would be canceled out by the increased needs for nitrogen fertilizers, which are produced by a fossil-fuel-intensive process. But carbon sequestration can be accompanied by retention of nitrogen in plant material, reducing nitrogen needs of future crops. Moreover, nitrogen needs could be satisfied by biological nitrogen fixation, which is conducted by soil bacteria that need no fossil fuels to make nitrogen fertilizer.

4.1. Addressing the Challenges of Implementation

While the “4 per 1000” initiative has great potential, there are also challenges to its implementation. These challenges include:

Lack of Awareness: Many farmers are not aware of the benefits of soil carbon sequestration.
Financial Constraints: Adopting sustainable farming practices can be costly, especially in the short term.
Technical Barriers: Some farmers may lack the knowledge and skills needed to implement sustainable farming practices.
Policy Gaps: Many countries lack the policies and incentives needed to encourage soil carbon sequestration.

4.2. Overcoming the Barriers to Adoption

To overcome these barriers, it is essential to:

Raise awareness among farmers about the benefits of soil carbon sequestration.
Provide financial assistance to farmers to help them adopt sustainable farming practices.
Offer technical support to farmers on how to implement sustainable farming practices.
Develop and implement policies and incentives that encourage soil carbon sequestration.

By addressing these challenges, we can unlock the full potential of soil carbon sequestration and create a more sustainable future.

5. Individual Actions: How Can You Help?
