Soil regeneration is simply the process of improving the quality of your soil by adding organic matter, which helps to improve drainage, water retention, and nutrition for your plants. Soil regeneration farming involves returning nutrients and organic matter to the soil to restore the soil’s fertility and productivity. This can be done by using cover crops, green manures, and composts. These are all plants that are grown specifically for their ability to increase the fertility of the soil they grow in. Cover crops are planted in between harvests of the main crop, such as wheat or corn, to protect against erosion and shade out weeds. Green manures and composts are used to restore nutrients into the soil after a harvest has been taken from it.

Soil regeneration may be done by several means, including:

Restoring a degraded area to its natural state.
Introducing and promoting native species.
Using organic matter to improve the soil’s physical properties and fertility.
Using cover crops to increase organic matter and manage moisture.
Soil regeneration is a long and slow process, but the rewards are great. Your plants will flourish, you’ll save money on fertilizers and pesticides, and you can even sell your excess produce for more money.

What is soil regeneration farming and why is it important?

Soil regeneration farming is a way of farming that focuses on building up the soil and improving its quality, intending to improve plant growth and crop yields. Soil regeneration is an important part of sustainable agriculture. It involves practices that build soil organic matter, reduce erosion, increase water retention and retention of nutrients, improve soil structure and create more diverse plant communities in your field.  The main goal of this type of farming is to increase the soil’s ability to hold water and nutrients. This can be done in many ways, including:

  1. Improving the structure of the soil by adding compost or other organic matter.
  2. Adding cover crops to protect the soil from erosion during fallow periods.
  3. Planting diverse crop rotations that include legumes and grasses.
  4. Soil regeneration farming is important because it results in better crop yields. Healthy soils can retain water better, which improves moisture conditions for plants in dry areas or during droughts.
  5. They also have higher concentrations of nutrients that plants need to grow well.

It also helps in improving the water quality in lakes and streams. Healthy soils contain fewer nutrients like nitrogen and phosphorus that can cause algal blooms in lakes and streams when they wash out into waterways during rainstorms. By improving soil quality, farmers can reduce runoff from their fields during storms so it doesn’t contaminate nearby water bodies with excess nutrients. Soil regeneration is an important way of improving soil quality. It involves returning nutrients and organic matter to the soil to restore the soil’s fertility and productivity.

Causes of soil degradation

Here are some of the causes of soil degradation:

Overgrazing
Overgrazing is the most common cause of soil degradation. It is caused by too many animals grazing in a specific area for an extended period. This leads to a reduction of plant cover and poor plant growth, which in turn results in the loss of organic matter and nutrients from the soil.

Over-use of pesticides and fertilizers
These can cause pollution and harm wildlife. They may also damage the structure of the soil by killing bacteria that help plants grow healthy roots and shoots, which in turn affects crop yields.

Inappropriate irrigation practices
Practices such as flooding fields during rainy seasons or leaving fields dry for extended periods can both damage soils because they disrupt the balance between water infiltration rates (how fast water moves into the ground) and evaporation rates (how fast water evaporates from plants.

Excessive irrigation can also lead to the leaching of nitrogen into groundwater supplies, which may result in eutrophication (excessive nutrient enrichment) of waterways and surface waters.

Over-cultivation
Over-cultivation happens when the soil is tilled excessively. This ends up causing compaction and loss of organic matter.

Poor drainage
This can lead to waterlogging and salinization of soils.

What is the benefit of regenerating soil?

The benefits of regenerating soil include:

Increased productivity
Regenerated soils have more nutrients and minerals than depleted soils. This means that crops can grow better and produce more yields than those grown in depleted soils.

Improved water retention
Soil that has been regenerated will have better water retention capacity than depleted soils because it contains more organic matter which helps retain moisture in the soil.

Reduced fertilizer use
Regenerated soils require less fertilizer for optimum performance compared with depleted ones because they contain all the nutrients needed for plant growth without additional applications.

Soil erosion control
Regenerating soil helps plants grow better because they have more nutrients and water available to them. This allows them to grow bigger and stronger so they don’t have to worry about being blown over by wind or washed away in rainstorms.

Increased crop yields
Regenerated soils have greater water holding capacity than tilled soils and have a higher nutrient content. The latter means that you can grow more food on less land, which reduces the need for fertilizers and other chemicals. Regenerated soil also has a higher pH (a measure of acidity or alkalinity), which means that plants can absorb more nutrients from it. This leads to more nutritious crops, which makes them healthier for people to eat too.

Improved soil health

Regenerative agriculture practices build soil health by enhancing biological activity in soils, increasing microbial populations that improve nutrient cycling, supporting beneficial organisms that protect crops from pests and disease, and increasing carbon sequestration.

How to regenerate soil: 5 core principles

Here are 5 core principles of regenerative farming:

Integrating livestock
Animals are not necessary for regenerative agriculture, but when cattle graze, they return nutrients to the soil in the form of manure, which is a crucial service. By encouraging organic matter, stimulating soil microbial populations, and enhancing nutrient cycling, this approach enhances soil health.

Adding plant diversity
Plants play an active role in seeking nutrients, defending themselves from pests and disease, responding to invasive plants, and stimulating soil microbial activity. When farmers promote plant diversity, they promote an environment in which plants interact, soil microbial activity can be stimulated by plants, and farmers will benefit in several ways. They can reduce input costs because soil microbes can provide more nutrients and more water to plant roots than plants can obtain on their own. In addition to actively seeking nutrition, plants also actively respond to invading species, protect themselves from disease and pests, and promote microbial activity in the soil.

Farmers profit in several ways when they encourage plant diversity because it creates an environment where plants may interact and soil microbial activity can be increased. Because soil bacteria can supply plant roots with more nutrients and water than plants can on their own, they can lower input costs. Farmers should cultivate a variety of warm- and cool-season grasses, warm- and cool-season broadleaves, which cover the main plant kinds that naturally occur in untamed areas, to take into account plant diversity.

How to regenerate soil

Building soil armor
It’s essential to keep your soil covered if you want to create and sustain soil health. More specifically, it preserves soil moisture, boosts organic matter, and enhances soil structure while reducing runoff and soil loss. There are two types of soil armor: passive armor, which consists of agricultural residue left on the ground after harvest, and active armor, which involves cultivating cover crops.

Minimizing soil disturbances
Farmers can reduce soil disturbance by using no-till or strip-till techniques, which will ultimately improve soil health. “Fields managed to utilize no-till farming for numerous years have a higher water retaining capacity,” claims the USDA. This is essential in areas prone to drought since a lack of water can lead to crop failure.

Maintaining continual living plant roots
Farmers may cycle more nutrients by utilizing cover crops and microbes that encourage more strong root systems in all crop kinds.

What can farmers do for soil regeneration?

Below are some of the things farmers do for soil regeneration:

Cover cropping
Regenerative agriculture and soil health both depend on encouraging more continuous plant and root growth in the soil. According to some regenerative agriculture theories, cover crops can fix CO2 from the atmosphere and sequester carbon as organic matter in the soils. They can also feed carbon plant root exudates into the soil, which promotes soil biology, add nutrients to soils, and lessen soil erosion.

Depending on the soil requirements and the region, many crops can be employed. Excellent scavengers of surplus nutrients left in the soil after crop harvesting are cover crops. The extra nutrients can be recycled until needed at the start of the following planting season after being incorporated into their biomass and stored. Additionally, cover crops will aid in reducing agricultural run-off and potential fertilizer leakage into watersheds and groundwater. To reduce the requirement for nitrogen fertilizers the next season, leguminous cover crops can be utilized to fix nitrogen from the atmosphere into the soil.

Cover crops may be sown between rows in some permanent crop systems. Maintaining soil cover prevents potential soil erosion, controls weed growth, and may even provide habitat for pollinators. The use of cover crops is a fundamental strategy that can help to improve soil biology and structure, recycle nutrients, lessen the need for synthetic fertilizers, trap carbon from the atmosphere into soils, and reduce agricultural runoff. This is a crucial tool that may improve your bottom line while also rejuvenating your soils for maximum crop health and output.

Reduced or no-till farming practices
The quantity and variety of soil microorganisms increase when soils are not disturbed, leading to better soil microbiome communities and soil structure. These enhancements assist the environment while also enhancing crop quality, resilience to crop stresses, and eventually production.

Environmentally speaking, these activities enhance soil structure, lessen soil erosion from wind and water, reduce agricultural runoff into watersheds, and support soil carbon sequestration.

According to some regenerative agriculture ideas, growers that embrace reduced or no-till practices may see a variety of improvements on the farm that may boost their financial bottom lines while regenerating their soils for future generations. Less soil crusting, higher soil nutrient retention, availability of crops, increased water penetration and retention, and increased soil organic matter over time are all effects of reduced or no-till techniques. All of these have a significant impact on the resilience of crops to stresses and, ultimately, crop output.

Also, there are ways for growers to cut costs, such as by using water more effectively, requiring less fertilizer, and reducing the need to till the soil. Overall, low or no-till techniques are essential elements of regenerative agriculture that will benefit society in the short and long terms by restoring soils.

Composting
Restoring depleted soils requires creating organic soil. Regenerative agriculture relies heavily on digested biological elements like crop residue, food scraps, and animal manure to increase the organic matter in the soil. These materials contain carbon, which when added to the soil slowly decomposes to create stable organic matter. It takes time for organic materials to become stable.

Composting can hasten the decomposition of these components, resulting in compost products that may be more readily available for use by plants and soil bacteria. Earthworms, nematodes, bacteria, fungi, and other species can all contribute to the composting process. Composts provide fertilizer value to your soils and crops in forms that are available over longer periods than traditional fertilizers, in addition to replenishing carbon/organic matter in soils.

Farmers are often faced with challenges of soil degradation, which can affect their ability to produce crops and other plants. Soil degradation can have an impact on the quality of the soil and its ability to support plant growth. It can also affect the environment as well as human health.
