How Soil Amendments Can Benefit Your Garden

Soil amendments could help improve one’s landscape. They generally use various types of matter, such as lime and compost. It could also provide multiple benefits to the soil, making it contributory to landscaping.

If you’re looking for more ways to further understand solid amendments, here’s an article for you.


The soil is essential for plants to thrive. If the soil is dry and has poor nutrients, plants would typically wither or die. If the soil is healthy, it could provide all the necessities for a plant to grow, bear flowers and fruits such as growing pineapples or bananas, or even offer shade when developed into a tree.  

If you want to develop your landscape, you may face trouble when your soil has poor quality. Generally, this is caused by pollution and over-farming.

There are other ways that affect overfertilization and flooding as these leach out the soil’s nutrients, leading to poor soil quality. When this happens, plants become affected.

4 Benefits of Soil Amendments

In most cases, they fail to bear trees. Trees are more likely to be uprooted when adverse weather affects them. Crops may still grow but won’t thrive. To regain the lost quality of soil, many farmers apply various methods.

One of these is the application of soil amendments. Here are 4 benefits of soil amendments to your garden. 

1. Soil Amendments Help In Plant Growth 

Garden soil amendments can improve the garden soil, especially with organic matter. This way, garden soil gains more nutrients that plants need to grow properly. 

If your garden soil is compact, hard, and clayey, you may consider adding soil amendments to make it more suitable for plants. You may use inexpensive organic matter for this purpose.

Here’s a list of common organic waste that you could use for organic soil amendments: 

  • Manure: It should be composted first before application and appropriately mixed with soil to prevent the burning of plants because of its ammonia deposits 
  • Compost: It’s made of various biodegradable waste, including kitchen scraps, dried leaves, and humus. (Here's our review on the best compost tumbler for 2021)
  • Peat Moss: This needs to be wet before application, ideal for loosening compact soil 
  • Cover Crops: Legumes grown to add nitrogen and loosen the hard soil 
  • Lime: It adds acidity to the soil and should also be mixed to avoid burning the plants
  • Sand: Helps in drainage and in aeration and has a low capacity for holding water 
  • Potash: A salt-based mineral that provides potassium

Each soil has its own needs, so gardeners must assess any soil amendment. Suppose you’re in Kansas City and other nearby cities and still undecided what to apply in your soil.

In that case, you may contact stores that offer organic recycling for different compost-amended products.

2. Soil Amendments Improve Stability For Plants 

Benefits of Soil Amendments

Since soil amendments make the soil porous and permeable, the ground becomes less compact. Because of this, the rapid exchange of carbon dioxide and oxygen—the so-called aeration—takes place.

In the same manner, roots could freely move up to their desired depths, improving the stability of the plants. Furthermore, with better root and pore spaces, water would have better storage and flow.

This way, the nutrients stay longer in the soil and become well-disseminated. This state helps in the thriving of the plants, improving the garden and landscape.

3. Porous And Permeable Soil Improves Landscaping 

In layman’s terms, applying the best soil amendments make the soil more ‘breathable’ for the roots. In this scenario, the dirt loosens because of the presence of organic matter.

Typically, it replaces rocks and sediments that are harder to get through for the roots. With absorbent and porous soil, landscapers could easily plant and transplant flowers and shrubs.

In addition, because of these attributes, the plants in the yard are likely to be healthy.  

4. Adjusts The Soil pH 

Soil Amendments Adjusts The Soil pH

Soil pH refers to the level of alkalinity and acidity of the soil. It’s vital in landscaping as most plants don’t grow well in soil with high alkaline and acid levels. Soil amendments solve this issue.

If you’re planning to use solid amendments for adjusting acidity and alkaline levels, be reminded that you should test the soil first. Soil pH will serve as the basis for whether you’ll need sulfur or lime to correct the soil pH level.

Furthermore, be reminded that if your garden has fully grown plants, you’d need to apply the amendments in installments. Applying in volume may give more harm than benefits to your plants. 

Generally, if your garden is new, you may use more than 5 pounds of sulfur or lime. You just need to mix the amendments and the soil properly with a shovel for better distribution of the organic matter.

For best soil acidity and alkaline levels, you may conduct a soil test every two years and make the proper amendments accordingly. 

What To Consider In Choosing Soil Amendment 

In choosing the type of soil amendment that you’d use; you need to think of the soil’s current condition. Is the soil dry? Are there organisms, such as maggots, present in the soil? Is it compact? Do a lot of plants grow there?

Furthermore, here are some of the points to consider to make the most of the soil: 

  • soil texture 
  • types of plants growing in the garden 
  • acidity and alkaline levels of soil 
  • type and appearance of soil 
  • age of plants

Soil Amendments In A Nutshell 

Soil amendments provide a lot of benefits to one’s garden or landscape. They could make soil improve its quality, make the plants more stable, and adjust the soil’s acidity and alkaline levels.

Since soil amendments have various types, gardeners would choose among them for specific purposes, such as making the soil more porous or correcting its pH level.

While there are ready-made amendments, mixing up various elements, such as compost, peat moss, and manure could be an excellent choice for amending the soil.  

If you want to enhance your landscape, you may first consider choosing the appropriate soil amendment. Will you be using manure-based soil? Or will you add more potassium with potash?

Whichever your situation is, think about the points you’ve gained in this article. Look at the red flags—the materials which may burn the plants or make the soils more acidic.

Either way, your landscape will have the benefits it deserves as long as the suitable soil amendments are applied.
