How To Choose The Best Soil Amendments

Types Of Soil Amendments

There are various types of soil modifications, which sometimes puzzle beginners to choose the best one. Animal-based, mineral-based, and plant-based amendments are the main products you can often come across on the market.

The first ones are manufactured to increase beneficial organisms to improve soil structure. With this type of amendment, it would be best to apply untreated animal products at least nine months before harvest and two weeks before planting.

Plus, the second type is available to correct mineral deficiencies. You can apply it several times as it doesn’t break down easily. On the other hand, plant-based amendments can be used to improve soil structure.

Yet, herbicide contamination can lead to lackluster performance and stunted growth. Therefore, it is vital to have herbicide-free amendments.

Types Of Soils

Each type of soil is compatible with different amendments. Clay soil is often used to make ceramics and pottery, so it comes with a high percentage of silt and clay. 

Thanks to the small and clingy particles, clay soil holds water and nutrients well. Yet, it is susceptible to compaction. This way, it curbs nutrients and moisture from reaching the plant roots and prevents the roots from penetrating the soil.

Sandy soil comprises larger and coarser particles, which drain quickly and fail to hold nutrients and moisture effectively. This type of soil appears rough and cannot hold together well. Succulents and cacti can grow best in this soil mix despite these characteristics.

Loam is another common garden soil. It is a good balance of sand, clay, silk, and organic material. Overall, this is the best soil type for gardening, moisture retention, and drainage. Loam will keep in shape even if you squeeze it.

Longevity Of The Amendments

The desired type of amendment will depend on your gardening goals. For instance, if you are looking for a method to improve the soil’s physical properties quickly, the one that decomposes rapidly will be ideal.

Conversely, the one that decomposes slowly will offer a long-lasting improvement to your soil. For a quick and long-lasting improvement, let’s pick a combination of amendments.

Soil Salinity

Some forms of manures and composts are high in salts. Thus, avoid applying those amendments to soils already high in salts or plants sensitive to salts. Maple, bean, onion, strawberry, raspberry, and viburnum are a few.

Ground leaves and sphagnum would work wonders for those landscape plants instead of manures or compost.

Soil pH Level

Soil pH indicates soil fertility and nutrition, which affects the plants’ growth and the availability of minerals and nutrients. This figure will let you know how well a plant can absorb and regulate all materials.

A pH from 6.0 to 7.0 will be ideal for most garden vegetables. At this level, microbial activity is greatest, and plant roots can access most nutrients. Yet, each plant has specific pH range preferences. Therefore, don’t forget to check the level before amending.

How To Use Soil Amendments

For green fingers, using soil amendments should not cause any difficulty. Prepare all the needed equipment and materials, then get your hands dirty. 

Gardening gloves, tiller, or garden shovel are necessary to help you make the job done easily and safely. Besides soil amendments, it would also be better to get some lime, fertilizer, and organic materials. Manure, compost, and peat moss are some recommendations.

To get started, let’s evaluate and check the health of your soil first. You can get help from the nurseries to receive an overview of your soil. The information should include pH, texture, and nutritional composition.

The tests will also recommend which type of amendments to use, the quantities, and how to correct deficiencies. You can also guess the soil quality. 

If the plants are healthy and thriving well, don’t try to fix what’s not broken. On the other hand, it would be best to have a detailed test if your plants grow yellow and look sickly. 

Before adding amendments, it’s time to adjust the soil pH. This is crucial as plants cannot take up nutrients properly if the acid levels are not in their ideal range.

If your soil test shows that the pH is off, you will need to add some lime to raise this level of sulfur to lower it. This should be completed in stages in an existing garden to avoid shocking the plants.

Don’t add more than five pounds of sulfur or lime per 100 square feet. On the contrary, rake the component, dig it into the garden tiller, and add the whole recommended amount for a new garden. 

Proper soil texture can let the roots take up enough air and moisture. Clay-type and dense soils are often too moist, making the roots drown. On the other hand, sandy soil tends to drain too quickly for the plant’s roots to absorb adequate moisture.

The best way to improve the situation is to add organic materials like peat moss and compost. Decaying organic matters allow sandy soils to retain water while making clay ones looser and get enough water and air.

There are five common forms of materials to amend your garden soil. Compost is ideal as you can use kitchen scraps and garden waste. Manure is another suggestion from stables and local farms. Yet, this one is smelly and has too much ammonia.

Peat moss is cheap but can loosen the soil effectively. It is dusty, so you should get it first. You can also work with grass clippings directly into a garden bag so that they can decompose slowly. Make sure that they are free from seeds, pesticides, and herbicides.

After this amending step, don’t forget to add nutrients to garden soils. Synthetic fertilizers are cheaper and work more quickly than an organic one. Yet, they only feed the plants instead of amending the soil.

On the contrary, organic ones release nutrients over time and offer a longer and sustained feeding. No matter which type to choose, make sure that it offers three primary nutrients: potassium, nitrogen, and phosphorus.

Frequently Asked Questions

When To Improve The Soil With Amendments?

Don’t assume that only dry soil will need amendments. Your garden needs frequent care and maintenance with an adequate mixture of minerals, organic materials, and other nutrients.

Fertility and texture contribute to good garden soil. The former combines a soil pH level and essential nutrients, while the latter refers to the soil particles’ size, soil ability to transfer water and air. 

If you have poor soil and need to improve both, you must amend your garden soil. The best time for this practice is when you first establish a garden bed.

Besides, if your plants are growing yellow and look sickly, let’s test your soil and see what it needs. Then, apply the essential components and amendments according to the instructions.

What Are Other Types Of Soil Amendments?

Besides the best soil amendments mentioned above, there is a wide range of handmade soil additives that you can choose from. Using them for your garden may sound weird. Yet, they will surely offer expected benefits for your soil.

If you use untreated and real wood in your fire pit or fireplace, the ashes remaining after the fire can improve the garden soil. However, charcoal ashes are not recommended as they are often treated with lighter fluid and chemicals.

Applying ash from burned organic materials to the top will add potassium and deter pests from the soil. Biochar, charcoal from organic materials, is also perfect for your garden.

It is made by the slow-burning of organic material at low temperatures. The additive helps retain water and nutrients while reducing the required amount of fertilizer and irritation.

Blood and bone meals may sound disturbing, but they are healthy amendments to vegetable gardens. Bone meals are great, thanks to the minerals within bones. Magnesium, calcium, and phosphorus are just a few to name.

Greensand is another great suggestion: marine sediment rich in iron, potassium, and other minerals. It works as a perfect slow-release fertilizer and is ideal for improving clay soil. 

Like greensand, seaweed is an excellent additive to soil whether harvested fresh, composted, or dried. The component provides nutrients and improves texture, aeration, and water retention in your garden.
