Garden soil amendments are materials that are added to garden soil to improve its quality. There are many
different types of amendments, and each one has its own unique benefits.
Some of the best amendments you can make to your garden are compost, lime, peat moss and blood meal. When adding garden soil amendments to your garden, it is important to do so in moderation. Too many amendments can have a negative effect on soil quality. In addition, certain types of amendments may need to be mixed with other materials before they are added. For example, grass clippings must first be allowed to decompose into compost .
One of the most important amendments is compost. Compost is made from decomposed organic matter,
such as leaves, grass clippings, and vegetable scraps. It helps improve soil structure, drainage, and fertility. Find out how much compost you’ll need for your garden here.
Another important amendment is manure. Manure is made from the waste products of animals, such as urine and feces. It helps improve soil fertility and moisture retention.
A third important amendment is lime. Lime is a mineral that helps balance the pH level of soil. It also helps improve soil structure and drainage. Read our Best pH for Garden Soil article to find out if your garden needs lime.
There are many other types of amendments, including rock phosphate, peat moss , and blood meal.
Garden soil amendments help improve the health of your plants by improving the structure and fertility of
your garden’s soil. Compost and manure provide organic matter that improves soil texture and drainage; lime helps balance pH levels; rock phosphate increases nutrient availability; and peat moss retains moisture better. We cover lime more in our Should I Put Lime in my Garden post.
Some types of garden soil amendments, such as grass clippings and manure, require decomposition before they can be added to the garden.
How do I make good garden soil:
To make your soil act more like soil than sand, you can add compost or manure. Use about three inches of
compost every year and you’ll be amazed at the difference it will make in your garden plants.
Greenhouse gases: Manure is helpful in keeping plants healthy because it contains nutrients. However, if too much is used on plants, the manure can increase greenhouse gas emissions since it is high in nitrates.
Grass clippings: Grass clippings contain high amounts of nitrogen, so after they have decomposed a couple times as a part of a mulch pile, they are a great addition to a compost pile. They also contain other nutrients such as potassium and phosphorus so don’t throw them away!
Soil pH levels: Because lime contains calcium and magnesium, it adjusts the pH of the soil. If your plants
are not thriving in your current soil climate, you may need to increase its alkaline level by adding more lime. Not sure if your soil is alkaline or acidic? Find out how to determine this in our How Do I Test My Soil post.
Building up your soil: When you add compost to the soil, you’re actually building up the quality of it. In a
way you can think of it as adding fertilizer without actually adding something that might burn your plants.
Volcanic lava: Volcanic lava is used in gardens because of its nutrient content and ability to help lower pH
levels in the soil. It contains large amounts of calcium that will help soils retain water better than other
substances like sand or gravel.
Additives for your garden soil: Have you ever noticed how many different substances are sold for use in
garden soils? These additives include things like sulfur, ferrous sulfate, magnesium sulfate, Epsom salts,
limestone (calcium carbonate), ammonia sulfate, and blood meal.
Each of these substances performs a particular function in the garden, such as helping to retain soil moisture, adding nutrients to the soil, or countering the effects of high pH levels. When you are choosing an additive to use in your garden, it is important to read the label and make sure that it is compatible with the plants you are growing. For example, sulfur should not be used on alkaline soils because it will make the problem worse.
Adding amendments to your soil can have a huge impact on the health of your plants. Compost, manure, and lime are all essential amendments that help improve soil texture, drainage, fertility, and pH levels. There many other types of amendments available, each with its own unique set of benefits. By understanding the role these amendments play in the garden, you can make sure your plants get the best possible start in life.
When adding garden soil amendments to your garden, it is important to do so in moderation. Too many
amendments can have a negative effect on soil quality. In addition, certain types of amendments may need to be mixed with other materials before they are added.
Top soil vs Garden soil:
Topsoil is the top layer of soil that contains humus, minerals and nutrients. It can be used in farming or
gardening to improve its quality for growing crops. Garden soil on the other hand is used for flowers,
vegetables, trees and shrubs where topsoil is not appropriate for use.
FAQs:
What are topsoils? Topsoils are the uppermost layers of earth’s land surface that contain decomposed organic material like roots or animal droppings mixed with mineral particles such as sand gravel and clay left behind after glaciers retreat. What are some differences between topsoil and garden soil? Because they both come from different places (one below ground, one near ground level) topsoil and garden soil differ slightly in their chemical and physical properties. Topsoil is composed mainly of sand, silt and clay while garden soil includes organic matter such as decomposed plant material.
Generally speaking, the best garden soil is made up of 1/3 sand, 1/3 loam (dirt comprised of silt or clay plus
organic matter), and 1/3 peat moss or composted leaves. Why does adding topsoil to my garden help?
Topsoil tends to be rich in nutrients because it sits above the subsoil where most plants’ roots cannot reach thus it has not been depleted by growing plants. It also tends to have more organic matter than subsoils which helps retain moisture.
Garden soil refers to soil used to grow flowers, vegetables, trees and shrubs. Garden soil includes organic
matter such as decomposed plant material and is rich in nutrients. It must be able to drain water well and
retain moisture while having just the right amount of acidity for growing most plants.
