One of the most frustrating things in the world of gardening is struggling with poor quality soil right?
Luckily there are some quick fixes that can dramatically change the quality of your soil.
The good news is:
In this post I am going to show you how you can quickly and easily transform your garden!
Let me say this straight:
Good soil is the most important factor for healthy plant development. This is because plants get almost all the nutrients and moisture directly from the soil.
In addition, soil also provides plants with a stable base to anchor their roots. Growing plants in bad soil will therefore always lead to disappointing results and is why so many people want to know how to improve garden soil.
Some qualities of bad garden soil include:
Low nutrient content that causes stunted growth and discoloration of leaves.
Poor water drainage causing the soil to dry up too quickly or retain too much water.
Soil that is compacted too tightly or is too loose due to a disproportionate mixture of clay, loam, sand and manure. This hinders root development and causes poor aeration and drainage.
Extreme acidity or alkalinity.
Above – If you don’t have time to read all of this post the video above gives you a quick look at how you can improve your soil
How To Improve Garden Soil – Where To Start
Testing The Soil Quality In Your Garden
Garden soil preparation isn’t something to worry about, in fact the most common soil problems can be easily identified after conducting one, or several, separate soil tests.
Each of these tests will check the soil for a specific quality that is crucial for healthy plant development.
Soil Consistency Test
This test is done to check if the soil has the right balance of sand, clay and loam.
Stick with me here and I’ll show you how easy it is:
Collect some soil from your garden and add a little water to moisten it.
Place the moistened soil sample on your palm and squeeze it firmly with your fingers.
Hold the sample for a few seconds before opening your hand.
Here’s the kicker:
Good soil will create a solid lump that crumbles when you apply pressure to it.
If the soil forms a hard and sticky lump which simply deforms instead of crumbling when pressure is applied, it contains too much clay.
If the soil sample crumbles immediately you loosen your grip, it contains too much sand.
This will test the soil’s ability to hold moisture and efficiently drain excess water.
You want to see how it works right?
Dig a hole in the ground about a foot deep and six inches wide (The soil you dig out from this hole will be usedlater, so don’t discard it yet!).
Pour water into the hole and let it seep into the soil. Once all the water has been drained, fill the hole with water once more.
Observe how long it will take for the water to drain into the soil after you fill the hole for the second time.
The water should drain completely after around three or four hours.
If it drains in less than three hours, the soil is too porous. If it takes more than four hours for the water to drain then the soil has poor drainage.
Earthworms help to ensure proper soil aeration and drainage through the tiny channels they create as they bore through the soil.
A good worm population also indicates that the soil contains enough organic material.
Ok so here’s how it goes:
For this test, you can use the soil you dug up from the ground while conducting the drainage test above. Spread this soil on a polythene sheet and count any visible worms.
The secret is:
Good soil should have about 8 to 15 worms per cubic foot of soil.
If you find anything less than eight earthworms per square foot of soil, then the worm population in your garden is too small.
A pH test will give you an accurate measurement of the acidity or alkalinity of your soil. Plants generally grow best on soil that is slightly acidic as opposed to alkaline soil.
To do this test you will need a litmus paper kit. This kit can be purchased from any department store.
First of all:
Collect a fistful of soil from any random spot in your garden and place it in a cup. Ensure that the soil does not occupy more than a quarter of the cup’s volume.
Add some distilled water to the cup up to the halfway mark and stir continuously until the soil mixes with the water to form a thick paste. Let the mixture sit for 30 minutes.
The soil will gradually settle at the bottom of the cup, leaving a layer of dirty water on top.
Carefully pour out a little water from the cup into another empty cup and place a piece of litmus paper in it. The litmus paper will turn into a different color to indicate the pH level of the soil sample.
Use the pH chart that came with the litmus kit to match the color of this litmus paper to its corresponding pH value. The optimum pH for garden soil should range between 5 and 7.
A pH value lower than 5 will mean that the soil is too acidic and a value higher than 7 will mean that the soil is too alkaline to support healthy plant development.
Improving Soil Quality
One of the best qualities of soil is that no matter how poor it is, there is always something that can be done to improve it.
And the best part?
There are some simple techniques that you can use to do away with the most common soil problems:
Most garden soils contain of a mixture of loam, clay and sand in their composition.
Want to know a secret?
Crops generally grow best on soil that contains a high percentage of loam.
If a soil consistency test shows that your garden soil has too much clay or sand, you can add lots of organic material such as compost or manure to improve its texture.
So what’s the answer?
Spreading a 3 to 6-inch layer of compost over your garden will improve the texture of soil that contains too much sand or clay and also improve the soil’s fertility.
Poor soil drainage occurs in soils that have a relatively high percentage of clay.
The fine nature of clay particles causes soil to compact very easily, making it hard for water to drain into the ground.
The solution is:
You should first spread a 3-inch layer of coarse sand over your garden. Use a garden hoe to dig up the top layer of the soil to mix it with the coarse sand.
This will add some space between the soil particles and make it more porous. You can then spread a 2-inch layer of compost over the soil to add nutrients and improve its texture.
The ideal pH value for garden soil should be between 5 and 7. When the soil has a pH of between 5 and 7, plants will absorb nutrients easily.
The trick is:
If pH tests show that your soil is too acidic, you can sprinkle some lime on your garden to make it more alkaline. If your soil is too alkaline, adding sulfur will help to balance out its pH level.
Improving Soil Fertility
Crops that have been grown on infertile soil will start to show symptoms of nutrient-deficiency. Such symptoms include the yellowing of leaves and stunted growth. Don’t worry though, this is easily rectified.
Allow me to explain:
You can make your garden more fertile by adding organic material into the soil. The best organic matter for your garden are materials like compost or manure – they contain all the nutrients that plants need to grow.
Organic materials are also safer for the environment compared to chemical fertilizers.
Increasing Worm Population In The Soil
Earthworms help to break down organic matter in the soil to speed up the release of vital nutrients.
Furthermore, they improve the soil’s aeration and drainage by creating tiny channels in the ground as they move.
The bottom line:
Since earthworms feed on organic matter, you can increase their population by simply adding more compost into the soil.
