Before maintaining your clay soil you should do some research about the background of your soil. Mostly soil consists of silt, sand, and clay particles. The particles of clay are very smallest, the size of silt particles is intermediate and the last one sand has the largest particles. 

The size of clay particles is so small that they can attach each other by electrochemical forces. The most important thing about clay soil is that it can absorb important nutrients such as potassium, ammonium, calcium, magnesium, and other beneficial elements but all these nutrients are worthless due to the compaction of the soil. 

But it is very difficult to grow vegetables in clay soil because it is very tough to till and difficult for the delicate roots of your vegetable to penetrate. The clay soil easily becomes waterlogged and sticky. If you are living in such an area where you have to wait for the drying of clay soil then you should think about the improvement of your soil. 

Clay soil is the most finicky type of soil as it requires more attention and care. If you are a beginner then it is not easy for you to deal with it. In such a condition raised bed is an option for you as you can manage the fertility and drainage quality of the soil. Now we discuss some easy ways to transform clay soil into healthy soil.

CORRECTING CLAY SOIL PROBLEMS

Clay soil is full of nutrients but all of these nutrients are bound up in compact soil. That’s why we can’t take advantage of all its nutrients. Oxygen is very important for plants to access nutrients. In compact and dense soil, plants can’t get access to nutrients. 

Aeration is also the cause of the drainage problem. All these problems can result in low yield and your hard work can be lost if you did not give proper attention to the clay soil of your growing area. Mix your existing clay soil with compost fertilizers and other amendments like bone meal and manure which will improve the quality of your soil. 

Organic materials are another option to aerate and increase the fertility of the soil. Organic materials such as straws, garden compost, and chopped leaves help you a lot and give a dramatic improvement in the yield of your garden by supplying all basic nutrients to your soil. In this way, both fertility and aeration will be improved.

We are going to give you some tips and tricks which will help you to take out of this problem. Clay soil is very tricky but if you work properly then no one stops you from getting good yield even growing vegetables in the clay soil. You can improve the quality of soil by following these 6 steps, try to deal with your clay soil according to the tips which are going to explain below.

1- CONTOUR THE LAND

Add contours to your garden, it is necessary because it will help to manage water. As drainage is a big problem of clay soil and contouring prevents your soil from waterlogging. In the low spots of your garden organic matter builds up and high spots dry out faster. 

You should follow the first step of contouring before all other steps. It is important to know that the ideal time of contouring is when your soil is full of moisture. But make sure that your soil is not waterlogged.

On the hot days, due to the high heat of the sun, clay soil can easily become compacted. To overcome the drainage problem by contour is the best solution to this problem.

2- AERATE CLAY SOIL

Aeration is the key to the success of getting higher yield although you are growing plants in the clay soil.  Before adding organic material to your soil you should aerate the soil. 

Air is very important to improve the drainage quality of your soil. If you did not prepare your clay soil then a solid sheet of clay is made underneath the layer of amended soil. There are different tools that you can use for this purpose. Most favorites are broad fork, digging fork, and plug coring aerator. You can use any tool to aerate your soil twice a year. The best time for aeration is:

  1. First, in the fall as it is the time when your growing season ends.
  2. Second, in the spring before planting your favorite veggies.

Keep it in your mind that fall aeration is most important as compared to spring aeration because it counters any act of compaction which occurs during the season. The poking holes should be as deep as you can and in the whole area of your garden. 

3- ADD SOIL AMENDMENTS TO CLAY SOIL

If you add soil amendments following the aeration process then you will see a better result of this act. As rain can wash these amendments into the poking holes ( which you made with the help of tools) and help to make clay soft. For changing the structure of the soil you need a large amount of organic matter. 

Before starting maintaining the clay soil first you should do some research about the background of your soil. Now we will discuss some types of organic matter which help to attract microorganisms to speed the process of soil improvement.

After adding the soil amendment the next step is adding mulch. If you are not planting a cover crop then mulch is very necessary for the improvement of your clay soil. Mulch is an inexpensive way to increase the quality of your soil. 

lt can provide an absorptive surface which will help to suck all the extra water that would log itself in the clay. The best mulching material is shredded leaves, they are easily available from your yard and provide proper feed to your soil. Straw and alfalfa are also appropriate materials for mulching.

TIP

During the rainy season don’t mulch heavily. because in this way your soil can’t breathe properly and it will create fungal issues.  If you are living in a hot and dry climate then you can mulch heavily to protect the soil.

After completing all the steps very carefully,  the last thing which is very important and you have to follow is to avoid walking in the beds, because it can cause compaction all over again and all your hard work will be lost.
