Let’s learn how to add potassium to the lawn as it’s an essential micronutrient that prevents diseases and promotes healthy growth.
Your lawn requires a good amount of potassium, depending on the naturally present amount in the soil. If your soil is naturally low in potassium, you will need to supplement it with are potassium-rich fertilizer. To determine how much potassium is in your soil, you will need to conduct a soil test. A soil test showcases what is available, and the nutrient is missing from the soil for more accessible nourishment of your soil.
What Is Potassium?
Potassium, sometimes referred to as potash, is an essential nutrient that your soil requires. It helps your grass take other nutrients and use them. It also helps in building strong cell walls within the grass or plants.
These cell walls are what keep your plants healthy and resilient in times of stress like disease, drought, or severe temperatures.
As your grass grows, potassium lawn fertilizer is needed for that growth. It helps the grass get strong deep roots and causes it to grow faster. A lawn that lacks enough potassium may grow slowly and have shallow roots. This means the grass won’t be able to withstand environmental stress as best as it should.
How To Carry Out A Soil Test
You can carry out the soil test on your own by buying a soil test kit from your gardener’s shop. You can also ask your local extension officer to provide soil containers and information on performing a soil test full stop use a hand trowel to collect soil samples from around your lawn.
Scoop about 10 to 15 samples from your yard at a depth of 3 inches and combine them. Leave the soil samples to dry and package them in containers you are provided with by the extension officer. After that, male the soil samples to the extension officer for testing and wait for results. Results take about 3- 5 days.
How To Tell If Your Lawn Has Enough Potassium
There are a few signs to look out for when you’re trying to decide if your soil has enough potassium. Your grass will show signs of stress that include slow growth, yellowing or being highly susceptible to changes in temperature.
Sometimes just looking at your grass with your physical eyes might not give you the results that you want. So it is advisable to test your soil for potassium deficit before drawing conclusions.
Choosing A Lawn Potassium Fertilizer
Lawn fertilizer has a high ratio of potassium. This fertilizer is rated using three numbers representing the percentage of nitrogen, phosphorous, and potassium they contain. The third number in the sequence presents the concentration of potassium in the fertilizer. In most cases, you can use a fertilizer that has all of the three macronutrients. If your lawn has less than 25 parts per million of potassium, use a fertilizer with a high potassium concentration for yards.
Adding Potassium To Your Lawn
Once you learn your lawn is lacking enough potassium, it’s time to add some.
Apply potassium fertilizer biannually each spring and fall. You will have to add this fertilizer based on the results of the soil test. Your extension officer should advise you what type of potassium fertilizer you should purchase and how much you should apply.
For example, 6 pounds of potassium can go 1,000 sq ft of lawn; this applies to lawns that are between 0 to 25 PPM. Yards that are between 25 to 50 PPM require 4 pounds of fertilizer. Those with 50 to 75 PPM need to pounds of fertilizer, while those that are between 75 and 100 will need 1 lb per 1,000 square feet.
Ensure that you spread your potassium fertilizer evenly all over the lawn. Feed your lawn when the weather is excellent and the soil is dry.
You can also use compost three times a year to increase potassium levels within your soil.
Choosing The Best Potassium For Your Lawn
When choosing the best potassium product for your soil you can use either a long-term or short-term solution. We recommend choosing soluble potassium to help stimulate photosynthesis in plants allowing your grass to remain healthy for long. The main advantage of soluble fertilizers is that they dissolve quickly in water, delivering them into the grass relatively quickly.
Most people opt for fast-acting solutions like potassium sulfate or potassium chloride is there a cheaper option. These two minerals are commonly used for lawn winterizing. Either of these two are a good option but potassium sulphate is a better option as it doesn’t interfere with the good bacteria in the soil.
Before applying any fertilizer, read the label carefully and gather all the information about it as much as possible.
Here are some potential solutions that you can use
- Use Dried Kelp Meal. It has a lot of nutrients that are valuable to the soil and when used it restores potassium levels in your soil
- Use Hardwood Ash. This powder is full of potassium and you can apply straight to the soil or add it to your compost. It is especially significant if you want to increase the pH levels of your soil as well, but before you do so and sure that you monitor your grounds’ acidity.
- Use Sulphate Of Potash Magnesia. This is also known as Sul Po Mag. It is pretty affordable and increases the levels of both magnesium and potassium in the soil.
You can also choose the slow-releasing potassium fertilizers as they will feed your grass slowly for a long time.
Lack of potassium is a significant problem for any homeowner who wants to have a nice yard. Besides grass it also affects other plants in your garden; this is why you need to test your soil regularly to ensure it has enough potassium.
Now that you know how to add potassium to the lawn you shouldn’t have any issue regulating potassium levels in your soil. It is easy to handle the potassium problem, whether in your yard or garden. Always ensure you test your soil at least twice a year for an updated review. Happy gardening!
