Breaking Down the Importance of Soil Nutrients

Shopping for the right grass care products can be confusing and overwhelming, especially when you don't know what is causing your lawn issues. There are a variety of factors that can play into dry, brown, or patchy grass. You don't have to be an expert in lawn care to fix your grass issues - let your friends at Simple Lawn Solutions help guide the way to achieve a luscious lawn for all areas of grass care, starting with soil nutrients. 

Whether you’re looking to improve your lawn care or have a better understanding of your soil, we want to help you break down the importance of different lawn ingredients like potassium, nitrogen, and other organic components. Let’s get started in learning about the importance of grass care.


The Importance of Lawn Care

There is a sense of pride you get from attaining a well-maintained lawn, but keep in mind that there is more to excellent grass care than meets the eye. For proper lawn care, you will need to understand how soil, sunlight, water, and other elements all work together to provide the right environment for your grass to flourish.

Some ways to tell if your lawn requires acute grass care

  •     Thinning grass
  •     Brown spots
  •     Patches
  •     Weeds


In addition to regular mowing, weeding, and watering, there are two more easy processes to add to your lawn care routine to help with grass issues: lawn aeration and fertilization. Grass care issues could be coming from the ground, so it is essential to understand the nutrients that soil needs to thrive. The right fertilizer will help to mitigate any nutrient shortages. Along with proper nutrients and adequate lawn care, you can achieve an excellent lawn. Continue reading to learn about the benefits of going liquid with your lawn food and how adding this technique into your grass care routine can benefit your grass at the soil level.


Liquid Lawn Fertilizer Ingredients

Simple Lawn Solutions carries a variety of specially formulated lawn fertilizers. Whether your lawn requires an extra boost to grow tall, more durable blades, or better root development, we have the right formula for your lawn care needs.

Here are just three reasons why we love liquid fertilizer:  

  •     Easy-to-use (no spreading equipment required)
  •     Well-mixed nutrients for uniform application
  •     Fast results


Our lawn food provides a balanced amount of macronutrients: nitrogen, phosphorus, and potassium, also referred to as N-P-K. These nutrients are essential for grass health and growth. Along with these macronutrients, the liquid fertilizer also contains a proprietary mix of other nutrients necessary to treat any deficiencies your soil may have or just to help maintain a healthy lawn.

Our liquid fertilizer is homogeneous, so you will distribute the nutrients to your lawn equally during the application, making for more accessible grass care. This fertilizer penetrates the soil, enabling the enhanced health of both your grass and soil. With the right fertilizer and proper lawn care techniques, you will be on your way to vibrantly green and growing grass.

Conducting a Soil Test

Are you wondering how to tell which macronutrients your lawn needs? We recommend conducting a soil test - this can be done at home or by a professional lawn care service. Whether your results are ready in the same-day or need lab testing, a soil test will tell you the PH of your soil, so you will know whether it is acidic, neutral, or alkaline. A soil test might seem complicated, but it is only necessary when your lawn shows signs of deterioration or if you want to know the details of your soil’s nutrient count. Knowing the nutrient contents of your soil is beneficial for fertilization grass care, so you can be sure to add the right blend of N-P-K.

This test will also indicate which nutrients are lacking in your soil and should give you an idea of how much of that nutrient should be added back through fertilizer, to increase your soil’s health. We will be taking a deep dive into potassium, nitrogen, iron, and phosphorus and explore how you can combat these specific nutrient deficiencies. Consider adding a soil test to your annual grass care checklist. If your grass is doing well, you may only need to conduct a soil test when you notice your grass is stunted or deteriorating.

Not sure what to do with the results of your soil test? We will also help to recommend a specific fertilizer for each nutrient deficiency that your soil may be experiencing.

It’s very likely for many plants, like common grass, to be nitrogen-deficient. A lack of nitrogen in your yard's soil can be a significant contributor to your grasses growth and development.

If your grass shows any of these nitrogen-deficient symptoms, it’s time to explore our nitrogen-rich lawn foods: 
  •     Yellowing blades or leaves

  •     Stunned, slow growth

  •     Pale green color

  •     Poor density


An excellent way to combat nitrogen-deficient soil is to use a lawn fertilizer with a high-nitrogen blend. The grass cannot adequately absorb nitrogen without an established root system, which echoes the benefits of fertilizer use. Proper lawn care techniques work hand-in-hand with fertilization. If you fertilize stunted grassroots and your grass is unable to properly uptake the required nutrients, then applying a nitrogen-rich fertilizer to your grass will not be as impactful.

In the case of nitrogen, you can have too much of a good thing. An excess of nitrogen in the soil is harmful to the ground and makes a harsh environment for your grass to thrive. It is much easier to add nitrogen than to remove an excess of the nutrient, so make sure you conduct a proper soil test. Checking your soil's nitrogen content is vital before applying a type of fertilizer. 



Phosphorus is the second macronutrient that is part of the acronym N-P-K, commonly used in lawn care terminology. When it comes to lawns, phosphorus is tied to healthy root development but critical to the overall growth. A lack of phosphorus in your soil will present in your grass through slower growth, dark green or red patches, and a lower grass density. 

With soil lacking a vital nutrient like phosphorus, you will not be able to reach peak lawn care, no matter what techniques you are using. At Simple Lawn Solutions, we are invested in excellent grass care and stock our shop with the fertilizer blends for an excellent, healthy lawn. Our 3-18-18 blend of lawn food is high in phosphorus and potassium and works to increase the phosphates’ mobility. This carefully crafted blend aims to provide critical nutrients for top grass and root growth. 

Remember to assess your soil needs seasonally so you can apply the right blend of fertilizers and avoid overexposing your lawn to certain nutrients. Too much phosphorus in soil can cause stunted turf growth, so it is essential to pay close attention when maintaining grass care. We offer phosphorus-free fertilizers, such as our 15-0-15 blend, if your soil contains an adequate amount of this nutrient.

Consider testing your soil for phosphorus to ensure your soil has not too much and not too little, but an adequate amount of this nutrient. Let's learn about our third macronutrient, potassium, and how the lack of this nutrient in the soil can disturb your lawn health.



Is your lawn starting to look yellow instead of a healthy, vibrant green? Consider if your deteriorating lawn could be the result of too little potassium present in the ground. Yellowing grass leaves with brown, hot spots could be more than an indicator of failing grass care - it could mean that your soil does not have an adequate potassium amount. Potassium is one of the critical nutrients needed for a healthy, balanced soil. This nutrient plays an impactful role in photosynthesis, necessary for proper food production, and a necessary process for excellent lawn care. Without potassium, your lawn is unable to produce food material and will not have the proper energy to grow and thrive.

Our high potassium lawn food works in even the most potassium-deficient yards. This potassium-rich formula works to strengthen and preserve your lawn in the colder months so that you can show off a healthy, full turf in the spring and summer. If you don't need a high potassium dosage, check out our 16-4-8 lawn food,  a complete, well-rounded fertilizer. It consists of a blend of crucial macronutrients, including potassium. This high-quality, potassium-rich feed will aid in reviving your lawn to a healthy state. Our specially formulated liquid fertilizers are safe for all grass types, including Bermuda, Kentucky Bluegrass, and Fescue. Conduct a soil test and see if your turf can benefit from potassium-rich fertilization at the start of your seasonal lawn care routine.



Though it is not considered a vital soil macronutrient, iron is the fourth most prevalent nutrient found in soil and is a micronutrient. You can spot an iron deficiency in soil by the presence of iron chlorosis, or the yellowing of veins between grass leaves. This symptom is most common in younger grass, and in severe cases, coloring will be almost white in the leaf veins. You could be on the top of your A-game when it comes to grass care, but if your soil lacks vital nutrients, you will need to address the issue at the root.

When your grass lacks iron, it may compensate for the deficiency by creating a more acidic soil environment, which would create an imbalance. It's best to treat iron deficiency right away to keep your soil nutrients in harmony. When the nutrients in your soil are balanced, and you are applying the right and consistent grass care techniques, you will have no issues seeing your turf flourish.

For iron issues, we recommend using a specially designed micro booster. This booster contains chelated iron and key micronutrients that aid in healthy lawn care.

Unlike other fertilizers that specialize in a blend of macronutrients such as nitrogen, phosphorus, and potassium, this micro booster contains several micronutrients: 

  •     Iron
  •     Zinc
  •     Manganese
  •     Magnesium
  •     Sulfur


If your soil lacks one of these micronutrients, our lineup of boosters will have the blend that you can incorporate into your grass care proficiencies. This organic micro booster uses these nutrients to add high-quality mineral content that will increase your lawn's overall health and immunity. Consider adding this booster into your lawn care after a soil test or signs of iron-deficiency, or other micronutrients, are present in your soil. You can also use this booster as part of your weekly garden or grass care routine to improve the health and appearance of vegetables, citrus, trees, flowers, and bushes.

Lawn Aeration

Whether or not you need a lawn fertilizer or booster, there are still more tips to get you on your way to a healthy, luscious lawn. You can easily add lawn aeration to your seasonal grass care routine. With our Liquid Aerating Soil Loosener, the application is easy and does not require spiked shoes or heavy equipment. Use this lawn care technique to reduce soil compaction and prevent crusting. 

Lawn aeration provides an opening for soil, water, and fertilizer to penetrate deeper into the soil, making this process the perfect predecessor to liquid lawn food application. So if your soil lacks potassium, nitrogen, phosphorus, or any micronutrients, consider aeration before adding a liquid fertilizer for faster results and a more profound impact on the soil.
