Things You Need to Know Before Buying Fertilizer

When you are buying the fertilizer, make sure you get the right one. For instance, get the product which is suitable for your lawn , has lesser side effects and more benefits. To make it easier for you, we have elaborated a few things you need to know before buying fertilizer.

Fertilizer Analysis

You must know how to read the fertilizer’s packet. There is no need to worry if you have no knowledge of the elements, we will give a brief explanation to do better analysis of your fertilizer. Usually, you will find the letters N, P, K with the percentages. These N, P, K, are the three most vital nutrients for the plants i.e., nitrogen, phosphorus and potassium.

The nitrogen is responsible for making your grass green and thicker as it helps in creating more chlorophyl. Moreover, the phosphorus, helps in strengthening the roots and make the ground ready for new implantation of grass. Whereas, potassium comes to rescue when there is drought, or any disease to give more immunity to the grass strands.

Usually, there is enough amount of phosphorus in the lawn so you need to check the percentage of this nutrient in the fertilizer. However, you should buy the product according to the nutritional need of your law. For this purpose, do a thorough analysis of fertilizer’s npk ratio to avoid oversupply of nutrients.

Chemical Fertilizer vs. Organic Fertilizer

We are the impatient beings who hate to wait for long. Therefore, most of the lawn owners or the gardeners tend to get the chemical fertilizers. These synthetic fertilizers may show instant or prompt results but they are not long lasting and have many disadvantages. Whereas the wise ones get the organic fertilizers to provide important nutrients and less harmful substances.

The synthetic fertilizers most of the times do not fully absorb in the roots. Instead, they sit on the upper surface, catalyze quick result and then wash off with water or rain. In such cases, the chemicals pollute the water supplies and can cause mineral depletion in the soil. Also, if used in a heavy amount, it can burn the grass instead of increasing the growth.

In contrast, the organic fertilizers are best suited for the lawn grass. They might have slow response rate but they have long lasting effects. Usually, these fertilizers come from bone meal, sea weed, fossils, manure etc. These organic fertilizers release the nutrients in soil slowly, which helps them in better absorption in the soil and roots while posing less threats to environment.

Your Lawn’s Soil Test Results

The most important thing to consider while buying a lawn fertilizer, is your lawn’s soil test result. If you take this test, it can save your lawn from great damage and ensure proper and required care. Basically, there are two types of soils either alkaline or acidic. The soil test shows whether your soil has more alkalinity or acidity. So you can get the fertilizer accordingly.

If your lawn’s soil is alkaline in nature you need to get the fertilizer rich in nitrogen and iron sulfate. Make sure you get the fertilizer which has organic nitrogen to avoid further harm to the grass. However, if your soil is acidic then you must get limestone rich fertilizer to raise the Ph level of lawn’s soil.

Once you have the soil test results, try to follow them and buy the fertilizer as per the needs of lawn’s soil. If you add the required nutrients can facilitate the grass growth and make it stay all fresh and green throughout the seasons.

Yard Size

Examining the yard size is yet another kind of fertilizer analysis. You should measure or calculate the size of your lawn and the required amount of fertilizer. It highly depends on the size , how much fertilizer you should add.

For this reason, you need to be mindfull of the lawn’s size and area when buying a lawn fertilizer. You cannot add excess amount to a smaller yad or lesser amount to a huge yard. In both the cases, the performance of the product and the results will be affected.

Most of the organic fertilizer brands mention the standard size on the packets. So, it makes it easier for you to get the right product based on your yard’s size. To ensure, good health and growth of grass in your backyard.
