The Importance of Soil Analysis

The first step toward a more balanced outdoor environment is professional soil testing, which can help to determine the exact composition and nutrient levels in your soil. Once you have identified any deficiencies, you can develop a plan to amend the soil to suit your needs based on the following:


There are 17 different nutrients needed at various ratios for general plant health. Nitrogen (N), Phosphorus (P), and Potassium (K) are the three key nutrients needed by all plants and found in most fertilizers.

pH Levels

pH is measured on a scale between 1.0 and 14.0, with the median ranking of 7.0 being considered a neutral pH level. Neither extreme is desirable in most cases, as plants tend to prefer levels that range between 6.0 and 7.5. The lower the number, the more acidic the soil (preferred by blueberries and azaleas), while numbers that are increasingly higher than 7.0 indicate higher alkalinity (preferred by ferns and geraniums).


Dependent on your geographic location your soil may be mixed with sand, clay, limestone or manufactured dirt. Soil that is too sandy or too dense can hinder water absorption or drainage. While most soil can be categorized as somewhere in between, the ideal texture should be light enough to allow the passage of water and air, with enough density to provide adequate moisture and nutrients to your plants.

Tips for Soil Amendment

Once the analysis is complete, you can begin taking steps toward improving the quality of your soil. This consists of breaking up the ground before working in the necessary materials. Whether you need tips on how to amend soil for vegetable gardening or how to amend clay soil, the following information can help you to succeed:

Add Nutrients

Organic matter or inorganic fertilizer can be added to soil that is lacking the essential nutrients. The right commercial fertilizer can produce fast results, but the downside is the cost and the long term, negative effects it can have on your plants and soil. Organic materials such as compost, lawn clippings, bone meal, or peat moss are a much safer alternative and better for the environment.

Adjust the pH Level

Soil that is too alkaline may benefit from the addition of elemental sulfur or coffee grounds, while soil that is too acidic can be balanced by adding lime, wood ash, or poultry manure. Amend the soil in stages, adding no more than five pounds of lime or sulfur for every 100 square feet of space.

Amend the Soil Texture

If you are wondering how to amend clay soil for grass, peat moss is a great addition that is both inexpensive and effective. Compost can be used to enrich sandy soil while adding much-needed structure and stability.
