Soil Analysis: The Key to Pest Free Plants.

A successful landscape or garden maintenance program strives to create a fertile soil. The goal of a sustainable fertility program is to activate a favorable environment for plants and millions of beneficial organisms. These microscopic critters assist plants in obtaining moisture and nutrients. Many of these creatures help resist drought and fight off a variety of pests including weeds, diseases, and insects.

A soil fertility program should feed the soil not the plant. By creating a fertile soil you will grow healthy, pest resistant plants. As a result, the need for costly pest control services is reduced. Specialty fertilizers (e.g., lawn food, rose and flower food, vegetable food) are designed to only feed the plant and ignore soil fertility.

To achieve a fertile soil the manager must first determine what nutrients are in short supply or are out of balance. The soil pH must be examined to make sure it is within a desirable range (6.3-7.0 for most plants). The organic matter content must also be checked. Soil testing is the only effective method to determine the condition of your soil and achieve a fertile living soil that will be able to provide the best environment for your landscape and garden.

There are two basic methods of soil testing. The first is to do it yourself by purchasing a soil test kit from a local nursery, hardware store, or mail order garden catalog. Kits test for the three major nutrients used by plants (nitrogen, phosphorous, potassium) as well as pH. The directions are simple and included with the kit. Making your own recommendations is not so easy.

A much more effective method of soil testing is to send your soil to a testing laboratory for analysis. It is more expensive, but the additional information obtained is worthwhile. In addition to nitrogen, phosphorus, potash, and pH, the lab will test for items such as micro-nutrients, percentage of organic matter, cation exchange capacity, and others (e.g., testing for lead in vegetable gardens is often available). They will also make recommendations on how to correct any problems found.

It is important when choosing a lab that you find a reputable service that can provide you with recommendations you can understand and that utilize organic management techniques.  This should include recommendations on soil fertilizers, cover crops, management techniques and necessary additions of organic materials.

Information provided from a quality testing service assists the landscape and garden manager in formulating a custom fertilizer blend for your garden or landscape. Utilizing these custom fertilizers will yield a fertile soil with abundant beneficial organisms that is capable of growing healthy, pest resistant plants.
