Why should you sample your soil?
Soil sampling is like a medical "checkup." Doctors do not prescribe medication without one. Without an analysis of your soil, you are guessing what plant food your soil requires to reach its optimum levels.

What do you get from your soil sample?
When you send a sample of your soil to the soil lab, you receive an analysis that tells you the existing condition of your soil.
Along with an interpretation of the results that will include nitrogen, phosphorus, potassium and pH recommendations.

What do you do with the soil analysis?
Tell the lab what you plan to grow. Nutrient recommendations will be based upon your current analysis and the type of plants.
Use your recommendations to select the proper plant food and the quantity the soil requires reaching its optimum levels.

How many soil samples should you take?
Take as many samples as you have areas that will be treated individually.

How often should you sample?
It depends on the nutrient "health" of your soil.
If you do not have any major problems, you should sample every third year or so. If you have problems, you should sample annually until the problems are corrected.
