In agriculture, soil vapor testing is the examination of a soil sample for the number of nutrients and the composition of other substances, which can also include pollutants and toxins. In general, soil surveys are carried out to measure soil fertility and to identify existing deficiencies. Soil vapor testing is usually carried out in research laboratories that offer a distinct and extensive range of specialized tests.

The type of laboratory location you choose will also affect the results, and while there are many soil vapor testing laboratories everywhere, you should first conduct an independent study to determine which laboratory performs quality testing for the best results. 

The main nutrients tested include phosphorus, potassium, and nitrogen. Secondary nutrients include magnesium, sulfur, and calcium, while secondary nutrients include aluminum, zinc, manganese, boron, iron, and molybdenum. The test does not end there because the properties of the soil also need to be checked. 

Soil testing is a relatively easy way to manage horticultural as well as agronomic soils. It shows the pH level and key nutrients of the soil as well as the number of available pollutants and it will help producers a lot in choosing the right fertilizer.
