Custom Tests

EarthCo offers a select number of individual tests that are useful for monitoring nutrient levels or soil conditions. These tests are often chosen after you have made some correction to the soil (pH adjustment, soil amendment, nutrient deficiency) and want to follow the results. They are also helpful in plant problem diagnosis - when you want to isolate one variable and uncover some information that might lead to the reason behind a plant disorder. A few of these tests include the following. Click on Custom Tests to see a complete listing.

Soil pH (soil acidity and alkalinity)
Soluble Salts (deicing salts, fertilizer over application, pool drainage water)
Particle Size/Textural Analysis (% sand, silt, clay)
Soil Nitrogen (total nitrogen)
Phosphorus & Potassium (macronutrients)

Heavy metals are also of particular interest for gardeners as a soil contaminant, introduced through pesticides, petroleum products, lumber preservatives, paints or industrial processing materials. Some of the more requested tests include:

Lead (paint, gasoline, batteries)
Arsenic (treated lumber, pesticides)

A frequent request from gardeners is for a test that determines whether they have "toxic soil" or soil containing something that might harm people, pets or of concern when planting vegetables. "Toxic soil" is non-specific and something difficult to assess. If you have a concern for general soil contamination, ask Dr. GoodEarth for assistance.
