What does this test for

testing by a certified lab

Each Tap Score Essential Soil Test package includes sampling materials for one (1) soil sample including Macro- and Micronutrients, as well as metals and other vital soil health characteristics – such as lime, pH, and organic matter.

These characterizations allow us (and you) to figure out what is missing, what is wrong, and ultimately how to improve your soil quality and your plants’ health. We will guide you in your decision-making process about restoring your soil's health based on your lab results.


Indicates your soil’s acidity or alkalinity on a scale of 0 to 14.

Electrical conductivity (soluble salts)

Different plants vary widely in their tolerance to soluble salts. Therefore, the values reported for your plants are interpreted in relative terms.

Soil Organic Matter (SOM)

The amount of plant and animal residue present in your soil is known as the Soil Organic Matter (SOM). This is reported as percent of total soil.

Nitrate as Nitrogen (NO3-N)

Nitrate is critical to plant growth and production. The nitrate measured is soluble and readily available for your plants to uptake as fertilizer.

Plant Macronutrients

Phosphorus, Potassium, Nitrogen

Plant Micronutrients

Zinc, Iron, Copper, Manganese, Boron, Molybdenum

Non-essential Elements

Lead, Cadmium, Chromium

Lime (CaCO3)

Lime is measured in the laboratory as calcium carbonate (CaCO3). Lime effects pH, is often a critical source of calcium and magnesium, improves water flow in soil, and supports the uptake of critical plant nutrients.
