TPSL® Soil Test for Trees & Shrubs
Tree and Shrub Soil Test Package
Trees and shrubs have deep root systems, making it essential to analyze both the topsoil and subsoil to understand what’s happening around the roots. This comprehensive test package consists of two separate analyses: one for the topsoil and another for the subsoil.
If your nut and fruit trees are no longer producing as they used to, or if your prized ornamentals are looking less vibrant, this is the test you need to identify the problem and implement effective solutions.
How to Collect Your Samples:
- Where to Sample: Dig within the drip line (the farthest-reaching branches) and the trunk of the tree or shrub.
- Separate Samples: Place topsoil and subsoil into separate bags to prevent mixing. Topsoil should be taken from 0-12 inches, and subsoil from 12-24 inches.
What’s Included in Your Analysis:
Topsoil Analysis:
| Texture & pH | Carbonates (CO3) |
% Active Organic Matter | Electrical Conductivity (EC) |
| Nitrate-Nitrogen (NO3-N) | Phosphate (P2O5) | Potassium (H2O & CO2) | Sodium (H2O & CO2) |
| Calcium (H2O & CO2) | Magnesium (H2O & CO2) | Na:Ca & Na: Mg Ratios | Boron (B) |
| Zinc (Zn) |
Iron (Fe) |
Manganese (Mn) | Copper (Cu) |

Subsoil Analysis:
| Texture | pH | Carbonates (CO3) |
Electrical Conductivity (EC) |
| Nitrate-Nitrogen (NO3-N) | Phosphate (P2O5) | Potassium (H2O & CO2) | Sodium (H2O & CO2) |
| Calcium (H2O & CO2) | Magnesium (H2O & CO2) | Na:Ca Ratio | Na:Mg Ratio |
Two soil samples are needed for this analysis - one topsoil (0-12") and one subsoil (12-24")
Additional Information:
- Minimum Sample Size Required: 3-4 cups per sample (topsoil and subsoil).
- Turnaround Time: 5-7 business days.
- Sampling Kit: Not included. A quart-sized Ziploc bag works perfectly for collecting and shipping your samples.
Personalized Guidance:
- Custom Fertilizer Recommendations: Based on your results and tailored to the specific type of tree or shrub (indicate this clearly on your submittal form).
