Every lawn program starts below the surface.
Soil testing through UMASS Amherst is mandatory for every Turf Manager customer, every 3 years. It's the difference between a real nutrient program and a guess.
Without a soil test, any lawn company is just guessing at what your lawn needs.
Testing removes the guesswork
Every 3 years, every customer
Soil chemistry shifts over time. Retesting on a set cycle keeps your program accurate instead of running on old assumptions.
Sent to a real lab, not a strip test
Samples go to the UMASS Amherst Soil & Plant Tissue Testing Lab for full chemical analysis, not a quick pH strip in the yard.
Your program follows the results
The nutrient recommendations that come back from the test directly shape your fertilizer, lime, and treatment plan — not the other way around.
The full picture, not just pH
The complete UMASS soil test covers a wide range of properties. These are the core measurements we weigh most heavily when building your program.
Soil pH
How acidic or alkaline your soil is — the single biggest factor in whether nutrients are actually available to your grass.
Phosphorus
Supports root development and early establishment, especially important for seeding and overseeding.
Potassium
Helps turf handle stress — heat, drought, foot traffic — and supports overall plant health.
Calcium
A key structural nutrient that also plays a role in how well your soil holds and releases other nutrients.
Magnesium
Works alongside calcium and potassium — imbalances here can affect color and nutrient uptake.
Aluminum
Elevated levels can interfere with root growth and nutrient availability, especially in more acidic soils.
Lead
A screening for legacy contamination, especially relevant on older properties in established neighborhoods.
Cation Exchange Capacity
A measure of how well your soil can hold onto and supply nutrients over time — your soil's overall "storage capacity."
Soil Organic Matter
Decomposed organic material that feeds soil biology and improves structure, water retention, and long-term fertility.

Here's what comes back from the lab
Every result is measured against known optimal ranges for turf, so we know exactly where your soil stands — and exactly what it needs next.

Where the recommendations live
The back of every UMASS soil test translates raw numbers into three specific recommendations. This is how your program gets built.
Lime Recommendation
How much lime, if any, your soil needs to bring pH into the optimal range for turf.
Phosphorus Recommendation
Whether your soil needs additional phosphorus, and how much, based on current levels.
Potassium Recommendation
The potassium input needed to round out your soil's nutrient profile for the season.
