Why Choose Devil's Lettuce Test Labs

Welcome to Devils Lettuce Test Labs, your go-to destination for precise soil testing. Specializing in the analysis of nitrates, potassium, phosphorus, sodium, and calcium, our lab provides accurate results to support your agricultural or environmental needs.

Why Soil Testing?

Soil testing is essential for understanding the nutrient profile of your soil. It aids in optimizing plant growth, diagnosing soil problems, and preventing overuse of fertilizers. Our focus on key nutrients - nitrates, potassium, phosphorus, sodium, and calcium - ensures a comprehensive analysis crucial for soil health and productivity.

Technology

Our Horiba LaquaTwin meters provide quick and accurate testing for soil and water, using advanced ion-selective electrode (ISE) technology. With a compact design and flat sensor, they measure key nutrients like nitrate (NO3-), potassium (K+), and calcium (Ca2+) directly from small samples—requiring just 0.1 mL of liquid or a moist soil sample.

Sample Preperation

Gather your tools

A clean, dry soil probe, auger, or shovel.
A clean plastic bucket.
A dry, clean container for the soil sample (like a plastic zip-lock bag or jar with a tight lid).

Sampling time

Ideally, sample before fertilizing or a few weeks after planting.
Ensure the soil is not overly wet or dry during sampling.

Select sampling spots For Potted Plants

Select different pots to represent various plants or growth stages.
From each pot, dig about 3-4 inches deep and collect a small soil sample.
Place each sample in its own container, labeling them clearly.

Select Sampling Spots For Garden Plots

Choose several spots across the plot for a representative sample.
Dig holes about 6-8 inches deep and take a vertical soil slice from each.
Combine these slices in a bucket and mix thoroughly for a uniform composite sample.
After mixing, fill a container with this composite sample.

Dry The Samples

Spread each separate pot sample and/or the mixed garden plot sample on clean surfaces to air dry, avoiding direct sunlight or artificial heat.

Packaging

Once dry, ensure each pot sample is securely sealed in its labeled container.
Do the same for the garden plot composite sample.
Package each container carefully to prevent mixing during transit.
