What’s in the kit: The kit supplies liquid reagents for pH, ammonia, nitrogen, phosphorus and potassium testing, a larger sample vial for mixing your soil and water, a set of small reaction tubes, plastic droppers, a color comparison card and printed instructions updated for 2026. Altogether you get about 140 individual tests—approximately forty tests each for pH, phosphorus, potassium and ammonia, and roughly twenty tests for nitrogen.

Materials and component sizes: The collection uses lightweight plastic tubes and bottles with labeled reagent solutions. A larger mixing tube is provided to suspend soil in water for extraction; several very small reaction tubes are included to hold the test solution and reagent for color development. The tiny tubes have a limited capacity (they are compact and hold only fractions of a milliliter), and the kit’s droppers are sized for transferring measured drops into those reaction tubes. A laminated color chart helps translate color changes into approximate nutrient values.

How it’s used: Collect a soil sample, place a small scoop of soil into the main tube, add the indicated amount of water, shake to mix and let solids settle. Use the dropper to transfer a measured quantity of the clear extract into a small reaction tube, add the appropriate reagent for the nutrient being tested, then compare the resulting color against the included chart after the specified wait time. Each nutrient has its own reagent and a short step sequence printed in the manual and shown in accompanying demo material.

Who it’s for: The kit is intended for home gardeners, lawn care, small vegetable plots, flower beds, potted plants and basic hydroponic checks. It’s aimed at people who want to monitor soil fertility regularly without sending samples to a lab—helpful for adjusting fertilizer type and timing, avoiding over-application and improving plant health.

Performance notes: When protocol is followed accurately the kit yields clear, comparable color results that let you make practical feeding choices. Because the reaction tubes are small, precise droplet and timing technique is important. A few users have reported shipping damage or instruction inconsistencies; following the included demo or contacting support can resolve most issues.

VerdictA practical, budget-friendly option for routine soil checks: covers the key soil chemistry markers (pH, ammonia, N, P, K) and provides roughly 140 tests. Results are quick and useful for everyday gardening decisions, but accuracy depends on following the method closely. Some users report confusion over measurements and occasional shipping damage; customer support has resolved many issues. Good for

Quick delivery

Arrived very quickly. The kit seems to work well and I'm satisfied with the results.

Kindle Customer 5/5

Useful tool

Solid kit that helped me plan feeding more sensibly.

Seth Davis 3/5

Unexpected flat readings

All tests produced a flat-line result even after repeating samples. Garden is thriving so these low numbers surprised me.

Issue handled by seller

One reagent bottle arrived empty. I initially got no reply, but after posting feedback the seller contacted me and sent a brand new replacement kit at no charge. Very pleased with the resolution.

Larry Wilkes 4/5

As described

Simple to use. The results weren't what I hoped for, but they were the honest answers I needed.

JB 1/5

Confusing instructions and no reactions

Multiple instruction sheets contradict each other on volumes. The small tubes barely hold 0.5 mL, so the stated ratios are impossible to match. I guessed amounts but saw no color change in any test, so results felt unreliable.

Melissa 5/5

Great for a budget gardener

Affordable option with over 120 tests and quick results. Kit includes reagents for K, P, N and pH; instructions and a demo video made testing easy. Basic steps: add about an inch of soil to the large tube, mix with filtered water, shake, let settle ~30 minutes, then transfer extract into the small tube and add reagent.
