Luster Leaf Professional Soil Test Kit 80 Tests (Green) — pH & N-P-K Liquid Tests, Portable Case

The Luster Leaf 1663 Professional Soil Test Kit supplies everything needed to run 80 liquid soil tests—20 each for pH, nitrogen, phosphorus and potash—so you can assess and adjust garden soil with confidence.

Quick, portable, and designed for hobbyists, classrooms and field professionals, this liquid-based kit gives a clear picture of core soil nutrients and acidity. The kit arrives in a sturdy plastic case with color-coded reagents, simple step-by-step instructions, and supplemental guides that explain which plants prefer which pH ranges and how to correct common nutrient imbalances.

How accurate and easy are the Luster Leaf 1663 tests to perform?

Each test uses liquid reagents and a color-comparison chart so you can get consistent results without specialized lab equipment. The procedures are short—collect a small soil sample, mix with the provided solution, and match the resulting color to the chart.

• Includes 20 tests per parameter: pH, nitrogen (N), phosphorus (P), potash (K)
• Color charts and reagents are pre-measured for consistent reactions
• Clear instructions reduce user error and speed up repeat testing

What specific soil information will this kit tell me?

The kit measures the four fundamentals gardeners most often need: soil acidity (pH) and the relative levels of N, P and K. Those readings identify whether your soil is deficient, adequate, or high in each nutrient so you can make targeted amendments.

• pH ranges that influence nutrient availability and plant selection
• Nitrogen levels for leafy growth and green vigor
• Phosphorus and potash readings to guide root development and flowering

How do the included guides and tips help me improve my soil?

The kit includes a plant pH preference list and practical amendment tips so you can match plant choices to existing soil or correct conditions for desired crops. Guidance covers common fixes—lime to raise pH, sulfur to lower pH, and suggested fertilizers to adjust N, P, K levels.

• Plant pH preference list for hundreds of species simplifies plant selection
• Step-by-step suggestions for common soil amendments and timing
• Practical classroom and hobbyist tips for repeat testing and record-keeping

What’s included in the kit and how long will it last?

The kit contains all reagents, test tubes, mixing tools, and a durable plastic case to protect components. With 20 tests per parameter you can monitor several beds, potted plants, or repeat seasonal checks for multiple years depending on usage.

• Total of 80 liquid tests: 20 pH, 20 N, 20 P, 20 K
• Sturdy plastic case keeps supplies organized and transportable
• Detailed instructions and reference materials included

Who this kit is for: the Luster Leaf 1663 is built for hobby gardeners who want reliable, hands-on results; teachers running classroom experiments; and landscaping or maintenance professionals needing a quick field check. It’s especially useful if you want to match plant choices to existing soil or plan targeted amendments without sending samples to a lab. The kit balances ease of use with enough tests to support seasonal monitoring, small-scale installations, or instructional use.
