Our Review
The Rapitest 1601 is the right tool for a specific job: quick, same-day soil checks when you don't need the full nutrient picture. You mix soil with the included capsule solution, compare the color to the reference chart, and in minutes you have a pH reading plus N, P, and K levels. It won't give you manganese, boron, or magnesium — for that you need a lab test. But when you've just applied lime and want to check your pH progress in 60 days, or you're deciding whether to add starter fertilizer based on current phosphorus levels, the Rapitest delivers instantly. The 40-test count (10 each of pH, N, P, K) is enough to monitor multiple zones across multiple seasons. Extension offices nationwide recommend it as a basic diagnostic tool. At under $20, it's a useful complement to a lab test — use MySoil once for the full picture, then Rapitest throughout the season to track amendment progress.
