A soil test kit that measures soil pH and the primary nutrients nitrogen, phosphorus and potassium using a capsule system and color comparators. It includes materials for 20 tests (five each for pH, N, P and K), simple instructions, and a soil pH preference list for over 450 plants.
Project Ideas
Business
Mobile Soil Testing Service
Offer on-site soil testing for homeowners, landscapers, and small farms using the kit to deliver immediate pH and N/P/K readings. Provide a printed or emailed report with clear interpretation and actionable recommendations (amendment type and quantities, plant suggestions). Package tiers: single-visit audit, multi-spot mapping, and seasonal retest subscription; charge per-site plus a premium for laminated action plans.
Community Garden Consultant
Partner with community gardens, schools, and urban farms to perform baseline soil assessments with the kit, then design amendment plans and crop rotations. Offer workshops for volunteer coordinators on interpreting results and using amendments correctly. Revenue streams: consulting fees, recurring monitoring contracts, and selling pre-measured amendment kits matched to the garden's needs.
Hands-On Workshops & Pop-Up Classes
Host fee-based classes where attendees learn to test their soil and interpret pH and nutrient results using the kit. Include a short lecture on plant preferences, a hands-on testing session, and take-home sheets. Upsell opportunities: sell the test kits, starter amendment bundles, or private follow-up consultations. Market to neighborhood associations, garden clubs, and hardware stores.
Retail Value-Added Bundles for Nurseries
Create a co-branded bundle sold through garden centers: a plant (or seed starter kit) plus one RapiTest kit and a custom care card that explains the optimal pH and fertilization schedule for that plant. Nurseries can use this to reduce returns and increase customer success. Offer training for staff on how to demo the kit and read results so they can recommend the right products.
Pre-Listing Landscaping & Soil Prep Service
Target real estate agents and homeowners preparing to sell: perform quick soil tests and produce a prioritized remediation plan to improve lawn and garden curb appeal. Use the kit to identify pH or nutrient imbalances that might cause yellowing or poor growth, recommend fast-acting fixes, and provide before/after documentation to include in listings. Charge a flat fee per property and offer bundled follow-up visits for guaranteed results.
Creative
pH Gradient Garden
Design a long bed or series of planters that intentionally moves from acidic to alkaline soil using the kit to measure pH at regular intervals. Use the results to choose plants that prefer each zone and plant them in a visible gradient (e.g., blueberries at the acidic end, lavender toward the alkaline end). Document the process with before/after photos and a simple sign explaining the pH gradient so visitors can learn by looking.
Soil-Color Mapping Art Installation
Create a visual map of your yard or neighborhood by testing soil at a grid of points and mounting painted wooden stakes or tiles that reflect the kit's color comparator results for pH and nutrients. Arrange the stakes as a mosaic or sculpture in a frame or on a garden wall that shows hot and poor spots for N, P, K and pH. This doubles as art and a functional reference for planting decisions.
Kids' Soil Science Explorations
Turn the 20-test kit into an educational activity for children: assemble simple worksheets, hypotheses prompts (What happens if we add lime?), and small pots for experiments. Have kids test soil from different places (play area, garden bed, near trees), record results, plant fast-growing seeds (radish, cress), and track growth differences tied to soil nutrients and pH. This makes a fun STEM project for camps, classrooms, or family weekends.
Micro-Garden Matchboxes
Build a series of themed mini-planters (herb box, salad box, pollinator mix) tailored to the actual soil conditions you measure. Use the kit to test the soil that will supply each planter and then formulate the right amendment and plant list. Package each planter with a small card that shows the measured pH/N/P/K values, what you amended, and care tips—great for gifting or farmers' market display.
Fertilizer Follow-up Trial
Use the kit for a paired-plot experiment: test two identical plots, apply a specific amendment to one (lime, compost, granular fertilizer) and leave the other as control. Track pH and nutrient levels over time with the kit's remaining tests and photograph differences in plant vigor and yield. Turn results into a short guide or series of social posts showing evidence-based amendment strategies.
