🧪 Preparing Your Soil Sample
Before testing, follow these steps to prepare your soil:
- Depth:
- For lawns, annuals, or houseplants: collect soil from 2–3 inches deep.
- For perennials, shrubs, vegetables, or fruits: collect from 4 inches deep.
- Clean the sample: Remove stones, roots, grass, and lime particles. Break up clumps and mix thoroughly.
- Drying (optional): Let the soil air dry to make handling easier, though it’s not strictly necessary.
🌱 pH Test Instructions (Green Comparator)
- Remove the cap from the green comparator and take out a green capsule.
- Ensure the color chart (film) is in place inside the comparator.
- Fill the test chamber to the soil line with your prepared soil.
- Open the capsule and pour the powder into the chamber.
- Add distilled water using the dropper until it reaches the water fill line.
- Cap the chamber tightly and shake thoroughly.
- Let it settle for about 1 minute.
- Compare the color of the solution to the pH chart in daylight (not direct sunlight).
🌾 Nitrogen, Phosphorus & Potash Tests (Purple, Blue, Orange Comparators)
- Mix soil and water:
- Combine 1 part soil with 5 parts distilled water (e.g., 1 cup soil + 5 cups water).
- Stir or shake vigorously for 1 minute.
- Let the mixture settle for 30 minutes to 24 hours (depending on soil type).
- Select the correct comparator:
- Purple = Nitrogen
- Blue = Phosphorus
- Orange = Potash
- Remove the cap and take out the matching capsule.
- Ensure the correct color chart is in place (don’t interchange charts).
- Fill the test chamber with the clear liquid from your soil-water mix.
- Add the capsule powder, close the cap, and shake thoroughly.
- Wait for color development, then compare to the chart.
📊 Interpreting Results
Each test will show a color that corresponds to a nutrient level:
- Low: Consider adding amendments or fertilizers.
- Medium: Usually sufficient for most plants.
- High: Avoid over-fertilizing, which can harm plants and soil health.
🌿 Adjusting Soil pH
If your pH is:
- Too low (acidic): Add lime.
- Too high (alkaline): Add sulfur or organic matter like compost.
Use the enclosed pH Preference List to match plant needs with soil conditions.
