Keep your garden soil in good condition with this 40-Test Soil Testing Kit. Designed to measure soil pH, nitrogen (N), phosphorus (P) and potassium (K), this easy-to-use garden soil test kit helps identify nutrient imbalances and improve growing conditions for vegetables, flowers, shrubs and other garden plants.

With 10 tests for each element, the kit allows gardeners to monitor soil quality, choose suitable plants and support healthy growth throughout the growing season.

Why Test Your Garden Soil?

Regular soil testing helps you understand your soil's acidity, alkalinity and essential nutrient levels. Knowing these factors allows you to make informed decisions about planting, fertilisers and soil improvements.

  • Soil pH: Measures soil acidity or alkalinity, helping you determine whether conditions are suitable for effective nutrient absorption.
  • Nitrogen (N): Supports healthy plant growth, including the development of stems, roots and new buds.
  • Phosphorus (P): Essential for strong root development, particularly in root vegetables, and supports healthy stems and bud formation.
  • Potassium (K): Encourages healthy shrubs and flowering plants, helping improve flower colour and scent while supporting better-quality vegetable crops.

What's Included in the Soil Testing Kit?

The kit contains 40 individual soil tests:

  • 10 x Soil pH Tests
  • 10 x Nitrogen (N) Tests
  • 10 x Phosphorus (P) Tests
  • 10 x Potassium (K) Tests

When Should You Test Your Soil?

Spring: Test soil pH, nitrogen, phosphorus and potassium levels before planting seeds, vegetables and flowers.

Growing Season: Check soil conditions if plants show signs of weak growth or possible nutrient deficiencies.

Autumn: Test soil pH, phosphorus and potassium when preparing garden beds for the following growing season.

How to Use the Soil Test Kit

  1. Collect a soil sample following the supplied instructions.
  2. Prepare the sample and carry out the required test.
  3. Allow the test to develop as directed.
  4. Compare the liquid colour with the colour chart on the box.
  5. Use the results to assess soil conditions and identify any improvements needed.

Benefits of Using a Garden Soil Testing Kit

  • Helps identify possible nutrient deficiencies and imbalances.
  • Supports better fertiliser and soil amendment decisions.
  • Helps improve growing conditions for vegetables, flowers and shrubs.
  • Allows regular monitoring of garden soil throughout the growing season.
  • Provides an easy-to-use colour comparison testing method.

Frequently Asked Questions

Why doesn't my soil test liquid match the colour chart?

If the liquid develops a colour that does not match the chart, the soil may have been too cold during testing. Ensure the soil is at room temperature, approximately 19°C, before starting.

The test may also need longer to develop. Leave it for up to 24 hours and check again. If the result remains unclear, repeat the test, ensuring all measurements are accurate and the sample is thoroughly mixed.

What does this soil testing kit measure?

The kit measures soil pH, nitrogen, phosphorus and potassium to help gardeners understand soil acidity, alkalinity and nutrient levels.

How many tests are included?

There are 40 tests in total, including 10 tests each for pH, nitrogen, phosphorus and potassium.

Can I use this kit for vegetable gardens and flower beds?

Yes, the soil testing kit is suitable for assessing soil conditions for vegetables, flowers, shrubs and other garden plants.

When is the best time to test garden soil?

Soil testing is particularly useful before spring planting and when preparing autumn beds. Additional tests can be carried out if plants show signs of poor growth.
