USING THE RAPITEST SOIL TEST KIT
This Rapitest Soil Test Kit is designed for simplicity of use and accurate results. At the heart of the system are 4 patented, specially designed testing devices called “color comparators” - one each for pH, Nitrogen, Phosphorus and Potash. Each comparator has a removable film color chart and color coded top. Capsules for each test are also color-coded.
PREPARING YOUR SOIL SAMPLES
For lawns, annuals or house plants, take the soil sample from about 2-3" below the surface. For perennials especially shrubs, vegetables and fruit, the sample should be from 4” deep. Avoid touching the soil with your hands. Test different areas of your soil, as it may differ according to past cultivation, underlying soil differences or a localized condition. It is preferable to make individual tests on several samples from different areas, than to mix the samples together. Place your soil sample into a clean container. Break the sample up with the trowel or spoon and allow it to dry out naturally. This is not essential, however it makes working with the sample easier. Remove any small stones, organic material such as grass, weeds or roots and hard particles of lime. Then crumble the sample finely and mix it thoroughly.
SAFETY & HYGIENE
Dispose of test solutions by rinsing down the sink. Empty gelatin capsules should be disposed of immediately with household waste. Remove the color charts. Wash the comparators and caps in warm, soapy water immediately after each use. Make sure any sediment or color staining is removed. Rinse well and dry. Replace the color charts on the appropriate comparators. Each bag of capsules should be stored inside its comparator. Fit the caps on each comparator. Place all components back into the package. The blister pack has been specially designed to be reused as a storage container. Store your kit in clean, dry conditions, indoors. The powders are safe in normal domestic terms but like all chemicals & pharmaceuticals, they should be put away and kept out of reach of children. Try to avoid touching the powders. Always wash your hands thoroughly after making your tests. Do not eat, drink or smoke while using the soil test kit. Keep powders away from food, drink and animal feed. If taken internally, drink copious amounts of water and seek medical advice.
Where a lot of fertilizer is needed to correct one plant food, divide the applications over several weeks. Do not add lime and fertilizer together; lime first. Allow at least one month to pass before applying fertilizer. Retest 30 days after applying fertilizer.

What is the best liquid or granulated fertilizer for an average blue grass lawn?
When choosing a fertilizer, we always recommend getting a soil sample completed first so that you have a starting point when fertilizing your lawn. This will tell you what your lawn needs the most to make or keep it healthy. Quick release fertilizers make nitrogen available immediately to encourage a rapid recovery however, they can cause burnlike damage and too much can cause growth to quickly that can actually weaken your lawn in the long run. Slow release fertilizer provide nitrogen over a period of time and a steady rate, and are less likely to cause burn and can improve the overall health of your lawn. You can bring a soil sample to your local cooperative extension office for testing, or you can purchase a soil test kit.
