Description / Luster Leaf® Rapitest® Soil Test Kit
Test your soil in minutes and enjoy healthy plants for years. This handy kit takes the guesswork out of amending your soil for the best possible growth, vigor, and bloom power in plants. It instantly reads the nitrogen, phosphorous, and potash of your soil, as well as the pH level. You can't go wrong.
Whenever you buy a bag or bottle of plant food, you see three numbers across the front. These are the N (Nitrogen), P (Phosphorous), and K (Potash) strengths. The amount you need of each varies from plant to plant and even season to season.
Nitrogen: Is essential for leaf growth and green coloration.
Phosphorous: Helps with plant growth, fruit and seed development, and disease resistance.
Potash: Strengthens the plant from the roots up.
pH: Simply measures the degree of alkalinity or acidity in the soil.Some plants need more of one or another; a few, such as hydrangea, will even change bloom color depending on pH.
With all this in mind, it's easy to see why a soil test can really benefit you before you plant out your garden. But it's also good for troubleshooting after you plant. If a plant is growing, coloring, flowering, or fruiting poorly, you can correct the soil once you know the specific mineral deficiencies.
This kit is easy to use, requiring only water and soil. The capsules included with the kit turn the test soil color within just 10 minutes, and then you compare the color of the solution with the included color chart. It's that easy to get ideal soil for all your plants.
This kit includes a list of the nutrient requirements of 450 common garden plants, so you needn't go running for the reference books whenever you perform a soil test. And the complete instructions included with the kit explain how to amend the soil to get just the mixture you need. There are even detailed lawn care instructions. Make the most of your garden with this simple and easy kit.
