We have finally found an easy-to-use plant nitrate test that will give you results in 30 minutes. Now you can eliminate the hassles, time and expense of sending samples to a lab. Everything you need to test nitrate levels is included in each kit, including a standard to compare to the color of your individual samples. Find out if your plants need additional nitrogen fertilizer or if they are ready to harvest by a change in nitrate levels. Any leaf, stalk or root can be tested. A garlic press or clean pliers is required to extract sap. Testing range is 0-1,000 ppm and standard is 500 ppm nitrate-N. Five-test kits include one standard, and 25-test kits include five standards. Instructions included. USA made. Specify either five- or 25-test kit.
