Quick and Reliable Results, Easy to Use, Environmentally Benign
Use this kit to test for nitrate levels in plants and hone in on appropriate fertilizer application. Plant nutrient levels can change quickly, especially during rapid growth phases. Test corn and cotton stalks or the sap from petioles of leafy crops to monitor nitrate level fluctuations. For best results, refer to a Certified Crop Advisor for plant sampling advice. Refer to the Petiole Sap Nitrate Guidelines under Related Information for testing crop petioles.
This kit will detect 0 ppm - 1000 ppm Nitrate-N. (1000 ppm Nitrate-N = 5000 ppm Nitrate)
Reaction occurs within 30 minutes. Choose from test kits in packs of 5, 10, 25, or 50. All you need is a garlic press or similar device to squeeze out sample liquid from your plants.
Check out our new handheld photometer which displays and tracks nitrate and phosphate results digitally on Android mobile devices. Obtain near lab-quality data without needing laboratory equipment or experience. Our Introductory Photometer Package is complete with the photometer, instructions, and a 10-sample test kit pack of your choice. Use your own Android mobile device, or add-on a control pad tablet for tracking, storage, and sharing of data.
For a free interactive color-matching tool, use our free nitrate color slider app for easier visual analysis of colorimetric results. Instead of using the color chart provided in the instructions, simply match the color on the screen with the color of each sample for more precise numerical values. This app is available on the Apple App and Google Play stores.
