  • Dry Forage Nitrate Test Kit

    Dry Forage Nitrate Test Kit

    $40.00
    Learn More

    Product ID: NTK-DF

    Ensure Your Livestock Feed is Safe for Consumption

    Easy to Use, Quick and Reliable Results, Environmentally Benign

    Use the NECi Nitrate Test Kit for Dry Forage to prevent livestock toxicity from excess nitrate, often caused by drought conditions.  Obtain accurate and reliable results in less than an hour.  These enzyme based test kits are non-toxic and environmentally benign.

    Drought may lead to excess nitrate uptake leading to toxicity

    Test for nitrate levels in dry forage to check for nitrate toxicity.  Drought may cause stress in plants, encouraging excess nitrate uptake.  Too much nitrate may lead to illness or even death in livestock, especially pregnant and lactating animals or young animals.  

    Test for nitrate levels in very dry livestock feed when samples are too dry to squeeze liquid out (dry hay, corn stalks, drought-stricken crops) to check for nitrate toxicity.  This kit will detect 0 - 9000 ppm nitrate (0 - 2000 ppm nitrate-N or up to 0.9% N).   All you need is a blender or grinder to prepare your samples, a pen, marker, and a pair of scissors.  No lab experience needed, kits are ready and easy to use.

    Available in kit sizes to measure nitrate content of 5, 10, 25, or 50 samples

    Two Ways to Improve Your Nitrate Testing Experience

    Use our New Handheld Photometer

    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.

    Download the Free Nitrate Color Slider App

    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.

    Product ID: NTK-GF

    Maximize Yield and Reduce Costly Fertilizer Application

    Quick and Reliable Results, Easy to Use, Environmentally Benign

    Use the NECi Nitrate Test Kit for Livestock Feed to prevent livestock toxicity from excess nitrate, often caused by drought conditions.  Obtain accurate and reliable results in less than an hour.  These enzyme based test kits are non-toxic and environmentally benign.

    Drought may lead to excess nitrate uptake leading to toxicity

    Test for nitrate levels in wet livestock feed (green chop, standing hay, and silage) to check for nitrate toxicity.  Drought may cause stress in plants, encouraging excess nitrate uptake.  Too much nitrate may lead to illness or even death in livestock, especially pregnant and lactating animals or young animals.  

    Use this kit where sap or a wet extract is available.  This kit will detect 0 - 9000 ppm nitrate (0 - 2000 ppm nitrate-N or up to 0.9% N).  All you need in addition to this kit is a garlic press or similar apparatus to squeeze plant sap from your samples.  Kits are designed to be easy to use, provide accurate and reliable results, and contain no toxic materials.  

    Choose from kit packs for 5, 10, 25, or 50 samples.

    Product ID: NTK-P

    Maximize Yield and Reduce Costly Fertilizer Application

    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.

    Microplate Format Nitrate Test Kits

    $125.00
    Learn More

    Product ID: NTK-MPLR or NTK-MPSR

    Use this kit for quantification of nitrate in essentially any aqueous sample.  Reactions occur on a 96-well microplate provided with the kit.  This test kit is based on the enzyme Nitrate Reductase (NaR), catalyzing the reduction of nitrate to nitrite using the natural electron donor NADH.  The nitrite reacts with color reagents under acidic conditions to produce a visible color. The concentration of nitrate in the original sample is determined by measuring absorbance with a microplate reader using a 540 nm filter, versus nitrate concentration in nitrate standards.

    Nitrate Reductase Based Microplate Test Kit Available in:

    • Standard Range (1.0 ppm - 10.0 ppm Nitrate-N) or Low Range (0.5 ppm - 1.0 ppm Nitrate-N)
    • Freshwater or Saltwater Analysis
