Plant Petiole Nitrate Test Kit
$45.00Learn MoreProduct 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.

Green Forage Nitrate Test Kits
$45.00Learn MoreProduct 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
The USDA maintains a "US Drought Map" showing areas of concern. View HERE.
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.

Drought may lead to excess nitrate uptake leading to toxicity
The USDA maintains a "US Drought Map" showing areas of concern. View HERE.
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.
