The main pursuit of vegetable farming is economic benefits. Vegetable farmers often use chemical fertilizers in the production process, especially the use of nitrogen fertilizer alone, which exceeds the demand for vegetable growth. Some of them continue to topdress before harvesting, resulting in vegetables that are too late to feed all the fertilizers. It is synthesized as a nutrient and has to be stored in the form of nitrate.The vegetables with the highest nitrate content are cultivated in plastic greenhouses, which can be cultivated all year round. Most of the vegetables grown are “anti-season vegetables”.Since the growth period of the vegetable is short, the photosynthesis cannot be sufficiently performed, so that a large amount of nitrate is accumulated in the body.According to the data from the food analysis report, the nitrate in the organically cultivated spinach contains only 690 mg of nitrate, and the nitrate in the spinach is up to 3000 mg per kilogram.In addition, the nitrate remaining in the vegetable will be reduced to nitrite by the action of enzymes and bacteria.Greentest ECO 5F is a unique 6-in-1 nitrate, water hardness and radiation testing device. Developed using the latest in nitrate, water and radiation testing technology, the innovative Greentest ECO 5F detects nitrate levels in 64 of the most commonly consumed fruit and vegetables as well as all types of meat.Additionally, Greentest ECO 5F detects total dissolved solids (TDS) in water (or water hardness), as well as background radiation in your immediate environment alerting you to unsafe radiation exposure.Greentest ECO’s unique rapid analysis feature can tell you in just 3 seconds if your food, water or environment is harmful to your health.
