Nitrate is a polyatomic ion which in big quantities can be toxic to human beings as the human body can transform nitrates into nitrite. Nitrite is dangerous for our health so the lower our nitrate intake is, the better it is for our health. Regarding the human consumption, the highest nitrate levels are mostly found in leafy vegetables (spinach, lettuce) and our drinking water.

137 (2)Aptus Plant Tech has developped a scientific proven method to lower nitrate levels in fruits and vegetables and at the same time maintain the yield and even enrich the nutrition content of harvested plants.

Years ago people thought nitrate in drinking water contributed to our health, but recent research starts saying otherwise. It shows not only infants must be monitored for their nitrate intake but also adults need to critically watch their intake, as not all consequences are obvious.

130Nitrates are mainly applied in fertilizers for agricultural crops because of their high solubility and availability. The main nitrates are connected to ammonium, sodium, potassium, and calcium salts. Several million of tons are produced annually for this purpose.

High levels of nitrate fertilization undoubtfully lead to higher levels of nitrate in the plant. In modern agriculture however, the use of huge amounts of nitrate seems to be taken for granted. While humans are subject to nitrate toxicity, farmers still use nitrates in excessive rates. Intensive testing and research shows when plants contain too high levels of nitrates, plants become more susceptible for infections and diseases and nutrition values diminish significantly.

491Lettuce grown in greenhouses with nitrate-rich fertilizer can contain up to 8 times higher levels of nitrate compared to vegetables grown in outdoor conditions.  We often observe that plants cannot transform nitrates sufficiently, what results into excessive nitrate levels in the plant. By this the plant becomes weaker, produces fruits or vegetables with low mineral content and low shelf life. Through plantjuice measurements in our lab we investigate techniques to better manage nitrogen fertilization and stimulate plants in more efficient transformation of nitrates. Multiple double blind trials on leafy vegetables showed:

  • Significantly lower nitrate levels in plants
  • Significantly higher brix rates
  • Improved mineral uptake = higher nutrition value of our food
