Carrots have an important role for a life of the men. Everybody can use carrots in the meals or the drinks, he uses carrots such as the medicaments to cure many diseases, too. Carrots are very necessary, we can tell the following effects: carrots help improve eyesight, especially, carrots contain vitamin A, essential nutrients for health of the eyes.

Carrots contain a lot of beta carotene, fiber, vitamin K1, potassium as well as antioxidants and are grown popularly in all regions of Vietnam. The cultivating soil, irrigating water and carrot samples were collected in Loc Thanh village, Bao Lam district, Lam Dong province and some indicators were analyzed. The results showed that the soil sample was poor in nutrient by N, P, K indicators that were lower than the standards; but pH, Al3+ and Fe3+ were higher than the standards. The water sample did not contain the toxic heavy metals such as: As, Pb, Cd; but the indicators of Cu, Zn, Fe were higher than the standards. For the carrot sample, the indicators of As, Pb, Cu, Zn exceeded the allowable threshold; the contents of lipid and protein were lower than the standards but NO3- was within allowable standards. However, analysis of carrot samples grown by us using organic methods showed that some heavy metal indicators such as: As, Pb, Cu were lower than allowable standards. This showed that it is necessary to choose the type of soil, water and organic method for growing carrots in order to harvest good quality carrots and safety for users. We studied an environment of soil, water and analyzed the carrots to find a nutrition level, nutritional value and the metal accumulation in order to improve a life of men.
