Is eating vegetables with chemical fertilizers harmful to people's health?

Fertilizers are all composed of different salts, so long-term and large-scale application of these fertilizers composed of salt will increase the concentration of soil solution and produce different osmotic pressure when the fertilizer enters the soil. Crop root cells will not absorb water from the soil solution, but will pour water from cytoplasm into the soil solution, which will lead to crop damage. The "burning seedlings" of crops is a typical example.

After a large number of pesticides are applied, pesticide residues or deep groundwater are caused, and water sources are also polluted. In recent years, the low price of garlic is caused by excessive pesticide residues and the cancellation of purchases by foreign buyers. What we eat ourselves may not pass the test, but the awareness of the domestic people is not so high, and the cost of testing ourselves is too high. Ordinary people can't afford it.

Ways to reduce the amount of chemical fertilizer:

In response to the consumption of chemical fertilizers and pesticides, Minister of Agriculture Han Changfu said after passing through the "Ministerial Channel" of the Great Hall of the People that the next step will be to continuously promote the reduction and efficiency increase of chemical fertilizers and pesticides around three aspects: key varieties, new business entities and scientific and technological innovation.

Han Changfu said that in terms of key varieties, organic fertilizer will be promoted to replace chemical fertilizer in fruit and vegetable tea production counties, and green prevention and control and biological control will be promoted; In terms of new business entities, guide new business entities such as family farms, cooperatives and leading enterprises to take the lead in reducing the use of chemical fertilizers and pesticides; Scientific and technological innovation will improve the scientific and effective use of fertilizers and pesticides.

Through the government's measures such as purchasing services and subsidizing organic fertilizers, we will promote the reduction of chemical fertilizers and pesticides and increase efficiency. Han Changfu said that excessive use of chemical fertilizers and pesticides not only increased production costs, but also had a negative impact on the ecological environment. To this end, the Ministry of Agriculture proposes to strive to achieve zero growth in the use of chemical fertilizers and pesticides for major crops by 2020. At present, the use of pesticides in China has been negative for three consecutive years, and the use of chemical fertilizers has achieved zero growth.
