It is not possible to generalize that organic agricultural products cannot use pesticides at all. and chemical fertilizers. If you want to talk about the stage of organic cultivation, it should be explained that the use of pesticides in organic agricultural products is mainly limited to natural substances and a few available chemical substances, and the available fertilizers are mainly natural or some of the listed chemical fertilizers. According to the information released by the Council of Agriculture (2022), the total area of organic agriculture in Taiwan currently
accounts for about 1% of the cultivated old picture restoration land area. of 12,153.9 hectares, there is still considerable room for efforts to implement it.

Organic Label Determination Standards Just for Market Existence? Professor Xu Zhengyi of the Department of Agricultural Chemistry of National Taiwan University said that due to the geological conditions in Taiwan, the natural background values of heavy metals are relatively high. For example, shale alluvial plains have high arsenic and chromium content. All are relatively high,
with the average values (mg/kg) of arsenic, chromium and nickel in Taiwan's overall soil being 18, 50, and 60 in order. According to Article 4 of the "Soil Pollution Monitoring Standards", referring to the geological conditions of Taiwan, the upper limit of the monitoring of metals in the soil is listed. We take the three heavy metals that Professor Xu Zhengyi considers as the main high heavy metals, and the upper limit is 30 mg of arsenic respectively. /kg, chromium 175 mg/kg, nickel 130 mg/kg. According to the regulations, if the heavy metals in the soil exceed the monitoring standards,
