Iran

       The wide temperature differences in different parts of Iran and the diversity of climate zones allow people to grow a wide variety of crops, including cereals, fruits, vegetables, cotton, sugar cane, nuts, etc. About one-third of Iran's total land area is available for agriculture, but many of these areas are largely unused because of poor soil and inadequate water supplies. Only 12 percent of the country's land is used for cultivation, and the long-term irrational use of pesticides has caused great damage to the soil. We went to Iran to survey the soil conditions of saffron、tea and other producing areas. According to the current soil conditions, we promoted the use of organic fertilizers and arranged high-end customization of fertilizers for different crops to reduce the damage to soil, better restore soil conditions, and promote the increase of land income and production.
