Efforts to grow organic vegetables that cause much less damage to farmland have paid off as China’s southwest Yunnan Province has tried to fulfill its promise to better protect its natural resources.
In the track field under the guidance of Yunling Organic Agriculture Development Co., Ltd, soil organic matter has been improved while the content of some heavy metals has been reduced since the start of the organic planting project in 2017. The green manure they use has left close to little pollution in the soil, which is critically important as the field which covers 240 hectares of land is located right in the middle of the Kunming Songhuaba Reservoir Nature Reserve.
“Our fertilizer is the result of the fermented mixture of livestock waste and harvest straw.” said Zhang Jian, deputy general manager of Yunling Organic Agriculture Development Co., Ltd. “After several years of planting trials, there is evidence that the development of organic farming in sensitive water source areas plays a positive role in soil improvement and ecological restoration. “
Today, more than 50 tons of vegetables of more than 20 varieties from the field are sent all over China every day. Although the price is three to five times higher than that of ordinary vegetables, it is popular in middle and high-end retail markets in eastern, central and southern China. In Tonghai County, one of the main production areas, organic vegetables have started to enter the Southeast Asian market.
Currently, Yunnan produces 32 million tons of vegetables per year. With the promotion of organic farming, the market gardening sector is facing a major transformation.
“A revolutionary change should be made to the traditional cultivation mode or cultivation technology. If zero chemical residue emission is achieved, our environmental pollution problems will be solved,” said He Jiangming, a researcher at the Institute of Horticulture, Yunnan Academy of Sciences.
