Biotech company finds new way to improve farmland
Print Edition
A BIOTECHNOLOGY company in Huating Town has developed a new kind of trichoderma, or fungus, which proved effective in improving the soil.
“In the past, farmers never thought of the long-term protection of soil,” said a Shanghai Dajing Biotechnology Co researcher at a vegetable planting base in Huating. Farmers often overused pesticides and chemical fertilizers, which seriously damaged nutrients in the soil, he said. “It’s not a small issue because it will lead to salinization, acidification and excess heavy metals in the soil.”
At the end of last year, Dajing and Huating Town cooperated to use the fungus to “cure” the soil. Trichoderma is an important part of microorganism in the soil. It has 31 varieties and can resist various pathogenic funguses, bacteria and pests. It’s popular abroad, but has not been used by domestic farmers until now.
After a year’s experiment on 3 hectares of farmland, salinization was reduced by about 40 percent, while fertilizer efficiency increased by 30 percent.
Now, agricultural workers in Huating are thinking of building a Huating Production Base. Wan Binbin, vice town mayor of Huating, said it will have a general plan for stock farmland and soil quality. The government will launch supervision on the safety, quality and output of the crops.
“Our current research now focuses on the new standard of soil quality, cost control and the industry-university-research cooperation,” said Tang Weidong, Dajing’s general manager.
Tang said the company recently worked with the local agricultural technology department and Shanghai Organic Fertilizer Association on integrating trichoderma into commercial organic fertilizers to make it more effective.
