One morning before the Spring Festival this year, three men and a woman came to the village of Dafeng Township, Sheqi County, Henan Province, claiming to be the provincial agricultural city to promote new agricultural technologies. It also brought in the so-called new agricultural science and technology products --- “ Grain Feng Ling. ” At the same time, they showed the villagers samples of crops after using such fertilizers and claimed that they could increase the yield by 20% per acre with such “special effects medicated fertilizer” seed dressing or foliar spraying of food crops such as wheat and soybean.
