It stinks. That's because manure compost is used. In fact, feces contain a variety of pathogens, and the crops produced by composting with this stuff will have adverse effects on human body. I think the farm of the ecological group uses the quick-acting chemical fertilizer of QQ farm, which is collected every few minutes, of course, there is no pollution. As for the farms of industrial groups, although they also use quick-acting fertilizers, they have the habit of burning straw, which will pollute the environment.
