Which fertilizers can't be used as fertilizers?

Which fertilizers can't be used as fertilizers? What is the reason? Also ask the netizens who know to help introduce that seed fertilizer is a way of fertilization that is mixed with seeds or applied near seeds and provides nutrients at the seedling stage of crops. But not all kinds of fertilizers are suitable for growing fertilizer. Because some farming network has sorted out some fertilizers that can not be used as a kind of fertilizer, the following are listed in detail for netizens' reference. First, ammonium bicarbonate should not be used as seed fertilizer, because the ammonia gas produced during the decomposition of ammonium bicarbonate will affect seed germination and lead to uneven seedling emergence. Second, ammonium nitrate should not be used as seed fertilizer. Because ammonium nitrate has strong hygroscopicity, it can be liquefied if the air is moist, or it may stick to the seeds and affect the seed germination. Third, ammonium chloride and potassium chloride are not suitable to be used as seed fertilizer, because these two fertilizers contain a lot of chloride ion, when the concentration of local chloride ion in the soil is too high, it can inhibit seed germination and can not be used as seed fertilizer. If seed fertilizer is urgently needed in production, and there is no ideal variety of fertilizer, the principles of separating seeds from fertilizer and strictly controlling the amount of fertilizer must be grasped. Some experiments have been summarized in the seed network, but the nitrogen fertilizers with strong volatility, strong hygroscopicity and harmful ingredients can not or should not be used as seed fertilizer, otherwise it will affect seed germination and seedling growth. What is microbial fertilizer and what is potassium magnesium sulfate fertilizer?
