1. Fertilizers containing harmful ions Ammonium chloride, potassium chloride and other chemical fertilizers contain chloride ions, which, when applied to the soil, produce water-soluble chlorides, which are detrimental to seed germination and seedling growth. Fertilizers such as ammonium nitrate and potassium nitrate contain nitrate ions and should not be used as seed fertilizer. 2. Fertilizer ammonium bicarbonate, which has a corrosive effect on seeds, is corrosive and volatile. Superphosphate contains free sulfuric acid and phosphoric acid, both of which have strong corrosive effects on seeds. If it is necessary to use as a seed fertilizer, contact with the seed should be avoided. Ammonium bicarbonate can be applied under the seeding ditch or separated from the seed by a certain soil layer, or mixed with superphosphate and soil fertilizer. 3. Fertilizer urea which is toxic to seeds often produces a small amount of biuret in the production process. When the content exceeds 2%, it will cause toxicity to seeds and seedlings.
