1. Fertilizers that are corrosive to seeds should be avoided when used as seed fertilizers. Ammonium bicarbonate, for example, is both corrosive and volatile. It contains free sulfuric acid and carbonic acid, which can react with calcium phosphate in the soil. These acids have a strong corrosive effect on seeds, potentially damaging them and reducing germination rates. Therefore, it is not recommended to apply ammonium bicarbonate directly to seeds. If its use is unavoidable, it should be placed separately from the seeds. One effective method is to apply it below the seed furrow, with a layer of soil between the fertilizer and the seed. Alternatively, it can be mixed with superphosphate or blended with organic manure to dilute its concentration and reduce the risk of damage. 2. Fertilizers containing chloride ions, such as potassium chloride and ammonium chloride, should not be used as seed fertilizers. When these materials are applied to the soil, they release water-soluble chlorides, which can negatively affect seed germination and early seedling development. Chloride ions can interfere with the uptake of essential nutrients by the roots, leading to stunted growth or even plant death in sensitive crops. Similarly, fertilizers like potassium nitrate contain nitrates, which, while beneficial in moderate amounts, can also be harmful if applied directly to seeds. It's important to choose the right type of fertilizer based on the crop and growing conditions to ensure healthy plant development and maximize yield.
