Compound fertilizers generally have no odor. If there is odor, it is because the basic raw material nitrogen fertilizer mainly uses agricultural ammonium carbonate, or the basic raw material phosphate fertilizer contains toxic substance trichloroethane (acid). When trichloroacetaldehyde (acid) enters the farmland, it will cause burning of the seedlings, but the crops will not be harvested, and the toxic residue period will be long, which will affect the growth of the next season crop. Therefore, it is best for farmers' friends not to buy compound fertilizers with odors. The high-quality compound fertilizer has good water solubility, and most of the soaked in water can be dissolved, even if there is a small amount of sediment, it is fine. The inferior compound fertilizer is hardly soluble in water, and the residue is rough and hard. Because the market is relatively short of potash, the price is higher, and some unscrupulous manufacturers will crush the red brick and act as potash. At the time of purchase, the farmer friend can taste the red granules in a small amount, the potassium chloride is salty, and the red brick granules are not salty.
