At present, the fertilizer market is flooded with numerous products labeled as "organic fertilizer." Prices vary significantly, ranging from a few hundred to several thousand yuan per ton. However, the quality of these products can be highly inconsistent, making it challenging for farmers to accurately assess their value just by looking at the packaging. As a result, many farmers are confused about what constitutes real organic fertilizer. Some believe that all organic fertilizers are similar and relatively inexpensive, while others mistakenly assume that higher prices equate to better quality. These misconceptions have created an opportunity for unscrupulous sellers to take advantage of the situation. So, is there a simple and effective way for farmers to distinguish genuine organic fertilizer from inferior products?
First, look carefully. Check the product label and the manufacturer’s information. Qualified organic fertilizers usually follow the NY-525 standard, which requires a total nutrient content (N + P₂O₅ + K₂O) of at least 5%, and a minimum of 10% organic matter. The label should clearly list the manufacturer’s name, address, and contact number. If these details are missing or unclear, it's a red flag.
Next, examine the physical appearance of the fertilizer. Organic fertilizers typically come in powder, granular, or pellet form. However, if you notice a lot of impurities inside the package, it may indicate poor quality. True organic fertilizers often have irregularly shaped particles due to the nature of the raw materials used. Be cautious of overly smooth granules, especially those that resemble compound fertilizers or urea. These might be made from industrial waste and may not provide the same benefits as those derived directly from organic sources.
Third, ask questions. Inquire about the raw materials used in the production of the fertilizer. High-quality organic fertilizers are often made from natural sources like soybean meal, bone meal, fish meal, or composted animal manure. On the other hand, fertilizers made from improperly processed industrial byproducts may contain harmful substances such as heavy metals, which can damage soil and crops over time.
Fourth, use your sense of smell. Take a handful of the fertilizer and sniff it. A strong, unpleasant odor may indicate that the product has not been properly decomposed or is even spoiled. Using such fertilizers could harm seedlings or introduce pathogens into the soil, leading to serious crop issues.
Finally, perform a simple dissolution test. Place a small amount of the fertilizer in a container of water and observe how quickly it dissolves. Genuine organic fertilizers should begin to form a paste within 10 minutes. If it doesn’t dissolve well or contains a lot of impurities, it may not be a high-quality product.
By following these simple steps, farmers can make more informed decisions when purchasing organic fertilizers, ensuring they get the best value and quality for their crops.
