要辨别复合肥料的真伪，首要从其外部包装、标识和图案入手。 正规厂家生产的复合肥料，包装通常做工精细，字迹清晰且信息完备。 重要的是，包装上需明确列示生产厂商的名称、地址、联系方式、生产日期及有效成分含量等信息。 因此，务必选择合规的采购途径，如官方认证的经销商或信誉良好的农民合作社，切忌因小便宜而购买无名产品。 除了仔细审查包装外，通过复合肥料的物理特性进行进一步检验也是一种有效的方法。 一般而言，正品复合肥料不会散发出刺鼻的异味，并且具有较好的溶解性，溶解后的液体应为清澈透明，且无残渣。 如对某种复合肥料存在疑虑，可取少量样品与水混合，观察其溶解情况和溶液的透明度，这将作为初步的判断依据。 有效防止假 …

4、How do you tell the difference between true and false fertilizers

How to distinguish the true and false of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, diammonium phosphate, compound fertilizer, organic fertilizer, microbial fertilizer and water soluble fertilizer.

How to identify genuine and fake fertilizers?

Check the sealing of the packaging bag: pay special attention to fertilizers with obvious signs of unsealing on the packaging seal. This phenomenon may be adulterated.

4 ways to identify true and false fertilizers

In order to reduce the losses caused by fake fertilizers, several methods for identifying fake fertilizers are introduced. 1, look at the appearance: (1) look at the packaging.

True and fake fertilizer identification and reasonable use

According to relevant national regulations, chemical fertilizer packaging bags must be marked with the product name, nutrient content, grade, trademark, net weight, standard code, factory name, site, production license number, etc.; if the above-mentioned mark is not complete or incomplete, it may be false. Fertilizer or poor fertilizer.

How to identify true and false fertilizers

How to identify true and false fertilizers The method of simply identifying the authenticity of fertilizers is summarized as five words: “look, touch, smell, burn, and wet†. First, look at : (1) Fertilizer packaging. Fertilizers produced by regular manufacturers are standardized and strong.

How to Identify the True or False of Compound Fertilizer?

In order to buy fertilizers of high quality and low price, farmers should have a certain knowledge of fertilizer identification, and understand laws and regulations to reduce unnecessary economic losses. Identification of genuine and fake fertilizers should proceed from four aspects:

Authentic compound fertilizer brands from large manufacturers (how to

However, for farmers, if they don't distinguish carefully, it is easy to buy fakes. Two years ago, a type of fertilizer like this was exposed, which harmed many farmers. This type of fertilizer is the same fertilizer no matter what kind of fertilizer you buy, but the packaging bag is changed.

In agricultural production, selecting the right fertilizer is crucial for improving crop yields and quality. the variety of potassium fertilizers on the market can make it difficult to distinguish authentic products from fake ones, causing confusion for farmers. To help everyone identify genuine potassium fertilizers, this article introduces some practical methods and techniques.

1. Visual Inspection Method

• Appearance: Authentic potassium fertilizers are typically dark brown or black granular particles with a smooth surface and no odor. If the fertilizer has an unusually light color or a pungent smell, it may be counterfeit.
• Packaging: Genuine products will have clear production dates, expiration dates, and usage instructions on the packaging. Fake products may have blurred or missing information.

2. Density Test Method

• Water Test: Place a small amount of fertilizer in water. Authentic potassium fertilizers will sink rapidly, while fake ones may float or sink slowly.
• Hydrometer Test: Use a hydrometer to measure the density. Authentic potassium fertilizers have a density close to that of pure water, while fake ones may differ significantly.

3. Solubility Test Method

• Dissolution Rate: Add fertilizer to water and observe its dissolution speed. Authentic potassium fertilizers dissolve quickly and form a clear solution, while fake ones may dissolve slowly or not at all.
• Chemical Strip Test: Use test strips to detect potassium ion content. Authentic fertilizers will trigger a noticeable reaction, while fake ones may show no or weak reactions.

4. Chemical Composition Analysis

• Lab Testing: Analyze the chemical components (e.g., potassium, nitrogen, phosphorus) in the fertilizer. Authentic products typically have a high potassium content, while fake ones may lack essential elements or contain impurities.
• Soil Test Kits: Use specialized kits to measure potassium content through colorimetric methods.

5. Price Comparison Method

• Market Research: Compare prices of fertilizers of the same specifications and brands. Significant price differences may indicate quality issues.
• Avoid Low-Cost Traps: Be wary of counterfeit products sold at unusually low prices.

6. Brand Reputation

• Trusted Brands: Choose fertilizers from well-known brands with strict quality control and reliable after-sales service.
• Research Credibility: Verify manufacturer qualifications and customer reviews to assess brand reliability.

7. Anti-Counterfeit Features

• Check Security Marks: Look for official anti-counterfeit measures, such as QR codes or tamper-evident labels.
• Verify Online: Use official websites to authenticate security codes and ensure product legitimacy.

8. Sensory Experience Method

• Odor: Authentic potassium fertilizers have a faint, natural scent, while fake ones may release harsh chemical odors.
• Texture: Genuine products feel fine and smooth, while fake ones may be coarse or contain impurities.

9. Professional Laboratory Testing

• Seek Expert Help: If unsure, consult agricultural extension departments or professional testing institutions. They use advanced equipment to provide accurate results.

10. Precautions

• Check Packaging: Ensure the packaging is intact, with no damage or leaks.
• Buy from Reliable Sources: Avoid purchasing from unknown vendors. Stick to authorized channels for quality assurance.
• Follow Instructions: Apply according to guidelines to prevent overuse, which can lead to soil salinization.

identifying authentic potassium fertilizers requires combining multiple methods, prioritizing brand reliability, and trusting sensory judgment. Always follow scientific principles to ensure healthy crop growth.
