How to simply judge the quality of organic fertilizer?

Odor: Organic fertilizers derived from natural sources such as compost or manure may have a natural, earthy smell. If the fertilizer emits a foul or pungent odor, it could indicate poor quality or improper decomposition.

Texture and Consistency: High-quality organic fertilizers should have a consistent texture that is crumbly and well decomposed. Avoid fertilizers that are clumpy, contain large chunks, or appear unfinished in decomposition.

Color: The color of organic fertilizer can vary depending on the source materials used. Generally, well-composted organic fertilizers have a dark, rich color, indicating a high nutrient content. Lighter or inconsistent colors may suggest lower quality.

Presence of Foreign Materials: Check for any foreign materials or contaminants in the fertilizer, such as plastic pieces, rocks, or other debris. These can indicate poor manufacturing processes or inadequate quality control.

Certification: Look for organic fertilizers that carry certifications from recognized organic standards organizations. These certifications ensure that the product meets specific quality and purity standards.

Reputation and Reviews: Consider the reputation of the brand or manufacturer. Look for reviews or feedback from other users, either online or from trusted sources, to get an idea of their experiences with the organic fertilizer.
