How to tell real fertilizer from fake? Keep these methods in mind
As the saying goes: "Fool the land for a moment, and the land fools you for a year." Once farmers buy and use fake or inferior chemical fertilizers, the losses caused are hard to make up for, which both dampens farmers' enthusiasm and harms farmers' interests. Below are the common methods for identifying real and fake fertilizers: Visual inspection First look at the fertilizer packaging. The fertilizer packaging bag must indicate the product name, nutrient content (grade), trademark, net weight, standard code, factory name and address, contact phone number, production license number and fertilizer registration number, etc. If the above markings are absent or incomplete and the packaging is rather rough, it may be fake or inferior compound fertilizer. Pay special attention to fertilizers whose packaging bag seals show obvious signs of being opened; this phenomenon may indicate adulteration. In addition, pay attention to the production date on the production certificate inside the fertilizer bag. If fertilizer is stored for too long, the total nutrients will be lost. Second, look at the fertilizer's granule size (or crystalline state). High-quality fertilizer has relatively uniform granule size and specific gravity, a smooth surface, and is not prone to absorbing moisture or caking, while fake and inferior fertilizer is exactly the opposite, with uneven granule sizes, a rough surface, high moisture, and easy caking. Third, look at the fertilizer's color. High-quality fertilizer has very uniform color, with no obvious color difference, and the entire granule is uniform from the inside out. Most fake fertilizer, however, is colored on the surface and easily loses its color.

1. Choose the right herbicide variety; for unfamiliar varieties or ones not previously used locally, it is best to conduct a trial first. 2. Use safeners to prevent damage.
