Question: Could you talk about the current development status of liquid fertilizer in my country?
Zhang Chenglin: In some developed countries, liquid fertilizers have been widely used. Liquid fertilizers in the United States account for 55% of all fertilizer applications. Liquid fertilizers are also widely used in the United Kingdom, Australia, and France. In Israel, liquid fertilizers are applied almost 100% in the field. my country is a superpower in the production and consumption of fertilizers in the world, but most of the fertilizers produced and applied are solid fertilizers, and the proportion of liquid fertilizers is quite small. Liquid foliar fertilizer and fertilization are the main liquid fertilizer varieties in my country. The current liquid fertilizer market is faced with the dilemma that there is no unified industry standard, uneven quality, mixed products, and the output cannot be counted.

Q: Can liquid compound fertilizers and water-soluble fertilizers compare well?
Zhang Chenglin: Water and fertilizer integration is a method of fertilization that makes fertilizers work efficiently. It is suitable for all crops. More and more growers have realized that irrigation after the fertilizer is melted is better than direct application of granular fertilizer. However, farmers currently cannot use water-soluble compound fertilizers on the market, and only use them in small amounts on crops with high economic value. The market is in urgent need of fertilizers that are quick-dissolving, low-priced, and have good fertilizer efficiency. However, the standards set by the relevant departments are too high and too strict, so that although Chinese enterprises have the technology, they cannot produce water-soluble compound fertilizers that farmers can afford, and liquid compound fertilizers. Just fit this demand.

Q: What are the strengths and shortcomings of liquid compound fertilizer and granular compound fertilizer?
Zhang Chenglin: The liquid compound fertilizer is similar to the traditional granular compound fertilizer in its nutrient representation form, but the difference is in the following three points: 1. Liquid compound fertilizer is mixed with water to ensure safe concentration, without burning seedlings and roots; 2. Liquid compound The mixed fertilizer is used for a small amount of times, and it is generally not over-fertilized; 3. The liquid compound fertilizer contains more nutrients and organic matter, and the nutrients are more balanced. When applied correctly, the effect of liquid compound fertilizers is usually more than 30% higher than granular compound fertilizers. In addition, the liquid compound fertilizer has many advantages such as low production cost, no pollution, easy formulation adjustment, and simple quality inspection. The biggest disadvantage of liquid fertilizers is that they should not be transported over long distances. If packaging is required, the packaging cost is significantly higher than granular fertilizers. In order to save costs, some farmers adopt the method of mixing granular compound fertilizer with water. On the one hand, it is slow to dissolve. In addition, the core issues of scientific fertilization such as safe concentration, reasonable dosage, and nutrient balance are more difficult to grasp.
