With the popularization of global agricultural precision management, correctly mastering the compound fertilizer to water ratio has become the key to improving fertilization efficiency. Domestic and foreign agricultural institutions jointly issued the "Guidelines for the Application of Water-soluble Compound Fertilizers" to provide farmers with authoritative operating standards, which has attracted widespread attention in the industry.

Why pay attention to the water ratio?

Too high a concentration of compound fertilizer can easily cause crop root burns and soil compaction, while too low a concentration will affect fertilizer efficiency. Studies have shown that scientific dilution can increase fertilizer utilization by more than 30%. The recommended water ratio for mainstream compound fertilizers is 1:100 to 1:200 (that is, 1 kg of fertilizer is mixed with 100-200 liters of water), which needs to be adjusted according to crop type, growth period and climate.

International general operation suggestions

Vegetables (tomatoes, cucumbers, etc.): 1:200 in the seedling stage, 1:150 in the fruiting stage

Fruit trees (citrus, apples, etc.): 1:180 in the growth stage, 1:120 in the fruiting stage

Flowers: sensitive flowers or seedlings 1:1500, fertilizer-loving plants 1:900

Precautions

1. Soft water is preferred for dilution, and chelating agents are recommended for hard water areas

2. Prepare and use immediately, and let stand for no more than 4 hours

3. The drip irrigation system needs to filter undissolved particles to avoid blockage

4. When choosing fast-acting water-soluble compound fertilizer, apply it around the roots of the crop, and evenly apply it to promote better distribution of nutrients.

American agricultural expert Dr. Smith reminds: "The nitrogen, phosphorus and potassium ratios of different brands of compound fertilizers vary greatly, and must be operated according to the product instructions."
