Its main characteristics are low dosage, convenient use, low usage cost, fast crop absorption, and extremely high nutrient utilization rate. In this way, people can completely design formulas based on the nutritional requirements required for crop growth. Scientific formulas will not cause fertilizer waste, making their fertilizer utilization rate about 2-3 times that of conventional compound chemical fertilizers (in China, the fertilizer utilization rate of ordinary compound fertilizers is only 30% -40%). Secondly, water-soluble fertilizers are quick acting fertilizers, allowing growers to quickly see the effectiveness and performance of fertilizers, The fertilizer formula can be adjusted at any time according to different crop growth trends.
