In modern agriculture, scientific fertilization is key to achieving high yields, superior quality, and sustainable development. NPK 20-20-20 water soluble fertilizer, with its balanced ratio of nitrogen (N), phosphorus (P), and potassium (K) (20% each) and chelated trace elements (TE), has become a top choice for growers worldwide. It not only meets the nutritional needs of crops throughout their growth cycle but also enables precision management through fertigation systems, significantly improving resource efficiency.

In modern agriculture, fertilizer selection directly impacts crop yield and quality. Among the various products, "compound fertilizer" and "bulk blending fertilizer" are two common types, but their differences are often overlooked. This article analyzes their definitions, production processes and nutrient characteristics to help you choose wisely.

Water soluble fertilizer, abbreviated as WSF, is a multi-component compound fertilizer that can be completely dissolved in water. It can quickly dissolve in water and is easily absorbed by crops, with a relatively high absorption and utilization rate. Water soluble fertilizers are suitable for various purposes such as irrigation and fertilization, foliar fertilization, soilless cultivation, soaking seeds and roots, etc. Especially in facility agriculture, they are combined with micro sprinkler irrigation, drip irrigation, etc. to achieve the integration of water and fertilizer, and achieve the efficiency of saving water, fertilizer and labor.

Ammonium sulphate is an inorganic compound with the chemical formula (NH4) 2SO4. It appears as white crystals or granules and has no odor. It will be decomposed above 280 ℃, producing gases such as ammonia and sulfur dioxide. Ammonium sulfate is easily soluble in water, with a solubility of 70.6g at 0 ℃ and 103.8g at 100 ℃. Ammonium sulfate is insoluble in ethanol and acetone.
