Formulation and Preparation Method of Water-Soluble Fertilizer

  Water-soluble fertilizers, as indispensable high-efficiency fertilizers in modern agriculture, play a vital role in crop growth due to their characteristics of easy dissolution in water, rapid absorption, and high utilization rates. This article will provide a detailed overview of the formulation design, raw material selection, production methods, and usage precautions for water-soluble fertilizers, helping farmers better understand and apply this highly effective fertilizer.

  The formulation of water-soluble fertilizers must be scientifically designed according to different growth stages and nutritional requirements of crops. Generally, water-soluble fertilizer formulations contain major nutrients such as nitrogen, phosphorus, and potassium, along with trace elements like calcium, magnesium, zinc, and boron to meet comprehensive crop growth needs. Below is an example of a typical water-soluble fertilizer formulation:
Total Nitrogen Content: 20%
Nitrate nitrogen: 3.4%
Ammonium nitrogen: 1.4%
Urea nitrogen: 15.2%
Water-soluble phosphorus: 20%
Soluble potassium: 20%
EDTA iron: 0.1%
EDTA manganese: 0.05%
EDTA Zinc: 0.05%
EDTA Copper: 0.05%
Boron: 0.05%
Molybdenum: 0.0005%
Magnesium: 0.46%
  This formulation features a 1:1:1 NPK ratio, suitable for the growth requirements of most crops. Additionally, the inclusion of multiple trace and microelements helps enhance crop stress tolerance and quality.
