3、Potassium Chloride

Potassium chloride, also called muriate of potash, is a naturally occurring ore formed from the evaporation of ancient seabeds and is the most widely used potassium fertilizer in the World, accounting for about 90% of total consumption of potassium-containing fertilizers.

NY/T 1977

This standard specifies test methods for determination of total nitrogen, phosphorus and potassium content in water-soluble fertilizers. This standard is applicable to determination of total nitrogen, phosphorus and potassium content in liquid or solid water-soluble fertilizers.

Introduction to Compound Water

Composition: Compound water-soluble NPK fertilizer is a comprehensive fertilizer, typically containing three main nutrients: nitrogen (N), phosphorus (P), and potassium (K).

Fertilizers. Determination of the water

BS EN 15477 is a standard that serves technical specifications for water-soluble potassium content in fertilizers, enabling nutrient uptake in plants and prevention of potassium deficiency that stunts plant growth and reduces crop yields in agricultural applications.

Water-soluble fertilizers, also known as liquid fertilizers, are liquid formulations that use water as a solvent. They typically contain multiple nutrients, including nitrogen (N), phosphorus (P), potassium (K), as well as microelements and secondary macroelements. The key advantage of water-soluble fertilizers lies in their complete solubility in water, enabling convenient application and rapid absorption by crops.

The maximum potassium content in water-soluble fertilizers depends on specific product formulations and manufacturing processes. Generally, potassium levels range from 20% to 50% or even higher. For instance, high-potassium water-soluble fertilizers may contain 40%–50% potassium, while low-potassium variants offer reduced levels but still meet most crops' growth requirements.

When selecting water-soluble fertilizers, consider the following factors:

1. Crop Type: Different crops have varying potassium needs. Fruits and vegetables often require higher potassium, whereas grain crops need less. Choose fertilizers tailored to the crop species.

2. Soil Type: Soil pH, organic matter content, and other factors influence potassium uptake. Adjust fertilizer selection based on soil conditions to ensure effective absorption.

3. Application Method: Foliar spraying allows for quicker potassium absorption compared to root application, which may be affected by soil adsorption.

4. Timing and Frequency: Optimal timing and frequency enhance potassium utilization. Early-stage application promotes root development, improving absorption capacity.

5. Brand and Quality: Reputable brands with reliable quality ensure consistent results. Check labels for ingredient details, concentrations, usage instructions, and shelf life.

water-soluble fertilizers can achieve potassium contents exceeding 50%. To optimize nutrient delivery, combine crop type, soil conditions, application methods, and brand reliability. Avoid over-application to prevent soil salinization or nutrient imbalances.
