Potassium chloride total nutrients ≥57% Minmetals Salt Lake 50KG/bag

This product is a standardized agricultural potassium chloride fertilizer produced by Minmetals Salt Lake Co., Ltd. Leveraging the abundant potassium salt resources of Qinghai Chaerhan Salt Lake, "Minmetals Salt Lake" is one of China’s key potassium fertilizer production bases, with obvious advantages in resource guarantee and large-scale production. The product adopts a standard packaging of 50kg/bag, which conforms to the mainstream specifications of domestic agricultural input circulation and is convenient for warehousing, transportation, and measurement. The total nutrients ≥ 57% marked on the package refers to the minimum guaranteed content of plant-available potassium (calculated as potassium oxide K₂O), which meets the requirements of national qualified or first-class product standards for agricultural potassium chloride.

1. Core Components and Product Form

Main Component: The main component of this product is potassium chloride. Nutrients exist mainly in the form of potassium ions and chloride ions.

Nutrient Concentration: Total nutrients (K₂O) ≥ 57%, belonging to medium-high concentration commercial potassium fertilizer, which can effectively meet the large demand for potassium by crops.

Physical Form: The product is usually white or light red crystals or granules (specific color depends on associated minerals and processes). It has a uniform form, good fluidity, and certain anti-caking properties, facilitating mechanical or manual spreading.

2. Core Efficacy: Agronomic Effects of Potassium

As a basic potassium fertilizer, its core value lies in providing essential potassium nutrition for crops, with main effects including:

Enhancing Stress Resistance: Improves crop stem strength and significantly enhances resistance to adverse conditions such as lodging, drought, diseases, and low temperatures.

Improving Quality and Increasing Yield: Promotes the synthesis and transportation of photosynthetic products, and plays a key role in increasing fruit sugar content, color, taste, as well as improving grain thousand-grain weight and root-tuber starch content.

Regulating Physiological Metabolism: Participates in various physiological processes such as water regulation, enzyme activation, and nutrient transport in plants.

3. Key Characteristics: Impact of Chloride Ions and Scientific Application

This product contains approximately 45% chloride ions, a characteristic that determines its targeted use:

Suitable Crops (Chlorine-Tolerant or Chlorine-Loving Crops)

Most Ideal: Particularly suitable for field crops such as rice, cotton, wheat, corn, and sorghum. Chlorine has a positive effect on nutrient absorption and disease resistance of some of these crops (e.g., rice).

Economical and Efficient: Using it on the above crops is the most cost-effective potassium nutrition supplement solution.

Crops for Cautious Use or Prohibition

Strictly Avoid: Prohibited for "chlorine-intolerant crops" sensitive to chloride ions, such as tobacco, potatoes, sweet potatoes, citrus, grapes, tea trees, melons, and some legumes.

Risks: Chloride ions will seriously affect the quality of these crops, such as impairing the combustibility of tobacco, reducing the starch content of tubers, and increasing fruit acidity while decreasing sweetness.

Application and Soil Precautions

Priority for Well-Drained Plots: Under conditions of abundant rainfall or irrigation, chloride ions can be leached, making it difficult to accumulate and cause salt damage.

Cautious Use in Saline-Alkali Soils, Arid Regions, and Protected Agriculture: In these environments, chloride ions tend to accumulate in the root zone, aggravating soil salinization and potentially burning crop roots.

Recommended as Base Fertilizer or Early Topdressing for Deep Application: Apply and plow into the soil in advance to help chloride ions migrate to the lower soil layer, reducing salt stress on seedlings.
