1、Plant Production and Protection Division: Fertilizer Specifications

Fertilizer grade is an expression referring to the legal guarantee of the available plant nutrients expressed as a percentage by weight in a fertilizer, e.g. a 12-32-16 grade of NPK complex fertilizer indicates the presence of 12 % nitrogen (N), 32 % phosphorous (P 2 O 5) and 16 % potash (K 2 O).

2、NPK 17

Enhance your crop growth with NPK 17-17-17 (SOP), a balanced fertilizer providing equal proportions of Nitrogen, Phosphorus, and Potassium, enriched with Sulfate of Potash (SOP). This formulation supports comprehensive plant nutrition, promotes robust growth, and improves soil fertility.

3、Nutrient Content of Fertilizer Materials

Nutrient Content of Fertilizer Materials eference guides to fertilizer materials. These materials may be used alone or blended with other fertilizer mate ials to form a multinutrient fertilizer. The actual nutrient content may vary from what is lis ther materials blended with the product. Most values are for the fertilizer-

Potassium Sulphate (SOP) N:P:K 00:00:50 ( Granular)

This is fully water soluble, virtually chlorine free fertilizer which can be used on any crop. It contains a minimum of 50 % Potassium as K2O and Sulphur 17-18%.

Sulfate of potash fertilizer granular and powder 0

100% water soluble sulfate of potash fertilizer contains 50% Potassium and 18% Sulfur for tobacco and fruits and vegetables.

NPK Fertilizer Guide: Chloride vs Sulfate vs Nitrate Types

This guide provides a clear and practical explanation of different NPK fertilizer types, focusing on chloride-based, sulfate-based, and nitrate-sulfate formulations, along with guidance on how to choose the most suitable option for specific crops and soil conditions.

SULFATE OF POTASH

Sulfate of Potash Granular is a 0-0-50 white granule that provides 50% potash and 17% sulfur to crops. This potassium sulfate fertilizer is chloride-free and has a low salt index, less than half that of muriate of potash.

Sulfate of Potash Granular All

Because of its high concentration of potassium, Sulfate of Potash helps plants utilize nitrogen more efficiently while, at the same time, balancing the effect of excess nitrogen and calcium. The use of Sulfate of Potash may also reduce boron requirements.

NPK Compound Fertilisers

NP (K) materials are obtained through the nitrophosphate process. Rock phosphate is processed with nitric acid and large amounts of a co-product, such as calcium nitrate or calcium ammonium nitrate, are co-produced. The resulting NP (K) formulations are complex fertilisers.

Sulfate of Potash Fertilizer: Enhance Plant Growth & Crop Yields

It typically contains around 50% potassium (K 2 O equivalent), which makes it an attractive concentrated source of this essential nutrient. This high concentration ensures that plants receive an ample supply of potassium, which is crucial for their overall growth and development.

Sulfate of potash compound fertilizer is a composite fertilizer containing sulfate of potash, typically comprising two or more nutritional elements. The nutrient content of sulfate of potash compound fertilizer varies depending on brand, specifications, and intended use, but generally ranges between 30% and 60%.

The primary function of sulfate of potash compound fertilizer is to provide essential nutrients such as nitrogen, phosphorus, and potassium required for plant growth. Among these, sulfate of potash serves as an important source of potassium, which promotes robust root development, enhances crop disease resistance, and increases yield. Additionally, sulfate of potash helps regulate water balance within plants, improving their drought tolerance.

The application method for sulfate of potash compound fertilizer is relatively straightforward. First, determine the appropriate amount of fertilizer based on soil fertility and crop requirements. Generally, applying 5-10 kilograms per mu (approx. 0.0667 hectares) is sufficient. Next, evenly spread the fertilizer over the soil surface and incorporate it into the soil using a hoe to ensure thorough mixing. Finally, timely top-dressing should be performed according to the crop's growth stage and weather conditions.

It is important to note that while sulfate of potash compound fertilizer is convenient to use, several considerations must be taken into account:

1. Proper Dosage: Over-application can lead to resource waste and potential harm to crops, whereas insufficient application may hinder growth and reduce yields. dosage should be determined based on soil fertility and crop needs.

2. Timely Application: Generally, sulfate of potash compound fertilizer should be applied during the early stages of crop growth and peak periods to maximize nutrient effectiveness.

3. Scientific Application Method: Ensure even distribution by spreading the fertilizer uniformly across the soil surface before incorporation. This practice prevents localized over-fertilization or deficiencies.

4. Irrigation After Application: Watering immediately after fertilization aids in dissolving the nutrients, enhancing their availability to plants.

5. Safety Precautions: When handling sulfate of potash compound fertilizer, personal protective equipment should be worn to avoid skin and eye contact. Store the fertilizer away from heat sources and high temperatures to prevent hazards.

sulfate of potash compound fertilizer is a commonly used agricultural input that effectively supplies essential nutrients for healthy plant development and improved crop productivity. careful attention to dosage, timing, and application methods is crucial to ensure optimal utilization and promote sustainable agricultural practices.
