1、Soil potassium regulation by changes in potassium balance and iron and

Southern China’s paddy soils are poor in potassium (K) and rich in iron (Fe) and aluminum (Al) oxides, both of which are affected by fertilizer application. However, the response of soil K budget to long-term K fertilization and Fe and Al oxides remains unclear, especially in the subsurface horizons in different soil types.

2、Natural Potassium Fertilizers for Sustainable Agriculture

There are no K-bearing minerals suitable for the manufacturing of traditional K fertilizers in India, China, or Africa. As a result, K-fertilizers are imported in their whole. Potassium bio-fertilizers may be a feasible alternative for sustaining crop output and preserving soil fertility.

3、Potash Fertilizers: Types, Benefits, And Uses In Agriculture

Fertilizers with potassium vary in composition, solubility, and secondary nutrient content, which means different choices suitable for different fertilization strategies.

4、Potassium Fertiliser

Potassium fertilizer is defined as a type of chemical fertilizer, commonly in the form of potassium chloride and potassium sulfate, that aids in the transference of food materials within plants, enhances leaf greenness, and increases grain plumpness.

Potassium supply in agriculture through biological potassium fertilizer

Biological potassium fertilizer (BPF) is a promising technology to improve potassium availability in the soil through the bio-activation of endogenous K-reserves.

10 Potassium Fertilizers: MOP, SOP, KNO3, MKP, Potassium Humate

Selecting the right potassium fertilizer depends on crop needs, soil conditions, and economic considerations. While KCl is the most economical choice, alternatives like SOP, KNO₃, and organic sources provide specialized benefits for sustainable agriculture.

Potassium Sulphate: Vital for Fertilizer Blends in Asia & Africa

Potassium sulphate (K₂SO₄) is a water-soluble fertilizer component widely used to enrich soil potassium content without adding chloride. Its inclusion in fertilizer blends enhances crop yield, strengthens plant resistance, and supports sustainable farming practices across Asia and Africa.

Potassium Sulfate

Potassium (K) fertilizer is commonly added to improve the yield and quality of plants growing in soils that are lacking an adequate supply of this essential nutrient. Most fertilizer K comes from ancient salt deposits located throughout the world.

Potassium Fertilizers for Crop Production

Potassium is one of three macronutrients essential for plant growth. Learn which fertilizers have high potassium and how to measure and apply it for agriculture production.

Different Types And Usage Methods Of Potassium Fertilizers On The

Common potassium fertilizers in the market include potassium chloride, potassium nitrate, potassium sulfate, etc. Below is an introduction to their respective characteristics, application methods, precautions, etc.

Potassium sulfide fertilizer is a commonly used chemical fertilizer primarily designed to replenish sulfur in the soil, thereby enhancing crop yield and quality. It is particularly effective in the following types of farmland:

1. Dry Land: Potassium sulfide fertilizer contains sulfur, which can effectively improve soil pH and increase fertility. Additionally, sulfur promotes crop growth and enhances disease resistance. When used in dry land agriculture, this fertilizer significantly boosts crop yield and quality.

2. Paddy Fields: In paddy fields, potassium sulfide fertilizer plays a critical role by providing sulfur to aid nutrient absorption, thus increasing crop productivity. it reduces sulfide content in water, preventing eutrophication and protecting water resources.

3. Saline-Alkali Soil: Soils with high salt content and elevated pH (alkaline conditions) often have low fertility, leading to poor crop growth and yield. Applying potassium sulfide fertilizer helps lower soil salinity and pH, while improving fertility and promoting healthy crop development.

4. Acid Soil: Soils with a pH below 5.5 lack essential nutrients, hindering crop growth. Potassium sulfide fertilizer supplements sulfur, enhances soil fertility, and supports robust crop growth.

5. Soils Lacking Organic Matter: Organic matter is vital for nutrient supply, microbial activity, and soil health. In fields with depleted organic matter, potassium sulfide fertilizer provides sulfur to improve fertility and stimulate crop growth.

6. Heavy Metal-Contaminated Soil: Farmland polluted with heavy metals (e.g., lead, mercury) faces severe crop growth challenges. Potassium sulfide fertilizer introduces sulfur, which binds with heavy metals to form stable compounds, reducing their availability and safeguarding crop safety.

potassium sulfide fertilizer is a versatile tool applicable to diverse soil types. Its rational use can improve crop productivity, enhance soil health, protect water resources, and contribute to sustainable agricultural ecosystems.
