1、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.

2、What Types of Fertilizers Are Considered High

High-potassium fertilizers, such as potassium nitrate, sulfate, chloride, dihydrogen phosphate, ammonium phosphate, and urea, are vital for replenishing potassium, enhancing disease resistance, stress tolerance, and crop yields.

3、Types and characteristics of potassium fertilizer

At present, there are many types of potassium fertilizers on the market, and each type of potassium fertilizer has different characteristics and scope of application.

4、Different Types And Usage Methods Of Potassium Fertilizers On The

Due to its ability to improve product quality and adapt to adverse external environments, potassium is known as a "quality element" and "stress resistant element". This article mainly explains the types of potassium fertilizers and their usage methods in the market.

11 High Potassium Fertilizers And When To Use Them

While some fertilizers rely on inorganic potassium, like potassium chloride or potassium nitrate, others take their potassium from biodegradable sources. Which fertilizer you choose depends on your garden’s needs and your own gardening principles.

Potassium Fertilizers

In this comprehensive guide, we’ll explore everything you need to know about potassium fertilizers, including their types, uses, application methods, and how to choose the right one for your garden or farm.

Potassium Fertilizer

Ammonium nitrate and calcium ammonium nitrates are especially suitable for many soil and climate conditions and water-soluble, urea-based fertilizers are also preferred for the same reasons [34]. Other frequently used fertilizers are phosphorus fertilizers.

Natural Potassium Fertilizers for Sustainable Agriculture

Natural potassium fertilizer (NPF) is a new concept for achieving the sustainability in modern agriculture system by the bioactivation of natural minerals by the potassium solubilizing microbes.

Potassium fertilizers are indispensable in agricultural production, playing a critical role in plant growth, development, and the yield and quality of crops. Under high-temperature conditions, the selection and application of potassium fertilizers become particularly important. High temperatures accelerate soil water evaporation and increase the mobility of potassium ions, which can affect the absorption and utilization efficiency of potassium. choosing the right type of potassium fertilizer for high-temperature environments is crucial to improving crop yields and quality.

1. Types of Potassium Fertilizers

1. Potassium Sulfate (K₂SO₄) This is a commonly used potassium fertilizer with a potassium content of 60%-70%. It is suitable for most crops and has high water solubility, making it easily absorbable by plants. due to its sulfur content, it may cause soil acidification over time. Thus, application rates should be carefully controlled.

2. Potassium Chloride (KCl) This chlorine-containing fertilizer has a potassium content of 50%-60%. Although its water solubility is lower than that of potassium sulfate, it can be improved with the addition of solubility enhancers. Potassium chloride has minimal impact on soil and is suitable for acidic soils or poorly drained areas.

3. Potassium Nitrate (KNO₃) A high-concentration potassium fertilizer with 60%-80% potassium content. It dissolves readily in water and is easily absorbed by plants. its nitrogen content may lead to excessive soil nitrogen, negatively impacting crop growth. Application rates must be controlled to avoid adverse effects.

4. Potassium Phosphate (KH₂PO₄) This phosphorus-containing fertilizer has a potassium content of 50%-60%. The phosphorus in potassium phosphate promotes photosynthesis and respiration in crops, enhancing growth speed and yield. Additionally, it improves soil structure and water-retention capacity.

2. Application of Potassium Fertilizers Under High Temperatures

1. Select Appropriate Fertilizer Types For high-temperature conditions, prioritize potassium sulfate or potassium chloride, as they have minimal soil impact and are efficiently absorbed. While potassium nitrate has high potassium content, its nitrogen component may cause soil nitrogen excess. Potassium phosphate, meanwhile, boosts crop growth via phosphorus but should be used based on specific needs.

2. Control Application Rates High temperatures reduce potassium absorption efficiency, so reduce dosages. A typical recommendation is 10-15 kg of potassium sulfate or potassium chloride per mu (approx. 667 m²).

3. Application Methods

   • Dissolve potassium fertilizers in water before use, as high temperatures accelerate dissolution.
   • Add solubility enhancers (e.g., sodium bicarbonate or sodium carbonate) to improve dissolution.
   • Combine potassium fertilizers with nitrogen or phosphorus fertilizers to prevent volatilization losses.

4. Timing of Fertilization Apply fertilizers during cooler periods (e.g., morning or evening) to minimize volatilization. Irrigate immediately after application to aid absorption.

5. Monitor Soil pH High temperatures may alter soil pH. For acidic soils, increase potassium sulfate or potassium chloride. For alkaline soils, prioritize potassium phosphate.

6. Combine with Other Fertilizers Use balanced NPK compound fertilizers to ensure nutrient availability while avoiding issues from single-nutrient overuse.

Under high-temperature conditions, selecting appropriate potassium fertilizers and controlling application rates are critical. Potassium sulfate and potassium chloride are preferred due to their low soil impact and high absorbability. While potassium nitrate is rich in potassium, its nitrogen content requires cautious use. Potassium phosphate enhances crop growth but should be applied judiciously. To optimize results, dissolve fertilizers thoroughly, apply during cool periods, and adjust formulations based on soil pH. Combining potassium fertilizers with nitrogen and phosphorus ensures comprehensive nutrient supply, maximizing crop productivity and quality.
