1、The Residual Effect of Fertilizer

The accumulation of phosphorus and potassium is seldom relative so that fertilizer grade changes become necessary to maintain nutrient balance. Extremely high potassium levels lead to losses by leaching and luxury feeding, intensify magnesium deficiency, and eliminate response to sodium.

2、Environmental and economic benefits of substituting chemical potassium

In this study, we examine the effects of substituting straw for chemical K fertilizer on the emissions of greenhouse gas and pollutants and the associated direct and damage cost implications in China at the provincial level.

3、A Review of Potassium

Applying crop residues as soil amendments can provide essential crop nutrient inputs from organic sources while improving nutrient retention, soil health, water conservation, and crop performance.

Potassium Sulfate

Vines low in potassium are also more drought prone and less cold tolerant. When adequate, potassium favors grape quality by enhancing fruit coloration and sufficient acidity. However, excess potassium may raise juice pH undesirably and can potentially suppress magnesium uptake by the roots.

Potassium Fertiliser

Potassium fertilizer refers to substances like KCl or potassium sulphate used to provide essential potassium to plants for optimal growth. It should be placed strategically in the soil to ensure efficient absorption by plant roots.

Production of Potassium Sulfate through Valorization of Zero Liquid

High-purity potassium sulfate suitable for fertilizers is produced from lithium clay mining waste via fractional crystallization and metathesis reactions.

(PDF) Effects of Agricultural Potassium Fertilizer Application on Soil

This review examines the impact and regulatory mechanisms of potassium fertilizer on the soil carbon cycle, discussing how potassium fertilizer affects soil carbon storage and flow through...

Potassium sulfate fertilizer is a common chemical fertilizer primarily used to provide plants with the essential nutrient potassium. during its application, residue issues may occasionally arise. This phenomenon can be attributed to several factors:

1. Production Process Issues: Inadequate raw material processing or incomplete chemical reactions during the manufacturing of potassium sulfate fertilizer can result in unreacted chemicals remaining in the product. These residues may negatively impact soil and crops, such as reducing fertilizer efficacy or causing plant diseases.

2. Improper Storage Conditions: Exposure to environmental factors like temperature, humidity, and light during storage can alter the composition of potassium sulfate fertilizer, leading to residue formation. Additionally, poor sealing of storage containers might allow oxygen to react with the fertilizer, producing residues.

3. Inappropriate Fertilization Methods: Overapplication or improper use of potassium sulfate fertilizer can also generate residues. For example, excessive use leads to salt accumulation in the soil, affecting its air permeability and water retention capacity, which in turn harms crop growth. Improper application may cause chemical components in the fertilizer to react with other substances in the soil, forming residues.

4. Soil Condition Influences: Factors such as soil pH, structure, and organic matter content affect the effectiveness of potassium sulfate fertilizer. Unsuitable soil conditions for the fertilizer can lead to residue formation. For instance, in acidic soils, sulfate ions combine with potassium ions to form potassium sulfate precipitates, creating residues.

5. Crop Varieties Differences: Different crops have varying abilities to absorb potassium sulfate fertilizer and require different amounts. If a crop has a high demand for the fertilizer but is over-fertilized or improperly fertilized, it can result in residue production.

To minimize residue formation from potassium sulfate fertilizer, consider the following measures:

1. Choose high-quality potassium sulfate fertilizer products and ensure they meet quality standards during production.
2. Apply the fertilizer strictly according to recommended dosages to avoid overuse.
3. Test the soil before applying potassium sulfate fertilizer to understand its pH, structure, and organic matter content, enabling appropriate fertilization.
4. Monitor crop growth during fertilization and adjust the fertilization plan promptly if any abnormalities occur.
5. For specific crops or soil conditions, adopt suitable fertilization techniques such as deep placement or furrow application to enhance fertilizer utilization efficiency and reduce residue formation.

residue formation from potassium sulfate fertilizer is a complex process influenced by multiple factors, including production processes, storage conditions, fertilization methods, and soil characteristics. Reducing residue formation requires a comprehensive approach addressing various aspects. strengthening the regulation of potassium sulfate fertilizer products to ensure their quality is crucial for providing safe and efficient fertilizers for agricultural production.
