1、Harmful Effects of Excessive Potassium Fertilizer on Yang Mei

This paper reviews the applications of common potassium-containing materials, explores the effects and mechanisms of nano-fertilizers on plants, and offers insights into future applications of nano-potassium fertilizers in agriculture.

2、The potassium paradox: Implications for soil fertility, crop production

Contrary to the inculcated perception of KCl as a qualitative commodity, more than 1400 field trials predominately documented a detrimental effect of this fertilizer on the quality of major food, feed and fiber crops, with serious implications for soil productivity and human health.

3、Over

Excessive and unchecked use of fertilizers, known as overfertilization, has emerged as a grave concern for both the environment and human health. This article discusses about the negative impacts of overfertilization and explore potential solutions to mitigate its effects.

4、Impact of Overfertilization on Plant Health and Nutrition

While fertilizers provide essential nutrients for plant growth, excessive application can lead to detrimental effects on plant health, soil quality, and the environment.

5、Chemical Fertilizers and Their Impact on Soil Health

Constant use of chemical fertilizer can alter the pH of soil, increase pests, acidification, and soil crust, which results in decreasing organic matter load, humus load, useful organisms, stunting plant growth, and even become responsible for the emission of greenhouse gases.

Optimizing potassium and nitrogen fertilizer strategies to mitigate

Considerable research has been dedicated to GHG mitigation through reduced NF application. However, there has been comparatively less attention given to the consequences of optimizing the application of both nitrogen and potassium fertilizers (KF) (Feng et al., 2016; Recio et al., 2019).

Effect of Different Potassium Fertilizer Application Rates on the Yield

Potassium (K) is crucial for global maize (Zea mays L.) production, yet the issue of “high K fertilizer input but low utilization efficiency” in K-rich soils of Xinjiang remains underexplored. A three-year field experiment (2020, 2021, 2024) in Xinjiang evaluated the effects of reduced K application on maize growth, grain yield (GY), and K-use efficiency. Five treatments were tested: K100 ...

Excessive application of chemical fertilizer and organophosphorus

It is significant to clarify the factors influencing TP loss, as well as explore the relationship between TP loss from planting and surface water eutrophication for making recommendations on the reduction of environmental pollution.

Potential Harms of Excessive Potassium Fertilizer on Plants

This article explores the impact of excessive potassium levels on plants, the underlying mechanisms, symptoms of toxicity, and management strategies to prevent or mitigate its negative consequences.

ADVERSE EFFECTS OF CHEMICAL FERTILIZERS AND PESTICIDES ON HUMAN HEALTH

Foods grown with chemical fertilizers caused various deteriorating health hazards in animals as well as human beings. The following are some of the effects: Residues of pesticides and herbicides affect the central nervous system, respiratory and gastro intestinal system of human beings.

Potassium chloride fertilizer is a common chemical fertilizer widely used in agricultural production. excessive use of potassium chloride fertilizer may pose certain hazards to soil and the environment. The following are some potential consequences:

1. Soil Salinization: Excessive use of potassium chloride fertilizer can increase the salt content in soil, leading to salinization. Salinization disrupts soil structure and functionality, affecting crop growth and yield. Additionally, it may cause groundwater tables to rise, triggering secondary soil alkalinization issues.

2. Soil pH Imbalance: Overuse of potassium chloride fertilizer may lead to soil pH imbalance. As an acidic fertilizer, excessive potassium chloride can acidify the soil, hindering normal crop growth. pH imbalances can disrupt soil microbial communities, reducing soil fertility and ecological balance.

3. Soil Structure Degradation: Excessive potassium chloride application can degrade soil structure. Since potassium chloride is not easily decomposed in soil, long-term accumulation forms crystalline deposits, reducing soil porosity, aeration, and water permeability. This impairs root respiration and nutrient absorption in crops.

4. Reduced Soil Biodiversity: Overuse of potassium chloride may decrease soil biodiversity. As a non-selective fertilizer with slow nutrient release, it may prevent beneficial microorganisms from accessing nutrients promptly, affecting their reproduction and survival. This disrupts soil microbial communities, undermining soil fertility and ecosystem stability.

5. Water Pollution: Excessive potassium chloride use can contaminate water bodies. Since potassium chloride is resistant to degradation, excessive runoff into rivers and lakes contributes to eutrophication, harming aquatic life. Additionally, reactions between potassium chloride and organic matter in water can produce toxic substances, worsening pollution.

6. Environmental Pollution: Residual potassium chloride in soil can compromise crop quality, particularly by causing excessive potassium levels in agricultural products, posing health risks to humans. Furthermore, potassium chloride may seep into groundwater via rainwater, contaminating drinking water sources.

7. Waste of Agricultural Resources: Excessive potassium chloride use leads to resource waste. Despite its efficiency, the utilization rate of this fertilizer is low. Overapplication results in economic burdens for farmers and significant resource wastage.

8. Climate Impact: Excessive potassium chloride use may exacerbate climate change. The decomposition of potassium chloride in soil requires substantial energy, linking its overuse to increased greenhouse gas emissions and global warming trends.

excessive potassium chloride fertilizer use poses risks to soil, environmental, water, and human health. To protect agricultural ecosystems and public well-being, its application must adhere to scientific principles and avoid overreliance.
