1. Environmental pollution: Inorganic fertilizers can lead to water and soil pollution due to the leaching of excess nutrients into water bodies, causing eutrophication. This can harm aquatic ecosystems and disrupt the balance of nutrients in the environment.
2. Soil degradation: Continuous use of inorganic fertilizers can lead to soil degradation, as they do not improve soil structure or fertility in the long term. This can result in decreased soil health and productivity over time.
3. Reduced biodiversity: Inorganic fertilizers can negatively impact soil microorganisms and beneficial insects, leading to a decrease in biodiversity in the agricultural ecosystem. This can disrupt natural processes and reduce the resilience of the ecosystem.
4. Health risks: Inorganic fertilizers may contain harmful chemicals and heavy metals that can pose health risks to humans and animals if they are ingested through contaminated food or water sources. Prolonged exposure to these chemicals can lead to various health problems.
5. Cost: Inorganic fertilizers can be expensive, especially for small-scale farmers, leading to increased production costs and reduced profitability. This can make it difficult for farmers to afford these inputs and may limit their ability to invest in sustainable farming practices.
6. Nutrient imbalance: Inorganic fertilizers typically provide a limited range of nutrients, which can lead to nutrient imbalances in the soil and crops. This can affect crop growth and yield, as well as the nutritional quality of the produce.
7. Dependency: Continuous use of inorganic fertilizers can create a dependency on these inputs, as they may deplete the soil of essential nutrients and disrupt natural nutrient cycling processes. This can make it difficult for farmers to transition to more sustainable farming practices in the future.

Environmental Concerns:
- Nutrient leaching: Inorganic fertilizers can be easily lost through leaching, polluting water bodies and contributing to eutrophication.
- Soil acidification: Ammonium-based fertilizers can acidify soils over time, reducing crop productivity and soil biodiversity.
- Greenhouse gas emissions: Nitrogen fertilizers contribute to nitrous oxide (N2O) emissions, a potent greenhouse gas.
Soil Health Impacts:
- Soil depletion: Inorganic fertilizers provide only specific nutrients, depleting soil of others and disrupting soil balance.
- Loss of soil organic matter: Excessive use of inorganic fertilizers can reduce soil organic matter, which is essential for soil health and water retention.
- Soil compaction: Heavy fertilizer applications can compact soil, reducing water infiltration and root penetration.
Crop Quality:
- Reduced nutrient uptake efficiency: Inorganic fertilizers can provide nutrients in excessive amounts, making it difficult for plants to absorb them effectively.
- Reduced crop diversity: Over-reliance on inorganic fertilizers can discourage the cultivation of nutrient-fixing legumes and other crops that promote soil fertility.
- Pesticide dependence: Inorganic fertilizers can increase pest problems by reducing plant resilience and suppressing natural enemies.
Economic Considerations:
- High cost: Inorganic fertilizers are often expensive, especially in developing countries where access to inputs is limited.
- Dependence on external sources: Crop production becomes dependent on external inputs, making farmers vulnerable to market fluctuations and supply chain disruptions.
- Reduced long-term profitability: Excessive use of inorganic fertilizers can lead to soil degradation and reduced crop yields in the long run.
Additional Limitations:
- Soil type-specific requirements: Different soil types have varying nutrient needs, making it challenging to apply inorganic fertilizers universally.
- Climate variability: Inorganic fertilizers may not be effective in all seasons or under different rainfall patterns.
- Lack of nutrient synergy: Inorganic fertilizers do not provide the balanced nutrient blend found in organic sources, which can impact crop quality and yield.
- Nutrient leaching: Inorganic fertilizers can be easily lost through leaching, polluting water bodies and contributing to eutrophication.
- Soil acidification: Ammonium-based fertilizers can acidify soils over time, reducing crop productivity and soil biodiversity.
