Review of Rare Earth Elements as Fertilizers and Feed Additives

“…In particular, rare earth elements such as lanthanum are extensively used in micro-fertilizers and micro-feeding in agriculture, animal husbandry, and aquaculture.

Rare earth elements (REEs) are critical metal elements with unique physical and chemical properties. Their application in agriculture has garnered significant attention. whether REEs can replace calcium fertilizer remains a contentious topic. This article analyzes the differences, advantages, and potential challenges between REEs and calcium fertilizer to provide insights for agricultural production.

1. Basic Characteristics of REEs and Calcium Fertilizer

• Rare Earth Elements (REEs): REEs refer to a group of elements including lanthanides, scandium, and yttrium. Their distinctive electron configurations and energy levels confer unique properties. In agriculture, REEs are used as trace element fertilizers to regulate soil pH, improve soil structure, and enhance microbial activity.

• Calcium Fertilizer: Calcium fertilizers, such as lime and calcium sulfate, primarily supply calcium to soils. They play a critical role in supporting plant growth, disease resistance, and soil health by replenishing calcium deficiencies.

2. Soil Amendment Roles of REEs and Calcium Fertilizer

• REEs:

  • pH Regulation: REEs form stable complexes with soil cations, reducing pH and enhancing nutrient availability.
  • Soil Structure Improvement: They increase soil aeration and water-holding capacity, promoting root development.

• Calcium Fertilizer:

  • Calcium Supplementation: Directly addresses calcium deficiencies, strengthening cell walls and improving stress tolerance in plants.
  • Soil Health: Enhances soil aggregate stability and reduces compaction risks.

3. Agricultural Advantages of REEs and Calcium Fertilizer

• Advantages of REEs:

  • Soil Acidity Management: Effectively lowers alkaline soil pH.
  • Crop Quality Improvement: Boosts yield, disease resistance, and nutritional content.
  • Sustainable Soil Use: Reduces reliance on synthetic fertilizers over time.

• Advantages of Calcium Fertilizer:

  • Essential Nutrient Supply: Fulfills calcium requirements for plant physiological processes.
  • Disease Mitigation: Strengthens plant defenses against pathogens.
  • Growth Promotion: Accelerates developmental stages and increases productivity.

4. Limitations of REEs and Calcium Fertilizer in Agriculture

• Limitations of REEs:

  • High Costs: Extraction and processing of REEs are economically burdensome.
  • Environmental Risks: Potential for soil and water contamination if improperly managed.

• Limitations of Calcium Fertilizer:

  • Excessive Use Risks: Over-application may lead to soil compaction and nutrient imbalance.
  • Limited Targeting: Less effective in addressing specific micronutrient deficiencies.

5. Integrated Application of REEs and Calcium Fertilizer

Combining REEs with calcium fertilizer offers a synergistic approach:

• Cost Efficiency: Reduces reliance on singular high-cost or high-risk inputs.
• Holistic Nutrient Management: Addresses both macro- (calcium) and micro- (REEs) nutrient needs.
• Environmental Safeguards: Minimizes ecological impacts through balanced application.

6. Recommendations

• Research Priorities: Investigate optimal application rates, interactions, and long-term effects of REEs and calcium fertilizer.
• Precision Fertilization: Tailor blends to crop types, growth stages, and soil conditions.
• Sustainability Focus: Prioritize eco-friendly practices, such as organic fertilizers and microbial agents, to complement REE and calcium use.

While REEs and calcium fertilizer each offer distinct benefits, their combined use holds greater potential for sustainable agriculture. By leveraging scientific research and targeted application, farmers can optimize productivity, reduce environmental risks, and promote green agricultural development.
