Strategies and Tips for Preparation of ICAR AIEEA PG/JRF Exam in Physical (Soil) Science Group

(By R S Maitry, Ex-Scientist, ICAR-IARI, Soil Physics)

1. Know the Syllabus and Exam Structure

• Go through the official ICAR AIEEA PG syllabus for Soil Science with focus on: Soil Physics, Soil Chemistry, Soil Fertility, Soil Mineralogy, Soil Biology & Biochemistry, Problem Soils, and Soil and Water Conservation.
  
  

• The exam includes 120 multiple-choice questions to be solved in 2 hours. Understanding the pattern and weightage of each topic is crucial for planning.
  
  

2. Focus on Conceptual Clarity

• Strengthen your fundamentals from standard textbooks like:
  
  

  • Fundamentals of Soil Science by Indian Society of Soil Science (ISSS)
    
    

  • Introductory Soil Physics by D.K. Das
    
    

  • Soil Chemistry by Biswas & Mukherjee
    
    

  • Soil Fertility and Nutrient Management by Tandon
    
    

• Understand principles of soil properties, processes, and analytical methods.
  
  

3. Create a Smart Study Plan

• Divide your preparation time across units based on complexity and weightage. For example:
  
  

  • Week 1–2: Soil Physics & Chemistry
    
    

  • Week 3–4: Fertility, Microbiology & Problem Soils
    
    

  • Week 5: Soil & Water Conservation + Revision
    
    

• Daily target: 3–4 hours for new concepts, 1 hour for revision, and 30 minutes for MCQ practice.
  
  

4. Practice Previous Year Papers and MCQs

• Solve previous 5–10 years' ICAR papers to understand repeated questions and trending topics.
  
  

• Practise MCQs from trusted sources like NIPA books, AgriMoon, and Agriexam question banks.
  
  

• Keep a notebook of important solved questions and tricky concepts.
  
  

5. Revise Effectively

• Make short notes, charts, and formula sheets for topics like:
  
  

  • Soil Texture Triangle
    
    

  • Darcy’s Law
    
    

  • pH-buffering systems
    
    

  • Nutrient Mobility and Soil Amendments
    
    

• Revise each unit at least 2–3 times before the exam with focus on one-liners and definitions.
  
  

6. Regular Mock Tests and Self-Evaluation

• Attempt full-length mock tests weekly to simulate the actual exam scenario.
  
  

• Analyze your errors and work specifically on weak topics.
  
  

• Use a timer while solving mock tests to improve speed and accuracy.
  
  

7. Use Expert Guidance and Digital Resources

• Watch expert sessions, toppers’ strategies, and revision lectures on platforms like YouTube and online coaching portals.
  
  

• Follow updates on agricultural current affairs, recent soil innovations, and government schemes related to soil health.
  
  

8. Stay Consistent and Balanced

• Avoid skipping topics, even if they seem minor. Questions often come from less expected areas.
  
  

• Maintain mental and physical health with a proper routine, regular breaks, and positivity.
