Unit I: 
Basics of Soil Science
·         Soil formation: weathering and pedogenesis

·         Soil and subsurface environment

·         Soil profile and its layers

·         Soil properties-physical (density, porosity, texture, soil structure),  chemical (inorganic and organic)

·         Soil types in India

Collection and preparation of soil samples for analysis: sampling procedure, preparation of sample for analysis-drying, seiving, grinding, mixing, storing

 

Unit II: 
Soil Biology and Biochemistry
  • Soil biota, types of organisms in soil
  • Microbial diversity in soil- Microorganisms in surface soils, in shallow subsurface                 environments, in deep subsurface environments
  • Interactions among soil microorganisms-neutral, positive and negative associations
  • Humus formation

 

Unit III: 
Soil Contamination and Degradation
  • ·         Soil contamination due to metals, chemical fertilizers,  pesticide and their             effects
  • ·         Soil pollution-caused by industrial effluents (paper, textile, tannery, metal,             pharma)
  • ·         Soil degradation-causes, types (chemical and physical), measures to                  check soil degradation, remediation of degraded soil
  •           Soil conservation

 

Unit IV: 
Soil Fertility
  • Soil fertility and soil productivity; nutrient sources:

o   Soil nitrogen – forms, symbiotic nitrogen fixation, factors affecting nitrogen fixation

o   Soil phosphorus - forms, mechanism of phosphorus fixation, factors affecting phosphorus availability in soils

o   Soil potassium - forms, mechanism of potassium fixation, factors affecting the potassium fixation in soils

o   Micronutrients – Source of micronutrients in soils; factors affecting their availability

  • Integrated nutrient management
