SES-504 SOIL FERTILITY AND FERTILIZER USE

3(2-1)

 

Objective and Learning Outcome

 

Plant nutrients availability, replenishment and retention as well as use and behavior of fertilizer in soil are discussed. The students should be able to diagnose nutrient deficiency and toxicity symptoms and requirement of fertilizers for optimum plant growth.

 

Course Contents

 

1.            Crop growth, factors affecting and growth expressions

2.            Essential plant nutrients: functions, deficiency and toxicity

3.            Movement of nutrients to roots, acquisition and uptake

4.            Nitrogen gains and losses in soil

 

5.            Nitrogen fertilizers and their fate in soil

6.            Phosphorus forms and P-fertilizers behavior in soil

7.            Potassium forms, amount and exchange equilibrium in soil

8.            Calcium, magnesium and sulfur forms and amount in soil

9.            Crop responses; factor affecting and residual effects

 

10.        Integrated plant nutrient management

11.        Nutrients behavior in submerged soil

12.        Nutrient role in human and plant health

13.        Micro Nutrients role and deficiency symptoms

 

Practical

 

1.            Fertilizers identification and composition

 

2.            Fertilizer requirement calculation

 

3.            Fertilizer analyses (urea, CAN, DAP and SOP)

4.            Determination of available P and K in soil

 

5.            Plant analysis for N, P and K sufficiency and uptake
