Course Name : Management of problem soils and waters
Course Objectives
- To educate students about basic concepts of problem soils and brackish water, and
their management. - Attention will be on management of problem soils and safe use of brackish water in relation to crop production.
Course outcome (CO and PO maping)
- After learning the topic a student will be able to know about-
| COs | Course outcomes | Mapping COs with POs |
| CO1 | The students have knowledge with different types of problematic soils. | PSO1 |
| CO2 | Management process of problematic soils and reclamation techniques. | PSO2 |
PSO-Program specific outcomes
PSO1 : Impart knowledge and understanding of fundamental concepts and techniques of maintaining and enhancing soil fertility, crop production, crop management, crop improvement, biodiversity and sustainability of agriculture worldwide.
PSO2 : Develop the ability to know farming practices and their scope to improve in the rural areas and the environments.
PSO3 : Apply knowledge of basic science through Agricultural microbiology, Plant biochemistry and Biotechnology.
PSO4 : Apply knowledge of Agri-business management and finance to develop profitable agricultural system.
Course Syllabus
Theory
UNIT I
Area and distribution of problem soils – acidic, saline, sodic and physically degraded soils;
origin and basic concept of problematic soils, and factors responsible.
UNIT II
Morphological features of saline, sodic and saline-sodic soils; characterization of salt-affected
soils - soluble salts, ESP, pH; physical, chemical and microbiological properties.
UNIT III
Management of salt-affected soils; salt tolerance of crops - mechanism and ratings; monitoring
of soil salinity in the field; management principles for sandy, clayey, red lateritic and dry land
soils.
UNIT IV
Acid soils - nature of soil acidity, sources of soil acidity; effect on plant growth, lime requirement
of acid soils; management of acid soils; biological sickness of soils and its management.
UNIT V
Quality of irrigation water; management of brackish water for irrigation; salt balance under
irrigation; characterization of brackish waters, area and extent; relationship in water use and
quality.
UNIT VI
Agronomic practices in relation to problematic soils; cropping pattern for utilizing poor quality
ground waters.
Practical
Characterization of acid, acid sulfate, salt-affected and calcareous soils,
Determination of cations (Na+, K+, Ca++ and Mg++) in ground water and soil samples
Determination of anions (Cl-, SO4—, CO3— and HCO3-) in ground waters and soil
samples
Lime and gypsum requirements of acid and sodic soils
