Course Objectives
- To understand the chemical composition of soil and its role in plant nutrition and agricultural productivity
- To apply principles of water chemistry to analyze irrigation water quality and its effect on agro systems
- To study the chemistry of fertilizers, pesticides, and agrochemicals and their environmental impact
- To analyze the chemistry of food processing, preservation, and agro-product quality assessment
- To introduce green chemistry, biofertilizers, and sustainable agricultural chemistry for environmental conservation
Course Content
| Unit | Description | Weightage |
|---|---|---|
| 1. | Soil Chemistry: Introduction to soil and its composition; soil organic matter and humus; soil pH and its effect on nutrient availability; essential plant nutrients (macro and micronutrients); soil fertility, soil colloids, and nutrient retention; soil salinity and its impact on crop growth; basic soil testing, soil pollution, and soil management for sustainable agriculture. | 20% |
| 2. | Water Chemistry for Agro Systems: Physical and chemical properties of water, hardness (temporary and permanent), alkalinity, dissolved oxygen, BOD, COD, nitrogen cycle in water, phosphorus chemistry, irrigation water quality parameters (SAR, RSC, EC), water treatment for irrigation (coagulation, filtration, chlorination), groundwater chemistry | 20% |
| 3. | Agrochemistry: Fertilizers and Pesticides: Classification and chemistry of nitrogenous fertilizers (urea, ammonium nitrate, ammonia), phosphatic fertilizers (superphosphate, DAP), potassic fertilizers, micronutrient fertilizers, slow-release and controlled-release fertilizers, Introduction and classification of pesticides (organochlorines, organophosphates, pyrethroids, herbicides, fungicides), pesticide degradation and persistence, environmental effects of excessive agrochemical use. | 20% |
| 4. | Food Chemistry and Agro-product Quality: Chemical composition of food (carbohydrates, proteins, fats, vitamins, minerals), food adulteration and detection methods, Maillard reaction and browning, food preservation chemistry (pickling, canning, dehydration, irradiation), antioxidants and preservatives, quality parameters of oils, grains, and dairy products,and basics of food packaging materials. | 20% |
| 5. | Green and Sustainable Agricultural Chemistry: Green chemistry principles in agriculture, biofertilizers (Rhizobium, Azotobacter), biopesticides (neem, Bacillus thuringiensis), composting and vermicomposting chemistry, phytoremediation, biodegradable mulch films, agro-waste valorization, chemistry of renewable energy from agro-biomass | 20% |
Teaching-Learning Methodology
Topics are taught through interactive lectures using blackboard and ICT tools. Laboratory demonstrations on soil testing, water quality analysis, fertilizer identification, and food adulteration detection are included. Case studies on sustainable farming and agro-chemical management supplement classroom instruction.
