Study Notes
Tracer Methods of Water Measurement
- The main advantage of tracer methods is not specified in the provided text, but the method requires measuring velocity, depth, head, and cross-sectional area of the stream.
Irrigation Scheduling
- Irrigation scheduling is based on the frequency of water application according to the needs of the crop and nature of the soil.
- The goal of irrigation scheduling is to achieve maximum crop production per unit of water applied over an area in a specific time.
Concept of Irrigation Facility
- The concept is that agricultural production and productivity will automatically increase with the provision of irrigation facility.
- The popularity of the tracer method of water measurement in India is a notable fact.
