Course abstract

Irrigation: history and development in the world, EU and Latvia. Water balance of the soil and irrigation requirement of the agriculural crops. Types of the irrigation systems. Surface irrigation (furrow irrigation, border irrigation, basin irrigation). Sprinkler irrigation, sprinkler equipment and practice. Drip (tricle) irrigation. Subsurface irrigation. Water sources, layout and design of pipelines. Irrigation water quality. Maintenance of irrigation systems.

Learning outcomes and their assessment

• The course develops knowledge and understanding on the development of irrigation and its role to provide suitable soil water balance for crops.
• The course enables students with an ability to evaluate soil moisture balance and use of water resources with the scope on course works, projects and graduation works in the field of their study topic.
• The course elaborates competence to use the basic principles of irrigation that govern the control of soil moisture problems, that students can then bring to elaborate their projects and research approaches on relevant issues of their main field of studies.

Requirements for awarding credit points

Successfully passed final test on the lecture topic

Description of the organization and tasks of students’ independent work

The student learns the theoretical part by participating in lectures and independently studying the recommended literature. The acquired theoretical knowledge is used to take the final exam at the end of the theoretical part. In the final exam, the student successfully passes the test by answering the questions discussed in the lectures

Criteria for Evaluating Learning Outcomes

The test for the theoretical part is organized in writing in the e-study environment and consists of 50 questions. To pass the test, at least 50% (25 questions) have to be answered correctly.
