Course abstract

The course sets out the amelioration tasks, methods and techniques for regulating soil moisture regime and the need for intensive agricultural production. Provide in-depth knowledge of the principles, materials, structures, structures, their parameters and calculation methodologies for the installation of drainage systems. Review the composition of works for the preparation of areas for agricultural use.

Learning outcomes and their assessment

After the course, the student will have:
• knowledge and understanding of the role of the amelioration package and the assessment of the necessity of the agricultural production process under specific environmental conditions, in accordance with the requirements of the production direction and the provision of technological processes. - examination
• skills to justify and address technical issues by choosing an appropriate method, techniques and package of measures to regulate soil moisture regime and to prepare areas in line with agricultural use objectives. - practical work
• competence to choose optimal solutions for soil drainage in relation to grounds for wetting, to perform theoretical calculations of the necessary justification for the measures adopted and to draw up graphical material; to assess in nature the technical state of the installation systems and structures, defects and the need for repairs. - course project

Criteria for Evaluating Learning Outcomes

Final test type written examination. Answers to questions covering the 20-course substance should be submitted, each question being evaluated in a five-point system. An exam with a nearly mediocre score (4 balls) settled if scored 40-45 points: 5 balls – 46-55 points, 6 balls – 56-65 points, etc., while 96 points and more correspond to a 10-ball rating.
