Methods for determining expenses of horizontal drainage under production conditions

Abstract

Currently horizontal drainage is a key ecological reclamation measure aimed at regulating water and salt regimes of soils, especially under conditions of irrigated agro-landscapes. Taking this measure becomes especially important under conditions of global and regional climate change. The operating conditions for horizontal drainage have changed resulting in changes in its efficiency. It is especially important for durable drainage, when its efficiency decreases it could even stop functioning. It requires a considerable number of research activities, but very few Ukrainian farmers can carry out monitoring research on the performance of horizontal drainage, constructed on their plots. It prevents from finding out negative aspects in horizontal drainage in time and taking appropriate measures. These difficulties can be avoided in case of using the developed and approbated methodology of recovering a number of horizontal drainage expenses through expenses of the research plots, determining the performance of horizontal drainage by these results and developing appropriate ecological reclamation measures to increase productivity of irrigated drained agro-landscapes.
