Current trends in development of microirrigation

key words: microirrigation, development, current trends


Current trends in development of microirrigation were presented in this paper. Irrigation systems are the complicated pattern which needs the active operation including service and the use of facilities. Irrigation technologies se-cure the solution of such the problems of the current world as: rapid increase of population, limitations of natural resources and the environmental degradation. During the last three decades, the irrigation systems played an important role in the increase of the food production. The irrigated area (15% of the arable area in the world) gives the yield of the value about 36% of the total crop production value. It is connected with many social, environmental and technological prob-lems. The use of irrigation is successful when the utilization of water, soil and atmosphere is integrated, the irrigation technology is improved and the influence of irrigation on the environment is controlled as well as the environmental moni-toring is conducted. Crop production needs the increased use of technologies which are precisely adapted to needs of crops. In this case the creation of sus-tainable technological- economical- and ecological configurations can be possi-ble. The future investigations should include the following problems: technology of irrigation (doses, frequency, time of the single water application, emitter dis-charge), effective control of irrigation, development of root system, uptake of wa-ter and nutrients by plant roots, dynamics of wetting front, the number of emitters per plant, monitoring of dynamics of the abundance on irrigated soils, minimiza-tion of soil and groundwater pollution.
