Agricultural Meteorology involves the integration of climatological and meteorological data and techniques into agricultural problems, such as crop production, soil moisture, moisture stress, and migration of pests. A good background in basic maths and sciences is required. The chief concerns of modern agricultural meteorology are development of methods of forecasting meteorological phenomena that endanger agriculture and perfection of methods of long-range forecasting of the size and quality of yields, condition of winter crops in winter, and so on. Research in agricultural meteorology is conducted with special instruments, including remote-control instruments that do not affect the natural conditions of crop growing.
