Tkachuk A. Calculation of soil moisture reserves technology according to the agrometeorological date and moisture supply agricultural crops of forest-steppe zone of Pravobereznaja Ukraine

Aubject: the process of spatial and time changeabilitg of moisture deposit; Aim: groundwork of methods of calculation of daily moisture deposit in different soil layers and determination natural moisture provision of sowing of leading agricultural crops in different atmosphere moisten years. Yroundwork of resource sowing of irrigation of main cgops on research territory; Metohods: analysis, mathematical and statistical. Novelry - for the tirst time discovered for the research territory empiric dependence of moisture deposit from complex range indicator of previons weather conditions under leading crops sowing; developed methodins of calculation of daily moisture deposit in 0-50 cm and 0-100 cm of soil layer; for the first time for every day of critical period the mark relating to the providing of leading crops with moisture deposit is given according to different natural moistened years. Results: for theory - methods of calculation of moisture deposit can be developed for anolher agroclimatical sones and agricultural crops; for practicl - implementation info production of proposed methods of calculation moisture deposit will promote the effective mechanesm of regulation of to create water distribution, economical using of irrigation water, for creation of automated regime management in irri gation. Field - agriculture.
