The Kyzylorda oblast is located in the south of the republic in a zone of deserts with sharp and continental climate along the bottom current of the Syrdarya River, occupying a considerable part of the Turansk lowland. In the West its structure includes the Small Aral Sea, in the south - a northern part of the sandy Kyzyl Kum Desert - one of the largest deserts of the Old World, in the north - Priaralsky Kara Kum, Aryskuma and desert plateaus of the suburb of the Kazakh folded country or Melkosopochnik. In the extreme northeast on the right coast Syr-Darya the extremity of ridge of Karatau being an extreme spur of mountains Tian-Shanya comes into area limits on small space.
The natural landscape of Kyzylorda oblast is composed by sandy and clay massifs overgrown with bushes and a saxaul, in a flood plain of the Syrdarya River wood tugayny thickets meet. Between the Kyzyl Kum Desert and a plateau of the Kazakh folded country extensive spaces of the ancient and modern river plains obliged by the formation of activity of Syrdarya were stretched. A left bank of Syrdarya - extensive sand Kyzyl Kum, in which territory the saksaul forestry largest in the republic.
Thanks to rather southern geographical arrangement of the territory of the oblast corresponding to the North Caucasus and an average zone of Italy, in considerable remoteness from water spaces (3-4,5 thousand km), the climate of the oblast differs sharp continentality and dryness. Absolute maxima of temperatures reach to 46 °, and at least to a minus 37 °, i.e. fluctuations reach 87 ° degrees that seldom meets on the globe.
Quantity of sunny days in a year is more than 300. The maximum air temperature makes 11 ° S.Period with air temperature higher 5 ° is the beginning of the vegetative period of wild-growing herbs, above 10 ° - the beginning of sowing of rice, and more than 15 ° - a cotton. Duration of the vegetative period fluctuates from 190 to 226 days in a year. The warm period proceeds till October inclusive. Snow drops out in November (steadily in December), and in March melts. The height of snow cover doesn't exceed 15 mm. Evaporation exceeds a precipitation in 10 and more times.
The number of days with strong winds on the most part of the territory of the oblast makes 2-22, around Zhusaly - 45-65. In a warm season dusty storms - on the average during the season are observed 2-20 days. Wind-shelter strips are necessary for protection against northeast winds along the rivers, on borders of fields of crop rotations and boards of the main channels.
The number of days with a precipitation makes 40-60, and in all territory a rain precipitation prevails over snow in 1,5-2 times. In exclusive years the sum of a precipitation can fall to 30 mm or increase to 220 mm. A precipitation has mainly storm character and their duration is, as a rule, insignificant in the summer. The greatest daily amount of precipitation in June makes 40-50 mm (1 time in 40 years) and 30-40 mm (1 time in 80 years) in July and August. The minimum of an atmospheric precipitation falls on summer months (10-25 mm), at most on spring - 30-60 mm. Generally the annual amount of precipitation insignificant also decreases from the southeast on the northwest - from 90 to 160 mm.
Summer precipitation entirely evaporates, autumn and spring is completely spent for a superficial drain and only winter a little souse the soil, creating conditions for development of early-spring vegetation.
Grain crops - wheat, barley, oats, millet - for ripening demand till 115 days and the sum of temperatures for this period about 1600 °, for olive (sunflower, mustard), commercial crops (a sugar beet, early ripening varieties of a cotton), and also some grades of the corn, which vegetative period of 120-140 days, the sum of temperatures - from 2000 ° to 3000 °.
Therefore the temperature mode of the oblast allows cultivation of all listed above crops, first of all rice, as leading grain culture.
