  We examined the change of the time of water balance of soil in long-term experiment, on chernozem soil, in different croprotation systems (mono-, bi- and triculture). We found the smallest difference between the water deficit of not irrigated and irrigated plots in triculture. We concluded that irrigation impressed favourably on water balance of soil in both of crop-rotation systems. Water deficit has decreased significantly after irrigation
  in 25. May in mono- and triculture. Irrigation moderated only values of water deficit. Irrigation in 30. June not influenced water balance of soil in both of crop-rotation because of a big drought. Water deficit of soil lessed till harvestperiod because of rainy season at the end of August and in September.

  Optimal sowing time for perennial sorghum under irrigation is when soil temperature at the depth of sowing reaches up to 10–11 °С, harvesting for the green mass has to be done when panicle is situated on the stem in 10 sm from the flag leaf and hight of cut must be 11 sm.

  Virtualization is increasingly taking on a key role in various system architectures which follow new platform concepts like Software as a Service (SaaS). This trend addresses more instant and short-term environments and comes with new methods and strategies for the distribution of mainly complex application stacks not only in large IT infrastructures. The paper presents how a so called Virtual Appliance can be set up in order to operate in virtual server environments using hypervisor software like Oracle Virtual-Box. Using the example of two server-side components within the Integrated Land Management System (ILMS), it will be shown that the use of state-of-the-art methods, standardized tools and interfaces on servers enables different aspects of environmental system management, analysis and planning.
