Under irrigation, these procedures are summarized, where an irrigation using stationary or mobile Spraying is done. The irrigation is mainly used in humid climate areas operated. The water pipes will have to the facilities in the field pumped. Depending on the type, there are: irrigation with fixed, mobile and teilortsfesten Full and complete plants. As it is, more precisely between individual irrigation, irrigation district, or roll Rollzugberegnung finished (self) irrigation differ. The irrigation provides few demands on the surface of the area. Accordingly, it is also uneven terrain and independent irrigation, so that may be burdensome Planierungsarbeiten as well as the construction of dams, ditches or omitted. About the facilities may also be multipurpose irrigation. Thus, irrigation facilities for irrigation and frost protection for the application of fertilizers and pesticides used. The (Multi-) irrigation can be largely automated. Smaller Wasserzuläufe per area and more accurate dosing lead to low seepage and controlled Anfeuchtungstiefe. This will Versalzungsgefahr by capillary suction and Überwässerung reduced. Because of the irrigation water is not sent directly to the ground, but on the stock verregnet, is determined by high evaporative Interzeptionsverluste and a relatively low efficiency of water use from 65 to 75%. In addition to uneven distribution of water and wind along the edges of the fields. In addition to the high investment costs make spare parts store, a large energy demand and high operating, maintenance and renewal costs huge investments required. Likewise, a certain degree of training staff to use the repair and maintenance of irrigation facilities provided. The irrigation systems were initially for supplementary irrigation in humid climate area. Today in these regions from 50 to 90% of the irrigation area beregnet. Transition from the river for irrigation practices in the culture of wheat ArizonaWegen the many advantages of the procedure is spreading increasingly in semi-arid areas and is located there, according to the dam and irrigation furrows, in third place. Irrigation using fixed installations [Edit] For fixed installations, both the pumping station, as well as the supply and sprinklers installed fixed lines. Often, the supply pipes laid underground, the method is suitable only for perennial crops such as fruits, as a laying of pipes with a high cost. Irrigation systems using teilortsfester [Edit] When the plants are teilortsfesten intake pumping station and fixed lines installed, which Regner lines but can move flexibly in stock. This includes procedures such as circular or irrigation systems, sprinklers in which a car on ropes, sprinklers or a sled on the water hose through the stock is withdrawn
In order for the cross-field work necessary to achieve often have four-wheel drive tractors and at least two, often also four very large wheels with grobstolligen profile. The vehicle's steering is done with (electro) hydraulic support. Today's tractors are available for multiple uses in all its forms, as very small, especially in the mountains in the forestry or Serviced Alpine Pasture can be used for very small or large wine for farming in lowland areas. For optimal speed for the work to achieve, modern tractors often on a vielstufiges Last gearbox or a CVT. As additional equipment commonly used in tractors is a front loader, sometimes a rear loader appropriate. Larger tractors now mostly on a cabin with air conditioning and other vehicles to have technical features such as Einzelradbremse and differential locks. Special provide the Unimog, the device makers and the so-called Muli, which usually with a slightly longer wheelbase than other tractors are constructed. The device
