Known podlavnoe water wheel (Noria). It in ancient times used for irrigation ancient Egyptians and Persians. In the simplest bucket on the rim installed straight blades; lower blades are immersed in the water stream. For pressing on the scapula, and the wheel rotates. To increase the energy extraction from a water source blade wheels are made in the form of buckets (http: //adetiplus/EN, http: //dic/academic.ru). The height of rise of the water bucket Elevator reaches 60 meters
The disadvantage of this device is the lack of clean water from the waste before feeding it into the irrigation system.
Known rotary filters series HDF 12/16/20 for water purification (http: //www.aqvafeed.ru).
The disadvantage of this device is its complexity, the use of electric drive and the need for periodic backwashing of the filter.
Known technology for improving soil fertility by instillation of burnt trees in the ground, used by the Indians living in the Amazon basin before the discovery of America by Columbus. Currently, the charcoal produced in the pyrolysis of wood, in combination with mineral fertilizers is also used to improve the fertility of the soil. For growing trees charcoal buried in the trench, along which zagibautsa seedlings. This also solves the problem of reducing the acidity of the soil carbon stocks in the soil and reduce revenues greenhouse gas (CO2), nitrous oxide and methane from soil into the atmosphere (http : //en.wkipedia.org/wki/Biochar -).
The disadvantage of this technology is the lack of adapting it for use in irrigated agriculture, the need for the use of mineral fertilizers, which can have a negative impact on the environment.
Known systems of soil mulching crop residues in crop production, reducing evaporation from the soil surface and condensation of water vapor in it from the surface air. System of planting fruit trees with distance between them of more than 6 m allow themselves to trees to generate an optimal crown that does not require trimming (Kurdyumov NI encyclopedia of smart summer resident. - Rostov n/D: Vladis; M REEPOL classic, 2009. - 512 S.).
