Combating the Erosion Phenomenon. The Decanting Pondfromfânaţe Village, Bihor County, Romania−Case Study

Abstract Decanting ponds can have a major impact on the environment, as they often contain heavy metals.In the absence of their monitoring and security, but especially during the greening processs, the potential risk of technical accidents occurenceincreased significantly.In such events, both the environment and human settlements are affected; sometimes major pollution with cross-border impact may occur.The Fânaţe decanting pond is located in Fânaţe village, Cîmpani commune, Bihor county, Romania.The arrangement works within the decanting pond aim to establish and consolidate the banks and its base. This paper presents some solutions for combating the erosion phenomenon

IRRIGATION INFLUENCE ON WATER CONSUMPTION, YIELD AND WATER USE EFFICIENCY IN POTATO IN THECRI?URILOR PLAIN CONDITIONS

The paper is based on the research results obtained during 2001-2005 in Oradea in the long term trial placed on preluvosoil in 1976. During the vegetation period of the potato, the following quantity of the rainfall were registered: 426.2 mm in 2001, 210.4 mm in 2002, 165.4 mm in 2003, 359.6 mm in 2004 and 335.2 mm in 2005. To maintain the soil water reserve on 0-75 cm between easily available water content and field capacity, the irrigation rate used was of 40.0 mm in 2001, 271.0 mm in 2002, 287.0 mm in 2003, 157.5 mm in 2004 and 65.0 mm in 2005. Irriation determined the increase of the values of the water consumption with 7.4% (618.2 mm vs 575.7 mm) in 2001, with 48.9% (526.2 mm vs 353.4 mm) in 2002, with 79.2% (585.5 mm vs 326.8 mm) in 2003, with 26.0% (632.0 mm vs 500.8 mm) in 2004 and 17% (580.6 mm vs 496.5 mm) in 2005.
