Effect of transit gas pipeline temperature on the production potential of agricultural soils/ Vplyv teploty tranzitneho plynovodu na produkcny potencial pol'nohospodarskych pod

The aim of our study was to investigate the temperature effects of a transit gas pipeline on soil and harvested crop over the years 2004-2006. The study area was located in the village Vel'ky Cetin (Nitra District, South-Western Slovakia) soil type is Mollic Fluvisols calcaric. The temperature of the transported gas increased the soil temperature in the range of 1.1 to 1.75°C (average) above the gas lines. It also reduced soil moisture by 0.07-2.67 weight per cent (average). The wheat yields above the gas pipelines decreased by 3.63% in 2004 and by 9.53% in 2006. Yield of barley also decreased by 13.88% in 2005.
