The Effect of Soil Coverings on Soil Respiration in Sandy Soil
Acta Agraria Debreceniensis, 2003 The purpose of our experiments is to study effect of different soil coverings (porous black polyethylene called agroszövet and black polyethylene) on CO2 production in sandy soil. The CO2 production was measured in our laboratory according to Witkamp (1966 cit. Szegi, 1979), after 5 days’ incubation period. Samples were taken off four times (March, May,

A model analysis on nitrate leaching under different soil and climate conditions and use of catch crops [PDF]
, 2005 The use of crops and catch crops with deep rooting can strongly improve the possibility of retaining nitrate-N that will otherwise be leached to the deeper soil layers and end up in the surrounding environment.
