Cím:CO2 emission and Long-term prediction of Carbon stock change of the soil in different soil tillage systems / Szőllősi Nikolett, Zsembeli József, Kovács Györgyi, Juhász Csaba
Dátum:2009
ISSN:1224-6255
Megjegyzések:Agricultural soils, having been depleted of much of their native carbon stocks, have a significant CO2 sink capacity. Global estimates of this sink capacity are in the order of 20-30 Pg C over the next 50-100 years. Management practices to build up soil C must increase the input of organic matter to soil and/or decrease soil organic matter decomposition rates. The most appropriate management practices to increase soil C vary regionally, dependent on both environmental and socioeconomic factors (Paustian et al., 1997a). In complex soil tillage experiment in 1997 was set on at Karcag, as the element of the investigation of soil reduced and conventional tillage systems, in situ measurements have been carried out since 2002 in order to determine the CO2-emission of the soil. Calculations by the IPCC methodology were also done to quantify the effect of various soil tillage methods on the carbon stock change in the soil. Period of calculation was 20 years. In addition a comparison was made bases of the comparison of measured and calculated data by 2008. The results we gained call the attention to the complexity of the correlation between soil tillage and carbon stock change, and also to the utilisation possibilities and limits of the measured and calculated data.

Cím:Microbiological activity under stubbles in different soil cultivation systems / Zsembeli J., Kovács Gy., Tamás J.
Dátum:2007
ISSN:1224-6255
Megjegyzések:There is close correlation between the degree and intensity of CO2-emission from the soiland the structural state and organic matter content of the soil. Applying alternative soil cultivationmethods based on reduced disturbance of the soil more favourable conditions can be created in orderto increase the organic matter content of the soil and the availability of the nutrients for the crops. Inorder to quantify the increased CO2-emission from soil due to soil preserving cultivation systems, insitu CO2-emission of soil was measured by means of an ANAGAS 98 infrared gas analyser. In thispaper the results gained from the measurement on stubbles are published, as we consider stubbles themost suitable state when the effects of different soil cultivation systems on the microbiological activityof the soil can be compared. Studying the effect of different soil utilisation/cultivation methods on theCO2 emission from soil is indisputably actual and needs more efforts as it can contribute to develop amore environmental friendly agricultural production.
