Abstract
In order to reduce the impact of agricultural activity on global warming and promote sustainable land management, it is necessary to implement management practices that reduce GHG emissions from agriculture. Conventional soil tillage produces favorable conditions for the growth of seeds and plants, but it is an energy and labor-intensive method that alters the soil to an unfavorable condition, while reduced soil tillage decrease the use of energy resources, GHG emissions from the soils, and improves the soil quality. Reduced soil tillage and crop rotation have been proposed as a solution to decrease GHG emissions from soil, and to improve soil quality. Therefore, the aim of this study is to research the effect of two soil tillage treatments and crop rotation on the GHG emissions from clay soil in Latvia. In the vegetation periods from 2018 to 2022, we measured soil flux of N2O, CH4 and CO2 using a mobile spectrophotometer Picarro G2508 on a broad multifaceted field experiment with conventional and reduced tillage treatments. The results show that N2O emission from clay soil significantly differs between soil tillage treatments (p less than 0.05).
