Abstract
Similar amounts of organic carbon was also found in Cereal and For green manure crop rotations.Soil organic carbon in Continiuos bare fallow obtained two times less comparing with oher investigated crop rotations. Bare fallow without farmyard manure application mostly decreased soil productivity.Crop rotation design in modern agriculture persist as one of major instruments for soil organic carbon managements and sustainable intensification.
Identification and implementation of land use and soil management practices which create a positive agricultural soil/ecosystem carbon budged and restore soil quality is specific challenge worldwide. Moreover, soil carbon sequestration is almost only negative emission technologies which are readily available at a low cost and crop rotation is one of those. The objective of this investigations was to compare the effect of different crop rotations and Rye monocultures as well as fallow on soil organic carbon. Long - term field experiment was established in 1966 at the Experimental Station of Aleksandras Stulginskis University. 9 different crop rotations were arranged in time and space. In addition, Corn and Rye monocultures as well as Continuous bare fallow were included as control treatment. Soil - Calc(ar)i- Endohypogleyic Luvisol. Investigation were carried out in 2015. Soil samples were taken in different crop rotations in 0-20 cm depth and soil organic carbon was determined spectrophotometric method. Winter wheat is grown in Cereal, Field with raw crops and Norfolk crop rotations. The highest organic carbon content was found in winter wheat crop in Norfolk crop rotation. Cereal crop rotation has an organic carbon content of less than 1.1 to 1.2 times compared to other crop rotations. Winter rye crops are grown in Intensive , Field with raw crops, For green manure and Three course crop rotations, as well as Winter rye monoculture. In winter rye crops, the highest amount of organic carbon was observed in Intensive and Field with raw crops crop rotations. The lowest in For green manure and Three course crop rotations. Barley crops are grown in Intensive, Cereal, Field with raw crops, For green manure, Norfolk and Fodder crop rotations. The highest organic carbon content was found in Norfolk and Fodder crop rotations compared to other crop rotations. The least organic carbon content was found in Intensive crop rotation.
