Abstract
In the steppezoneon common chernozemsin the KarabalykAgriculturalExperimentalStationLLP in the Karabalykdistrict of Kostanayregion, dependingonmineralnutritionsystems, crop rotations,cropsandsoiltreatmenttechnologies, the dynamics of carbondioxideemissions from soils of agrolandscapesduring the development of landintensification was studied. The research was carried out bymeasuringcarbondioxide emissions using the Shtatnovtitrimetricmethod.Thepaperalsopresentsdataon the assessment of soilfertilityanditseffectoncarbondioxideemissions from various soil treatmenttechnologies.Basedonobservations of carbondioxidefluxesfromthesoilduring the growingseason, the mainpatterns of the dynamics of CO2emissionvariabilitydependingonseasonalityandabioticfactors(temperature,light,humidity,etc.)undervariousagricultural technologies,soiltreatment, crop rotationsystemsandfertilizers have been established for the first time. The resultsshowedthatinareaswithzerotillage(NoTill), there is a tendencytoincrease the biologicalactivity of the soil,which is confirmed by highercarbondioxideemissions.Atthesametime,traditionaltillageusingfertilizerscontributes to an increase in the concentration of nitratenitrogenandmobilephosphorus,whichcontributes to an increase in agronomicproductivity.
