Аннотация:Data on soil response to changes in agricultural management from controlled experiments in representative climatic regions and on representative soils make it possible to minimise the time and cost of the evaluation of a particular practice. The development of sustainable land management technologies in agriculture implies a wide application of field experimental data and models designed to describe changes which occur very slowly, such as changes in soil organic C (SOC) levels. The combined impact of different management practices (inorganic fertilisers, manure and different rotations), climate and soil properties on SOC changes was analysed using a static model. The information for the model was integrated from 60 long-term experiments on arable soddy-podzolic soils in the Russian Federation, Belarus, Ukraine, Latvia and Lithuania. The model was applied for the elaboration of optimal crop rotations and fertilisation practices that lead to SOC sequestration. Quantitative estimates of management options for enhancing the SOC pool thus improving soil quality and biomass productivity were presented for different districts of the Moscow Region and regions of the European Russia under current climate. Different possibilities of applying the SOC model in combination with GIS databases were demonstrated. The proposed approach links assessments of crop yields, soil fertility and incomes in the management practices tested.
