Work Package 2

Consolidation, analysis and synthesis of historical data from long-term cropping system experiments and new experiments regarding adaption to CC

WP2 will consolidate and analyze historical data (climate, soil, environmental and agronomic performance) from long-term cropping systems (CS) experiments (LTE) from European agroecological environments.

Experiments involve management options such as: rotational design, tillage, irrigation and fertilization (form and level).

Data from short-term experiments (STE), e.g. on crop diversification, will also be made available for calibration and improvement of soil-crop models (WP4). Data will be used to test new hypotheses on effects of CS design regarding adaption to CC.

At some sites, additional process-based measurements will be made within existing long-term experiments to test hypotheses regarding adaptive capacity. We will test hypotheses regarding adaptive capacity of the soil-plant system under manipulated, IPCC-predicted, CC stress.

Soils from LT experiments will be used in controlled experiments in an ecotron, where climate stressors such as CO2, temperature and O3 are manipulated together with water stress.

Data and results from new STEs and syntheses from WP2 will be made available for WP1, WP3 and WP4.

WP2 includes four tasks:

► WP2.1: Management of historical data from long and short-term experiments for efficient data sharing between partners

► WP2.2: Extraction, analysis and synthesis of relevant historical data from long-term experiments in a CC adaption perspective and for use in soil-crop models

► WP2.3: New measurement and analyses in existing LTEs and STEs

► WP2.4: Ecotron tests of adaptive capacity of soil-plant systems when exposed to CC stressors
