  1. Bio-physical Impacts of biomass crop management in AgricultureChristine Heumesser and Erwin SchmidUniversity of Natural Resources and Life Sciences (BOKU)

  2. Objective WP5: Sustainability Standards Task 5.1: geo-spatial bio-physical impact analysis • D5.1. Maps of production indicators for selected non-food crops for EU27 • D5.2. Maps of environmental indicators for selected non-food crops for EU27

  3. Data for bio-physical modeling in EU

  4. HRU delineation • Slope Class: • 0-3% • 3-6% • 6-10% • 10-15% • … • Altitude: • < 300 m • 300-600 m • 600-1100 m • >1100 m • Soil Texture: • Coarse • Medium • Medium-fine • Fine • Very fine • Soil Depth: • shallow • medium • deep • Soil Stoniness: • Low content • Medium content • High content

  5. Weather,Crop Rotation, and Crop Management PTF (Hyprese, pH, BD ...) CORINE-PELCOM NUTS2-level Data Processing daily time steps EPIC Simulations bio-physical Impacts EPIC INPUT DATABASE for soil and topographic parameters

  6. Food crop production systems in EU Major food/non-food crops (New Cronos) => crop rotation systems by NUTS2 (presented in Athens) Other non-food crop production options in EU Miscanthus(presented in Athens) Poplar coppice (presented in Athens) Reed Canary Grass (new) Management Options Optimizing fertilization (rates and timing) by EPIC & max. 170 kg/ha (Nitrates Directive), currently for food crops only (new) Environmental Indicators biomass yields, soil organic carbon (SOC), direct and indirect N2O-N emissions, nitrate leaching Progress of Work: Bio-physical Impact Analysis

  7. List of food/non food crops in the crop rotations • WWHT = winter wheat FPEA = field peas • DWHT = durum wheat SGBT = sugar beets • WRYE = winter rye RAPE = rape seeds • SBAR = spring barley SUNF = sunflower seeds • CORN = corn grain SOYB = soybeans • OATS = oats FLAX = flax • RICE = rice COTP = cotton • CSIL = corn silage FALW = set aside • POTA = potatoes GRCL = grass forages

  8. Crop yields reed canary grass N fertilizer Ø 5.1 t/hastd 1.1 t/ha Ø 88 kg/ha

  9. reed canary grass Nitrogen leaching(below sub-soil) Organic Carbon (in topsoil) Ø 65.1 t/ha Ø 0.7 kg/ha

  10. reed canary grass ‘indirect’ N2O-N emissions ‘direct’ N2O-N emissions Ø 2.3 kg/ha220 Gg Ø 0.87 kg/ha84 Gg

  11. N2O-N emission /N fertilizer miscanthus food crops Ø 6.2 % Ø 4.4 %

  12. N2O-N emission /N fertilizer reed canary grass poplar coppice Ø 11.9 % Ø 3.7 %

  13. Best Management Options • Automatic N fertilization with respect to N stress level. • Assumptions: • 90% of the crop growth period are N stress free • max. N 170 kg/ha

  14. N fertilizer Food crops for which fixed N-fertilizer amounts are assumed by crop and nuts2 region Crop Yields 4.0 t/ha 111 kg/ha

  15. Nitrogen leaching (below sub-soil) Food crops For which fixed N-fertilizer amounts are assumed Organic Carbon(in topsoil) 3.3 kg/ha 60 t/ha

  16. ‘indirect’ N2O-N emissions in kg/ha ‘direct’ N2O-N emissions in kg/ha Food crops for which fixed N-fertilizer amounts are assumed 0.97 kg/ha 5.5 kg/ha

  17. Change N fertilizer in % Food crops Change in Crop Yields in % +9.6 % +7.5 %

  18. Change in N leaching in % Food crops Change in organic carbon in % -8.8 % +0.5 %

  19. Change in ‘indirect’ N2O-N emissions in % Food crops Change in ‘direct’ N2O-N emissions in % +0.4 % -7.3 %

  20. Work in progress ccTAME data infrastructe very soon available – EU27 coverage and climate change impact simulations possible Design of best management practices for perennial biomass productions systems. Automatic N fertilization Automatic irrigation (similar to automatic N fertilization assuming water stress threshold. Plan for the next months
