Agriculture and Nature Panel Draft review (Segovia 2005) Only few but critical comments Leading co-author found, Klaas van der Hoek Agreement on the chapter’s content in Vienna 2006 (IIASA) Problems to find reliable data for EF Main sources are combine harvester and tractors with machinery during soil cultivation
Measuring Dust Emission of a Self Propelled Combine Harvester
EF10 for Soil Cultivation: Layer Model area [104 m2] balance volume V = 2 ·104 m3 c mg/m3 h = 2 m EF10= c · V · n (n = annual repetitions)
balancing area wind speed EF10 = c · A · w · t EF10 for Soil Cultivation: Plume Model
Kg PM10 per ha arable land IIASA IR 02-076 0.1 UK ASAE 02-4217 0.5 California Air Resources Board soil cultivation 7 Idem wheat combining 5.8 German research soil cultivation 1.1 Idem harvest operations 5.2 NL harvest operations 0.2 Some emission data, but how much PM10 will actuallyleave the agricultural field?
EPA formula for emissions from agricultural crop tilling E = c * k * s0.6 * p * a E = PM emissions in pounds/year C = 4.8 lbs/acre tilling K = 0.21 for PM10 and K = 0.042 for PM2.5 S = mass fraction < 0.75 um in soil layer 0-10 cm P = nummer of tillings/passes in a year A = acres of land tilled for each crop type 1 lbs/acre = 1 kg/hectare
