Actual evapotranspiration from partially tile-drained fields as influenced by soil properties, terrain and crop
Physical properties of soils have a significant influence on their water regime and should be considered when selecting suitable agricultural crops for particular sites, taking into account the crop productivity and its water requirements. Mean daily rates of actual evapotranspiration (ETa) were obt...

520 | |a Physical properties of soils have a significant influence on their water regime and should be considered when selecting suitable agricultural crops for particular sites, taking into account the crop productivity and its water requirements. Mean daily rates of actual evapotranspiration (ETa) were obtained by collation of measured or otherwise estimated 10-min values for the years 2004, 2006 and 2009 for a partially tile-drained agricultural experimental catchment in the Bohemo-Moravian Highland (Czech Republic). ETa was measured using the Bowen ratio (β) and energy balance (BREB) method at four weather stations located on different soil types (Stagnosols, Cambisols) and terrain relief positions (defined with respect to the groundwater recharge and discharge zones) over different crops (cereals, oil rape and permanent grassland). A systematic influence of soil properties on the evapotranspiration rate was more pronounced during the periods of limited transpiration (soil drought, crop maturity), when the average daily ETa was significantly lower and the corresponding β significantly higher over coarser-textured soils (shallow Haplic Cambisols), namely (year-ETa (mm/day)/β): 2004 - 1.75/1.66; 2006 - 2.44/0.93; 2009 - 2.60/0.81), than over finer-textured soils (Stagnic Cambisols and Haplic Stagnosols), namely: 2004 - 2.92/0.97; 2006 - 3.06/0.44; 2009 - 3.42/0.39). When the transpiration was not limited by soil water deficit, it acted as an equalizing factor smoothing down evapotranspiration from heterogeneous soil areas, whereby the effect of the soil physical properties was masked. With regard to soil water regime and evapotranspiration, the tile-drained Stagnic Cambisol lands behaved similarly as non-drained Haplic Cambisols. The effects of land use and of the terrain relief position could not be tracked independently, because the permanent grassland was situated in the wetter and texturally heavier parts of the catchment and the positions of the recharge/discharge zone coincided with the positions of texturally lighter/heavier soils, respectively. | ||

Mean daily rates of actual evapotranspiration (ETa) were obtained by collation of measured or otherwise estimated 10-min values for the years 2004, 2006 and 2009 for a partially tile-drained agricultural experimental catchment in the Bohemo-Moravian Highland (Czech Republic). ETa was measured using the Bowen ratio (β) and energy balance (BREB) method at four weather stations located on different soil types (Stagnosols, Cambisols) and terrain relief positions (defined with respect to the groundwater recharge and discharge zones) over different crops (cereals, oil rape and permanent grassland). A systematic influence of soil properties on the evapotranspiration rate was more pronounced during the periods of limited transpiration (soil drought, crop maturity), when the average daily ETa was significantly lower and the corresponding β significantly higher over coarser-textured soils (shallow Haplic Cambisols), namely (year-ETa (mm/day)/β): 2004 - 1.75/1.66; 2006 - 2.44/0.93; 2009 - 2.60/0.81), than over finer-textured soils (Stagnic Cambisols and Haplic Stagnosols), namely: 2004 - 2.92/0.97; 2006 - 3.06/0.44; 2009 - 3.42/0.39). When the transpiration was not limited by soil water deficit, it acted as an equalizing factor smoothing down evapotranspiration from heterogeneous soil areas, whereby the effect of the soil physical properties was masked. With regard to soil water regime and evapotranspiration, the tile-drained Stagnic Cambisol lands behaved similarly as non-drained Haplic Cambisols. The effects of land use and of the terrain relief position could not be tracked independently, because the permanent grassland was situated in the wetter and texturally heavier parts of the catchment and the positions of the recharge/discharge zone coincided with the positions of texturally lighter/heavier soils, respectively. actual evapotranspiration bowen ratio cambisol cereals discharge zone energy balance grassland oil rape recharge zone soil physical properties stagnosol tile drainage transient zone Agriculture S Antonín ZAJÍČEK verfasserin aut Eva NOVÁKOVÁ verfasserin aut In Soil and Water Research Czech Academy of Agricultural Sciences, 2016 6(2011), 3, Seite 131-146 (DE-627)585506779 (DE-600)2465020-1 18059384 nnns volume:6 year:2011 number:3 pages:131-146 https://doi.org/10.17221/20/2010-SWR kostenfrei https://doaj.org/article/781481c2f3124512b004ef373e776380 kostenfrei https://swr.agriculturejournals.cz/artkey/swr-201103-0003_actual-evapotranspiration-from-partially-tile-drained-fields-as-influenced-by-soil-properties-terrain-and-crop.php kostenfrei https://doaj.org/toc/1801-5395 Journal toc kostenfrei https://doaj.org/toc/1805-9384 Journal toc kostenfrei GBV_USEFLAG_A SYSFLAG_A GBV_DOAJ GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_95 GBV_ILN_105 GBV_ILN_110 GBV_ILN_151 GBV_ILN_161 GBV_ILN_170 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_602 GBV_ILN_2014 GBV_ILN_4012 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4249 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4338 GBV_ILN_4367 GBV_ILN_4700 AR 6 2011 3 131-146 |

Actual evapotranspiration from partially tile-drained fields as influenced by soil properties, terrain and crop |
abstract |
Physical properties of soils have a significant influence on their water regime and should be considered when selecting suitable agricultural crops for particular sites, taking into account the crop productivity and its water requirements. Mean daily rates of actual evapotranspiration (ETa) were obtained by collation of measured or otherwise estimated 10-min values for the years 2004, 2006 and 2009 for a partially tile-drained agricultural experimental catchment in the Bohemo-Moravian Highland (Czech Republic). ETa was measured using the Bowen ratio (β) and energy balance (BREB) method at four weather stations located on different soil types (Stagnosols, Cambisols) and terrain relief positions (defined with respect to the groundwater recharge and discharge zones) over different crops (cereals, oil rape and permanent grassland). A systematic influence of soil properties on the evapotranspiration rate was more pronounced during the periods of limited transpiration (soil drought, crop maturity), when the average daily ETa was significantly lower and the corresponding β significantly higher over coarser-textured soils (shallow Haplic Cambisols), namely (year-ETa (mm/day)/β): 2004 - 1.75/1.66; 2006 - 2.44/0.93; 2009 - 2.60/0.81), than over finer-textured soils (Stagnic Cambisols and Haplic Stagnosols), namely: 2004 - 2.92/0.97; 2006 - 3.06/0.44; 2009 - 3.42/0.39). When the transpiration was not limited by soil water deficit, it acted as an equalizing factor smoothing down evapotranspiration from heterogeneous soil areas, whereby the effect of the soil physical properties was masked. With regard to soil water regime and evapotranspiration, the tile-drained Stagnic Cambisol lands behaved similarly as non-drained Haplic Cambisols. The effects of land use and of the terrain relief position could not be tracked independently, because the permanent grassland was situated in the wetter and texturally heavier parts of the catchment and the positions of the recharge/discharge zone coincided with the positions of texturally lighter/heavier soils, respectively. |
