Analysis of Soil Water Response to Grass Transpiration
evapotranspiration root water uptake water stress function Richards’ equation preferential flow dual-permeability model lysimeter
<
2015/1/28
This paper focuses on numerical modelling of soil water movement in response to the root water uptake that is driven by transpiration. The flow of water in a lysimeter, installed at a grass covered hi...
Object-oriented Fuzzy Analysis of Remote Sensing Data for Bare Soil Brightness Mapping
remote sensing soil colour digital soil mapping fuzzy analysis fuzzy membership function
<
2015/1/28
Remote sensing data have an important advantage; the data provide spatially exhaustive sampling of the area of interest instead of having samples of tiny fractions. Vegetation cover is, however, one o...
Soil Heterotrophic Respiration Potential and Maximum Respiration Rate of Differently Managed Meadows
soil heterotrophic potential maximum respiration rate soil meadows mowing abandonment
<
2015/1/28
In this study were compared heterotrophic respiratory potential (VDS/VMAX) expressing an increase in C mineralisation rate after drying and re-wetting the soil to 60% soil water content (v/w)(VDS) in ...

soil conditions tobacco production
<
2014/10/28
The area devoted to growing tobacco (Nicotiana tabacum L.) in the province of Granma, Cuba, accounted for nearly 2600 ha in the year 1997, which represented the 4% of the total tobacco plantation area...
Effects of different regimes of fertilization on soil organic matter under conventional tillage
soil organo-mineral complex soil humic acid soil fulvic acid
<
2014/10/28
To explore the effects of different fertilization regimes on soil organic matter (SOM) sequestration in a winter-soybean/corn rotation, a long-term field experiment was conducted in Anhui, China, from...
Soil nematode responses to fertilization with ammonium nitrate after six years of unfertilized apple orchard
ecological indices soil food web bioindicator nitrogen fertilizer Malus domestica
<
2014/10/24
A nematode community was used as a bioindicator of changes in agroecosystems caused by fertilization. The effect of applying nitrogen (N) fertilizer on a soil nematode community structure was studied ...
Using the DNDC model to compare soil organic carbon dynamics under different crop rotation and fertilizer strategies
