Heterogeneity of soil properties at the field-scale and spatial patterns of soil-borne pests and weeds
(2012-04-16)
Soil heterogeneity at the field-scale not only affects crop growth and yield, but also spatial patterns of soil-borne pests and weeds. Therefore, site-specific management in due consideration of soil variability is required ...
Effects of 137Cs and 90Sr on structure and functional aspects of the microflora in agricultural used soils
(2013-03-01)
At long sight 137Cs and 90Sr are the main radionuclides responsible for the contamination of agricultural soils due to core melts in nuclear power plants such as Chernobyl or Fukushima. Once deposited ...
Soil organic carbon pools and their spatial patterns: rapid assessment using mid-infrared spectroscopy
(2011-02-09)
Soil organic carbon (SOC) plays an important role in global C cycling. Until today, the spatial patterns of individual SOC fractions are, however, largely undiscovered as traditional methods for their determination are too ...
Quantitative characterization of solute transport processes in an undisturbed unsaturated soil by means of electrical resistivity tomography (ERT)
(2010-07-27)
Improved understanding of water flow and solute transport through the unsaturated zone is important for the sustainable management of soils. As soils are complex and heterogeneous systems, quantification of the transport ...
Root-restricting layers in German agricultural soils: Extent, cause and management strategies
(2020-10-21)
Subsoil, i.e., soil below 30 cm depth, harbours great amounts of water and nutrients. However, physical and chemical barriers for vertical root elongation may restrict plants from accessing subsoil resources. Such ...
