Spatial distribution of roots is of paramount importance for nutrient acquisition by crop plants. The objective of this study was to assess the spatial distribution of root length density (RLD), root mass density (RMD), and root morphological paramet

A sampling proficiency test is evaluated to analyze the influence of soil heterogeneity and sampling parameters on sampling error of nutrient contents. The influence of parameters on sampling error was assessed by multiple linear regression, regressi

Assessment of trace element contents in soils is required in Germany (and other countries) before sewage sludge application on arable soils. The reliability of measured element contents is affected by measurement uncertainty, which consists of compon

Currently, potassium (K)- and phosphate (P)-fertilizer recommendation in Germany is based on standardized soil-testing procedures, the results of which are interpreted in terms of nutrient availability. Although site-specific soil and plant propertie

On three fields of arable land of (3–6)×104 m2, simple reference sampling was performed by taking up to 195 soil increments from each field applying a systematic sampling strategy. From the analytical data reference values for 15 elements were est

Diffuse Nitrogen (N) loss from agriculture is a major factor contributing to increased concentrations of nitrate in surface and groundwater, and of N(2)O and NH(3) in the atmosphere. Different approaches to assess diffuse N losses from agriculture ha

Information about root distribution is important for characterization and modeling of water and nutrient uptake, biomass, and yield. Due to the heterogeneous distribution of roots in row crops, the reliability and representativeness of estimates of R

The spatial distribution of root length density (RLD) is important for water and nutrient uptake by plants and biomass allocation in the soil. Experimental root assessment is, however, mostly based on methods that encompass only small fractions of th

Soil micropores that contain water at or below field capacity cannot be invaded by seminal or first-order lateral roots of maize plants because their root diameters are larger than 10 μm. Hence, at soil-water levels below field capacity plant roots
