Interactive comment on “Nitrate leaching from short-hydroperiod floodplain soils” by B. Huber et al

centration. We did this because it is well established that the FC is driven by soil texture. However, to avoid confusion and to focus on our findings we removed the term “soil texture” when explaining the driving factors and used FC only. We remind that field capacity (crosses in Figure 4) were determined with the measurements of the matric potential and soil moisture from the relevant depth (...

Long-term fate of nitrate fertilizer in agricultural soils is not necessarily related to nitrate leaching from agricultural soils.

Accounting for the fate of inorganic N fertilizer in agricultural systems is critical to sustainable production. Sebilo et al. (1) provide a unique long-term record of NO3 fertilizer fate that demonstrates N molecules from a discrete fertilizer application are transferred to soil organic matter (SOM) and subsequently mineralized over the course of approximately 100 y, during which they contribu...

Atrazine leaching from biochar-amended soils.

The herbicide atrazine is used extensively throughout the United States, and is a widespread groundwater and surface water contaminant. Biochar has been shown to strongly sorb organic compounds and could be used to reduce atrazine leaching. We used lab and field experiments to determine biochar impacts on atrazine leaching under increasingly heterogeneous soil conditions. Application of pine ch...

Quantification of Nitrate Leaching from Forest Soils on a National Scale in the Netherlands 813 Quantification of Nitrate Leaching from Forest Soils on a National Scale in the Netherlands

To evaluate the effects of nitrogen (N) emission policies, reliable information on nitrate concentrations and leaching fluxes from forest ecosystems is necessary. Insight into the regional variability of nitrate concentrations, to support local policy on emission abatement strategies is especially desirable. In this paper, three methods for the calculation of a spatial distribution of soil nitr...

Reduced nitrate leaching and enhanced denitrifier activity and efficiency in organically fertilized soils.

Conventional agriculture has improved in crop yield but at large costs to the environment, particularly off-site pollution from mineral N fertilizers. In response to environmental concerns, organic agriculture has become an increasingly popular option. One component of organic agriculture that remains in question is whether it can reduce agricultural N losses to groundwater and the atmosphere r...
