Mitigating NO3− pollution requires an understanding of the hydrological processes controlling contaminant mobilisation and transport, particularly in agricultural catchments underlain by Pleistocene glacial deposits. Focusing on Wensum catchment East Anglia, UK, precipitation (n = 20), stream water 50), field drainage 22) groundwater 84) samples collected between February–March 2011 April–September 2012 were variously analysed for stable isotopes (δ2HH2O δ18OH2O), dual-isotopes (δ15NNO3 δ18ONO3), residence time indicators (CFCs SF6) hydrochemical parameters. The suggested a component modern (post-1960) throughout sequence deposits that corresponds with penetration NO3−.

Analyzing the Impacts of Climate Change on Ecosystem Services Provided by Apple Orchards Using a Process-Based Model

In this paper, we used a fruit tree model, QualiTree, to analyze the impacts of climate change on ecosystem services provided by apple orchards. To do this, blooming model was parameterized simulate date basis data, and QualiTree supplemented with nitrogen processes in soil module describing resource input (irrigation, mineral organic fertilization), transfer (water nitrogen) metabolic transformation-immobilization (mineralization, (de)nitrification).

Soil availability, fertility, drainage depend more strategy than severity. new functions broadened its predictive capabilities allowed better understanding service delivery orchards varying conditions.
