High-frequency measurement of Total Phosphorus and Total Reactive Phosphorus in the Kervidy-Naizin catchment (2016-2023)

This dataset contains high-frequency measurements of Total Phosphorus (TP) and Total Reactive Phosphorus (TRP) in the Kervidy-Naizin catchment https://agrhys.rennes.hub.inrae.fr/. Kervidy-Naizin is part of the environmental research observatory Aghrys, where several environmental compartments – hydrosphere, pedosphere, biosphere – and farming practices have been monitored since 1990 (Fovet et al., 2018). Here, we describe the high frequency data measured by the bankside analyser Hach-Lange Sigmatax-Phosphax from April 2016 to September 2013, and present a comparison with laboratory analysis of grab samples collected at the same site.
