Calculation Methods of Total Nitrogen and Total Phosphorus Distribution in Pig Manure Fractions

open access: yesИнженерные технологии и системы, 2022
Introduction. The study aims to develop and test a comprehensive calculation methodology in a case study of pilot pig complexes to verify reliability of estimates. The methods are required for reliable tracking of the nutrients flow at the farm level and

Nutrient Loadings to Utah Lake from Precipitation-Related Atmospheric Deposition

open access: yesHydrology, 2023
Atmospheric deposition (AD) is a less understood and quantified source of nutrient loading to waterbodies. AD occurs via settling (large particulates), contact (smaller particulates and gaseous matter), and precipitation (rain, snow) transport pathways ...

The total phosphorus budget of a peat‐covered catchment [PDF]

open access: yesJournal of Geophysical Research: Biogeosciences, 2016
AbstractAlthough many studies have considered the carbon or greenhouse gas budgets of peat ecosystems, only a few have considered the nutrient budget of peat soils, and this, in turn, has limited the ability of studies to consider the impact of changes in climate and atmospheric deposition on the phosphorus budget of a peat soil.

Prediction of total phosphorus in reservoir cascade systems

open access: yesEnvironmental Monitoring and Assessment, 2023
Abstract Reservoir cascades have attracted the attention of scientists worldwide. The present study investigates the cascade of five reservoirs (R1, R2, R3, R4 and R5) along a 192 km water channel system located in the State of Ceará, in the Brazilian semiarid region. This cascade system was implemented in 2012 to promote water availability and

Total Value of Phosphorus Recovery

open access: yesEnvironmental Science & Technology, 2016
Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication. To reconcile the simultaneous shortage and overabundance of P, lost P flows must be recovered and reused, alongside ...

Prediction of Total Phosphorus Concentration in Macrophytic Lakes Using Chlorophyll-Sensitive Bands: A Case Study of Lake Baiyangdian

open access: yesRemote Sensing, 2022
Total phosphorus (TP) is a significant indicator of water eutrophication. As a typical macrophytic lake, Lake Baiyangdian is of considerable importance to the North China Plain’s ecosystem.
