In this paper, dynamic modelling of nutrient flows in a local food-energy-water system is presented and applied to a simplified case study.
Modelling of nutrient transport during runoff events (in particular particulate-bound nutrients), is especially important, since the spatial redistribution of nutrients (in addition to water and sediment) can have significant implications for vegetation dynamics in these ecosystems.
Modelling of nutrient-balances can assist in identifying and optimising the effect of suitable management practices on soil N. 40490_2013_5014_MOESM1_ESM.docx Additional file 1: Table S1: Nitrogen concentrations and leaching losses in streams from New Zealand native forests.
In some regions paleolimnological data, historical data and modelling of nutrient load were used to validate their choice of reference sites.
It is apparent that the modelling of nutrient signalling and oxidative stress, to which the current work contributes, is coming to a level of detail that enables it to address interesting questions of life history, metabolic regulation and disease.
Model of nutrient recycling may explain longstanding mystery.
These approaches range from simple lumped input output budget, to detailed process-based, spatially distributed models of nutrient transfers.
This study shows the usage of stream-lateral-dimension aggregation strategy in addressing nutrient distance-decay patterns and developing simple regression models of nutrient loading.
In this study, we implement a process-based model of nutrient cycling to evaluate temporal changes in ecosystem nutrient dynamics of managed and non-managed forest stands.
Most of this loss can be attributed to heat, but it can also be explained by processes such as respiration, growth and reproduction, defecation, and death and decomposition (The Habitable Planet, n.d).. Figure 2 illustrates an idealistic model of nutrient cycling, in which nutrients move from the physical environment (i.e. the inorganic nutrient pool) to living organisms.
