Increased population leads to land use (LU) changes from natural to urban and agricultural LU. These disturbances not only decrease the natural treatment potential but they also worsen surface water quality (SWQ). The aim of this review is to assess studies about impacts of anthropogenic LU changes on levels of nutrient concentrations in surface waterbodies, highlighting the important parameters needed for an integrated simulation. The results reported in the literature are not always fully consistent. These contradictory results can sometimes be explained by field measurements under different climatic conditions, different features of landscapes, air deposition rates on ground surfaces, and groundwater flow interactions with surface water. Integrated modelling has been suggested to overcome these inconsistencies. Physical-based and empirical models are the most popular approaches for LU-SWQ studies. Generally, anthropogenic LU such as agricultural and urban areas usually enhances nutrient concentrations much more than natural lands such as forest and barren. Developing sustainable metropolitan areas instead of rural areas, establishing high-standard wastewater treatment plants, and practicing efficient fertiliser application would ameliorate the poor nutrient conditions in SWQ. Riparian vegetation, grassed swales, and construction of artificial wetlands as buffer zones are the most promising natural water quality control measures.

“…Mixing of soil through tillage or soil inversion may reduce the risk of nutrient loss from top soil layers through surficial processes by reducing nutrient concentrations at the soil surface (Vu et al 2009) and in the soil water at the surface (Nash et al 2015). Soil amendments to aid P retention could also be incorporated at the time of tillage (e.g., Summers et al 1996).…”

“…Indeed, this sort of 'strategic tillage' is increasingly considered as beneficial for minimum tillage cropping systems (Dang et al 2015), which also accummulate P in the top 5 mm of soil (Vu et al 2009). However, the reduction in nutrient stratification from tillage or soil inversion will dissipate over time (Nash et al 2015). For instance, McLaughlin et al (1990) rotary-hoed the top 100 mm of soil under an annual pasture, applied 250 kg ha -1 year -1 of superphosphate, and then cut and removed plant shoots annually.…”

Pronounced surface stratification of soil phosphorus, potassium and sulfur under pastures upstream of a eutrophic wetland and estuarine system

High concentrations of nutrients in surface soil present a risk of nutrient movement into waterways through surface water pathways and leaching. Phosphorus (P) is of particular concern because of its role in aquatic system eutrophication. We measured nutrients under annual pastures on a beef farm and a dairy farm in the Peel–Harvey catchment, Western Australia. Soils were sampled in 10-mm increments to 100mm depth in March, June and September. Plant litter contained approximately 300–550mg kg–1 Colwell-extractable P. Extractable soil P was strongly stratified, being approximately 100–225mg kg–1 (dairy) and 50–110mg kg–1 (beef) in the top 10mm and <40mg kg–1 at 40–50mm depth. Total P and extractable potassium were also highly stratified, whereas sulfur was less strongly stratified. Shoot nutrient concentrations indicated that nitrogen was often limiting and sulfur was sometimes limiting for pasture growth: concentrations of P were often much greater than required for adequate growth (>4mg g–1). We conclude that high P concentrations at the soil surface and in litter and shoots are a source of risk for movement of P from farms into waterways in the Peel–Harvey catchment.
