The efficacy of good practice to prevent long-term leaching losses of phosphorus from an irrigated dairy farm
Phosphorus (P) can be leached from intensive land uses, including grazed dairy farming. There is some evidence to suggest that P-leaching can enrich groundwater, especially where fertiliser or farm dairy effluent P (FDE) ...
The mitigation of phosphorus losses from a water-repellent soil used for grazed dairy farming
Phosphorus (P) losses via surface runoff can be large. Soil water repellency (SWR) occurs in warm and dry conditions. If SWR coincides with P fertiliser applications, the risk of P loss by surface runoff may increase. ...
Using organic phosphorus to sustain pasture productivity: A perspective
Organic phosphorus (P) in grazed pastures/grasslands could sustain production systems that historically relied on inorganic P fertiliser. Interactions between inorganic P, plants and soils have been studied extensively. ...
Likely controls on dissolved reactive phosphorus concentrations in baseflow of an agricultural stream
Purpose: High baseflow phosphorus (P) concentrations increase the likelihood of periphyton blooms. Several physical and chemical factors can control baseflow P concentrations such as hydraulic exchange with groundwater, ...
An assessment of MitAgator: A farm-scale tool to estimate and manage the loss of contaminants from land to water
(American Society of Agricultural and Biological Engineers, 2016)
Land users and managers require decision support tools (DSTs) that enable them to estimate losses of contaminants from land to freshwater. MitAgator is a DST that estimates losses of nitrogen (N), phosphorus (P), sediment, ...
