Performance of a fertiliser management algorithm to balance yield and nitrogen losses in dairy systems
To demonstrate the use of a previously developed fertilisation algorithm and to determine its potential effects on nitrogen (N) losses from grazed pastoral systems, a simulation study was performed using the Agricultural ...
Fractionation and distribution of arsenic in soils contaminated by cattle dip
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 1998)
Soils surrounding cattle dips in Australia are known to be highly contaminated with As and are potentially of major concern to the environment and human health. A study of 11 dip sites in northern New South Wales (NSW) has ...
The potential of mini-ridging for controlling intrarow weeds: Estimating minimum lethal burial depth
Weed management using synthetic herbicides is undergoing a global decline, necessitating a re-evaluation of existing control measures and the development of novel weed management tools. ‘Mini-ridging’ is a non-discriminatory, ...
The effect of irrigation and urine application on phosphorus losses to subsurface flow from a stony soil
Diffuse losses of phosphorus (P) from agricultural land via subsurface flow (viz leaching) can result in degradation of surface water quality. Factors such as irrigation and soil pH can increase the solubility of P and its ...
