WebMar 1, 2024 · The Brian Pastures Research Facility is a 2,000ha research site located in the North Burnett Region of South East Queensland, a district renowned for quality agricultural products. The facility is centrally located to some of Queensland's major cattle producing areas, providing ease of access for research scientists, universities and students. WebThe phosphorus retention capacity varies greatly among bogs, fens, and swamps and is concomitant with the amorphous acid oxalate-extractable aluminum and iron content in the soil. However, the phosphorus adsorption potential in wetland ecosystems may be predicted solely from the extractable aluminum content of the soil.
