Researchers at the University of Illinois have identified key factors affecting phosphorus runoff and developed management strategies to minimize its impact on lakes and streams. The team suggests adopting no-till soil conservation practices, injecting liquid manure and fertilizer into the soil just below the surface.
The study found that while some economically important species like walleye and smallmouth bass decline, others like black crappie and common carp increase in abundance. The researchers conclude that ecosystem recovery is a positive sign, despite trade-offs in managing for certain species.
Phosphorus is essential for life as a building block of nucleic acids and energy transfer molecules. New technologies help scientists study phosphorus cycling in soil, sea, and living organisms to better understand its role in the Earth system.
A large study of 191 nuns found no correlation between phosphorus and protein intake and calcium absorption. The researchers suggested that high protein diets may actually contribute to a negative calcium balance due to increased urinary calcium loss.
A new hybrid of corn with more highly available phosphorus and an enzyme that helps chickens digest the mineral has been developed. Studies have shown a 41% reduction in total phosphorus levels and an 82% decrease in water-soluble phosphorus, which can help mitigate nutrient pollution in waterways.
A cross-sectional analysis of 215 women aged 18-31 found correlations between weight, height, lean mass, and dietary factors like calcium, protein, and phosphorus with various bone mineral measures. Postmenarcheal age was positively correlated with total-body BMD and BMC, while radius BMD was linked to protein and phosphorus intakes.
Purdue University researchers isolate plant genes that enable efficient phosphate uptake, a key finding in addressing global phosphorus scarcity. The discovery may lead to the creation of more efficient phosphorus users and alternative sources of phosphorus.
A Penn State poultry nutritionist is developing strategies to balance chicken diets and minimize manure production, reducing nitrogen and phosphorus waste. The approach involves adjusting feed formulation, using better feed additives, and tailoring feeds to the life cycle of birds.
