Little yield impact from excess phosphorus: study
Ohio State researchers emphasize opportunity for cost savings amidst high input prices
Ontario invests $3 million protecting the Lake Simcoe Watershed
Funding offsets Holland Marsh farmer adoption of innovative phosphorus reduction technology
Ontario continues to encourage farmers to adopt technologies reducing phosphorus runoff into local watersheds with a $3 million Farm Washwater Innovation and Stewardship program addressing the Lake Simcoe Watershed.
Making Canada self-sufficient in phosphorus
A proposed project near Hearst could ease this country’s reliance on imports of a diminishing commodity
The demand for increased crop production continues, placing stress on domestic consumption but also in feeding the world. That makes the search for domestic sources of phosphate as much about self-sufficiency as it is food security.
Database tracks worldwide agricultural phosphorus use
Science Notes: Phosphorus scarcity is a concern for countries with limited reserves
Researchers from the University of Maryland Center for Environmental Science have released a first-of-its-kind study quantifying cropland phosphorus budgets around the world. It is expected to help identify regional nutrient management gaps in […] Read more
Critical to account for greater nutrient removal from crops
Adequate baseline P and K levels bring savings opportunities, little yield impact, when fertilizer is expensive
Want to save on potassium and phosphorus fertilizer this year? A joint Ontario agriculture department and University of Guelph analysis from 2015 highlights how growers who meet certain soil fertility […] Read more
Nutrient strategies must reflect Erie watershed’s diversity
Local research and best management practices important to reducing phosphorus movement
When making decisions about best management practices (BMPs) to minimize phosphorus loss to Lake Erie, farmers should consider the variability of the region’s climate and topography as well as the […] Read more
Manitoba soil temperatures allow for spring fertilizer
Winter ban lifted, with cautions
Farmers across Manitoba are now cleared to apply spring fertilizers including livestock manure on their fields, thanks to sufficiently warm soil temperatures, the province said Tuesday. Though the winter nutrient […] Read more
More technology tested for phosphorus removal
The latest innovation will filter water at a pumping station, from tile and surface runoff
The Thames River Phosphorus Reduction Collaborative (PRC) is moving ahead with the testing of additional technologies that intercept and remove phosphorus from agricultural runoff. Phosphorus entering the system contributes to […] Read more
Extract phosphorus derived from dairy waste water
New technology recycles disappearing essential nutrient to ensure that it doesn’t end up where it isn’t needed
Glacier FarmMedia – Researchers in Israel have developed a way to create phosphorus fertilizer from dairy farm waste water. Why it matters: If implemented on a large scale, the process […] Read more
Steel-making byproduct used as field tile filter
Conservation authority hopes to perfect farm-scale system for slag
At farms in South West Oxford and Lucan Biddulph, a byproduct of the steel-making process is being inserted into tile drainage systems, as part of a research project by the […] Read more
