Probing P losses from Midwestern crop fields

Surface runoff is generally considered to be the most significant source of that phosphorus. But studies by two U.S. Department of Agriculture (USDA) scientists show that underground tile drains—commonly used by Midwestern farmers to drain excess water from crop fields—are also major contributors of phosphorus.


New data suggest resilience of the planet is now at risk

Almost half of the processes that are crucial to maintaining the stability of the planet have become dangerously compromised by human activity. That is the view of an international team of 18 researchers who provide new evidence of significant changes in four of the nine systems which regulate the resilience of the Earth. One of the systems which has been seriously affected is the nitrogen-phosphorus cycle.

Availability of phosphorus in manure applications to soil

The total phosphorus content in manure varies depending on the animal species, age, diet, and how the manure has been stored. Concentration of phosphorus in some manures may be up to 80 to 90 lbs P2O5 per ton (some poultry manures, for example), whereas other manure may contain as little as 4 lbs P2O5 per ton. It will require a laboratory analysis to know for sure.
