Calculating agriculture's phosphorus footprint
Date:4/13/2010

tial environmental, economic and social problem for that part of the world.

"This is a particularly relevant and important topic in the light of the increasing global population since high quality P reserves are diminishing and the cost of fertilizers are escalating rapidly with few options available to increase fertilizer phosphorus use efficiency," the team says.

There are various approaches to improving the position of phosphorus in food production and security, Lott and colleagues suggest. More effort must be made to combine all possible factors to increase the supply of our most important cereal and legume grain/seed crops in an efficient and environmentally sustainable way, they explain. That means optimising the use of phosphorus fertilizers, using selective breeding and genetic modification to produce crops that require less phosphorus depending on whether they are destined for animal feed or human consumption. Most of all, improving agricultural and governance practices can all play important roles in improving food security, in general.
