Eutrophication

The Benefits of Improved Nitrogen Efficiency

The more time I spend talking to agronomists about fertilizer (it’s a borderline-embarrassing amount of time), the more I realize that increased Nitrogen Use Efficiency (NUE) is the Holy Grail of crop production.  NUE refers to the proportion of applied Nitrogen that is taken up by plants (Bundy 2006) and it has been my observation that inefficient Nitrogen use is a key limiting factor that must be overcome in order for the world to continue feeding itself through the 21st century.

In Search of Sustainable Phosphorous

Blog post by Lisa Dirks -- I attended the Sustainable Phosphorus Summit on February 3-5, where Phosphorus experts from around the globe convened to discuss the future of this essential element to life.  When the average person hears the word they may think of high school chemistry and the periodic table, but the speakers and organizers made it a fun topic, sporting pins that said, “P is for people!” and “Save the P[ee]!“. 

Human Health Effects of Chesapeake Bay Pollution

We've talked in the past about the eutrophication damage that is caused by nitrogen and phosphorous pollution in the Chesapeake Bay, but we haven't given much attention to the health threat this pollution presents to the people living in the Chesapeake Bay watershed area.  Here, Lisa Dirks summarizes the human health implications of excessive N and P pollution and how GreenHarvest™ can help to ameliorate them.
