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.

Farmers Deserve a Break

Over the last week I had the chance to tour Pennsylvania farm country, speak with members of the farming community and attend the Pennsylvania Farm Show.  I came away from that trip with a new perspective on the challenges that are facing today’s farmers.

Eutrophication Overview - Results of Excessive Nitrogen & Phosphorous Runoff (PHOTOS)

Special thanks to Lisa Dirks for contributing this blog post.  Lisa is The GreenHarvest Group's Research Manager. She holds a BS in Biology and MS in Sustainability from Arizona State University.

Eutrophication occurs when bodies of water are polluted by high concentrations of nutrients, especially phosphates and nitrates. 

A Tip for Making Biochar - What NOT to Do

I came across a fairly disturbing "official" biochar tutorial video and felt the need to share it here.  It’s a couple years old, but still serves as a good guide for what not to do.

GreenHarvest Group to Present at DC Entrepreneurship Week

The GreenHarvest Group is having a great time attending DC Entrepreneurship Week events this week.  It's rare to have this kind of opportunity to meet in an informal setting with entrepreneurs, investors and service providers -- a great forum for exchanging new ideas.

Avoiding the Crash: The Importance of Soil Organic Matter

In 2005 Alexandra Bot and Jose Benites of the Food and Agriculture Organization of the United Nations (“FAO”) published a detailed and insightful Soils Bulletin entitled “The Importance of Soil Organic Matter: Key to drought resistant soil and sustained food production.”  The study goes into great detail defining soil organic matter (“SOM”) and outlining its importance as the sine qua non of healthy agro-ecosystems.

An introduction to GreenHarvest™

More than a fertilizer and more than a soil amendment, GreenHarvest™ is a new, natural healthy-growth compound that yields significant and sustainable economic and environmental benefits to all farmers and plant-growers. GreenHarvest™ is different because it can unlock the rich stores of organic matter found in unburned coal that are usually inaccessible to plants and soil.
