New catalyst uses light to convert nitrogen to ammonia
Northwestern University scientists are the first to develop a catalyst that can perform a remarkable feat found only in nature: take nitrogen from the air and turn it into ammonia under natural conditions. No high temperatures or pressure required. Driven by light, the new method offers promise for a more environmentally friendly fertilizer. Ammonia is the critical component in fertilizer.

Can organic crops compete with industrial agriculture?
An analysis of 115 studies comparing organic and conventional farming finds that the crop yields of organic agriculture are higher than previously thought. Researchers also found that taking into account methods that optimize the productivity of organic agriculture could minimize the yield gap between organic and conventional farming.

Corn Sidedress Nitrogen Rate Test
Fertilizing corn is one of the largest expenses on our farm, and Nitrogen (N) is the biggest contributor to that cost. Over that last few seasons we have changed our N program quite a bit with goals of improving corn yield, more effective application timing, and reducing costs.

Farmers: What Do You Think Of Pollan's Ideas?
Michael Pollan has authored multiple books in defense of fresh foods. He advocates for food grown on small, local farms. But many farmers argue that Pollan's vision contradicts the future of agriculture, and is not practical for all farmers, or consumers.

Dangerous nitrogen pollution could be halved
05/13/2014 - The most important fertilizer for producing food is, at the same time, one of the most important risks for human health: nitrogen. Chemical compounds containing reactive nitrogen are major drivers of air and water pollution worldwide, and hence of diseases like asthma or cancer. If no action is taken, nitrogen pollution could rise by 20 percent by 2050 in a middle-of-the-road scenario, according to a study now published by scientists of the Potsdam Institute for Climate Impact Research. Ambitious mitigation efforts, however, could decrease the pollution by 50 percent. The analysis is the very first to quantify this.

Study shows soil building benefits of organic farming
GREENFIELD, Iowa — Farmers switching to organic crops not only reap premium prices, they also build healthy soil and sequester carbon, according to the results of a study at Iowa State University\'s Neely–Kinyon Research Farm near Greenfield. Kathleen Delate, ISU agronomy and horticulture professor, outlined the results of the Long–Term Agroecological Research, or LTAR, Experiment during a recent field day at the farm. The experiment is one of the longest running replicated comparisons of organic and conventional agriculture in the country. Results from 2002 to 2010 were published in April in Crop Management. The experiment started in 1998 with funding from the Leopold Center for Sustainable Agriculture and is also used as a demonstration plot for USDA studies. \"Farmers interested in transitioning to organic production will be happy to see that with good management, yields can be the same, with potentially higher returns and better soil quality,\" said Delate, who leads the project.

To what extent does organic farming rely on nutrient inflows from conventional farming?
Organic farming is increasingly recognized as a prototype for sustainable agriculture. Its guidelines ban the use of artificial fertilizers. However, organic farms may import nutrients from conventional farming through material exchanges. In this study, we aimed at estimating the magnitude of these flows through the quantification of nitrogen, phosphorus and potassium inflows from conventional farming to organic farming. Material inflows and outflows were collected for two cropping years on 63 farms. The farms were located in three French agricultural districts distributed over a gradient of farming activity defined by both the stocking rate and the ratio of the farm area under arable crops. Our results showed that on average, inflows from conventional farming were 23%, 73% and 53% for nitrogen, phosphorus and potassium, respectively. These inflows were strongly determined by the farm production systems. However, for farms similar in terms of production systems, the inflows also depended on the local context, such as the proximity of organic livestock farms: the reliance of organic farming on conventional farming was lower in mixed than in specialized districts. These results highlight the necessity to quantify the contribution of nutrient inflows from conventional farming when assessing organic farming and development scenarios.

Systemic non-nodular endosymbiotic nitrogen fixation in plants
Non-leguminous crops, e.g. wheat, maize and rice, do not form nodules and are dependant for their nutrition on fixed nitrogen from the soil, or from chemical/nitrogenous fertilizers. The present invention provides non-leguminous plants and leguminous plants, including legumes that fail to nodulate with Rhizobia, with bacteria that enable them to fix nitrogen endophytically. Therefore, the plants contain nitrogen fixing bacteria the bacteria being located intracellularly in living plant cells.
