  • Turning field residue into ethanol feedstock

    Darrin Ihnen is looking at corncobs in a new light. Once left on the fields to rot, Ihnen is now harvesting the cobs along with the corn from 4,000-acres on his farm in Hurley, South Dakota - hoping to turn the field waste into income producing feedstock for making ethanol. Typically corn is harvested by a combine that strips the ears from the corn stalks, separates the grain from the ears and ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Crop sensors outdo farmers at choosing nitrogen rates

    Choosing how much nitrogen (N) to put on corn fields isn’t something farmers take lightly. Many factors go into the decision, including past experiences, the timing of application, yield goals, and results from soil tests. Nevertheless, crop sensors can select N rates for corn that outperform those chosen by farmers, according to more than 50 on-farm demonstration projects conducted in ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • Crop gene banks are preserving the future of agriculture. But who’s preserving them?

    As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate ...

  • Earth out of sync rising temperatures throwing off seasonal timing

    A newly hatched chick waits with hungry mouth agape for a parent to deliver its first meal. A crocus peaks up through the snow. Rivers flow swiftly as ice breaks up and snows melt. Sleepy mammals emerge from hibernation, and early frog songs penetrate the night. Spring awakening has long provided fodder for poets, artists, and almanac writers. Even for a notoriously fickle time of sunshine, ...

  • Family farms can be competitive by focusing on conservation and stewardship

    While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...

  • Corn, a Vital Staple Food in Africa

    Africa contributes the least to global warming than any other continent. However, it suffers greatly from some of the more serious impacts of climate changes. The statistics are shocking: Africa emits roughly 4% of greenhouse gas emissions, while the United States emits 23% of the total global greenhouse gasses. Unfortunately, along with Asia, Africa is the region where crop production is the ...

  • Better photosynthesis for a better world?

    There’s no question that plants are better than most other life forms at converting carbon dioxide and sunlight into the sugars that form the basis of our global food web — and eventually, humans’ entire food supply. But fact of the matter is, with conversion rates hovering around 2 percent for our best crop fields, they’re by no means great. Even a slight increase in the ...

  • A hotter planet means less on our plates

    In the Sunday November 22, 2009 issue of Outlook in the Washington Post, Lester Brown discusses the significant implications of food security in the upcoming Copenhagen Conference. As the U.N. climate-change conference in Copenhagen approaches, we are in a race between political tipping points and natural ones. Can we cut carbon emissions fast enough to keep the melting of the Greenland ice ...

  • Peak phosphorus - conserving the world`s most essential resource

    Abstract Phosphorus (P) is one of the three major plant nutrients but it is the scarcest on the planet; at the current rate of exploitation, today's resources will be exhausted in about 70 years; 80% of the extracted P is used as fertiliser. Additional reserves might last another 200 years; when they are exhausted, crop yields will decline rapidly. All living cells require P; it cannot be ...
