If we were to prevent a Malthusian catastrophe, we’d better figure out a way to boost crop yield to keep feeding the planet’s growing population. Gertjan Meeuws and other bioengineers of PlantLab have found an answer: a greenhouse where every aspect of the growing condition is controlled, where climate (or even the Sun) is not a factor at all.

In their research station, strawberries, yellow peppers, basil and banana plants take on an eerie pink glow under red and blue bulbs of Light-Emitting Diodes, or LEDs. Water trickles into the pans when needed and all excess is recycled, and the temperature is kept constant. Lights go on and off, simulating day and night, but according to the rhythm of the plant — which may be better at shorter cycles than 24 hours — rather than the rotation of the Earth. [...]

Sunlight is not only unnecessary but can be harmful, says Meeuws. Plants need only specific wavelengths of light to grow, but in nature they must adapt to the full range of light as a matter of survival. When light and other natural elements are manipulated, the plants become more efficient, using less energy to grow.

"Nature is good, but too much nature is killing," said Meeuws, standing in a steaming cubicle amid racks of what he called "happy plants."

Scientists have just discovered that the slime mold is even cannier than previously thought: it can also "farm."

Research described in Nature shows that a third of these spores contain some of the bacteria to grow at the new site.

Food management has been seen in animals including ants and snails, but never in creatures as simple as these.

The behaviour falls short of the kind of "farming" that more advanced animals do; ants, for example, nurture a single fungus species that no longer exists in the wild.

But the idea that an amoeba that spends much of its life as a single-celled organism could hold short of consuming a food supply before decamping is an astonishing one.

More than just a snack for the journey of dispersal, the idea is that the bacteria that travel with the spores can "seed" a new bacterial colony, and thus a food source in case the new locale should be lacking in bacteria.

1. Chris Stevens of New Richmond, Wisconsin grew a pumpkin this year that weighed in at 1,810.5 pounds -considerably bigger than the previous world-record pumpkin that weighed 1,725 pounds. The big pumpkin was weighed at the Stillwater Harvest Fest in Stillwater, Wisconsin Minnesota last weekend. How did he grow a pumpkin that big? Stevens has a 10,000-square-foot pumpkin patch, in which he grows only one pumpkin per vine. He shades the fruit from the sun, and feeds the vines cow manure, fish emulsion and seaweed.

2. Competitive pumpkin growing really began with William Warnock of Ontario. He grew the Rennie’s Mammoth variety of pumpkins, which were billed as capable of growing to over a hundred pounds. However, Warnock’s pumpkins were much bigger. In 1900 and 1904 he produced fruits that weighed over 400 pounds! His 403 pound world record set in 1904 stood for 76 years. See Warnock’s pumpkins here.

3. The most common variety of pumpkin grown for world-record competitions is the Atlantic Giant, which produces the largest fruit of any plant in the world. The variety was first cultivated by Nova Scotia farmer Howard Dill in 1976. It was Dill who finally broke Warnock’s big pumpkin record in 1979, and grew record-setting pumpkins for several consecutive years afterward. The Dill family still sells the record-breaking seeds.

4. During the last few years of the 20th century, the competitive pumpkin community was rocked by cheating, scandals, and infighting -enough to power a soap opera. The main governing body of the competitions was the World Pumpkin Confederation. A split in the membership led to the creation of the Great Pumpkin Commonwealth, which now oversees official weigh-ins.

5. The first pumpkin that weighed over a thousand pounds was grown in 1996 by Paula and Nathan Zehr of Lowville, New York. Their record-breaking pumpkin weighed an astounding 1,061 pounds, which won the couple a $50,000 prize for reaching the 1,000-pound milestone. Since then, half-ton pumpkins have become “common”. The world record for large pumpkins has been broken every year this decade, except for 2008.

Social networking technology has contributed to the spread of a new group activity: crop mobbing.  In a modern-day equivalent of barn-raising, groups of young farmers and city-dwelling locavores descend on farms to offer their labor without expectation of compensation other than a hearty meal.  They focus their efforts on family-owned organic farms.  Not everyone is enthusiastic about the phenomenon:

Some dismiss crop mobs as urbanites playing at farming, a hands-on variation of the popular “Farmville” Facebook game. Pamela Riney-Kehrberg, history professor at Iowa State University, likened crop mobs to “agricultural tourism.”  “You go in, spend a nice weekend, get your fingers a little dirty. It’s nice but not a significant contribution to agriculture,” she said.

Supporters would vehemently disagree, noting that the experience offers networking for small farmers and an interesting experience for the “agricurious.”  The phenomenon began two years ago in North Carolina, and has now spread to other states.

This month, Mr. Goltstein asked state regulators to let him pop the bubbles. He said he and his 19-year-old son would slice them open with a knife from a paddleboat.

Bruce Palin, assistant commissioner for the office of land quality at the state environmental agency, said officials were considering the idea. But, he added, “not knowing how much volume of gas is there and how much pressure is on it, we’re concerned with just cutting a hole.”

Last year, a hog farmer in Hayfield, Minn., was launched 40 feet into the air in an explosion caused by methane gas from a manure pit on his farm. He sustained burns and singed hair.

Mr. Goltstein’s attorney, Glenn D. Bowman, acknowledged that the potential existed for an explosion: “We’re aware of that sort of common physics issue,” he said.

The Goltsteins filed for bankruptcy last month. Link -via Digg

The Nolan family’s Laurel Valley Creamery got it’s start in 2005 when they purchased farmland belonging to Nick’s grandparents in an attempt to carry on their family farming tradition. Their goal now is to create a successful cheese business and also help people renew their relationship with food production. Nick and Celeste firmly believe that by turning grass into cheese there are rewards far greater than just filling stomachs.

The documentarians are hoping to raise money to finish the film and have it screened for next year’s awards. As the Thomas Jefferson quote rightly states: “Cultivators of the earth are the most valuable citizens.” Aside from Farmville, interest in farming in the United States seems to be going the way of the drive-in movie. This kind of project brings hope for future farmers.
