agriculture

There was a time when a farmer simply tasted a clump of dirt to tell the fecundity of the soil. Now, a wide range of chemical analysis help instruct farmers on the optimal mix of fertilizer, pesticide and water. However, tests on soil samples are expensive and time consuming, and few farmers can afford to waste either time or money. And that's where the satellite imaging comes in.

A second Green Revolution can't come soon enough for UK scientists, who say that their government should invest $3.3 billion in crop research to help feed the world. That world will only grow hungrier, and will require a 50 percent boost in food production over the next 40 years.

For almost two years, the honeybees that support almost all human agriculture have fought a plague right out of a sci-fi movie. Varroa mites, a deadly parasite, have hid in the labyrinthine combs of beehives, feeding off the juices of still-living insects, and causing the the problem we know as Colony Collapse Disorder.

To help our bee allies fend off the alien invaders, the Agriculture Research Service division of the Department of Agriculture has created a new breed of super-vigilant bees that will take the fight to the mites.

Carbon nanotubes have improved existing technologies in fields ranging from electrical circuitry to architecture to materials science. So is it any surprise that when researchers in Arkansas applied the miraculous microscopic structures to tomato seeds, the plants grew faster, stronger, and more plentifully?

You say tomayto, I say tomahto.

You say Miracle-Gro, I say ... pee.

Apparently, human urine works remarkably well as a fertilizer for tomatoes, according to a new study out of Finland.

Plants fertilized with a mixture of stored human urine and wood ash produced 4.2 times more fruit than plants without the pee, the study found. The urine-fertilized tomatoes had more beta-carotene than unfertilized ones, and much more protein than traditionally fertilized plants.

Rice farmers in Asia may no longer need to fear monsoon season's devastating floods. Japanese scientists have identified genes that allow deepwater rice to grow hollow "snorkels" to avoid drowning, and have also introduced those genes into other rice variants.

It’s been said there’s no accounting for taste, but if Japanese researchers have their way, there soon will be. Research initiatives underway in various corners of Japanese agriculture will remove taste from the subjective realm and create objective standards for flavor that consumers can use as a yardstick--without ever having tasted a product at all.

Is your $30,000 bottle of Chateau Petrus Bordeaux truly a rare vintage, or is it just $30 merlot? Counterfeits plague rare-wine auctions, but researchers in Spain have built a handheld "electronic tongue" that detects them instantly. It measures the signature chemicals, acidity and sugar content in a drop of wine (typically one bottle from a case) and runs those against a database of certified vintage wines to catch fakes that might fool human tasters.
