“The farmer works the soil; the agriculturist works the farmer”*…

 

agriculture

 

Like the wheat barons of the 1870s who lived on San Francisco’s Nob Hill, [Stewart] Resnick isn’t of this place. He’s never driven a tractor or opened an irrigation valve. He’s never put a dusty boot on the neck of a shovel and dug down into the soil. He wouldn’t know one of his Valencia orange groves from one of his Washington navel orange groves. The land to him isn’t real. It’s an economy of scale on a scale no one’s ever tried here. He grew up in New Jersey, where his father ran a bar. He came to California in the 1950s to remake himself. Welcome to the club. He remade himself into a graduate of the UCLA law school, a cleaner of Los Angeles buildings, a vendor of security alarms, a seller of flowers in a pot, a minter of Elvis plates and Princess Diana dolls, a bottler of Fiji Island water, a farmer of San Joaquin Valley dirt. He purchased his first 640-acre section in the late 1970s and kept adding more sections of almonds, pistachios, pomegranates, and citrus until he stretched the lines of agriculture like no Californian before him.

At age 81, he’s gotten so big, he doesn’t know how big. Last time he checked, he told me he owned 180,000 acres of California. That’s 281 square miles. He is irrigating 121,000 of those acres. This doesn’t count the 21,000 acres of grapefruits and limes he’s growing in Texas and Mexico. He uses more water than any other person in the West. His 15 million trees in the San Joaquin Valley consume more than 400,000 acre-feet of water a year. The city of Los Angeles, by comparison, consumes 587,000 acre-feet.

Resnick’s billions rely on his ability to master water, sun, soil, and even bees. When he first planted seedless mandarins in the valley 17 years ago, the bees from the citrus orchards around him were flying into his groves, pollinating his flowers, and putting seeds into the flesh of his fruit. He told his neighbors to alter the flight of the bees or he’d sue them for trespassing. The farmers responded that the path of a bee wasn’t something they could supervise, and they threatened to sue him back. The dispute over the “no fly zone” was finally resolved by the invention of a netting that Resnick sheathes around his mandarins each spring. The plastic unfurls across the grove like a giant roll of Saran Wrap. No bee can penetrate the shield, and his mandarins remain seedless.

The control Resnick exercises inside his $4.5 billion privately held company does relinquish to one person: his wife, Lynda, vice chairman and co-owner, the “Pomegranate Queen,” as she calls herself. She is the brander of the empire, the final word on their Super Bowl ads, the creator of product marketing. There’s “Cheat Death” for their antioxidant-rich pomegranate juice [POM] and “Get Crackin’ ” for their pistachios [Wonderful] and “Untouched by Man” for their Fiji water. A husband and wife sharing the reins is rare for corporate America, rarer still for industrial agriculture. He commands his realm, and she commands hers, and he takes care to mind the line. “If he sticks even a toe onto her turf,” says a former business partner, “she gives him a look that sends him right back.”

Together, the Resnicks have wedded the valley’s hidebound farming culture with L.A.’s celebrity culture. They don’t do agribusiness. Rather, they say, they’re “harvesting health and happiness around the world through our iconic consumer brands.” Their crops aren’t crops but heart-healthy snacks and life-extending elixirs. Stewart refers to the occasional trek between Lost Hills and Beverly Hills — roughly 140 miles — as a “carpetbagger’s distance”…

Stewart Resnick’s domain is the densest planting of almonds, pistachios, and pomegranates on earth, making him the biggest “farmer” in the U.S. and the biggest irrigated “farmer” in the world: “A Kingdom from Dust.”

As we contemplate concentration, we might send well-organized birthday greetings to Antoine Laurent de Jussieu; he was born on this date in 1748.  A botanist, he is best remembered as the first to publish a natural classification of flowering plants; much of his system– which was, in part, based on unpublished work by his uncle, Bernard de Jussieu— remains in use today.

“The clearest way into the Universe is through a forest wilderness”*…

 

Forest

 

Consider a forest: One notices the trunks, of course, and the canopy. If a few roots project artfully above the soil and fallen leaves, one notices those too, but with little thought for a matrix that may spread as deep and wide as the branches above. Fungi don’t register at all except for a sprinkling of mushrooms; those are regarded in isolation, rather than as the fruiting tips of a vast underground lattice intertwined with those roots. The world beneath the earth is as rich as the one above.

For the past two decades, Suzanne Simard, a professor in the Department of Forest & Conservation at the University of British Columbia, has studied that unappreciated underworld. Her specialty is mycorrhizae: the symbiotic unions of fungi and root long known to help plants absorb nutrients from soil. Beginning with landmark experiments describing how carbon flowed between paper birch and Douglas fir trees, Simard found that mycorrhizae didn’t just connect trees to the earth, but to each other as well.

Simard went on to show how mycorrhizae-linked trees form networks, with individuals she dubbed Mother Trees at the center of communities that are in turn linked to one another, exchanging nutrients and water in a literally pulsing web that includes not only trees but all of a forest’s life. These insights had profound implications for our understanding of forest ecology—but that was just the start.

It’s not just nutrient flows that Simard describes. It’s communication. She—and other scientists studying roots, and also chemical signals and even the sounds plant make—have pushed the study of plants into the realm of intelligence. Rather than biological automata, they might be understood as creatures with capacities that in animals are readily regarded as learning, memory, decision-making, and even agency.

Plants communicate, nurture their seedlings– and feel stress.  An interview with Suzanne Simard: “Never Underestimate the Intelligence of Trees.”

As we contemplate cultivation, we might recall that it was on this date in 1602 that The Bodleian Library at Oxford formally opened.  (Sir Thomas Bodley had donated over 2000 books in his personal library to replace the earlier Duke of Glouchester’s (Duke Humphrey’s) Library, which had been dispersed.  Bodley’s bequest was made in 1598; but the full collection wasn’t catalogued and made available until this date in 1602, when the Library reopened with its new name, in honor of its benefactor.  Eight years later, Bodley made a deal with the Stationer’s Company– which licensed [provided copyright] for all publications in England– that a copy of everything licensed should be sent to the Bodleian…  making it a Copyright Depository, the first and now one of six in the UK.)

“In the end everything is connected”*…

 

Ectomycorrhizal mushroom Dermocybe-1280x720

A fungus known as a Dermocybe forms part of the underground wood wide web that stitches together California’s forests [source]

Research has shown that beneath every forest and wood there is a complex underground web of roots, fungi and bacteria helping to connect trees and plants to one another.

This subterranean social network, nearly 500 million years old, has become known as the “wood wide web.”

Now, an international study has produced the first global map of the “mycorrhizal fungi networks” dominating this secretive world…

Mycorrhizal ecologist Dr Merlin Sheldrake, said, “Plants’ relationships with mycorrhizal fungi underpin much of life on land. This study … provides key information about who lives where, and why. This dataset will help researchers scale up from the very small to the very large.”…

As we contemplate connection, we might spare a thought for Anders (Andreas) Dahl; he died on this date in 1789.  A botanist and student of Carl Linnaeus, he is the inspiration for, the namesake of, the dahlia flower.

“Behold, I have given you every herb bearing seed, which is upon the face of all the earth”*…

For centuries, people in agrarian societies shared seeds to help each other subsist from year to year. Today, thanks to intellectual property rights and often well-intentioned laws, our ability to share seeds is restricted. Realizing this, food activists, garden enthusiasts, and community leaders are trying to make it easier by making seeds available through libraries. Surely there’s nothing controversial about that, right? Actually, there is…

The fascinating history and controversial– but critical– future of seed collection and sharing: “Despite Hurdles, the Seed Library Movement Is Growing.”

As we reap what we sow, we might send flowery birthday greetings to Dukinfield Henry Scott; he was born on this date in 1854.  A leading authority in his time on the structure of fossil plants, and the author of the classic Studies in Fossil Botany, which greatly popularized the subject, he laid the foundations of paleobotany.

“The earth laughs in flowers”*…

 

The first flower?

With the incredible diversity of flowers that exist today—from pinprick-sized duckweed to the meters-high blooms of a corpse flower—it’s hard to imagine that they all descend from just a single species. Charles Darwin himself wrung his hands over how flowering plants exploded in diversity early in their evolution. Now, researchers have figured out what the ancestral flower might have looked like. The study may help them uncover how flowers took over the world.

Fossils are the surest way to learn about organisms that lived in the past, but these are hard to come by for early flowers: The earliest preserved blossoms date back some 130 million years—at least 10 million years after the time when researchers think the ancestor of all flowering plants was alive. But there is another way to learn about species that are long gone: by taking a careful look at the forms of their modern descendants, and tracing the history of those forms back to the trunk of their family tree.

To that end, dozens of researchers participating in the eFLOWER project amassed data from scientific papers to create the largest database of the structures of modern flowers, like their sexual organs and the layouts of their petals. The analysis included more than 13,000 data points spanning back to a 1783 description by famous evolutionary biologist Jean-Baptiste Lamarck. Combining those data with a DNA-based family tree and information about fossils, the scientists tested millions of configurations of how flowers may have changed through time to determine the most likely structure and shape for the earliest flowers.

Though the team’s reconstructed ancestral flower [pictured above] doesn’t look radically different than many modern flowers, it does have a combination of traits not found today…

Pick (up) the tale in toto at: “The world’s first flower may have looked like this.”

As we cultivate our gardens, we might send fecund birthday greetings to Sidney Walter Fox; he was born on this date in 1912.  A biochemist interested in the biological origin of life, he studied the synthesis of amino acids from inorganic molecules.  He gave the name proteinoid to the protein-like polymer that results from a mixture of amino acids subjected to such considerable heating as would be present during the volcanic primordial earth (in the “primordial soup” as it’s colloquially known).  Fox observed that when proteinoids or “thermal proteins,” are placed in water, they self-organize into microspheres or protocells, possible precursors of the contemporary living cell.  Fox argued that RNA or DNA need not date back to the origin of life; and he showed that proteinoid “microspheres,” as he called them, exhibit growth, metabolism, reproduction (by budding), and responsiveness to stimuli – all properties of life – though without a genetic system.
