Cyberfarming

City dwellers tend to think of the high-tech revolution as primarily an urban phenomenon--hip office workers thumb-typing messages to each other on their pagers while standing in line for lattes, for example. But the countryside is well on its way to becoming as high-tech as the city, as new technologies relentlessly transform agriculture into something new: cyberfarming. Cyberfarmers use high-tech tools to: gather detailed data on every square metre of their land, select and plant their crops, monitor conditions throughout the growing process, apply precise amounts of water, fertilizer, herbicides and pesticides as needed, and harvest the results at precisely the right time.   Take, for example, the King Family Farms, a 50-acre vineyard in the ...

Are bananas doomed?

Canadians eat approximately three billion bananas a year; it's our favorite fruit. But a recent news story suggests the bananas we enjoy so much could be extinct within 10 years. The villain is a fungus by the ominous name of Black Sigatoka that's spreading out of control through the banana-growing countries of the world, threatening the handful of banana varieties that are the mainstay of the banana industry. These bananas are vulnerable for the same reason they're seedless: they're the descendants of sterile mutants of wild bananas, which are so full of hard seeds they're inedible. Thousands of years ago humans discovered the seedless variety, which propagates by putting out ...

Fruit

 just came back from a vacation that included a brief stay in the Okanagan. Among the treasures from that visit were two containers of delicious fresh apricots and cherries, courtesy of a friend who owns an orchard near Oliver. The amount of fruit produced by the trees of the Okanagan Valley alone is staggering: everywhere you look, it seems, peaches, apples, cherries, grapes and other delectable delicacies are growing. Which, naturally, got me wondering: what is fruit, and how is it grown in such abundance? There are actually three definitions of fruit. According to the strict botanical definition, the fruit of a flowering plant (and only flowering plants, or angiosperms, ...

Seeding

The modern farm is highly mechanized, but the goal of the farmer driving a $100,000 tractor across multiple hectares remains the same as that of a farmer scraping the ground with a pointed stick: a successful harvest. Before you can harvest a crop, though, you've got to plant it. The trick to planting is to put seeds into contact with enough water to cause them to germinate, in soil containing enough nutrients to allow them to grow. When farming first began, farmers simply spread their seeds on any likely-looking patch of ground. Some of the seeds would fall on good soil, and prosper; others might fall on rocky soil and wither away, others might fall among ...

Cattle

My niece collects cows. Well, images of cows, anyway. And she's not the only one. Apparently, cows are hot right now. Personally, I've never been all that enamored of them. My encounters with cows have generally been unrewarding, from the time I tried to milk one (an experience neither of us enjoyed) to the time I helped a veterinarian chase them around a farmyard. Running around a farmyard after a bunch of cows isn't my idea of a good time. You step in stuff. However, I definitely do appreciate the other end products of cows, from milk to leather to steak, and so do most other humans. That's why we've ...

Fertilizer

Just so I'm not operating under false pretenses, let's get one thing straight: I don't garden. I don't seed, I don't weed, I don't plant, I don't compost, and I don't spread manure (this column excepted). My one connection with the plant world is mowing the grass, and I wouldn't do that if I had my druthers. But many people do do all these things. Some of even claim to enjoy it. I don't pretend to understand this obsession with green growing things (and the multi-legged things that eat green growing things), but live and let live, that's my motto. One topic that seems to come up whenever two or ...

Wheat

The most amazing thing about this week's topic isn't the topic itself (though that's pretty amazing); the amazing thing is that I haven't written about it before. "It" is wheat, and how I've managed to go more than three years without mentioning it I can't imagine, in view of the fact it's as inescapable a part of living on the prairies as the wind, and especially in view of the unforgettable (however hard I try) summer I spent at the Weyburn Inland Terminal loading, shoveling and sweeping up the stuff. Despite its ubiquitousness these days, wheat hasn't always grown here. Although it was first cultivated in the Euphrates Valley nearly 9,000 years ago, it didn't exist ...

Biological control of leafy spurge

In 1987, when I was news editor of the Weyburn Review, I journeyed to a small lake near Maxim to photograph beetles infesting the pretty yellow-flowered plants growing on its steep banks (hey, the news business isn't all politicians and other disasters!). Today, I'm told (though I haven't had the opportunity to go see for myself), those pretty yellow flowers are gone. An ecological disaster? Not exactly-- not when the pretty plant in question is one of the most noxious of noxious weeds. In this story, the bugs are heroes, not villains. The plants were leafy spurge, whose stems and leaves are filled with a milky latex harsh ...

Genetic engineering

Though the word "biotechnology" sounds very modern, what it describes has been with us for centuries--if you define it, as one science encyclopedia does, as "using biological organisms, systems or processes to make or modify products." In other words, the first time somebody discovered the wondrous change wrought in grape juice by fermentation, or an excited baker got a little yeast in her dough and saw it swell up (think how brave whoever ate it must have been!), biotechnology was at work. In a broader sense, all agriculture is biotechnology, using biological organisms (plants and animals) to make a product (food). Through the centuries, selective breeding ...
