Silicon’s Role in Rice Production

Silicon (Si) is the second most abundant element of the Earth’s crust after oxygen. It has long been neglected by ecologists, as it is not considered an essential nutrient for plants. However, research in recent years shows that it is beneficial for the growth of many plants, including important crops such as rice, wheat and […]

Book Review: Chasing the Red Queen ─ The Evolutionary Race Between Agricultural Pests and Poisons

by Andy Dyer, reviewed by Chris Walters It’s not often that satirical fiction offers a nearly perfect illustration of a scientific principle. Yet Lewis Carroll pulled it off in Through the Looking-Glass when Alice mentions to the Red Queen that running fast generally gets you someplace, at least in Alice’s experience. “‘A slow sort of […]

Natural Plant Toxins Aid Bees

Researchers studying the interaction between plants, pollinators and parasites report that in recent experiments, bees infected with a common intestinal parasite had reduced parasite levels in their guts after seven days if the bees also consumed natural toxins present in plant nectar. In this early and most comprehensive study of its kind, researchers at the […]

Plant Communities Beat Monocultures

Although monocultures can be cultivated efficiently, they are anything but sustainable: environmental damage to soil and water caused by monoculture cultivation is becoming increasingly evident, even beyond in-the-know sustainable farming circles. Despite their disadvantages, however, monocultures remain the principal crop form and are often regarded as the sole possibility for achieving higher yields in plant […]

Diversified Farming Better for Wildlife

A study by scientists at Stanford and the University of California, Berkeley, published in Science, shows that evolutionarily distinct species suffer most heavily in intensively farmed areas. They also found, however, that an extraordinary amount of evolutionary history is sustained in diversified farming systems, which outlines a strategy for balancing agricultural activity and conservation efforts.

Cover Crops for Pest Management

Two small farmers in Florida are partnering with University of Florida Extension to determine how cover crops can be used to manage insect pests. In a newly funded Southern Sustainable Agriculture Research & Education On-Farm Research Grant, “Establishing and Evaluating Selected Cover Crops on Small Farms to Increase the Impact of Beneficial Arthropods on Crop […]
