The potassium paradox: Implications for soil fertility, crop production and human health

In the chemical age of agriculture that began in the 1960s, potassium chloride (KCl), the common salt often referred to as potash, has and is widely used as a major fertiliser in the Corn Belt without regard to the huge soil reserves that were once recognized for their fundamental importance to soil fertility. Three University […]

Steroids can regenerate in aquatic ecosystems

Steroidal substances such as those used in agriculture and pharmaceuticals may be persistent in the environment for longer than previously thought. A team of researchers found that anabolic steroids have a mechanism whereby phototransformation is reversed. “We investigated trenbolone, an anabolic steroid, and found that the photochemical breakdown isn’t the end of its life cycle,” […]

Mystery moss rediscovered

A botanical puzzle more than 150 years old could soon be solved, thanks to a discovery by a second-year botany student in Queensland’s far north. James Cook University student Megan Grixti found a population of Sorapilla papuana, an extremely rare moss, growing on a single tree in remote rainforest near Mount Lewis, west of Mossman. […]

Urban gardens good or bad?

The issues surrounding food production in urban areas are outlined in a paper recently published by Wortman and Sarah Taylor Lovell in the September-October issue of Journal of Environmental Quality. The benefits of urban agriculture are many. Urban gardens are often built on previously unused lots, increasing the beauty and value of the neighborhood. They […]

Cardwell and surrounds

South of Cardwell is the Murray Falls National Park. With a moderate level of fitness you can take a 1.8 km return walk along Yalgay Ginja Bulumi — this road from our forefathers. A journey along this track is guided by the Girramay through the clever use of signage. At the entrance a warning is […]

Out of Africa? New bamboo genera, mountain gorillas, and the origins of China’s bamboos

Hidden away on mountains in the tropics where they provide food for gorillas, just as China’s bamboos provide food for the Giant Panda, are the only two species of African mountain bamboos.

Unscrambling the genetics of the chicken’s ‘blue’ egg

They are the latest foodie fashion and look set to become big business in the baking aisles of all the major supermarkets – the blue egg produced by some chickens is prettier and some say tastier and cleaner-breaking than the traditional brown one – and now, thanks to scientists from The University of Nottingham, we […]

Ancient cycads found to be pre-adapted to grow in groves

Cycads have large, heavy seeds with a fleshy outer coating that suggests they rely on large bodied fruit-eating animals to disperse their seeds. Yet there is little evidence that they are eaten and dispersed by today’s larger-bodied animals, such as emus or elephants. If these plants are adapted for dispersal by a set of animals […]

Sugar is toxic to mice in ‘safe’ doses

When mice ate a diet of 25 percent extra sugar – the mouse equivalent of a healthy human diet plus three cans of soda daily – females died at twice the normal rate and males were a quarter less likely to hold territory and reproduce, according to a toxicity test developed at the University of […]

Maize trade disruption could have global ramifications

Disruptions to U.S. exports of maize (corn) could pose food security risks for many U.S. trade partners due to the lack of trade among other producing and importing nations, says a Michigan State University study. The study, featured in the journal Risk Analysis, didn’t primarily focus on plant disease, population growth, climate change or the […]
