Oil Field Water OK for Some CA Irrigation
Irrigation with water from oil fields may be safe for a California water district’s crops if the water is diluted and boron-tolerant crops are grown.

Wounding Leaves Produces Sweeter Organic Strawberries
By Radhika Desikan Do you like your fruit to be organically grown or conventionally grown? This has been a choice available to consumers since the first half of the 20th century in response to raised awareness about agriculture’s dependence on synthetic chemicals. With increasing scientific discoveries of novel chemicals that protect and help plants grow, there was also increased knowledge about the possible dangers of having these chemicals in food crops. This resulted in farmers growing crops without the use of agrochemicals, leading to the movement of organic farming. There…

Could Agriculture Save US Water Supply?
By Mackenzie Myers This article is part of a series about key science policy issues. Please use these articles to become an informed voter, ask political candidates about the issues, and put every candidate on record about science. This time of year in California’s Central Valley, it’s easy to see where the Golden State gets its nickname. Golden sun shines on golden grasses of rolling golden hills, parched after so many months without rain, which is unlikely to return for at least several more weeks. Even so, there are signs…

Curing “Plant Blindness” with Botanical Gardens and Farms
By Neha Jain (@lifesciexplore) What was the last plant you saw? Have you ever seen a grain of wheat? How many varieties of rice are there? Although many of us desire a green environment, more and more people, especially urban dwellers, are becoming oblivious to the plants around them—so much so that just over two decades ago, researchers even coined a term for this phenomenon: “plant blindness.” Much of the food we eat today is the result of thousands of years of plant cultivation and breeding by our ancestors. As…

Do We Really Need Fertilizers To Grow Crops?
By Radhika Desikan We all learn that plants can make their own food via a complex process called photosynthesis. However, to make their food, and to grow properly, plants need nutrients (chemicals) such as nitrogen, phosphorus, potassium, and calcium from the soil. Although these chemicals are naturally present in most soils, years of intensive farming have depleted soils of these nutrients. As a result, humans have resorted to using artificial fertilizers, which are basically synthetic nutrients manufactured through a process that uses a lot of energy, and produces a lot…

Space Farming Is More Than Just Plants
In a remarkable new study, scientists studied how plants can grow better in conditions that mimic microgravity in space. This study highlights the prospects of future sustainable space farming, …which may be the answer to long-term feeding of astronauts who need to survive in space.

Honeybees Are Attracted to Fungicides and Herbicides
By Neha Jain @lifesciexplore Whenever you eat fruits, vegetables, and nuts, take a moment to thank honeybees for their pollination services that contribute $17 billion to the US economy each year. In fact, almonds are almost solely dependent on honeybees for pollination. Populations of these much-needed pollinators have mysteriously plunged over the past decade, and many studies suggest a link to the use of neonicotinoid insecticides among other factors such as climate change and disease. Recently, scientists found that honeybees prefer sugar water laced with the fungicide chlorothalonil and the…

Urban Life of Bees: A Pollination-Parasite Trade-Off
By Jonathan Trinastic @jptrinastic Few people would consider cities the ideal home for bees, but what if these dense population centers could provide the means for healthy cohabitation? Scientists from Europe recently examined how bumblebees visit and pollinate flowers across urban and agricultural regions and found that urban areas can have a surprisingly beneficial effect on pollination rates. The reasons behind these results not only provide insight into how cities could be designed to better care for bees but also signal yet another danger of farming monocultures. Urban sanctuary…

GMOs and the Risk to Our Genetic Heritage
By Alex Taylor In 2001, high in the Sierra Norte de Oaxaca mountains of southern Mexico, UC Berkeley graduate student David Quist hiked along some of the world’s oldest cornfields. Quist was sampling cobs for DNA testing, and what he found kicked off a scientific firestorm and brought attention to a subtle threat to the future of global agriculture. In those ancient Mexican corn varieties, Quist detected the DNA signature of genetically modified organisms (GMOs). A living genetic repository Hike down those Oaxacan mountains and into village marketplaces, and you…
