On March 11, 2011, Japan experienced the unprecedented Tohoku earthquake. It was the largest in Japan’s history, and created a massive tsunami that impacted Japan’s northeastern coast. A result of the earthquake and tsunami was the meltdown of the Fukushima Daiichi Nuclear Power Plant. This meltdown had immediate and long-term impacts on the area. On … Continue reading How is erosion affecting the recovery of the Fukushima area?
Last year, a group of agronomists and soil scientists toured several locations in San Antonio that highlight some new programs and services. Composting can help reduce waste and solve landfill problems. Urban agriculture can reduce the amounts of food deserts and make good use of open urban land. Let’s look at what San Antonio is … Continue reading How is San Antonio reducing its solid waste?
Lead's use may be – but we still have a lead problem, especially in urban areas. The first extraction of the metal lead from ores was ancient – around 7,000 BCE. In the millennia since, Egyptians have used it in cosmetics, Romans in their pipes, the British in their ammunition, and now every society in … Continue reading Is lead contamination ancient history?
Wetlands are fun places to get muddy, enjoy the outdoors, and listen for birdsongs. They provide important habitat for wildlife, and for recreation.

Wetlands are found at the intersection of earth/soil … Continue reading What’s being done to restore wetlands?
Immediately after the Deepwater Horizon oil spill some immediate questions posed were: how bad is the spill in terms of coastal pollution; and,what new technologies could be brought to bear for environmental quality assessment? To evaluate these questions engineers and spill responders were brought in. Their job was to evaluate new and innovative technologies that … Continue reading Determining the impact of Deepwater Horizon’s spill on soil
April 2020, is the 10th anniversary of the BP Deepwater Horizon oil spill in the Gulf of Mexico. We are dedicating this months’ Soils Matter blogs to the topic of the wetlands and soils, how scientists helped determine and solve some related issues – and where the wetlands are in their recovery. British Petroleum’s Deepwater … Continue reading How did Deepwater Horizon’s spill affect the coastal soils and wetlands in the Gulf of Mexico?
What could be greener than using plants to clean up polluted soil? Phytoremediation, the use of green plants to repair unhealthy soil, has sparked the curiosity of scientists and plant lovers for decades. Plants can do things that people can’t, like pull pollutants out of soil while leaving the soil in place. Why worry about … Continue reading What is phytoremediation?
As outlined in our February 15, 2019 Soil Matter blog, natural soil is uncontaminated. Use by humans, especially in cities, can cause some unintended consequences. Long-term exposure to items like petroleum products, chromated copper arsenate and radon can cause problems for humans – and other plants and animals dependent on healthy soils. Petroleum The most … Continue reading Why are petroleum, chromated copper arsenate and radon bad for the soil?
