...works like this: grass is a perennial. Rotate cattle and other ruminants across pastures full of it, and the animals' grazing will cut the blades - which spurs new growth - while their trampling helps work manure and other decaying organic matter into the soil, turning it into rich humus. The plant's roots also help maintain soil health by retaining water and microbes. And healthy soil keeps carbon dioxide underground and out of the atmosphere...
...Qaeda is not just under more pressure from the West. It's also under more pressure from fellow Muslims. Across the greater Middle East, notes Jenkins, governments that once took a passive, or even indulgent, view of al-Qaeda have been frightened into action by jihadist attacks on their soil.

In Pakistan, the site of repeated attacks, support...
Harvard’s plans to sell a 62.5-acre parcel of land to the Town of Weston, Mass. have been temporarily derailed after engineers discovered high levels of lead and arsenic in the soil, and the sale—nearly a month overdue—has been put on hold until the University’s cleanup of the land...
While arsenic contamination is typically eliminated by removing affected soil, Harvard is considering “encapsulating” contaminated areas, essentially burying affected soil, Gray said. This option not only costs less but also preserves the site’s aesthetic appeal, as the removal of soil would lead to the uprooting of vegetation. Gray added that the “encapsulating” method is environmentally safe, as long as the land is held in perpetuity as green space...
Kyle Story was pressing through the sandy soil of an orange grove on the evening of Jan. 10, one of the coldest nights in Florida in years, and inside the cab of his four-wheel-drive Chevy pickup truck it was toasty. But the gauge on the rearview mirror warned Story that the outside temperature had dropped to 33°F (0.5°C), just one degree above freezing - and it was only 8:30 p.m. That meant he was in a race to start dozens of irrigation pumps, whose warm water would protect his crop both by insulating...
