Urban Gardeners Can Take Simple Precautions to Avoid Contaminants

May 14, 2015 – Green thumbs, do not fret. Pockets of soil in urban areas are still available for the increasingly popular practice of urban gardening.

And while the proximity of these soils to pollution and industry can increase levels of contamination by harmful compounds, some scientists have found that the

Grant Funds Research on Use of Treated Wastewater for Crops

RIVERSIDE, Calif., April 23, 2015 – Researchers at the University of California, Riverside and The Hebrew University of Jerusalem have launched a two-year study of the use of treated wastewater in agriculture, a study they hope will lead to viable and cost-effective regional water reuse policies.

Ruling Out Dust

Ruling Out Dust

Dust control is a sensitive issue for public and commercial projects. Whether the concerns are related to health problems or to safety and quality of life, companies that create dust or cause soil erosion are held responsible—and liable—for activities that violate government regulations.
However, there are many effective products and services
available

Nitrogen in a Mo Fo Lo Po World

Nitrogen is a critical element to growing healthy food. It’s a nutrient that helps plants grow. It’s the elemental backbone of proteins. However, managing nitrogen levels in soils has created debate over the decades. Recently, a group of scientists, industry representatives, farmers, and government and non-government organization members met to

Study Finds Soils Retain Fukushima Radiation

March 24, 2015 – Radiation suddenly contaminates the land your family has farmed and lived on for generations. Can soil play a role in protecting crops and human health? Research in Fukushima, Japan may lend an answer. On March 11, 2011, a magnitude 9.0 earthquake and tsunami caused wide spread
