Paper mill waste may be just right for reclaiming mineland
Paper mill waste can safely be applied at a rate three times higher than the typical rate in Ohio, to reclaim soils of surface-coal mined areas. Agricultural Research Service (ARS) soil scientist Martin J. Shipitalo found that a 300-ton-per-acre application rate had many benefits, and did not result in major additional negative effects on runoff water quality compared to the standard ...

Simple method to estimate soil carbon stocks in grassland
Storage of carbon in soil helps to keep land fertile and regulates the climate, and is therefore an important ecosystem service. However, mapping of soil carbon stocks currently uses unreliable measures. This study used data from a national survey of English grasslands to show that soil carbon stocks can be accurately predicted using simple measures of soil and climatic conditions. Two to three ...

Eijkelkamp Soil & Water measures water quality for Dutch Water Board
Eijkelkamp Soil & Water recently installed two measuring buoys in the Berkel river at the request of the Rijn en IJssel Water Board. At the beginning of November, waste water from a factory nearby ended up in the Berkel river due to a breakage in a pressure pipe. Rijn en IJssel Water Board started a major cleaning of the Berkel river. Before, during and after the cleaning, Eijkelkamp Soil ...

Climate change could worsen effects of pollution on plants
Emissions from large point sources of pollution, such as heavy industry, have a detrimental effect on the plants growing in the local area. A new study suggests that predicted increases in global temperatures as a result of climate change may worsen the harmful effects of aerial pollution on plant diversity in susceptible areas. Researchers from Finland examined the effects of local, severe ...

With proper care, contaminated urban soils are safe for gardening
A six-year study by Kansas State University researchers indicates that crops grown in contaminated urban soils present little to no risk for people eating those crops when gardeners have followed best practices. The findings are significant for urban and suburban gardeners, who according to a 2012 estimate from the U.S. Department of Agriculture, provide about 15 percent of the world's food, ...

The Changes Biochar Brings to Soil Remediation
In the intricate web of environmental concerns, soil contamination emerges as a substantial challenge with far-reaching consequences. The detrimental impact of pollutants on soil quality and plant health necessitates innovative solutions. Enter biochar, a potent amendment derived from the pyrolysis of organic materials, which not only fosters soil remediation but engenders transformative changes ...

Harmful polycyclic aromatic hydrocarbons removed from soil using wastewater sludge and polyacrylamide
Wastewater sludge is widely used to remove toxic polycyclic aromatic hydrocarbons (PAHs) from soil, and yet the mechanisms underlying this process remain unclear. A new study reveals the extent of PAH removal following different treatments, and could provide a useful resource for those looking to diminish the effects that these pollutants have both on people and on the environment. PAHs have ...

The Importance of Soil Sampling
Soil sampling and analysis can provide useful information about the chemical and physical conditions of soil in a specific location. This information can be used to optimize plant growth, assist in solving soil-related problems, or determine the extend of contamination for a remediation plan. For agriculture, soil sampling results can indicate problems that may include soils having excess ...

Scientists map soils on an extinct American volcano
Union County New Mexico is a landscape of striking diversity. Out of expansive rangelands rise sporadic yet majestic cinder cone volcanoes and mesas preserved by basalt, part of the Raton-Clayton Volcanic Field. Capulin volcano, formed approximately 62,000 years ago, is the youngest volcano in the field. The cone rises 396 m from the plain, reaching an altitude of 2,495 m above sea level. The ...
