Recent research from The James Hutton Institute suggests that hidden threats from the agricultural use of contaminated sewage sludge could be contributing to already diminished poor soil health. The potential harmful effects of these unregulated contaminants on soils have been understudied in recent years. Around 87% of the 3.6
How are data science techniques helping us better understand the microbial universe of the soil? Over-reliance on nitrogen fertilizers is leading to the collapse of soil biodiversity. Yet, some predictions warn that there are only 60 harvests left in the world’s soil because it is so depleted by nitrogen fertilizers.
Soil acts as a carbon ‘sink’, locking in GHGs that would otherwise be released into the atmosphere. Upgrading UK soils, particularly farmland and degraded peatlands, could radically improve their ability to store carbon. The potential of soil to sequester carbon is huge and should be fully maximised.”.
This diverts the wastewater from Spring Creek and allows the soil to act as a natural filter for any chemical residuals that remain in the wastewater (image credit: Heather Preisendanz, Penn State). However, naproxen concentrations detected in effluent were at levels that could pose a low-to-medium risk to aquatic organisms.
Researchers have discovered a biological mechanism that seemingly makes plant roots more welcoming to beneficial soil microbes. If we could use mutually beneficial relationships between plant roots and soil microbes to enhance nutrient uptake, then we could potentially reduce use of inorganic fertilisers.
An electronic nose to sniff out soil health that will deliver results to a farmer’s phone in five minutes is being developed by PES Technologies. The company says it is able to create an aroma fingerprint from gas released by microbes in the soil. Jim Bailey of PES Technology at the Agri-TechE REAP Conference 2023.
CIRIA, the Construction Industry Research and Information Association has commissioned a new research project that aims to produce concise, up to date, interactive guidance on the whole surplus soil management process from ‘cradle to grave’, with Stantec appointed as the project research contractor.
Lead author of the study Jane Lucas measures CO2 production from prairie soil samples in Moscow, Idaho (image credit: Dana Whitmore). Combined stressors could impair soils’ ability to cycle nutrients and trap carbon, says a group from the Cary Institute of Ecosystem Studies.
A new study claims to settle a long-standing debate Over the last decade, researchers have sounded the alarm on soil erosion being the biggest threat to global food security. As world governments moved to implement soil conservation practices, a new debate began: does agricultural soil erosion create a net organic carbon (OC) sink or source?
According to Gemidan, plastic, glass and metal still pollutes the soil – despite PAS 110. Gemidan’s technology produces a food waste substrate that the firm says is virtually 100% free from non-organic contamination.
Venture out to the Miami County Farm Tour to see a slice of farm life and explore an organic lavender farm and a regenerative farmstead. Three new stops have been added this year: Five Mile Farms uses regenerative farming practices that are more environmentally friendly for the soil and the climate.
Industry specialists working on contaminated land are being urged to use the new British Standard BS 10176 for soil sampling. Good soil VOC data begins with good sampling practices. Concerns raised over reliability of old-style VOC testing.
Colm Warren is Chief Executive of Belfast-based Natural World Products (NWP), a firm which converts food and garden waste into organic compost. However, there is significant scope for this figure to be increased with a greater and concerted push from authorities to drive up recycling rates of household organics, including garden waste.
The biomethane industry, policy makers and regulators need to work closely together to fully realise these benefits, prioritising organic waste and residue feedstocks, incentivizing sustainable agricultural production and valorising biomethane co-products (digestate and biogenic CO2).”
By Gauthier Eppe Persistent organic pollutants (POPs) are toxic chemicals that pose a significant threat to human health and the environment. POPs are ubiquitous in our environment (water systems, soil, air and sediments) and they bioaccumulate, passing from species to species through the trophic chain, ultimately ending up in the human body.
CSA enhances soil health and builds climate resilience, while aiming to mitigate greenhouse gas emissions. We evaluate if this sustainable agricultural practice can serve as a climate-smart agricultural practice in terms of food production, soil health, and environmental sustainability. What is biochar?
As far back as 2008 we thought it eco-crazy to dig up knotweed infested soils from one site only to dump it in a landfill site, many miles away. This avoids the environmental and financial costs of consigning vast quantities of otherwise good soil to landfill and importing clean fill.
Anaerobic digestion is a process whereby organic materials such as energy crops, agricultural residues, manures and food waste are broken down by bacteria in the absence of oxygen, generating biogas (mostly a mixture of methane, carbon dioxide and nitrogen). Benefit #5: Soil health AD offers significant benefits in terms of soil health.
Here are seven easy strategies for organic control of pests, weeds and disease that you can try now. Likewise, many from this growing cohort of urban homesteaders have a personal preference for non-chemical and/or organic practices. The post Try 7 organic strategies to control garden pests appeared first on Greenability Magazine.
Soil scientist Neil Fuller launches the Sustainable Landscapes Wolds Programme with East Yorkshire farmers. A five-year collaboration is underway between Yorkshire Water and a group of innovative farmers, who are making a bid to improve water and soil quality on the Yorkshire Wolds. per cent to 6.0
The group seemingly found microplastic pollution in all the soil samples collected along the busy Llanberis Path to the summit of Snowdon in April 2021, which were later subjected to microplastic quantification and identification. This workflow can be used to calculate the volume, size and shape of plastic particles within a sample.
The creation of biochar, a charcoal used as a soil amendment, from Japanese knotweed plant waste is a carbon negative process which harnesses the carbon-scavenging power of Japanese knotweed in a positive way and contributes to the fight against climate change by locking carbon away for thousands of years.
Rivers, for example, though we would expect this to be a catchment-specific issue, said David Tompkins, a soil scientist with Aqua Enviro, during the November event. It allocates actions to stakeholders including the EA, local authorities and organic processors. And not all rivers carry the same load of microplastics.
Another greenhouse gas, nitrous oxide (N2O), is released when synthetic nitrogen fertilizers are applied to soils. N2 Applied is tackling this issue by converting by-products like slurry into a valuable nitrogen enriched organic liquid fertiliser. This reduces the amount of ammonia released whilst eliminating methane emissions.
” Penny Simpson, Environmental Law Partner at law firm Freeths, attempted to place the report in context: The fundamental problem with modern economies is that good intentions to try to address problems as they emerge can, over the long run, lead to a steady accretion of rules and regulations which stifle innovation. .”
In Biogas: Pathways to 2030, WBA details how deploying AD to capture and recycle the billion tonnes of organic wastes generated annually by human activity could play a major part in the fight against climate change. Today, only 2% of this organic matter is treated through AD and transformed into a green gas and a biofertiliser.
This compost system provides a maximum environment for microbes to grow and create rich compost soil that increases soil fertility and helps sequester carbon. The post Learn how to build your own composter appeared first on Greenability Magazine. . – 2 p.m., Sunday, June 13 at the Antioch Urban Growers, 2727 NE 44th St.,
Pyrolysis – heating in the absence of oxygen – produces biochar, a residue of nearly pure carbon, which can be infused into the soil, sequestering carbon indefinitely. The resulting biochar will be used as a safe and transportable organic fertiliser forming part of a circular economy in UK agriculture.
Currently working with 300 poultry farms and with a target of meeting one quarter of the UK demand, the product has been developed by Veolia’s organics team. By converting this unused by-product the new material will boost the circular economy in the farming industry, and has the potential to deliver greater cost savings.
As greenhouse gases (GHGs) bubble up across the Arctic, researchers are trying to identify other trace gases from soil microbes that could shed light on what is occurring in the melting permafrost. The goal is to use sensitive gas detection devices to sample microbial volatile compounds coming out with the methane and CO2 gases.”. “The
With its industrial partners EBRI has developed an innovative technology which thermally converts organic waste into three commercially valuable products, biochar, gas and liquids. When put in the earth, biochar works to improve the soil and enhances plant growth, and also doesn’t decay over a long period of time.
Total organic carbon (TOC) analysis is quickly emerging as one of the most essential tools available for assessing water and soil samples, as it delivers key insights for contamination monitoring, environmental analysis and purification benchmarking.
