Sharing soil knowledge in the 21st Century

By better sharing of soil knowledge between people over a sustained period, we can improve soil condition and function, and improve soil management. Soil scientists and practitioners often work independently of each other, with limited opportunity to learn from each other and share their soil knowledge. At the same time, there is a loss of people with a depth of experience, expertise and local knowledge of soil. Yet we have thought little about how we will capture their knowledge and experience and use it to inform and support the next generation. In a paper recently published in Soil Science Society of America Journal, soil educators and extension agents concluded we must value, capture and share the experience and expertise of scientists and practitioners equally, including: farmers, scientists, educators, extension staff, commercial sector and the public.

Organic farming traps carbon in soil to combat climate change

Organic farms were found to have 26 percent more long-term carbon storage potential than conventional farms. When it comes to mitigating the worst impacts of climate change, keeping excess carbon out of the atmosphere is the prime target for improving the health of our planet. One of the best ways to do that is thought to be locking more of that carbon into the soil that grows our food.

First-ever global erosivity map shows areas most vulnerable to erosion

Understanding erosion is important in quantifying the loss of topsoil for agriculture, as well as the contamination of food and water by sediments. However, erosion is a very complex process. It depends on many factors, including climate, soil type, and vegetation cover. A new map, published in an open-access paper, tries to quantify how much energy is available to erode the land surface on a given spot globally.

3D Soil Hydraulic Database of Europe at 1 km and 250 m resolution

A consistent spatial soil hydraulic database at 7 soil depths up to 2 m has been calculated for Europe based on SoilGrids250m and various 1 km datasets, and pedotransfer functions trained on the European Hydropedological Data Inventory. Saturated water content, water content at field capacity and wilting point, saturated hydraulic conductivity and Mualem-van Genuchten parameters for the description of the moisture retention, and unsaturated hydraulic conductivity curves have been predicted. The derived 3D soil hydraulic layers can be used for environmental modelling purposes at catchment or continental scale in Europe. It is the only EU provides information on the most frequently required soil hydraulic properties with full European coverage up to 2 m depth at 250 m resolution.

How human waste is helping Aussie farmers get the best out of their land

About 180,000 tonnes of biosolids are generated from Sydney’s sewage each year, but authorities are having no troubles with getting rid of it. Biosolids, which is a by-product of the sewerage treatment process, is proving a hit with New South Wales farmers who want to improve soil health and boost yields. Harvested from 23 of Sydney’s sewerage plants, the waste is processed through reactors which also create renewable energy that is fed back into the system.

How 12,000 tonnes of dumped orange peel grew into a landscape nobody expected to find

An experimental conservation project that was abandoned and almost forgotten about has ended up producing an amazing ecological win nearly two decades after it was dreamt up. The plan, which saw a juice company dump 1,000 truckloads of waste orange peel in a barren pasture in Costa Rica back in the mid 1990s, has eventually revitalised the desolate site into a thriving, lush forest.

BonaRes2018 Conference: Soil as a sustainable resource

Berlin, Germany, 26-28 February, 2018.
The conference brings together researchers from all disciplines of soil science to discuss the functionality of soil ecosystems and how to develop strategies towards sustainable soil management. A sustainable bioeconomy requires integration of soil productivity with a wide range of other soil functions including nutrient cycling, carbon storage, water retention and filtering as well as being the habitat of a myriad of organisms and their activities. For sustainable soil management, we need to understand soils at a systemic level and to assess their value in a socio-economic framework. Abstract submission deadline: November 1st, 2017

Assessment, Restoration and Reclamation of Mining Influenced Soils

By Jaume Bech, Claudia Bini and Mariya Pashkevich (Editors). 1st edition published 12 September 2017 by Elsevier, imprint Academic Press, 520 pages, Paperback ISBN: 9780128095881, price paperback EUR 147.66.
This tome covers processes operating in the environment as a result of mining activity, including the whole spectra of negative effects of anthropopressure and the environment, from changes in soil chemistry, changes in soil physical properties, geomechanical disturbances, and mine water discharges. Mining activity and its waste are an environmental concern. Knowledge of the fate of potentially harmful elements and their effect on plants and the food chain, and ultimately on human health, is still being understood. Therefore, there is a need for better knowledge on the origin, distribution, and management of mine waste on a global level.

Biofilms in Plant and Soil Health

Edited by Iqbal Ahmad and Fohad Mabood. Published in September 2017 by Wiley-Blackwell, 568 pages, ISBN: 978-1-119-24634-3, price hardcover: £160.00/€192.00.
Biofilms are predominant mode of life for microbes under natural conditions. The three-dimensional structure of the biofilm provides enhanced protection from physical, chemical and biological stress conditions to associated microbial communities. These complex and highly structured microbial communities play a vital role in maintaining the health of plants, soils and waters. Biofilm associated with plants may be pathogenic or beneficial based on the nature of their interactions. Pathogenic or undesirable biofilm requires control in many situations, including soil, plants, food and water.

Can Soil be brought back to Life?

Can American soil be brought back to life?” This is the question posed in Politico (Sept 13th). The challenges are the same everywhere in the world: over-tilled soil, too much bare soil within crops and between growing seasons, disturbing changes in weather patterns, over-fertilization linked to nitrate pollution in surface and groundwater. “The UN considers soil degradation one of the central threats to human health in coming decades”, writes the author. Human health and soil health seem to go hand in hand. New farming practices such as No-Till which build soil are being introduced and older practices such as cover-cropping and green-manuring are coming back to life.

How to measure and quantify biological soil processes which influence productivity and sustainability has been Woods End Laboratories (Maine, USA) focus for 30 years. The lab believes that measuring soil’s biological activity can provide valuable insight into how soil management practices may be adversely or favorably influencing sustainable productivity, beyond that which is accounted for by nutrient replacement. Well-managed soils which include those with soil-building crop rotations, cover-cropping and reduced-tillage can accumulate natural reserves, such as microbial-biomass and organic-nitrogen, “pools” that support dynamic soil functions, nutrient bio-availability and natural disease suppression. Typical soil tests are not designed to reveal these traits.
Woods End Lab has introduced several new test methods that complement ordinary nutrient tests which enable labs and farmers to evaluate these added factors. One goal is to establish a biological baseline for soil from which one can monitor and optimize management. One important outcome is the potential to reduce the quantity of fertilizer inputs – especially nitrogen. Woods End Lab’s new tests are found in the Solvita line of protocols and include: CO2 respiration (a measure of microbial activity), SLAN (a measure of labile amino-N associated with humus) and VAST (as rapid test for volumetric aggregate stability). 
Numerous research projects and published papers have demonstrated the utility of these tests. Solvita is committed to helping soil laboratories worldwide introduce new, cost-effective tests to aid growers and crop consultants enhance their management.
