Study Finds that Regenerative Agriculture Is Undermined by Toxic Pesticide Use   (Beyond Pesticides, September 18, 2019) A new report published by Friends of the Earth (FOE), “Pesticides and Soil Health” highlights healthy soil as a key pillar of regenerative, organic agriculture. FOE focuses in on an often-overlooked aspect to soil health, “that eliminating or greatly reducing toxic pesticides is key to building healthy soils and ecosystems for a healthy planet.”   'Toxic chemicals damage the soil microbiota by decreasing soil microbial biomass and altering the composition of the soil microbiome. Fungi-rich soil improves productivity and increases carbon sequestration capacity, but use of pesticides results in a bacteria-dominant ecosystem. Changes in soil composition also result in “vacant ecological niches, so organisms that were rare become abundant and vice versa.” This unhealthy and imbalanced soil has reduced fertility and resilience, and plants grown in such conditions are more vulnerable to parasites and pathogens.  This degraded soil sequesters less carbon than soil with a diverse array of microbiota.

Neonicotinoid Insecticides: Environmental Occurrence in Soil, Water and Atmospheric Particles  (Chapter 2 of Pesticides book, Avid Science. Renata Raina-Fulton, July 30, 2016) 
'they can partition into the particle phase in the atmosphere or be lost during or subsequent to seeding from soil dust created from planters. Presence of neonicotinoid containing particles in the atmosphere is of concern for direct exposure to bees as well as movement
in the environment such as subsequent deposition into surface waters. Concentrations of neonicotinoids in water, soil and atmospheric particles will be discussed'

New evidence of pesticides in Calgary air, soil  (Bridget Brown, CTV Calgary,  June 10, 2015)   'An environmental testing facility has found pesticides that are expected to dissipate in a matter of days persisting in Calgary’s soil and air for months after lawn and garden season has ended.2,4 D is supposed to have a half-life in the order of two weeks,” he says, “and the last application of 2,4D would be the previous fall. and yet in April, we find it.”'  The team also found  atrazine and Dicamba. 'The amount of Dicamba exceeded provincially regulated safe levels.'    SNAP COMMENT: I hope the lab is still in business and the scientist still employed!

Pesticides found in more than 80% of tested European soils   (PhysOrg,January 18, 2019, CORDIS)    'Pesticide residues were found in 83% of the analysed agricultural soils in 166 different pesticide combinations. The most common mixtures detected at the highest concentrations were the controversial weedkiller glyphosate and its metabolite aminomethylphosphonic acid, followed by the commonly used pesticide dichlorodiphenyltrichloroethane (banned in the EU in 1986), and the broad-spectrum fungicides boscalidepoxiconazole and tebuconazole'  'We are increasingly seeing the negative side of chemically intensive system of food production. Today, 2,000 pesticides with 500 chemical substances are being used in Europe. However, data on how such substances affect soil quality is incomplete and fragmented, and fails to clearly reflect their overall impact on soil systems and human health.'

Multiple Pesticide Residues in Soil Raise Alarm (Beyond Pesticides, November 30, 2018)   A pan-European study. 'A study published this month in Science of the Total Environmenreveals numerous pesticide residues persisting in soil, harming the viability of agricultural lands and increasing risk of off-site contamination...Samples were then analyzed for the concentration of 76 pesticide residues. These 76 pesticides were selected as being most often applied on conventional crops. Eighty-three percent of samples contained varying degrees of pesticide residues, with 25 percent showing one pesticide residue and 58 percent showing mixtures of two or more. Only 17 percent of the tested soils had no pesticide residues detected. More residues detected inhe northern, eastern and western EU regions. Glyphosate was the most widely detected.'  SNAP comment: If anone bothered to look t agricultural soils n Saskatchewan or Canada, widespread soil contamination would be found too. We already know glyphosate and is by-product AMPA persist in our northern soils.
