“…In the absence of any additional stressor, the inhibition of these symbiotic N-fixers is transient, and not expected to affect yields [186]. Some recent reports indicate the potential for indirect effects of glyphosate via its complexation with trace nutrients resulting in increases in pathogenic soil microorganisms, perhaps due to stressed plants [187,188]. However, there is a lack of consensus in the literature on the potential for glyphosate to select for soil pathogens [189].…”

Understanding and Enhancing Soil Biological Health: The Solution for Reversing Soil Degradation

Our objective is to provide an optimistic strategy for reversing soil degradation by increasing public and private research efforts to understand the role of soil biology, particularly microbiology, on the health of our world's soils. We begin by defining soil quality/soil health (which we consider to be interchangeable terms), characterizing healthy soil resources, and relating the significance of soil health to agroecosystems and their functions. We examine how soil biology influences soil health and how biological properties and processes contribute to sustainability of agriculture and ecosystem services. We continue by examining what can be done to manipulate soil biology to: (i) increase nutrient availability for production of high yielding, high quality crops; (ii) protect crops from pests, pathogens, weeds; and (iii) manage other factors limiting production, provision of ecosystem services, and resilience to stresses like droughts. Next we look to the future by asking what needs to be known about soil biology that is not currently recognized or fully understood and how these needs could be addressed using emerging research tools. We conclude, based on our perceptions of how new knowledge regarding soil biology will help make agriculture more sustainable and productive, by recommending research emphases that should receive first priority through enhanced public and private research in order to reverse the trajectory toward global soil degradation.

“…We became aware that glyphosate use on crops such as maize necessitates an increased application rate of nitrogen fertilizers, because glyphosate disrupts the uptake of nitrogen by plants [23]. We also propose that glyphosate disrupts the soil bacteria, leading to changes in the way nitrogen is handled in the soil.…”

There has been considerable international study on the etiology of rising mental disorders, such as ADHD, in human populations. As glyphosate is the most commonly used herbicide in the world, we sought to test the hypothesis that glyphosate use in agriculture may be a contributing environmental factor to the increase in healthcare utilization among individuals with diagnosed ADHD.State estimates for glyphosate use and nitrogen fertilizer use were obtained from the USGS. We queried the Healthcare Cost and Utilization Project net (HCUPNET) for state-level hospitalization discharge diagnosis data on all patients for all-listed ADHD cases from 2007 to 2010. The least squares dummy variable (LSDV) method and within the method using two-way fixed effects was used to elucidate the relationship between glyphosate use and all-listed ADHD hospital discharge diagnoses.A 1-kg increase in glyphosate use in one year positively predicts state-level all-listed ADHD discharge diagnoses the following year (coefficient = 5.54E-08, p<.01). A study of the effects of urbanization on the relationship between glyphosate use and ADHD indicates that the relationship is marginally significantly positive in urban U.S. counties (p<.025). Furthermore, total glyphosate use is strongly associated with total farm use of nitrogen fertilizers from 1992 to 2006 (p<.001).Glyphosate use is a significant predictor of state healthcare utilization for ADHD, with the effect concentrated in urban U.S. counties. We draw upon the econometric results to propose unique and exploratory mechanisms, borrowing principles from soil and atmospheric sciences, for how glyphosate-based herbicides may be contributing to the rise of ADHD in all populations.

“…Several factors associated with the cultivation of herbicide-resistant GM crops may contribute to the increased use of pesticides and losses in productivity, including biological vulnerability, weed resistance, and decreased soil fertility 14,[21][22][23][24][25][26][27][28][29][30] .…”
