Agriculture in the boreal and Arctic regions is perceived as marginal, low intensity inadequate to satisfy needs of local communities, but another perspective that northern agriculture has untapped potential increase supply food even contribute global system. Policies across jurisdictions target expansion intensification agriculture, contextualized for diverse social settings market foci north. However, rapid pace climate change means traditional methods adapting cropping systems developing...
Rock pulverization is recommended when converting boreal forests to agricultural land use facilitate tillage operations. Resulting rock dust incorporation might alter physical, chemical, and biological properties of soils. We assessed soil nematode trophic group abundances indices, basal burst respiration, phosphorus extractability after conversion (LUC) recent (<1 year) on three types in eastern Newfoundland, Canada. Nine treatments representing varied statuses (managed pulverized,...
Context Climate change facilitated expansion of agriculture into northern regions increases the amount Podzol dominated farmland. Biochar can improve poor growing conditions in soils. There are no universally accepted soil quality indicators for assessing sustainability expanding and intensifying boreal farming. Changes community structure inform on functional status impact management. Aims We assessed impacts biochar added to recently converted agricultural land nematodes. hypothesised that...
