Modern agriculture is facing twin challenge of ensuring global food security and executing it in a sustainable manner.However, the rapidly expanding salinity stress in cultivable areas poses a major peril to crop yield.Among various biotechnological techniques being used to reduce the negative effects of salinity, the use of arbuscular mycorrhizal
The aim of the study was to determine the effect of soil fertilising biopreparations, i.e.compost extract, vermicompost extract and humus extract, used against the background of NPK mineral fertilisation, on the content of manganese, iron, zinc and copper in the biomass of Lolium perenne, Festulolium braunii, and Dactylis glomerata.In the spring of
Sequential sampling of rainwater from Hurricane Irene was carried out in Wilmington, NC, USA on 26 and 27 August 2011.Eleven samples were analyzed for pH, major ions (Cl−, NO3−, SO42−, Na+, K+, Mg2+, Ca2+, operation igloo white NH4+), dissolved organic carbon (DOC) and hydrogen peroxide (H2O2).Hurricane Irene contributed 16% of th
