Atmospheric N deposition is known to severely impact forest ecosystem functioning by influencing soil biogeochemistry and nutrient balance, and consequently tree growth and overall forest health and biodiversity. Moreover, because climate greatly influences soil processes, climate change and atmospheric N deposition must both be taken into account when analysing the evolution of forest ecosyste...

B is one of the seven essential micronutrients Boron uptake by plants is controlled by the B level in soil solution required for the normal growth of most plants. rather than the total B content in soil. The affinity of organic matter for However, the range of B concentrations in the soil soluB can affect B uptake by plants because of changing B concentration in tion causing neither deficiency ...

the present investigation attempted to develop the ceramic adsorbent media in order to remove the mercury from aqueous phase. two ceramics, akadama volcanic ash soil-ceramic (aceramic) and improved magnesium oxide impregnated akadama volcanic ash soil-ceramic (maceramic) were produced from raw akadama volcanic ash soil by heating process to determine the hg(ii) adsorption capacity. adsorption e...

introduction: boron (b) is an essential plant micronutrient whose soil availability is influenced by many soil factors.understanding the processes controling activity of boron (b) in the soil solution is important for soil fertility management. the reaction of adsorption and desorption of boron in soil determines the amount of boron that is available to plants. adsorption–desorption processes p...

Vanadium, V, is a redox-sensitive metal that in solution, under aerobic conditions, prevails as the oxyanion vanadate(V). There is little known regarding vanadium toxicity to soil biota, and the present study was set up to determine the toxicity of added vanadate to soil organisms and to investigate the relationship between toxicity and vanadium sorption in soils. Five soils with contrasting pr...
