Aluminium Toxicity Targets in Plants

Aluminium (Al) is the third most abundant metallic element in soil but becomes available to plants only when the soil pH drops below 5.5. At those conditions, plants present several signals of Al toxicity. As reported by literature, major consequences of Al exposure are the decrease of plant production and the inhibition of root growth. The root growth inhibition may be directly/indirectly

Are we ready for the next Chernobyl? | Interviews | …

2020-6-13 · The nuclear reactor meltdown at Chernobyl may eventually cause over 40,000 deaths through cancer, and the area is still uninhabitable. Nuclear power is still used around the world, but what do we do the next time the worst happens? Graihagh Jackson has been investigating an idea called ''bioremediation'', the use of nature to clean up spills or contamination.

Soil Nutrient Analysis: Nitrogen, Phosphorus, and

Nitrogen is extracted using calcium sulfate; phosphorus and potassium are extracted using Mehlich 2 solution, a solution of acetic acid, ammonium chloride, hydrochloric acid, hydrofluoric acid, and demineralized water.Boundmacronutrients present in suspension can then be separated from the remaining solid soil components by vacuum filtration.
