What is a bio-indicator plant?

Dialogue avec la terre

With GĂ©rard Ducerf, the botanist of our agricultural consultancies, a major aspect of our work is cheap essay writing services to analyse the bio-indicator plants : He is the creator of the technique which allow us to give a diagnosis of the soil, viagra usa with its components and its dynamic :

The advantage of bio-indicators compared with sampling soil to give to a laboratory is :

  • A sample of soil will tell you about the existence of all sorts of minerals, metals and chemicals : phosphore for example. You will be happy when the lab tells you that there is… but exactly where you can find phosphore, can grow the false rockett salad Diplotaxis tenufolia…

    which indicates that the soil is compacted, with a dominance of chalk and phosphorus which is totaly blocked, inactive… All the phosphore fertilizer you have been spraying there has been bloqued by chemical reactions. The money you have put there has been of no use.

  • Just imagine sampling ground on 100 000acres … Even on 300 acres you sample ground on specific spots you have chosen; on a scientific point of view it is not because you have sampled there that the whole soil of you field will look alike. It is not very not a very serious diagnosis.
  • According to temperature, humidity, biomollecular interaction the sample will evolve by the time you will bring it to the lab. Yet all the undergrown bacterias are dead, and the composition can differ on the way, with any thermo choc. On the other hand the plant is there and indicate to you the exact condition of your soil and where ot is heading to.
