There were some parameters to describe root distribution in the soil profile. One of these parameters is specific root length
There is hardly any instrumentation which can measure root distribution non-destructively . but root scanner will involve minimum disturbances in roots fro working out the root configuration . You will have to make different grid sections within the plant rhizosphere and take samples at various horizontal and vertical depths through core sampling .
I don't think you can use specific root length to describe root distribution in the soil profile as it is the ratio of length to mass.
Dear Mahgoub,
Measuring the total volume or total weight of root plants may be sufficient to compare and achieve the goals. But for a specific root the largest root according to the length and diameter could be measurable and useful for herbaceous plants.
What do you seek to accomplish? A little information for clarity purposes could facilitate more detail response and suggestion. I am not sure if there has an article on using root length to explain the distribution in the soil profile. What kind of plant are you using in your project in the first place? At what depth are you focusing your test/analysis. Different plants have different root systems and all have different depth.
Thanks for your responses
Root length density is the major parameter I have to calculate, so I calculate root length and I want to calculate specific root length as an indicator about root fine roots
Is there is any calculations for the description of roots???
The plates I have used are faba bean, onion, maize and cowpea
