I have to give 120mM NaCl treatment in field condition for fennel crop
I suggest to you to use ppm instead, it is easier to use and to understand by readers.Wish you luck.
But why? See the previous question: https://www.researchgate.net/post/What_is_the_importance_of_application_of_salt_NaCl_in_field_is_it_to_apply_or_not
I assume you mean 120 mM in the irrigation water, not in the plant tissue? This question is simple high school chemistry isn't it?
- 1 mol of NaCl is 58.45 g.
- 120mM = 0.12 mol = 7.014 g of salt per litre.
- Area of land is 20 m2. Assume a depth of 10 cm (0.1 m) water = 100 L per m2.
- 20 * 100 = 2000 L * 7g = 14 000 g
Why would you want to add 14 kilograms of salt to otherwise perfectly good soil? It is well established that salt is not good for cropping. There is much more effective science to be done than reproducing existing knowledge, even if you are studying a different crop (fennel in this case).
I have to give salinity stress in fennel crop for research purpose@Mathew Wheal
Like Matthew said we need to know what you mean by 120 mMol NaCl concentration. It that 120 mMol/liter in the irrigation water?
In that case it is not difficult. Weight of NaCl is 22.990+35.453 (atomic weight of both elements)=58.443. This means that the weight of 1 mol is 58.443 gr
1 mmol is 0.058443
120 mmol = 120*0.058443=7.013 gr
So need 7.013gr NaCl/liter if you want to give 120 mMol NaCl/liter.
Thanks...But how to calculate the amount of irrigation water required for 20m2 area field @Herman Eijkelboom
so then you want 120 mMol NaCl/liter in soil?
That is difficult to calculate.
