Incubation study of soil and biochar and changes in soil EC (electrical conductivity) throughout the incubation period.
First, you need to compare your outcome with your null hypothesis, which would be there is no effect of Biochar on electrical conductance, or that addition of Biochar would have the same effect as a control (distilled water). There obviously is an effect of Biochar, so you can reject your null hypothesis. You then have to set up new hypotheses to determine why you obtained your results. For example, you could examine electrolyte changes. Otherwise, if you just pluck explanations out of the air, you are guessing and it is unscientific :)
@ Nayem, EC changes by adding cations and anions. So, with increase in time of incubation may be organic matter is releasing from the biochar which help in increase your EC. From your result, I guess the maximum release of organic matter from biochar you are getting at 20 days.
What was the design, randomisation, replication? In other words, are these differences statistically significant?
J. C. Tarafdar Thank you so much. What could be the reason for decreasing the EC value for the control treatment from 10 to 20 days?
@ Nayem, may be the ions from the control soil is decreasing from the solution during 10-20 days time. It also indicate the low available nutrients in the given time.
J. C. Tarafdar Thank you, Sir. It would be great if you provide me with some reference papers regarding the case.
And in your first comment you said that "From your result, I guess the maximum release of organic matter from biochar you are getting at 20 days." Can you tell me a little bit more about it so that I can get the full concept regarding the mechanism?
Stay always safe.
Regards,
Nayem
