Is anyone working on in-situ decomposition of rice stubble?
Both field and laboratory parameters.
Dear Borah,
stubble C:N is amajor parameter.
With regard to observations, i hope soil ammoniacal and nitrate nitrogen status at hourly/24 hours interval would help.
Thank you sir for your input. Regarding soil ammonical and nitrate nitrogen, can't we increase the time interval? Presently we are monitoring at weekly interval, as 24 hourly it becomes difficult to manage due to large number of samples. We are also monitoring dehydrogenase and phosphatase enzyme, would it help help in explaining the results?
Dear Borah
In addition to observation on microbial and C:N ration, record enzyme activity as well as decomposition rate using in-situ litter bag method. From this we can work out nutrient release pattern and dynamics also.
Thank you

Thanks sir. We are monitoring enzyme activity. We'll definitely go for in-situ litter bag method, that's really a good idea, thanks.
Sir,
In addition to above whether observation on no of days required for complete decomposition, amount of leftover, economics can also be taken ? I hope these observation is very important from farmers point of view the ultimate user.
