Dear scientists .. My compost piles were analyzed periodically for their contents of organic matter, nitrogen, ammonium nitrogen and nitrate nitrogen related to dry weight of samples, without weighing the whole pile each time .. then i can not know real total N and consequently total NH3 or NO3 to calculate true N loss as a prediction for GHG
Note that carbon loss in piles was parallel to apparent nitrogen gain that wasn't real .. as nitrogen actually decreased too.
Thanks a lot
An illustration for one of the results
you can take sample with time after 2,4,6,8...ect week or day
and get solution of compost by doing basta or weight 100gm and add 100 ml of water
pls see

Like the suggestion of Raghad Mouhamad we can determine the dry matter disappearance by creating 100 g dry matter samples as part of the compost pile at the progressing times the samples are dried and the disappearance of the weight is calculated. You should get a bathtub disappearance curve and this can used to calculate the real loss of N.
In relation to losses the biggest N loss is from volatilization of ammonia mostly in the first 45 days and secondarily by nitrate losses mostly from 45 to 90 days.
When having manure subject to volatilization lost the mixing of manure with 10% clay 2% gypsum and 1% humic acid will capture ammonia and greatly reduce losses. The use of sufficient straw ffor a base and covering is very important. By delaying during for 45 days and using the amendments the losses of ammonia can be minimized.
By turning gently ammonification losses are also reduced.
In terms of nitrate losses this is mostly avoided by having moisture at a loss that does not shred water facilitating leaching.
Hope you have good results with your composting.
