What are the consequences of elevated Carbon Dioxide on soil organic carbon pools?

Which micro-organisms have potential to be used as bio fertilizer to specifically fulfill nitrogen requirement of the soil in sustainable agriculture?

Currently I am doing adsorption studies with four types of biochar prepared from four feedstocks. We evaluate adsorption performance by TOC reduction in grey water. I noticed that after putting biochar into the grey water sample, the organic carbon content showed sudden increment, indicating that biochar is releasing organic matter into water. How to consider this phenomena when analyzing the results?

Thank you so much in advance

It is known that soil texture does not change easily, but the effect of soil tillage, soil fragmentation and the passage of agricultural machinery over it, will it affect the soil texture over hundreds of years?

Dear Scientists,

During the composting period. Is there any fixation of nitrogen?

Which genuine or species of earthworm are good for preparing vermicompost?

Soil and Biochar were incubated for 30 days at 10 days of intervals.

Results:

Level of soil pH: 10 days>20 days<30 days

Level of soil TOC (Total Organic Carbon): 10 days>20 days<30 days

Note: pH and TOC at 30 days were not higher than 10 days of incubation.

What could be the explanation for higher and lower at different incubation periods?

Regards,

Many of us think that if we add more organic matter to soil, crop productivity will be increased accordingly. But all soils capacity to hold or to receive organic matter are not the same.

I would like to know the opinion of soil researchers about improvement of saline soils by application of biochar. Is biochar really helpful to decrease salt in the soil? how is it going on with osmotic pressure?
