Organic matter in soil decrease day by day. We should increase om in soil. Do you think that green manuring is the best option to increase om in soil.
The soil carbon sequestration was significantly higher in the Biofilm biofertilzer practice. This is due to increased microbial C assimilation in the root zone if the soil.

Yes, green manuring increases soil organic matter.
Chapter Green Manuring and Its Role in Soil Health Management
Green manure (GM) helps in the expansion of the soil nitrogen source, the mobilization of soil phosphorus and the improvement of soil organic matter content in the soil.

Despite such conspicuous changes in soil organic carbon content in response to green manuring , why is this a forgotten cultural practice in modern day agriculture...??
Regular application of green manure will lead to an increase in soil organic matter but do not expect that build-up of soil organic matter is permanent. Once we stop applying green manure, soil organic level will start decreasing and reach a level as regulated by climate and tillage.
the effect of green munure on the soil organic matter depends on when is it incorporated into soil. if it is incorporeted into soil too early and too young of seedling, I don't think it is could increase soil organic content.
Yes, obcourse. Green manuring crops increase organic matter to the soil. For this purpose leguminous plants/crops may play more effective roles.
Yes, green manure increases soil organic matter. Then maintenance of the soil density level.
it depends on the C:N ratio of the green manure which use to incorporate. The humus content is only increased appreciably if material fairly resistant to decomposition is added to the soil (high Carbon:Nitrogen ratio), and this type of plant material is typically low in nitrogen (less than 1.5 per cent on a dry-weight basis). The available nitrogen supply is only increased if readily decomposable material high in nitrogen, such as immature green plants, is incorporated into the soil. The amount of organic matter that may accumulate will vary with the soil, climatic conditions, and the age and type of crop.
Increasing organic matter in a soil upto a certain degree is not that difficult but depositing into passive pool of soil carbon is the real success and add recalitrance to such carbon against decomposition losses...
biochar is the best organic source to maintain soil organic carbon in passive pool form for long period in soil
That's is good idea to increase OM in soil by green manuring to increase fertility of soil
Strictly speaking, green manuring is not able to increase organic matter content of the soil. Well, soil organic matter (SOM) level is defined by the prevailing climate at the location. When we repeatedly green manure a field, SOM does increase but temporarily. Once we stop applying green manure, in a couple of years the SOM reverts to the original level as defined by the climate.
I agree Dr Bijay Singh Sir, ex-situ long-term application of green manuring would beneficial to increase SOM.
The quality of the organic matter that we add to the soil depends on the ratio of nitrogen to carbon. Therefore, poultry waste comes first, then leguminous crops as green manuring
Green manuring can increase soil organic matter content, but temporarily. Soil organic matter content is governd totally by the prevailed climate. So you need to practice green manuring yearly or even seasonally in unfavorable climate to maintain its level.
How the recalcitrance of added carbon works in a given soil is perhaps most important to enrich the passive pool of soil organic carbon vis- a- vis crop perormance....

Overall SOM regulated by the climate of a particular location, Continuous green manuring will temporarily improve the SOM.
Green manuring either insitu or exsitu may improve soil organic matter.. logically, green manuring crops which were grown in the field, mature and are buried in the soil by tillage operations is more pronounced to raise SOC status.. however, good capacity to fix atmospheric nitrogen also add nitrogen in the soil, resulting in efficient release of nutrients for plant uptake...humus formed as final product after decomposition of organic matter added by insitu green manures may also act as chelate for enhancing the micro nutrients availability in the soil...over all, it has been conceptualised that addition or inclusion of green manuring crops influence all the physical chemical and biological properties of the soil in a positive manner...Dhaincha and rice co culture is very popular strategy now a days to sustain the soil ecology
