GERMINATION AND NITROGEN

It is observed that the chances of seeds germination is found to be 20 to 30 percent in the soils with charcoal as compared to control soil (red soil).





CONTROL RED SOIL-------- RED SOIL WITH CHARCOAL

Probably we need to add more nitrogen to the soil with charcoal, as may be some part of the nitrogen is absorbed by the charcoal and some part might have been used up by the living microbes. Of course there is a chance that the remaining nitrogen is released by the charcoal slowly into the soil for the plants to absorb.

Note: The above comments are based on physical observations, in an open environment. No pesticide / fertilizer is applied to the soil organic or inorganic.

I notice the TP pot surfaces are darker. Cold this improve the temperature and encourage your seeds to germinate and grow?
