AGRICULTURAL NEWS - Adding organisms randomly and hoping that they will increase the soil’s organic content is like leaving livestock on bare ground and expecting them to thrive.
I once witnessed an entire district of vegetable farmers conned into spending millions of rand on compost tea before they realised this fact.
One farmer had his huge potato trial independently evaluated and discovered that he had suffered greater losses from rotting in the section where tea had been applied.
In any case, applying a few kilograms of bacteria will have a negligible effect as there are already tons of organisms in the soil. You might even end up causing harm by introducing pathogens.
