boiling the soil would not do the same thing. Water at sea level will not go to temperatures above 100 Celsius unless it is put under pressure. So 100 degrees will not kill the bacteria and really wont do anything. You use a pressure cooker which allows the pressure to get really high, which in turn keeps the water in liquid form at very high temperatures. This will kill the bacteria it is acutely the same principal behind autoclaves which are what sterilizes surgical equipment. This would also kill all beneficial bacteria and I don’t know if it is a good idea. What I did was buy some really good soil with lots of micro organisms and mixed it with other soils. My theory is that they will just multiply and spread through the soil.
harris7 Reviewed by harris7 on . pressure cooking soil (juice) this is something i actually tried and had seen with my very own eyes but i want to know from another persons perspective? =get some good or used soil your choice place in a mason jar with lots of water more then needed, put lid on fairly tight place in presure cooker, cook for 45 mins, let it cool for how ever long you'd like couple hours or even a few days = strain out the soil and use that water for your plants. (the pressure cooker kills all the bad stuff leaving eveything in the jar Rating: 5
