the terra preta,was really informative,,since begging of time folk has used this method of char to build workable soil,and looks like bottom soil from way down south,,full of goodies that give life,,im so pissed i cant make any char right now because of water restrictions in my area,,i have a 500 ft well,water isnt the problem,but the burn ban is,,so in close future im going to build one them tin man that you will see on the living web vids,make my own shit in a control burn,,you will see ,i watched both there long ,about a hour each but you will be inspired after watching them,i was,,ive used ash for 30 yrs to the garden and really didnt know much about it overall,but knew it helped in y garden a lot,,soil base gardens most of my life,,but the char is another critter to admire,,it soaks nutrient from soil and holds on to it,when the plant is ready it takes it,,the char just keeps on going,,i recently told JIPP about this method so she gave a try and just the other day she was telling me the difrence is very recognisable,you will have to excuse my spelling ,i cant lmao
