I produce food, not run experiments using various percentages of char, different formulations, and using controls. In addition, I use a number of soil amendments including char, mulch, compost, crushed bone, crushed coral, lava dust, and generally any animal and green waste that comes available. None of my field is amended by biochar alone. I also make and use foliar sprays when plants show need.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:black'>Having said that, I saw visible improvement in the areas that I started using biochar. The plants were visibly more lush and withstood dry conditions better. My own reasons for adding biochar is that it tends to even out the soil moisture retention capabilities of the soil. The areas that became boggy now drain better. The areas that moisture levels fluctuated wildly now tend to flatten out somewhat, staying much more evenly moist. In my own situation, I found that leaving the char chunky ( 1/4 to 1 inch) works just fine. <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:black'>I had noticed that plants looked more lush when planted into ground that had a fresh application of char.
