<div>What do you think is going on to produce such a tremendous improvement in the productivity of the biochar boosted plots? </div></blockquote><div><br>The paper on biochar to the mustard greens has not yet be published.<br>

<div>Are we sure the soil, water conditions, and cultivation regimes were otherwise identical save for the addition of 5 kg of rice hull biochar per m2 to the experimental plot?</div></blockquote><div><br>Yes, Dr. Thomas Reginald Preston does things in a thoroughly scientific manner.<br>

<div>I did not understand the 25% weight gain for cattle. Is that because they are feeding of biochar boosted pasture?</div></blockquote><div><br>Read the biochar-to-cattle paper carefully.<br>Dr. Ron Leng does an excellent job of trying to explain what is going on here.<br>

<div>If these results are factual and can be replicated both in Vietnam and elsewhere in the world, maybe rice hull biochar provides exactly what the soil in that area of Vietnam needs to improve its fertility. </div>

<div>What is the soil like where this test was carried out? Hopefully the researcher has done baseline and post biochar soil ferility tests.</div>
