[Terrapreta] Beyond Zero Emissions interviews Dr Lukas Van Zweitan

Hi All,
 
Beyond Zero Emissions interviews Dr Lukas Van Zweitan senior research  
scientist of the NSW Department of Primary Industries (DPI). Who is working  hand-on 
with soil research focusing on Bio Char (Terra Preta de Indio / Agri  Char) 

Lukas Van Zweiten: "We actually harvested that plot this  week and we've seen 
some amazing differences. Its a bit early to give you the  exact data at this 
point in time, but we've seen probably double the biomass  production and 
double the sweet corn yield where we've had high rates of biochar  application in 
the soil. That's somewhere between 10 and 20 tonnes per hectare  of biochar. 
And, yeah, we've had some very, very significant differences in corn  
production there. 
We've also had a look at nutrient analysis in the leaf content, and again  
different biochars acting in the soil. I guess it's an interaction between the  
plants and the soil, but we're getting a very different uptake of nutrients 
into  the leaf material when we have biochar present. And we're also seeing  
differences in greenhouse gas emissions from the soil." 
"we've found with some of the biochars in that we've had very, very  
significant reductions in nitrous oxide emissions from the soil; between five-  and 
ten-fold reductions in nitrous oxide emissions."
