[Terrapreta] Florida Sand

[Adriana Downie]

Hi Jim,
 
We have done trials on some Australian sandy soil with good yield
results. We have found with trials we do on 'good' soils that there is
much less significant or no improvement in yields, however there is
still a significant increase in fertiliser use efficiency and a decrease
in nitrous oxide emissions. This work has been done in collaboration
with the New South Wales Department of Primary Industries and
publications of these results are on the way.

Does anyone know of any trials of biochar on Florida sands?
 
Is it true that biochar is un-likely to improve yields in soils that are
pretty good already (loams)?
 
I would like to see more results on crop yields can anyone point me to
links?  
 
Jim
