Phosphate efficacy in no-till wheat amended with biocarbon 2009 locations
Aims

To investigate biochar’s agronomic potential in field trials. 

Key messages

SANTFA’s 2010 field trial in calcareous cropping country near Streaky Bay demonstrated the strongest evidence  yet for biochar’s capacity to influence fertiliser efficacy and crop yield in SA’s cropping system.

The biochar data collected from the 2010 trials is analogous in many ways to what we would expect from spreading clay on non-wetting sands: little response at very low rates, an excellent response at the appropriate rate and a potential problem if the soil is over-clayed or the wrong clay (such as a limey clay) is applied.
