Amendment Rate Units
Fertilizer Class 'Details' shows the biochar application rate that would needed to meet the nutrient requirements of an average corn crop. Choose whether you want this amount reported in U.S. tons/acre or metric tons/ha.
In U.S. units, Ca5t means that 5 U.S. tons/acre are needed to provide enough Ca to meet the corn requirement.
In metric units, this would be equivalent to Ca2t, or 2 metric tons/ha.
