Question

The introduction of the "four field rotation" in agriculture had what effect on the industrial revolution?

Answer 1

Production of more food--the system allowed for more food to be produced which fed the workers in an industrial economy. 

The 'four-field system' rotates crops between the 4 fields no longer needing to keep one empty because one of the crops would replenish the field with nutrients while the others take nutrients away from the fields. <span />
