If assumed or inferred no filler material,
'potassium'            2x
'iron'                  x
nitrogenous iron       3x
Total                 60 pounds

2x%2Bx%2B3x=60

6x=60
x=10

MATERIAL             POUNDS

'potassium'            20
'iron'                 10
nitrogenous iron       30

Total                 60 pounds
