The numbers mean N-P-K (nitrogen, phosphorus, potassium).

In this case you have 0.15% nitrogen (as water soluble organic nitrogen as a
chelated agent), no phosphorus and no potassium. You will also have some
chelated iron, and small amounts of chelated and soluble manganese, chelated
and soluble zinc, and trace amounts of boron, chelated copper and chelated
molybdate.
