Updating multiple rows with value of other column

Hi all,

I have a table with 712 rows.
One column from row 545 onwards to row 712 is empty and needs to be filled with the value from another column in the same row. On top of this, this value needs to be multiplied by 0.0672.

So, there is a column called 'Nitrogen' which (from row 545 until 712) needs to be filled with the value * 0.0672 from the column called 'Humus' in the same row.

Can anybody provide me with an answer?
Thanks very much,

Joe A
