Preparing for more rows

I am preparing for 3 more rows.   We measured out the rows.  They are 50 feet long and 3 feet wide with a 22 inch walkway.    We are spreading out a thick layer of compost that will be tilled into the existing soil.  The existing soil has a lot of clay, so the compost will add organic material and improve drainage.   Here are some pictures of the rows and my part time helper - Dominique dumping compost.    There will be 20 rows along the back wall when we are finished and room for 3 or 4 100 foot rows where I am standing to take the pictures.     The corral is about 1/4th of an acre so I can grow a lot of vegetables in that space.
