One of the best tools I ever bought for gardening is my push planter. If you do not have one check them out. Mine is made by Gardenway. You set the depth for your seed, use the correct seed plate and you push it down the row planting, covering up and fertilizing all in one pass. It also has a row marker that you set to mark your next row. You can also use it to side dress after the plants get up. It uses a lot less fertilizer than putting it out by hand.
