Had a bunch too. Nothing wrong with using pine logs here.
I didn't have time to dig swales or anything so I decided to go the slow approach as an experiment. We laid the logs (about 100 feet worth) on contour on a south facing slope thinking we'll chop and drop anything along them and eventually we'll have some contours on the slope.
I did bring a few yards of soil and spread about 4" of soil on the downslope edge of the logs, one or two shovels wide. Just enough to make a slight
berm to hold
water back from flowing freely.
Sprinkled some leftover seeds in the soil, radishes, turnips, borage, Daikon, one amaranth came up (red). Mulch on the seed bed.
Everything is very lush downslope of the logs, the logs themselves are rotting nicely and I guess creating an edge effect. All sorts of wildlife started showing up that you never saw there before, frogs and snakes and birds in the first year.
Picked a few turnips and radishes but mostly left everything to go to seed.
This pic is the late summer of the first year, 2014. Logs laid in early spring. I have trees planned for this in a year or two and another row of logs 20 or 30 feet farther downslope eventually.
