Welcome.

An acre is a pretty good size parcel when doing it by hand alone. If it was square, you are looking at about 70yds x 70yds. Generally, planting log roads alone does not do much except offer snacks - limited sunlight limits forage growth - hopefully the landing area is more open.

You need to do the soil test, it will give you a place to start. You are likely going to find it Acidic (low Ph) and very low in organic tilth - It could be high in nutrients however.

For a first time plot - I always reccomend a Fall planted (August in the North) Rye, or winter wheat plot - with alot of lime. You will have a great fall plot - and it is VERY forgiving on first time planters.

The soil Ph will not have to be perfect, you will get good organic buildup Early next summer (Rye roots especially) - At that time you can till it under again (or spray & mow) Then you can plant a clover - which will offer more forage all year and higher protein levels.

Rarely would I reccomend clover for a first time - woodland plot.

Good luck.
