Re: [nafex] Fruit trees -- high water table

Just a short comment on Rivka's last paragraph. Wood chips are relatively high in carbon with respect to nitrogen, so will temporarily tie up nitrogen — but only if mixed into the soil. Laid on top of the ground, breakdown is gradual, and at the interface of the mulch and the soil. A dynamic equilibrium then exists where tie up of nitrogen is offset by its slow re-release into the soil. This is not just theory; I've used wood chips as mulch for decades, always with good results, and have talked to others with similar experiences. The same could even be said for sawdust, which I've also occasionally used as mulch.

Lime will need to be applied from time to time, but it's unlikely to be needed every year. Getting it worked through the soil takes time, especially if you're not tilling; but you could probably get some of it worked in while digging planting holes.

For orchards generally you should do a subsoil sample as well as a sample taken nearer the surface. Your county extension office should be able to give you instructions for taking the samples, and may even be able to do the tests.

And check what pH is recommended for the particular species you're planting -- quite a lot of fruits (and for that matter vegetables) either prefer or comfortably tolerate a slightly acidic soil.

If you've got an area you expect to plant in eventually but not for some years, you could spread high-cellulose stuff over there. If you'd be living there and heating with a wood stove, note that wood ash will also raise pH, as well as return some other nutrients to the soil.
