First foray into heirloom tomatoes

5. Here in Minnesota the U of M offers soil testing

through their Agricultural Extension service (if I remember correctly, there's an Extension office in each county - usually in the county seat). You might check with the county you live in to see if there's a similar service where you live.

Over the years I've had to "loosen-up" the soil in my garden. I've tilled in compost and, believe it or not, old potting soil from various planters. It's help a lot in the areas where it has been mixed in - water absorbs into the soil now rather than making a big, muddy, non-productive mess. I'll be tilling the old mulch in this year after harvest.
