I have some potting soil and a bit of sea soil. How can I sterilize (kill the mold, especially) it so it isn't wasted and I don't have to buy more? Will it have nutrients in it after the sterilization?
You can place about 4 inches of soil in a shallow, oven-safe pan covered with foil and bake for 30 minutes at 180 degrees F. to sterilize the soil.
I have lettuce and greens in a bed where everything seems to be growing too slowly. Lots of red root pigweed, little grass blades, purslane, and lamb's quarters are coming up as weeds in there. I'm wondering if these weeds indicate any deficiencies or soil character? Earlier this season we tested the bed, it was still a bit acidic (5. 5 - 6. 0). We added lime and planted.

I want to let my veggie garden go unplanted this summer but would like to put nutrients back into the soil. What can/should I plant to help the soil become more healthy? Last year my tomatoes didn't ripen well at all. This would be the first in about 7 years I won't plant vegetables there.

I would like to make a raised bed for growing vegetables but know that the existing soil is contiminated with lead. Is there some kind of soil barrier I can put down and cover with healthy soil and grow veggies risk free?
Peat is thought to possess an excellent metal binding capacity. In addition to peat, gypsum and lime may be suitable as fixing agents in lead-contaminated soils. Cover this with layers of moist newspaper and then add soil. The most effective way to reduce the level of lead is to add compost and mulch as much as possible. There are also specific types of crops (like leafy greens) that you can plant and then dispose of prior to planting anything else. These plants naturally absorb large quantities of harmful chemicals, making them ideal to use them in order to soak up the unwanted toxins. However, remember not to ingest these plants—you must dispose of them and avoid throwing them into the compost pile. Also, keep in mind that lead only leaches downwards, so as long as your raised bed is 6-8 inches deep, most of your plants should be safe.
We have had a lot of constuction lately. The areas of the lawn that are shadowed or dirt have a lot of ant hills. How do I get rid of them, and what should I seed with to make sure I get my lawn back? The soil is a hard clay and sandy mixture in western Massachusetts. What should I treat the soil with?
