Too much compost in the garden a bad thing?
I am planning for next year early and looking forward to building several raised beds for my garden. I currently have a traditional row garden in a space of about 15'x25' and think I could do better with raised beds i.e. yield vs. space. I figure I will need about 300cu foot of dirt to fill the beds I want to use at the height I want. I'm currently composting a 4x4 pallet space and making good progress, just not enough to help out my raised beds at this pace. I have access to as much "brown" compost I want in the form of dead leaves that my city collects and turns into compost for all that want to buy. My question is can I amend/add/till 300 or so cu. feet of that to my current soil in the fall(zone 5) let it sit all winter and have it nice and usable for the spring/end of May planting. Or does that have the potential to ruin the soil for a year? Is it too much of a good thing?
