You got that right about the soil here. It's low in organic matter, heavy on the clay composition, and highly alkaline. On the bright side it's high in minerals. It took me a good 1-2 years of growing cover crops to get the tilth about right and now it's pretty good. The chicken manure compost certainly helps with the NPK. If you decide to do any gardening you'll hear a lot of people talk about raised beds, but raised beds are good for places where the soil doesn't dry out in time for spring planting, like back east. Out here any plants in a raised bed will require 3x the water to keep them moist. I think the reason people use raised beds out here is because they don't want to work the soil to make it decent. Not saying there's anything wrong with that philosophy since different people have different amounts of time to dedicate to gardening here, but I hate hearing how raised beds are better in the valley because the soil is so poor which ain't necessarily the case - just takes some upfront work to get it going and maintain it but it's no different than difficult soils in any other part of the country. If anything it'd be better to make a depressed bed to retain moisture. Above all, feed the soil to bring the pH down to as close to neutral as possible - that's probably one of the main things. Also I always recommend growing crops that tolerate alkaline soil, such as corn, beans, etc. Sorry for going off on a tangent but I love growing vegetables.
