Answer: Most vegetables need full direct sun all day long to grow and produce well.
The soil should be looosened down about a foot and compost or other organic matter should be added. You would also want to run some basic soil tests to check fertility and soil pH, then add fertilizer and/or lime as indicated by the test results. Then once the soil is prepared, use an organic mulch on top of the soil to help protect it from erosion and hold down weeds. This will also help add organic matter to the soil as it breaks down slowly over time.
If planting in August for a fall crop, you might consider cool season growers such as spinach and other greens, peas, onions, cole crops. (These can also be planted in the very early spring alogn with radishes which need cool soil to grow well.)
The so called main season vegetables such as cucumber, squash, tomato, pepper, eggplant all need a longer growing season than we have left. They would be planted next spring after all danger of frost has passed.
You might still be able to plant a fast maturing variety of bush bean now for fall harvest, and you could also consider planting a cover crop to help build up your soil for next year's planting.
