Do you know you put your question in the Lawn Care forum? If you want to know if your soil is right for a lawn, then this is the place to find an answer.
Since you mentioned crops, though, I wondered if you're asking about veggies and/or flowers, I can move your question for you. Just let me know what kind of plants you want to grow.
