Why farmers need to know how basic or acidic the soil?

Plants grow better in soil with the PH (acid-base) they have adapted to. The acidity or the alkalinity of the soil is important to know in order to grow a particular plant. Some plants want a acidic soil and some want a basic soil. However, most plants prefer a neutral to slightly alkaline soil. So, it is important for the farmers to know what type of soil it is in order to balance or neutralize the soil. They should know what type of inorganic substance/fertilizer to add in order to neutralize the soil.

Is it better to build on rock hard soil or loose soil?

You haven't said what you are building. Possibly it should not be built on soil at all, but should be built on bedrock. You don't want to build something on soil that is too loose because the soil could shift, and your structure, whatever it is, might tilt, or sink into the soil to some extent. Better still, pour a concrete foundation, and build on that.
