|Summary:||We walk around on soil all the time, but how often do we think about what's in it? If you have ever looked closely at soil, you probably saw that it is made up of various types of particles and has various materials mixed in with those particles (rocks, twigs, water, air, worms, insects, and much more). Those things you can see. But did you know that soil also contains things that we can't see and can only measure with chemical tests? These things -- acids, bases, nitrates, phosphates, and potassium -- are chemicals that affect what types of plants will grow well in the soil. As a citizen scientist, you can use a soil test kit to find out how much of each type of chemical is in your soil.|
