i bought a soil test kit at Lowe's. It tests for pH, nitrogen, and 2
others. It has 4 small bottles and what looks like a pill inside the
bottle. Are those reliable or should i take the
soil to my local extension?

Also, i just fertilized my lawn last week. Should I wait a couple more
weeks before doing the
soil test? I don't want to skew the results, because the fertilizer I
applied was nitrogen heavy.
