many samples do I need to collect?
advise you, the homeowner, to test each area that you fertilize
separately. You may fertilize differently because of significantly
different soil types or for plant material with differing nutrient
or pH requirements. For example, if want to test the soil from your
lawn and you are willing to do anything it takes to make the front
yard beautiful, but you aren't willing to spend much time or money
on the back yard, we suggest that you send in one sample from the
front yard, and one from the back. However, if you employ a lawn
care company and you know that they apply the same treatment on
the front that they do on the back every year, then you would only
need one sample tested which was made up of soil from both the front
and back lawn areas.
Along the same
lines, if you have one large garden, you may want to submit more
than one sample. If, for instance, you have a section which is only
tomatoes and you are willing to fertilize this area differently
from the rest of the garden, you should send in one sample from
the 'tomatoes only' area, and one to represent the rest of the garden.
you might consider sending in more than one sample would be to help
troubleshoot a problem area. For example, if most of your lawn is
beautiful, but there is one spot that just won't stay green or thicken
up, you may be able to learn something by comparing the test results
from the healthy area with the poorer area.
