Prompted by poor size on the tomatoes...

I bought a soil test kit and found that PH is 6.5 7.0 = Generally
Acceptable.

P and K were high but N is depleted. Which explains the poor fruit
sizes?



My understanding is that N will always show low on soil tests. Plants use
lots of it and what's left over eventually leaches out of the root zone (and
possibly into the groundwater). Others are correct about taking care not to
add too much nitrogen to tomatoes or you'll get lots of green and little
fruit.

You can add nitrogen back to the soil by fixation or fertilization. Legumes
take atmospheric nitrogen from air in the soil and convert it to a form
plants can use. That might not help you right now though. You can use
organic fertilizers like fish emulsion or fresh manure if you don't want to
go with a processed fertilizer. Best suggestion is to contact an extension
agent for advice since they are familiar with your climate and soils.
