Plant tissue sampling time is just around the corner. For wheat and small grains be sure to submit the entire plant prior to heading. For High tunnel tomatoes grown in soil we need the youngest mature leaf on the main stem at veg, bloom and fruiting stage. For greenhouse tomatoes grown in media or hydroponic we need the terminal leaf or leaflet next to the most recent fruiting cluster. We offer the Solvita test for soil, compost and manure.
