Starts out with all the features of the Routine Test

Includes key micronutrient levels that are often deficient in arid/semi-arid Western US soil conditions (Iron, Zinc, Copper and Manganese)

Provides recommendations for deficient nutrients tailored to the plants the client indicates are to be grown (please provide this information on the submission form)

Choose this test if micronutrient deficiency symptoms are seen or suspected the previous season. Micronutrient fertilizer applications are most effective in the early spring--much less effective mid-season.
