The Micronutrient Test measures soil pH (acidity/alkalinity), percent organic matter, phosphorus, potassium, magnesium, calcium and the secondary and micronutrients; sulfur iron, zinc, copper, manganese, and boron. These are all of the important nutrients in the soil to support plant growth. We like to recommend this test when there is a persistent plant problem requiring diagnosis, when a lawn needs renovation or when starting a brand new garden; especially fruit and vegetable gardens where nutrient supply is critical for fruit production.
