Soil Testing for Vineyards in South Dakota
Not all soils are conducive to growing quality grapes, so prospective vineyard sites should be tested before a decision is made to plant grapes. Tests can identify soils that are either too high in pH, salts, or salinity, or that are “too rich” (too high in organic matter and nitrogen) for grapes. In addition, testing before planting allows for the incorporation of nutrients—such as phosphorus—that do not move easily through the soil to plant roots.
