Soil testing

When it comes to soil testing, soil samples should be taken from the same areas as the tissue samples. For strawberries, raspberries and grapes, the sample should be taken to the side of the plant row, but not at the center between the rows. For soil testing in tree fruits, take the sample within the drip line of a tree and within the vegetation free area. Sample should not be taken from the sod area. Take individual samples with a small shovel. A good sample consists of about 8-10 subsamples, taken to 6 inches per area. Organize the subsamples by mixing and placing about 1 cup of soil in a soil bag or pint plastic bag. Identify the bag with the same sample number as the corresponding tissue sample. Tender the soil sample along with the tissue sample for analysis to the lab scientist of your choice for the soil testing.

Soil analysis should always be part of the preparation of site before planting. Because fruit plants are relatively long in lifecycle, it is necessary to amend the soil prior to planting. Take soil samples from the site a year before planting, apply and deeply incorporate any fertilizer or lime recommended. A soil test is the only practical means to determine which and how much fertilizer or lime are needed for best growth. Evaluating soil fertility is a good practice to establish in order to make most efficient use of applied fertilizer.
